Woz on flipping green houses

Op-Ed: Apple Inc. co-founder and legendary hacker Steve Wozniak [book review] recently found a new passion in energy-efficient housing. Last month he told PC World magazine, "I have a long dream to build my own house in a very energy-efficient approach. That's going to be very soon. It uses the right kind of wood that serves as a heater and as an air conditioner, combined with some other techniques in how the wood is assembled to operate energy life pressure. You don't have to add energy into a house after you build it. I love that concept. It's like the way I used to make computers. I want to build it myself. That's a project that could be finished this summer, next summer, but not too far from now." Here at ECN we thought you'd like to know more, so we interviewed Woz by email. Here is a transcript of our questions and his answers. His preface: "I'm too busy to do this [interview] now, but I'll do it anyway. I have to say that I'm not a green expert but did encounter some technologies that were very right for a home."

ECN: Steve, thanks very much for your time. Here are nine questions for you, based on the PC World blurb. How and when did you become interested in energy-efficient construction? Do you have any plans to use your house as model for encouraging other people and companies to design their buildings more cleanly?

Woz: I am looking for sites but haven't had enough time to narrow one down yet. I'm mostly interested in areas of the California coast, like Half Moon Bay or San Luis Obispo. ... I have always had an interest in my own self-sacrifice to help the environment. I gave much money to groups working for forests and rivers. But I was probably misguided. I have no idea how effectively my money was spent or if it helped save one more tree or patch of river for future generations. Still, most of our charitable giving is in the sense of feeling that we are in some category we want to be in.

The term "energy efficient" is rather vague. At some level it implies some form of conservation. I have great reservations with that concept as well. One aspect of conservation is to use less so that there is more to go around, either to more people or for a longer time. I disagree with this concept pretty strongly. Personally I want to conserve but I wouldn't push that concept on others as a "right" way to live. I only want to serve as an example. I don't want to tell others that they are bad people or doing "wrong" things. That's not a good way to keep open communication. I also have trouble with the concept that we can have more of a "worse" life. It's a conflict between quality and quantity and life should be judged by quality.

The form of energy efficiency that appeals greatly to me is the idea of efficiency of construction. I have always admired getting the same results with fewer parts or procedures. That's a win for everyone. I used that concept in my design approach in life. I was determined to give my highest regard to engineers and in engineering we always strive for more efficiency, defined mathematically as more out for less in. If you can build a car at the same price, with the same features (size and performance) yet it uses less gasoline or pollutes less, that's a win for everyone, including the car manufacturer. Engineering leads to such advances, even when they seem like tiny steps.

Now, let's get to your point of energy efficient homes (or other facilities). I see two main parts to this issue. The first is using techniques to build homes with the least energy usage (and the least pollution). For example, ram-dirt is a material made of the dirt dug under where your home will be. It uses less energy than any other building material form to create, with a machine right at the construction site. Saving energy is good also in the sense that the energy to make this material usually comes from burning coal and emitting pollutants into our air. When properly applied, this form of construction is very low cost but applicable to luxury homes. I have spoken to builders who build luxury homes out of this material and have friends who are starting a company to manufacture blocks of this material for delivery to the site when the ram-dirt method cannot be used due to soil properties. This material is manufactured with grooved shapes and nails are not used in the construction. A home made of this should last 500 years, not just 75 years.

The other form of energy efficiency in homes is in how much energy your home uses to operate. We emit more pollutants such as carbon dioxide in our homes than in our cars. That includes the coal burned to provide our electricity, but there are other reasons that homes are responsible for such emissions. If you can build a home, with the same effort and cost, that uses less electricity, it's a win for everyone and any engineer can gloat.

Recently I was a judge at a History Channel Modern Marvels Invent Now Challenge in association with the Inventors Hall of Fame. A few of us judges were really taken by the winning entry and I suspect that more than myself are moving toward building the sort of home that won.

You build a home out of a type of wood that keeps the temperature constant without air conditioning or heaters. The miracle wood in this category is Southern Yellow Pine. As for renewable resources, more Southern Yellow Pine trees are planted each year than are used. I'm told this is the only tree with this benefit. The Southern Yellow Pine has a resin inside that melts and freezes at 71 degrees F., a very comfortable temperature for humans. The chemical actions of melting and freezing work to balance the temperature. If it's a hot day, some small amount of the resin melts (it takes a huge amount of energy to melt a tiny amount) and the melting process pulls heat from the surroundings, from the home. When it gets colder at night, the resin-wood emits heat as it freezes.

In high school chemistry we had the latent heat of fusion concept. You let ice settle in water. You can measure the temperatures. The ice and water are both 32 degrees F. It seems like the tiniest amount of energy would cause the ice to melt. After all, you only have to change it maybe a hundredth or less of a degree. But it takes a huge amount of energy to accomplish melting. This represents the difference in energy between the solid and liquid states. In this way, large amounts of energy can be stored. In the case of Southern Yellow Pine, energy from the summer can even be stored in the wood until a later season in some cases.

This company Enertia prepares blocks of this Southern Yellow Pine with grooves and sells the pieces as kit homes that you build yourself. The only tool you need is a power drill. No nails are used in the construction. I suspect that's because the metal of nails helps outside temperature conduct to the inside. The homes are also designed in an envelope fashion with 2 layers of wood and a space between them for natural air circulation around the home. The Southern side is all glass to collect sunlight. The homes are designed for more sunlight getting in during the Winter, when the sun is lower in the sky, than during summer, when the sun is higher in the sky.

All of these simple principles wind up with a very attractive house that is as normal and livable as any other, but without insulation or air conditioning or heating. The typical energy bill might be as low as $30 a month, depending on where you live. The outside temperature can be 50 degrees hotter or colder than the inside temperature of 71 degrees.

Recently I bumped into the builder of my first home. We reminisced and I told him of my plans to build one of these Enertia homes. He had built many homes with the efficient ram-dirt process and for one of them he used the resin-wood (presumably Southern Yellow Pine) for the roof. With only the roof being of this resin-wood the temperature inside never varied more than 5 degrees he told me. So the combination of approaches is one thing I'm considering too.

I like things simple with fewer parts and fewer added technologies. Just think out the right ways to build a home and do it. So few people know how easily all our homes could have been energy efficient rather than energy wasters. I suppose it's an outcome of the fact that energy is so cheap and abundant now. I think of it this way. The timeline of history and of man will be many millions of years long. Over that timeline, at some point man was going to find oil and ways to use it. Whenever in time that had happened, the generations it happened for would have used it up. We are those generations using it up, but if we saved it and didn't even touch it at all, some future generation would quickly use it up. The time that mankind has oil may be a short blip on the long timeline of humans. Whenever the discoveries were made, that blip would have appeared. We needn't think of ourselves as bad just because we were the lucky ones to have the oil blip.

ECN: Many experts say the clean-tech industry is today where the home computer industry was 30 years ago, where it's just a couple of companies and many amateurs. If true, what can the clean-tech industry learn from it?

Woz: No, it's not comparable to personal computers. Personal computers didn't have to tear down an infrastructure. Even if a few people like myself are building energy efficient homes (and a ton more are building things that are barely energy efficient or they are using one thing that's energy efficient in a very inefficient home that swamps the gains) we are moving out of our inefficient homes, selling them to someone else. So only new homes can be built this way. It will take many decades or centuries to replace the existing inefficient homes with efficient ones. The best you could do is to tear down an inefficient home and replace it with an efficient one. But few of us can afford to do that. It's normally done out of vanity instead - to build a home the way you want.

Eventually the word will get around and good examples will be noticed.

I do fear that big companies will build inefficient homes in other countries for the sake of making money. Those people will be stuck with homes that would cost a lot to air condition. If the right technologies were exported then they would have nice cool homes from the start. I don't know how to spread the word. Education in the world does a poor job in these areas and even when you have the education you are at the mercy of the sellers you encounter. The mass media does a poor job of educating in these areas also.

ECN: In PC World, you said, "It's like the way I used to make computers" -- how so? Also, are you hearing about any user groups for people who are building efficiency homes, a la the Homebrew Computer Club?

Woz: Simple design. Think about the right way to build something and take a lot of time to get it the best that can be done with the fewest resources used. No waste. Build it right and with few parts it does a lot. Don't cover things with more and more and more technology for features. Design them in from the start. It starts with the architect, of a home or a computer, working from a knowledge of the building materials and a desire to choose wisely.

ECN: Will you be using any other alternative energy sources, such as biofuels, solar cells, or wind power? Do you plan to sell any energy back to the local utility company?

Woz: I plan on a very low electricity bill that could justify solar cells. I worry that if it takes more energy to make and install a solar cell than it returns in its lifetime, then it's a loser. But you can't lose if it's a small addition to the home. I also may install AC/heating but hopefully never use it. I am deathly afraid of cold or hot homes but I'm willing to jump in the water and take my risks for something I believe in.

I may wind up buying some commercial solar cells with all the stuff to sell electricity back. But my electricity needs should be so small (clothes washer, lights, computers, TVs) that it may not amount to a significant amount.

ECN: Of the energy-saving techniques you will use, which are the most cost-effective or appeal to you the most? Are there any specific green technologies that you'd like to have today, but which aren't yet feasible?

Woz: I haven't analyzed if these Enertia Southern Yellow Pine woods are cost-effective. The total cost of the materials for a home seems reasonable to me but I'm not a builder. Once the home exists however, the energy savings and cost savings will come principally from the resin in the wood, but also from other carefully thought out aspects of the design. The designer is a civil engineering professor at BYU and cares a lot about saving the environment in every step of these homes, including how he makes the wood blocks for you.

ECN: Regarding the electronics that you anticipate using, do your concepts require any special advancements or new techniques? Or do you just plan to use existing systems in new ways?

Woz: I don't expect many changes. I want a large LCD TV and I use a laptop too. I buy energy efficent clothes washers and dryers at Sears too. As for house lights, I hope that LEDs make it further toward lighting normal homes by the time I build mine.

ECN: What are your plans for sharing the knowledge gained during the design, construction, and long-term living phases of this house? Maybe you could make a web page so others can learn from it.

Woz: Maybe. Not my first priority but it should be high. I expect accidental articles in papers and magazines featuring me because such happens a lot when reporters hear that I'm doing anything. [Editor's note: this article is a case in point!]

ECN: Do you envision the house as being just a cool hack that also helps the environment, or are you looking to invest in or even get personally involved with any startups for such technology?

Woz: Both. But I don't have a lot of investment money. I'm already on the advisory board for the ram-dirt startup I mentioned. It's called Integrity Block but is not off the ground yet.

ECN: What are you thoughts on balancing energy efficiency vs. overall environmental impact? Urethane-foam, for example, works well as an insulator but it takes oil and energy to produce and transport.

Woz: The total formula for saving energy can be quite deceptive. It's not correct to say that you are energy efficient when it's only in one way but your net is negative. For example, an electric car may use only half as much, or a third as much, energy as the same sized car using gasoline. But if it costs $100,000 then you realize that you wouldn't spend that much on gasoline over the life of any car. And even using the car uses some gasoline or coal used to create the electricity, to charge your batteries. If the car is inefficient in some ways it may even use more coal per mile but you'll be telling all your friends that it uses none. The cost of something is a reasonable estimate as to how many resources (of the Earth) you used to build the device. Don't take your instant opinion on energy efficient technologies to be correct. Ask a lot of deep questions and hold off until you are very sure

Hydrogen storage

It's open day at uni melb: I had a talk with a rogue 15-year
old about why hydrogen doesn't work yet.

Remember that, to produce the hydrogen needed by America's cars via electrolysis (splitting water with electricity) requires 8,000 TWh---twice the current total electrical throughput.

Well, the other problem is storage. Hydrogen carries a lot of energy per unit volume, since it is so light. But I think you can take it as impossible that the half-million dollar systems being used to store liquid hydrogen in today's experimental cars will ever go to market. Here's the volumetric and weight densities of hydrogen as a gas or liquid, and absorbed into a metal hydride. When they say 'minimum performance goal', they mean it: without a good storage system, a hydrogen fuel cell is essentially an inefficient battery. Pack your car with kilos of metal and it won't get far; it won't sell.


The real alternatives are the solid metal hydrides, metals which hydrize at certain temperatures and pressures. Magnesium Hydride, Mg H_2, stores the largest density of hydrogen but requires >300 C to let go of it

Again of the reversible hydrides simple magnesium does best. Magnesium is the world's third most abundant metal. Iron titanium comes next for price. Pretty much everything else is an exotic designer alloy as of now: tens of thousands of dollars per kilo.


Here you see the temperature at which the metal hydrides release the hydrogen at standard pressure. There's about a 30% penalty to heat the magnesium (30% of the fuel cell keeps the metal hot) but the same applies to liquid hydrogen. Plus you're driving the Hindenberg!

One possibility is alloying Lanthanum (a room temperature hydrilizer, but energetically poor) with the hot metal magnesium. But still---you look at the above graph and its basically a line, either you get density or temperature. It would nevertheless be possible to build a heat battery from Magnesium, and it sometimes wonder if it might beat big flywheels as energy storage.

We're building just massive flywheels at the moment to convet electricity into kinetic energy and back. They're run on superconducting bearings. But another time...

Democrats = Enviornmental R&D

US Congress' climate to spend

Richard Simon, Washington
August 22, 2007

REFLECTING a shift in priorities under the Democratic majority, US Congress is moving to spend as much as $US6.7 billion ($A8.4 billion) next financial year to combat global warming, an increase of nearly one-third from this year.

House appropriations bills call for about $US2 billion in new spending on initiatives aimed at reducing greenhouse gas emissions and oil dependency, significantly expanding the budgets for new and existing research initiatives.

While legislation to raise car fuel efficiency standards and cap emissions from power plants has been slower-moving — because of resistance from some members of Congress — Democrats have turned to the budget to advance their environmental priorities by increasing spending on lower-profile programs.

But that will probably set up a showdown between Congress and President George Bush, who wants to spend less on climate change initiatives.

The White House budget office, which has complained about excessive spending in the overall appropriations bills, noted that Mr Bush's budget provided for a 3 per cent increase in spending for climate change activities.

Members of Congress from both parties also see the public's heightened interest in climate change and energy security as an opportunity to steer federal money to their states.

Money has been set aside for scores of home-state research initiatives and construction projects.
"Green is becoming very fashionable," said a Republican congressman from Ohio, David Hobson, who secured $US500,000 for a geothermal demonstration project at Ohio Wesleyan University.
"I think members are going to be challenged in their district," he said, referring to how they respond to concerns about climate change and US dependence on foreign oil.

Adam Schiff, a California Democrat, got $US500,000 for a fuel-cell project by Superprotonic, a Pasadena company started by California Institute of Technology scientists.

"America needs to wean itself off of foreign oil," Mr Schiff said in a statement. "This is as much a national security imperative as it is an environmental one. And federal support for innovative new technologies is part of the answer."

Some of the largest increases are in the bill that funds the Department of Energy.

The House provided about $US1.9 billion for energy efficiency and renewable energy programs, about 52 per cent more than the Administration requested.

Just two years ago, under the Republican-controlled Congress, the programs received about $US1.2 billion. The Senate has yet to complete its spending bills, but its appropriations committee has recommended about $US1.7 billion for energy efficiency and renewable energy programs.

Environmentalists welcome the increased spending but say more pollution regulation is crucial.
"Those spending measures are no substitute for better fuel economy standards and tough caps on greenhouse gas emissions," said Frank O'Donnell of Clean Air Watch.

Some of the projects are the result of unusual alliances between members looking out for home-state interests and those seeking to reduce pollution. Those in coal-producing areas have been among the strongest supporters of increased funding for projects to capture carbon dioxide from coal-fired power plants, seeing it as a way to preserve the coal industry.

Critics say some projects may be worthy, including energy research initiatives, but others are merely classic pork-barrel spending, particularly construction projects that have been touted to Congress as green.

Jatropha breeding

8 Breeding
Breeding objectives
Breeding objectives will depend on use. Oil yield will, in most cases, be the most important
part of physic nut cultivation. Components that contribute to physic nut oil yield
per hectare are: number of pistillate flowers per inflorescence and subsequent number
of capsules per shrub, number of seeds per capsule, 1000-seed weight, oil content of
seeds (%) and plants per hectare. As the maximum number of seeds per capsule is
limited and the agronomic factor of planting density does not offer much flexibility for
increasing yields, selection should focus on the other yield components.
Ferrao and Ferrao (1984), and later Heller (1992), found highly significant correlations
in different seed samples between the 1000-seed weight and percent of crude fat
content. This might be interesting from the breeders’ point of view, as simple selection
for high 1000-seed weight could imply increased crude fat contents. From this, it cannot
be concluded that shrubs which produce seeds of a high 1000-seed weight, and consequently
a higher crude fat content, will yield more oil per hectare. A high 1000-seed
weight can also be the consequence of a low seed yield per shrub. Further research on
this is required.
Other important objectives are reduced plant height to facilitate harvesting of capsules
and development of non toxic cultivars, where the seed cake could be used as
fodder.

D1 Oils is taking the leading role in cultivating non-edible oils for biodiesel. They're planning on Jatropha, which has a higher yeild than Pongamia or moringa, but is lethally poisonous to both people and animals (limiting the use of byproducts as fertilizer or animal feedstocks---but requiring no pesticides).

Importantly, D1 is working with universities in the Netherlands to improve the yeild of Jatropa lines. None of the non-edible oil stocks have ever gone through any selective breeding, and they display a range of 20-40% in the amount of oil contained in their seeds. A program for breeding these plants would probably win a grant pretty much anywhere.

It's unclear to me why development is being limited to Africa and India; presumably land values are too high in Australia. It's also possible that, even for this low-water species, Australia is too dry.

Anyway they're investing >$100M in this and are developing the kind of huge chunks of land that people have always thrown about as being concievable:

The figures for land contracts are either fake or revolutionary: even at a conservative 500 litres oil/hectare the 70,000 hectares contracted here would replace 70% of the UK's yearly oil consumption.

There are also a few 'hippy' projects, such as one run by the Himalayan Institute. Neodyne is an Indian company that's planning the growth of pongamia, particularly for the direct use of seed oils in diesel engines to promote village economies.

D1 doesn't look like a hippy project and it ain't aiming for villages. It looks like big business, the kind of entrepreneurship that high oil prices (and taxes, and an economy that has so disconnected itself from industry that it can grow independant of oil consumption) lead to.

An idle question:
Australia has a helluva lot of undeveloped land, used for low-density sheepherding because there's no water. A lot of farms were started in the early 1900s as the aussies pushed into the center of the country, which failed to be viable.
But, are there any crops that would be happy to grow on dry land, be resistant to drought, and would provide a biofuel? The key here is that Australia is in a unique position of being a first-world nation, with quick development times, but is located on terrible and valueless soil.
Answer?
RESEARCH INTO THE PRODUCTION OF BIO-DIESEL FROM PERENNIALS
A scoping study funded through South West Catchment Council (SWCC)/NationalAction Plan (NAP) into the development of industries for saline land, identified threeplant species suitable and potentially economically feasible for this environment. Themain product of two of these plant species, is the production of bio-diesel. Thementioned plant species are Moringa oleifera and Pongamia pinnata. Both are tolerant to high salinity levels, waterlogging, frost and drought. Their pods are harvested, meaning that the trees keep on growing, using water and reducing the high watertable whilst sequestrating carbon.
Bio-fuels must be sustainably, with these two plant species fitting all the criteria.
It is salt tolerant:Land salinasation is one of the greatest challenges to landproductivity and water resource management in the SW Agricultural region withdryland salinity affecting 30 per cent of the SW Agricultural Region in WesternAustralia (1 million hectares) or at risk of being affected in the future.
It can grow on marginal land: Traditional cropping of marginal land combined withcontinuous rising input costs is not economically viable. Land has to be farmedaccording to its capacity.
It sequester carbon and reduce greenhouse gasses: Climate change and greenhousegas emissions are becoming more important by the day. Addressing these issues aspart of every farming system is crucial, not only for the environment but also formarket access and premium prices.
It is an ethical land use: Utilising crops suitable for human consumption or landtraditionally producing grain for bio-fuel production is contentious, however thesetrees can be grown on marginal land. Supply and demand factors and energy balancemake other bio-fuels less of an option but the energy balance is positive for thesetrees and it does not compete with traditional food for human consumpton.Although the ideal climatic conditions for these plants are dry-temperate, they do grow in Mediterranean climates with not much known about yields in this environment. Because none of these plants is grown on a commercial scale in Australia, international data on yields was used for an analysis, which produced promising results in terms of profitability. These data suggests that:
Pongamia pinnata produce 2,000 – 4,000 litre bio-diesel per ha per year.Production starts from year 4 onwards. The oilcake is used for fertiliser andcontains a natural insecticide. Water requirements under rain-fed conditions are500mm plus and internal rate of return calculated at 47 per cent (non-irrigated).
Moringa oleifera produce 1,000 to 2,000 litres bio-diesel per ha year. Productionstarts within a year and the oil cake and leaves are excellent stock feed. Minimumwater requirements under rain-fed start at 250mm whilst the internal rate of returnwas calculated at 84 per cent (non-irrigated).
>>>>1000 litres per hectare is astounding. For comparison:

Ethanol, a biofuel fermented from grains or sugars, can be combined in a 10% mixture (E10) with ordinary gasoline without any modification to the car's engine.
Here in Australia, ethanol is being produced from sorghum (a relative to maize, which can be harvested multiple times during the year and requires only 1/3rd the water of sugarcane) and a 2% mixture (E2) with gasoline is being mandated in New South Wales, where the largest plants are located.
The Howard gov't has recently guaranteed that biofuels will be untaxed until 2011, with a slow ramp-up afterward. However, the Howard gov't refuses to mandate E10 usage countrywide. Australia plans to produce 350 ML of biofuels by 2010 (10% of the fuel needed for a full gas-to-E10 conversion).
Ethanol use in a gasoline mix, or in a 'flex-fuel' engine designed to handle either gas or pure ethanol, reduces the amount of greenhouse gas emissions only slightly, while it increases the amount of smog-producing nitrous oxides. It must compete not only with the price of oil but the exchange rate with the US (remember, OPEC only accepts dollars). In order for ethanol to be cheaper than gas oil must be at $65/barrel and the aussie dollar at <$0.65 (US). Today it's $73 and $0.85. Also, there is some controversy that more energy is used to produce a liter of ethanol with grain-stock than is contained in the ethanol (the estimate is now around 120% but this has a lot of fudge factors, see below)
FeedstockEnergy output/fossil energy inputSugarcane8.3Sugar Beet (European Union)1.9Maize (United States)1.3-1.8Wheat (Canada)1.20Switch grass4.4Fossil fuel (Gasoline)0.8Sweet sorghum (Hosein Shapouri, USDA)8.0 (12-16 in temperate areas)
Local ethanol production does inject money into the Australian economy. A speculative boom in the price of raw sugar in mid-2006 was brought about by the addition of an ethanol market, and prices for land in wheat- and corn- producing states has grown on the back of green speculation.

Australia’s first ethanol plant begins site preparation
Bulldozers started preparing road access and a railroad crossing in December at Australia’s long-awaited ethanol plant near Dalby, Queensland. Dirt work was expected to start in late January with mechanical construction starting shortly thereafter, according to Chris Harrison, director of Dalby Bio-Refinery Ltd. Harrison, who has more than 25 years experience as an independent fuel and lubricant distributor, has championed the Dalby project since 2002. Initially scheduled for construction in 2003, two issues delayed the project. “Excise has been resolved, with a zero excise until 2011 and then a phase-in of 2.5 cents per liter (cpl) until 2015 when the final excise applicable to ethanol of 12.5 cpl will apply,” Harrison said. The project also had to fight for support from Australia’s major oil companies and consumers. Dalby Bio-Refinery won the fight with “time and perseverance,” according to Harrison. “The major oil companies in Australia are now demonstrating a commitment to achieving the federal government biofuel target by 2010, and consumer confidence is improving daily,” he said. The US$75 million ethanol plant will employ 30 people and produce 80 mmly of ethanol (21 MMgy) from sorghum. It will also produce around 170,000 tons of distillers dried grains with solubles. Delta-T provided the plant design, and Leighton Construction is handling the construction.

From Calgary HeraldOzzie Durock
Environment trend has green cash potential
Note: Real estate expert Ozzie Jurock is to be a speaker for the real estate section of the InvestFest conference, which is to be held on June 8 to 11 at the Fairmont Palliser Hotel in Calgary.
"According to a new U.N. report, the global warming outlook is much worse than originally predicted. Which is pretty bad when they originally predicted it would destroy the planet." Jay Leno
Green. The term is everywhere these days.
Climate change and global warming have become the new doomsday clock, the new cold war, the new Y2K of our collective what-if nightmares.
Attempts to inject rational thought into the zealous belief that human activity will cause seas to rise, crops to fail and hurricanes to whirl is being drowned out in an amazingly on-script media and public chorus.
Yet, according to the Intergovernmental Panel on Climate Change, the international august body which recently released its definitive report, if the entire world accepted the complete Kyoto protocol (which commits to reduce carbon emissions by five per cent from 1990 levels by 2012) tomorrow, there would be no noticeable change in the planet's climate for 80 years -- at a cost of five Iraq wars per year.
To put it another way, if Canada immediately stopped producing any form of greenhouse gas emissions, it would take only 18 months for that to be replaced by China's growth in emissions.
Sorry, your new Hybrid will not make much of a difference in the big global picture.
We agree with the premise behind climate change, but we also agree with the findings of the experts that nothing we do in our lifetime in Canada will make any difference, and it is not likely it will change the weather for our children, or even our grandchildren.
It reminds me again of the old adage: "Forecasting is never easy, particularly when it is about the future."
But the American government currently spends 51 cents US per gallon to oil companies to produce ethanol, plus a thousand other incentives and that lead us to believe that we should be buying farmland in Saskatchewan, for example.
The U.S. government also gives some $6.5 billion in grants to the "green research" industry.
All that momentum -- valid or not -- will accelerate the train towards more greening. Most importantly, the reality is that the Canadian public, especially in B.C. and Alberta, are solidly behind the climate change philosophy and most (at least 80 per cent according to a recent poll) want to personally do something about it.
With that kind of support, green is a force to be reckoned with in the real estate industry and it would be a fool who would ignore the challenges and opportunities it represents (certainly -- we hasten to add -- in my own home, we recycle religiously, eat organic, use biodegradable cleaners and soaps, and we look continuously for ways to be become more and more aware.)
The green real estate effect is already having an impact on everything from house sales to farmland, from condominiums to waterfront.
We have seen some very interesting real estate reactions to the green philosophy, some of which were overdue and make good economic sense.
Consider Avalon Homes of Red Deer.
Five years ago, as a newcomer to the booming Alberta new home market, Avalon was struggling to make its first sales and find a niche in the competitive market.
Then it began marketing itself as the "green builder," constructing homes that are a notch above others in Alberta's popular Built Green program founded in Calgary.
Today, Avalon is among a dozen builders across Canada -- and three in Alberta -- chosen by the federal government this February as the top environmentally conscious in the country.
Last year, Avalon sold 200 new houses, making it the number one builder in Red Deer despite charging more than its competitors.
It expects to top that sales pace this year. Its prototype house has solar panels on the roof, thick insulation and other green attributes that make it a "zero net energy" house, meaning it can actually produce as much energy as it uses.
Chard Developments in Victoria is another example.
In the midst of a slowing new condo market in Victoria, which saw 3,100 new condos started last year alone, Chard presented a "green twist."
In its pre-sales for its 15-storey Juliet tower now being built on Johnson Street, Chard offered to cut $25,000 off the price if the buyers would forego an underground parking space for a bicycle locker and a deal to join in a local car share program, where Chard would pay their initial membership fee.
It worked. The lower cost suites -- in a building with an average per-square-foot price of $500 -- sold first and fastest, the project received positive press as a green project and Chard could spend less on the parking space.
In Vancouver, developer Aragon Properties Ltd. is marketing a townhouse project that it built on spec on a former industrial site in one of the less-than desirable neighbourhoods of Marpole.
But, by an intelligent blend of fairly low-cost green features, its Moda project has proved a hit with the upscale, yuppie clients it was aimed at.
The green attributes include recycled brick for interior walls, reclaimed wood for the hardwood floors and individual gas meters allowing residents to monitor and control individual gas use, plus Energy Star washers and dryers.
Not a lot of green, really, but enough to notch Moda successfully into the "green marketing" environment.
Of course, the green marketing can stretch credulity a bit.
In Ucluelet, where legendary golfer Jack Nicklaus is backing the new Wyndansea Oceanfront Golf Resort, developers have recruited the Audubon Society, a non-profit environmental organization, as overseers on the project.
The entire project, which will cover hundreds of hectares along the Pacific Coast, will also be built to the Leadership in Energy and Environmental Design (LEED) Gold standards.
It turns out, incidentally, that the Audubon Society is overseeing 27,600 hectares of "sustainable" golf courses around the world (only a cynic would question that if the developers are so concerned with the environment, why they didn't just leave the pristine waterfront alone.)
Nicklaus and co-developer Marine Drive Properties recognize that green sells.
We share their confidence that the golfside residential lots, expected to start in the half-a-million dollar range, will sell out, and probably quickly.
For there is no overestimating the green demand side.
Fully two-thirds of Canadian consumers would switch their spending to companies that have demonstrated a commitment to green policies according to a survey done last month by Environics Research Group.
The poll found that 67 per cent said they are likely to switch to green businesses.
In British Columbia and Alberta, consumers are most likely to make the switch, with 83 per cent saying they would, even it meant paying a higher price.
"We're seeing a fundamental shift in consumer behavior that reflects the increased mainstreaming of environmental consciousness," says Michael Adams, founding president of Environics. "Canadians are very deliberately rewarding those companies who are taking action on the environment."
The flip side message: consumers will punish those who don't make environmental improvements.
So as a real estate investor, what does this mean to you?
As with any investment opportunity, there are many in the green area. When we can do our homework and find bargains and growth opportunities before the general market recognizes them, it is always a good thing.
First of all, buy into green buildings.
The ones built to green standards are usually built better and tend to retain tenants longer and command higher rents.
Buy into green condominium projects because they attract the kind of upscale, higher-income consumers you want to be associated with.
Ditto for commercial buildings.
Studies, such as Green Building Costs and the Financial Benefits (done for the Massachusetts Institute of Technology in 2003) show that while incorporating basic green features to a building can add less than one per cent to the overall cost, tenants are willing to pay higher lease rates, tend to stay in place longer, and the owners enjoy lower maintenance and energy costs.
"It used to be risky to go green," says Gregory Kats, managing principal of Capital E Group and former director of financing for energy efficiency and renewable energy at the U.S. Department of Energy.
"Now, it's clear, it's more risky to design inefficient and unhealthy buildings. It's bad management and bad investment strategy to not build green buildings."
Mark Palmer, San Francisco's green building co-ordinator, notes: "In a study of 33 buildings nationally (in the U.S,) the average added cost for building green was less than two per cent and the return was 10 times the investment over a 20-year period."
We would also advise investors to still look at waterfront real estate.
We know, we have seen the scary headlines and seen the Al Gore clip of New York and Florida disappearing beneath the waves.
Yet, according to the best and latest information and projections from the Intergovernmental Panel on Climate Change, worldwide sea levels may rise about 41 centimetres (16 inches) in 100 years.
If your oceanfront property is a yard above the water, you should be OK. Of course, lakefront would likely not be affected at all.
Buy farmland on the prairies. In Idaho and Iowa -- major producers of crops used for ethanol production, considered a greener fuel additive, farmland values have shot up as much as 20 per cent in the past year to $5,000 US per acre.
In Saskatchewan, where three ethanol plants are operating and a big one is about to open near the U.S. border at Belle Plaine, croplands average $350 per acre.

Hmm, well this couple is claiming a 2x return on investmentGoing 'green' at homeA Seal Beach couple try to flip houses they have made environmentally friendly.By SCOTT MARTINDALETHE ORANGE COUNTY REGISTER
ROSSMOOR – These days, it's not uncommon to flip a house – buy a property, renovate it and quickly sell it – but Drew and Carolyn Wesling have come up with their own niche in this business, one that's friendlier to the environment.
The Seal Beach couple are going into business making older homes "green," hoping an environmentally conscious approach to homebuilding will translate into profit. Their first property, a $1.75 million Rossmoor home they bought two years ago for $800,000, is now on the market.
"These are just little things that can be done to help the environment," Drew Wesling, 35, a construction project manager and an accredited green professional. "This isn't cutting-edge stuff. It certainly didn't take any extra money."
The 3,500-square-foot home, which doesn't look all that different from any other house, includes energy-efficient windows, a "tankless" water heater, bamboo wood floors and a variety of environmentally friendly building materials.
When the Weslings bought the home in November 2005, it was a 1950s-style original Rossmoor tract home with three bedrooms. They gutted much of the one-story house and added a second story, two bedrooms, a family room and a breakfast nook, more than doubling its size.
Their "green" remodel is part of a nationwide trend toward adding more environmentally conscious features to homes, schools, libraries and commercial buildings, experts say.
Within a few years, building green could become as well-known as the Energy Star ratings on appliances like refrigerators, said Walker Wells, program director for Global Green, a Santa Monica-based nonprofit that promotes green building.
"If they can demonstrate to other builders that going green is a way to make money, that's phenomenal because hopefully other people will embrace it, too," Wells said.
The couple, however, aren't applying to have their home certified green by the U.S. Green Building Council. The guidelines are too strict, and certification would be too costly for a single house, they said.
Q. How did you get interested in building environmentally friendly houses?
Drew: I was exposed to green building in 2001 on a project in Santa Monica. It was an office building for the Natural Resources Defense Council, an environmental advocacy group. I loved that project, so I got involved in the U.S. Green Building Council and joined the board in Los Angeles.
Q. Your house looks brand new, but you actually renovated the original house. Why did you remodel instead of leveling it?
Drew: It's so much to easier to tear down the house, but you don't want to send all of that waste to the landfill.
Q. Do you live in a green house now?
Carolyn: No, we're renting in Seal Beach. We're looking for two lots in Rossmoor, one for us and one to sell. As soon as we're in escrow with this house, we'll move forward. I'm hoping as we move forward, they're going to get greener.
Q. You've had to move around a lot. You spent a year in your Rossmoor home, then decided to remodel it. When you build your next home, you'll have to move again. How do you cope?
Carolyn: We have a high tolerance for construction. I definitely feel like I've gone back to work, but I have control over what I'm doing, and the second income will be so nice.
Q. How did you convince your kids to let you sell the Rossmoor house?
Drew:They love the h

I should add a second extrapolation to the one regarding the middle class and renewables:
It is the middle class which suffered most from the OPEC-related gas price crisis of 1973. At that time, inflation and the price of oil were inextricably linked, and the middle class was hit with a period of high unemployment and high inflation. The 1990's period of previously unheard-of low unemployment and inflation was probably linked to $10/barrel oil, as much as the technology bubble.
The upper class loves expensive oil, with oil companies taking in huge profits. And as we've seen today, the stock exchange can do very well with $70/barrel crude. It's the middle class which suffers at the pump, and the middle class that's hurt by unemployment. It's also the middle class which would most benefit from efficienct cars and homes. That's why I think gov't policy should be centered on home improvements below $10k. And it's why I think energy policy belongs uniquely on the Democratic platform, is something to be capitalize on.
Incidentally, the 1973 crisis was linked to the 1971 removal of the gold standard: with dollars no longer anchored to $35/ounce of gold, a floating dollar was set for problems. Incredibly, OPEC decided to accept only American dollars as payment--a policy which continues today---meaning that instead of the Sterling's power based on the stock of gold England held through its empire, the American dollar became the standard world currency on the back of Middle East oil. The American dollar is backed not by gold but by Saudi oil. That's why there's a connection between inflation and the price of gas. And it's why we cannot allow anti-American monarchies to thrive there.
And this leads me to my second extrapolation:
The capital investment required to make America independant from OPEC oil (I'll assume we're still happy to take the 135 billion barrels of bitumen stuck in Canadian oil sands---Canada is the largest foreign exporter of oil to the US, it's just that the Saudis have the largest *reserve* stock, they're the only ones who can turn up the taps, so they control world prices) the captial required is only available through a massive government-sponsored, R&D led investment. Something over a trillion dollars in a twenty-year period.
And the only reason the government will MAKE that investment is if it becomes clear to them that our national security is, today, more tied up in energy than in bombs. I think the example of Russia is instructive here, and the clarity with which Putin sees his reserves in the Caspian as more important to Russia's place in world politics today than its ability to blow up the planet.
I remember a talk I had at a lunch table at Los Alamos. It was my claim that energy was a larger national security issue than nukes, and that we needed a Los Alamos project targeted at new technologies to reduce our reliance on foreign oil.
Today I believe something a little different:
Los Alamos was founded in the 30s and we had a world-changing (and war-ending) new technology 15 years later. No such technology exists to solve the energy problem. What is instead required is a massive investment in infrastructure and existing (but immature) technologies which haven't been developed by the private sector in the years following the 1973 crisis. We require stricter building codes and higher CAFE standards.
And the frame for this debate cannot be global warming.
Incidentally, ever wonder why global warming gets more press in the UK? It's because the growth of the UK economy is unlinked to a growth in oil consumption. To grow our own GDP we *require* more oil, although this link has become weaker in the post-industrializing period since the 1970s. The GDP/oil growth ratio in China and India is the same as it was in the US from 1940-70, reflecting their rapid industrialization.
Global warming isn't going to cut any ice in the US, not on the trillion-dollar levels required. But energy security can. If another price shock occurs (e.g. a supertanker blown up, moves from the Caspian toward China, etc.) , up to $5 or so, it may be possible to convince the government to make investments on a par with the US Military.
So strategy one is hippy houses ('enabled' houses maybe). Strategy two is a new energy complex. And overriding is a political strategy of putting enviornmentalism (NEW enviornmentalism, attached to warming and security as opposed to the land-use issues of the past) to the fore of the Democratic party.

Flipping Green Houses

I've been reading thru the stuff put out by the International Energy Agency in cooperation with the G8 meetings. Interestingly, they project that the same amount of carbon might be saved (by 2050) via efficiency improvements in the home, as by changes in transportation.
And that's assuming hydrogen is up to 10% of transport energy by 2030--far from assured. It also assumes electric hybrids are adopted far more than today.
The point is, efficiency in the home is just as important to carbon savings as efficiency at the pump. The methods are cheaper and more DIY, and are amortized in a home which will stand for >20 years (the average life of a car in the US is 7 years). Here's how the improvements break down:
The IEA projects a large amount of savings through insulation and heat pumps. They claim that 37% of energy used in a home is for heating, and that proper insulation and the use of heat pumps can reduce this by 75%. Their projected cost for such improvements over 20 years is 1-2 cents per kWh saved.
The heat pump comes with a $500 or 10% federal tax incentive and $200 from energySTAR incentives in Oregon. The same incentive project gives roughly $0.30/sq foot back for improved insulation. These lower the capital cost to $3500-550=$2950 for the heat pump and $2000-1500 =$500 for the insulation. Orgeon's credit for insulation is absolutely insane: they pay around 80% of the materials cost. Everybody should be doing it.
At a $20 mortgage value increase per dollar energy saved these improvements are worth (in principle) around $9000.
19% of the energy used in a home is for lighting. Here they suggest the obvious, which is higher-efficiency bulbs.
For both of the above the IEA also discusses the possibility of central computer control of lighting, heating, security, and safety (i.e. fire detectors et al.). The only method of controlling heat today is the thermostat, but as I flip through catalogues I reckon I could put one together for the low thousands---essentially a PDA programmed to talk to USB-enabled power outlets (also here) and web-enabled thermostat connected to room temperature detectors and enabled air vents.
The PDA (probably running the open Symbian OS) would give you independant control of each room's temperature, together with lighting. In the process of a retrofit one could easily make a home 'enabled' by running USB and hi-def video output thru the walls to a central computer (e.g. a media center with a very large hard drive for DVD storage). Any room of the house could hook up to the television/movies/internet just by plugging a keyboard and tv into the wall. The central computer would also track smoke alarms that never run out of batteries (and perhaps a security system?)
The web-enabled thermostat runs you $200 and hdmi/usb enabled wall plates run around $50 each. Cable installation would presumably take place during the larger retrofit and might run in the low hundreds. A new computer (no monitor) would run around $1500. I feel like this would be a large value-adding geegaw that might be worth $6000 to the prospective buyer. Could pop in speakers to the rooms as well.
8% of future improvements in home efficiency will come from newer appliances (i.e. other than air conditioners). In most cases, though, the cost savings in a new appliance does not excuse replacing the old one. There are small incentives in Oregon for new dishwasers, fridges, or washing machines of around $80-$200.
Finally there is solar water heating, which is very much DIY. Active solar air heating is still about 3-5 times more expensive than traditional heat/air and won't be commercial for decades. A DIY flat-plate water heater runs around $700 before $200 in incentives and pays back immediately.
So here's the picture:
Year one, I live as cheaply as possible, in Oregon, working both as a teacher and as a renewable energy salesman.Year two, I buy a home with a mid-term mortgage. I dump around $8k into home improvements, including (but not limited to) efficiency improvements.Year three, I sell the home and move on with pocketed money and experience.
The home improvements start with better insulation and windows, together with a new heat pump. Together these run $5500, $2500 of which is paid back to me. The improvements should add $8000 in value to the house.
They continue with a solar water heater, which will cost $700, $150 of which will be paid back. It adds $1000 to the value of the house.
Next in line is computer control, of my own design. This aspect may have its own commercial application. The cost is $2500 and I estimate its worth is at least $5000.
Finally I install efficient lighting and appliances. Also, stuff which may be of value: a deck, or flooring, or a new kitchen. An 'arizona' room adds sq ft to a house which generally exceeds the required investment. These soak up the remainder of my $10k investment.
I then hope to sell the house for (at least) $20k more than I bought it for.

Renewable Hydrogen?

Crunching some numbers on the use of renewables for hydrolysis:

One kilo of hydrogen gas is energetically equivalent to one gallon of gasoline. Granted, a fuel cell or internal combustion engine running hydrogen is a little more efficient than gas, but the energy lost from storing the hydrogen (as a liquid, or in a metal hydride--see next post) more than makes up for this. Anyway 1 kg H_2/gallon gas is convenient.

The hydrolysis process to produce that kg of hydrogen requires about 65 kWh of electricity (practically) though this could be lowered to 40 kWh in the mid-term future. Everything involving hydrogen or renewables takes a 20-year window or so.

In 2005 the US consumed 140 billion gallons of gas. So to replace gasoline with hydrogen would require 8,000 terawatt-hours of electricity, roughly one-and-a-half times the throughput of the current electrical system. Doing so without carbons would require the construction of something like 1000 nuclear power plants.

The US is currently planning three new plants and they're being fought like hell.
The present price of electricity in the US averages (in 2004) about 7 cents per kWh commercially, 5 cents industrially. At these prices a kg of h_2 would cost around $5: perhaps lower if the utility itself got involved in the hydrogen business.

Let's set our sights on electrolysis via solar energy provided by stirling engines. According to Sterling Energy Systems (SES), their 150 kW units currently cost $150,000, 25% of which cost is the solar dish. So the engine itself, provided by a german company who manufactures them for use in ultra-silent submarines, costs over $100k. SES claims that they can reduce the cost, once mass-production is set up, to $50k a unit.

We'll put our generators in the Mojave desert, as SES has, where an average of 6000 Watt-hours per day is produced, implying around 7 hours per day (on average) that the engines will run. So the cost per kWh (using the optimistic engine cost of $50k) over 5 years is a shade over 3 cents, implying a hydrogen cost of $3.50/kg.

Over 10 years, and let's include the cost of keeping the engines running etc, this goes down to maybe $2.50. Are industries willing to sink huge capital into projects that will only turn a profit after ten years (if then)? I dunno.

Here is the breakdown of the cost of a gallon of gas in 2007:
Distribution
Costs, Marketing Costs and Profits $0.20
Crude Oil Cost $1.72
Refinery Cost and Profits $0.63
State Underground Storage Tank Fee $0.01
State and Local Sales Tax $0.23
State Excise Tax $0.18
Federal Excise Tax $0.18
Retail prices $3.16

So we're competing with the crude + refinement cost of $2.30. Even in the best case renewable hydrolysis only competes with $5/gallon oil, or $100 a barrel sweet crude. I don't see that happening anytime in the next 50 years (It's at $73 now).

So far the scheme appears to be possible if unlikely. But now look that the investment required:
Let's take our goal as producing 10% of the 8,000 TWh renewably, and have a look at the SES plant in Mojave:

This plant is composed of some 3,000 individual generators and is projected to go online in 2009. Using SES's numbers (the big one, $150k/generator) I'd guess it'll cost about half a billion dollars.

For 800 TWh you'd need around 1000 such plants at a cost of half a trillion dollars, just to provide the power. Best case, to provide 10% of America's gasoline requirements renewably you'd need around a trillion dollars. That's maybe not excessive in light of the e.g. 70 billion being invested to extract canada's oil sands, but then that's coming from big oil. Who's investing in hydrogen?

All my numbers here have been incredibly idealized, using stirling power as a magic bullet--far superior to photovoltaics--and remember they only seek to supplement transportation by 10%. Conclusion? Gasoline can't be replaced renewably at anything like our current usage levels. And remember that if you're making hydrogen from something other than nuclear power, you're just replacing the delivery system: oil still needs to go into producing electricity (or perhaps coal, but this is dirty, or natural gas, but the US hasn't invested heavily in that).

Extrapolation? Renewables need to be targeted to middle-class families feeling the pinch of increased energy prices. This area (<$10k) takes maximum advantage of government aid and capitalizes on public opinion. But it can't help in the long haul.

A New Cold War

I entirely agree with this guy's assesment that greentech *now* shapes geopolitics, but I disagree that the solution of a technological problem will come from politics. Technological solutions come from science.
As far as I can tell, there is no book that addresses what technological issues need to be addressed. I mean, suppose the US starts a new 'apollo' project with greentech as its research goal. What technologies, exactly, would such an institution study?
Energy: the new cold war
Liam Fox
Since the close of the cold war, we have been growing used to threats such as terrorism where the enemy has no state or territory. But soon we will have to get used to new strategic challenges, such as energy security, where fossil fuels will be used as weapons to achieve political ends. Energy security will be synonymous with national security and economic security.
Two weeks ago Russia announced its intention to annex a 460,000-square mile portion of ice-covered Arctic. Scientists claim that the area, on which Russia has audaciously set its sights, may contain an estimated 10 billion tonnes of gas and oil deposits. While this ridiculous claim has no legitimate legal basis, the West must take threats like this from Russia seriously.
Russia is rivalling Saudi Arabia as the world’s largest oil producer and is estimated to have the world’s largest natural gas supplies with 1,680 trillion cubic feet - nearly twice the reserves in the next largest country, Iran. If military might and nuclear weapons formed the core of Soviet cold war power, Russian elites view its energy resources as the basis of its power now.
Russia has demonstrated that it will use its energy resources to promote a broader foreign policy agenda. This was illustrated when Russia reduced gas supplies to the Ukraine as part of a bilateral dispute and when it doubled the price of gas to Georgia in 2005.
Russia’s petrodollars are financing a $189 billion overhaul of its armed forces between now and 2015. They will purchase more than 1,000 new aircraft and helicopters, 4,000 new tanks and armoured vehicles and a new submarine fleet. New missiles will carry nuclear warheads. Western addiction to oil and gas is causing us to fund the threat against us.
Reports that Russia is now withdrawing from the Conventional Forces in Europe Treaty will only fuel suspicions about Putin’s defence posture.
The stand-off over Litvinenko is another source of tension.
Unfortunately, the threats do not stop with Russia. Terrorism poses a major threat to world energy supplies, transport and infrastructure especially. Osama Bin Laden has described refineries as the “hinges” of the world’s economy. Al-Qaeda’s failed attack last year on the Abqaiq oil facility in Saudi Arabia is a reminder of the threat.
Future attacks could disrupt the world economy far more. An assault on a super-tanker in the Straits of Malacca could send the oil price rocketing, and tip economies which have just about coped with higher oil prices over the edge. If Japan’s maritime supplies of crude oil were choked, even temporarily, a crisis of confidence could reverberate around the world. For developing countries, a sudden rise in fuel prices could wipe out the benefits of aid or debt relief. Fuel poverty would be a brutal reality.
Fear of terrorism is justified. In 2002, Al-Qaeda terrorists rammed a boat rigged with explosives into a French tanker off Yemen but fortunately it did not sink.
The distribution of global energy supplies means we are particularly vulnerable to the “choke points” in transport routes around the globe. These are far more numerous than the days when we simply patrolled the Strait of Hormuz. They are scattered from the Panama Canal to the entrance to the Red Sea to the seas of southeast Asia. So what can be done to ensure the security of energy resources, including the refining and transport of such resources?
The EU has an important role to play, especially in countering the difficulties posed by Russia. An end needs to be brought to the divide and rule which the Kremlin operates through single nation “sweetheart deals”. The commission must act to remove protectionism and national monopolies, creating a genuine free market in energy. Better interconnections will reduce the risk of supplies being cut off to those who displease the Kremlin.
But the EU will not be a sufficiently strong vehicle. Nato must play a key role in ensuring energy security for the West. The EU lacks the military capability and the political will to undertake any ambitious energy security agenda. Politically the EU’s hand is weak against Russia, militarily it is even weaker. Jose Socrates, Portugal’s prime minister and current EU president, recently made it very clear that he would avoid confronting Russia.
Norway and Turkey, both of which are valuable Nato members, are not members of the European Union. No energy security strategy can work without the support and cooperation of these two states. Both played a vital role in Nato during the cold war by being the only Nato members that bordered the Soviet Union. After the cold war their geo-strategic importance is just as valid. In the south, Turkey is the gateway to the resource-rich Caucasus and Caspian Basin. In the north, Norway is located near the resource-rich Arctic Ocean. Giving a greater role in energy security to Nato will provide added prestige to Turkey and allow reformers a breathing space given the shortsighted attitude taken to EU membership by some prominent members.
The complexity of energy security makes it too easy to look the other way and hope that someone else deals with the problems. Dealing with energy security issues will involve the protection of maritime supplies and pipelines. New international arrangements will be required to safeguard supply in an interdependent global economy with shared risks.
Nato is a logical partner in such a project, possessing both military and political strengths. The threat is real and the implications are great.

Future Energy That Generates Profits Today
By CONRAD DE AENLLE
Published: July 21, 2007
ALTERNATIVE energy is considered to be good for the environment and good for the soul, but not so good as a way to make money. Generating power from renewable sources like wind, the sun and the earth’s own heat has a reputation for being unprofitable without government subsidies or sky-high energy prices.

The Energy Challenge
A series examining the ways in which the world is, and is not, moving toward a more energy-efficient, environmentally benign future.
But for shareholders of a specialist mutual fund, it has been an easy way to generate smart returns. Guinness Atkinson Alternative Energy has returned close to 40 percent so far this year, better than all conventional energy funds in the database of the research firm Morningstar.
The rising cost of fossil fuels undoubtedly accounts for part of the performance. There must be more to it than that, however, because the fund showed healthy gains earlier in the year when mainstream energy prices were falling.
Edward Guinness, the fund’s co-manager, points out that demand is surging continually for wind turbines, solar panels and similar devices as consumers come to recognize that supplies of conventional energy will diminish or become harder to locate. At the same time, the industry has become more adept at managing the growth and profiting from it.
“These are serious going concerns with good management teams taking them through a period of fast growth,” he said. Unlike other technologies of the recent past that captured investors’ imagination, like biotechnology and the Internet, Mr. Guinness estimates that 85 percent of the three dozen or so companies in his portfolio will be profitable this year.
“As energy prices rise, more technologies become financially viable, which allows them to manufacture in scale and bring costs down,” he explained. “The field opens up more and more for alternative energy to play a substantial role” in supplying power.
Mr. Guinness, whose firm also runs much larger portfolios focusing on traditional forms of energy, favors three segments of the renewable sector: wind, solar and geothermal. The business model for the last one resembles the oil industry a century ago: invest money upfront, stick a hole in the ground and bank the profits as the earth’s heat is transferred, usually through steam or superheated saltwater, to electricity generators.
The fund owns stocks of two companies that do this on an industrial scale, Ormat in the United States and Geodynamics in Australia. A third holding is W.F.I. Industries, a Canadian company that amounts to a geothermal boutique, supplying pumps and pipes that are buried in backyards to power individual homes.
Wind was one of the first renewable sources to be commercially viable. Turbine manufacturing is especially profitable today, Mr. Guinness said, because demand is outstripping supply, sending prices higher.
He anticipates 25 percent annual sales growth for the sector over the next five years. His preferred vehicles for capturing it are the Danish company Vestas, regarded as the industry leader, and Gamesa in Spain.
Solar is less profitable but Mr. Guinness finds its long-term growth prospects more auspicious. He anticipates 30 percent to 40 percent annual sales increases.
“Solar could grow a hundredfold over 15 years,” he said. “It’s an incredibly attractive area to invest in.”
He has doubled the solar component of his portfolio in recent months to 30 percent of assets. His choices include SunTech Power and Q-Cells, solar cell makers based in China and Germany, respectively, and MEMC Electronic Materials, a Missouri company that produces silicon wafers used to coat the cells.
TWO other holdings that do big business in solar are the Renewable Energy Corporation in Norway and the Colorado company Solar World.
Mr. Guinness added that he was shunning some of the larger solar businesses, like SunPower and Energy Conversion Devices, because their valuations are too rich. He is also wary of whole segments of the renewable energy industry, like fuel cells, which show little likelihood of winning in the marketplace, and ethanol because the plant materials used to make it are too expensive.
But he emphasized that he considers them exceptions in a field with a future that holds much promise and opportunity for those who want to do good and to do right by themselves financially, too.
“We see ourselves at the foothills of a long period of steady growth at high levels,” Mr. Guinness said. “We’re just now beginning to enter the sweet spot where costs are going down and the technologies are becoming economically viable with fossil-fuel technologies. That is going to support significant demand growth.”

TLF takes on Howard

Australia is well behind the US technologically, with slow, expensive, government-owned broadband being the norm (this is changing): however due to its proximity to the poles and the fact that these are the areas which will show the results of man-made carbon first, the country is well ahead of the US in its opinion on green technologies.
Of course I say this realizing there is also a huge public antagonism against nuclear power...well the public can only be so well-informed. The scientific communities are rallying behind nukes--Australia has something like half the world's uranium, so this only makes sense. But I digress.
The interesting thing is that the opposition party has taken up green issues and now both sides are varying shades of green. This is something like the democrat's abandoning of gun-control---once public opinion has shifted so far in favor of an issue there's simply not a party that's willing to back the other side. Hopefully green issues will become as genuinely non-partisan in the states.
My own opinion is that global warming isn't necessary to require pro-green public policy. If Iran ever *really* wanted to declare war they'd just stop selling us oil. That they don't is a sign that Iran's leaders are just puffing themselves up before their public---if they really wanted to catch the ear of American power they'd threaten our oil supply. Or stop buying Pepsi. Remember that the American Revolution was not about blood but about economy---taxation without representation---and when we wanted to shake things up we stopped paying taxes and dumped english imported tea into the ocean.
My point is, renewable energy is not an enviornmental issue. It's a security issue. I view the rest of our lifetimes as an extended cold war with countries battling it out for oil (and, as is attached to cheap energy, low inflation). And, just like WWII, the winner of this war will be the one most willing to dedicate resources to scientific breakthroughs--right now. The risk to the US of failing to find new solutions has little to do with a hundred-year-long warming (although in Oz this has already resulted in losses to agriculture) and more to do with the inflation and joblessness attached to expensive gas, especially in the face of foreign competition.
Anyway here's an article by Tom Friedman--

The Aussie ‘Big Dry’By THOMAS L. FRIEDMAN
SYDNEY, Australia
Almost everywhere you travel these days, people are talking about their weather — and how it has changed. Nowhere have I found this more true, though, than in Australia, where “the big dry,” a six-year record drought, has parched the Aussie breadbasket so severely that on April 19, Prime Minister John Howard actually asked the whole country to pray for rain. “I told people you have to pray for rain,” Mr. Howard remarked to me, adding, “I said it without a hint of irony.”
And here’s what’s really funny: It actually started to rain! But not enough, which is one reason Australia is about to have its first election in which climate change will be a top issue. In just 12 months, climate change has gone from being a nonissue here to being one that could tip the vote.
In the process, Prime Minister John Howard, a conservative now in his 11th year in office, has moved from being a climate skeptic to what he calls a “climate realist,” who knows that he must offer programs to reduce global-warming greenhouse gas emissions in Australia, but wants to do it without economic pain or imposed targets, like Kyoto’s. He is proposing emissions trading and nuclear power.
The Labor Party, led by Kevin Rudd, proposes a hard target — a 60 percent reduction in Australian CO2 emissions from 2000 levels by 2050 — and subsidies for Aussies to retrofit their homes with energy-saving systems. The whole issue has come from the bottom up, and it has come on so quickly that neither party can be sure it has its finger on the public’s pulse.
“What was considered left a year ago is now center, and in six months it will be conservative — that is how quickly the debate about climate change is moving here,” said Michael Roux, chairman of RI Capital, a Melbourne investment firm. “It is being led by young people around the dinner table with their parents, and the C.E.O.’s and politicians are all playing catch-up.”
I asked Mr. Howard how it had happened. “It was a perfect storm,” he said. First came a warning from Nicholas Stern of Britain, who said climate change was not only real but could be economically devastating for Australia. Then the prolonged drought forced Mr. Howard to declare last month that “if it doesn’t rain in sufficient volume over the next six to eight weeks, there will be no water allocations for irrigation purposes” until May 2008 for crops and cattle in the Murray-Darling river basin, which accounts for 41 percent of Australian agriculture.
It was as if the pharaoh had banned irrigation from the Nile. Australians were shocked. Then the traditional Australian bush fires, which usually come in January, started in October because everything was so dry. Finally, in the middle of all this, Al Gore came to Australia and showed his film, “An Inconvenient Truth.”
“The coincidence of all those things … shifted the whole debate,” Mr. Howard said. While he tends to focus on the economic costs of acting too aggressively on climate change, his challenger, Mr. Rudd, has been focusing on the costs of not acting. Today, Mr. Rudd said, Australian businesses are demanding that the politicians “get a regulatory environment settled” on carbon emissions trading so companies know what framework they will have to operate in — because they know change is coming.
When you look at the climate debate around the world, remarked Peter Garrett, the former lead singer for the Australian band Midnight Oil, who now heads the Labor Party’s climate efforts, there are two kinds of conservatives. The ones like George Bush and John Howard, he said, deep down remain very skeptical about environmentalism and climate change “because they have been someone else’s agenda for so long,” but they also know they must now offer policies to at least defuse this issue politically.
And then there are conservatives like Arnold Schwarzenegger and David Cameron, the Tory Party leader in London, who understand that climate is becoming a huge defining issue and actually want to take it away from liberals by being more forward-leaning than they are.
In short, climate change is the first issue in a long time that could really scramble Western politics. Traditional conservatives can now build bridges to green liberals; traditional liberals can make common cause with green businesses; young climate voters are newly up for grabs. And while coal-mining unions oppose global warming restrictions, service unions, which serve coastal tourist hotels, need to embrace them. You can see all of this and more in Australia today.
Politics gets interesting when it stops raining.

future plans

Amanda recently suggested moving to eugene to pursue my green energy plans. Interestingly, i'd already been planning on it!
I've actually been in contact with green energy sales persons in oregon on the basis of living/teaching in Eugene and selling mainly in Bend.
Brandon,

I would very much like to pursue you coming to work for us. Are you going to be coming to the States in the near future? If not, we can explore how we go forward via e-mails. Other possibility is do you get up to Singapore or other parts of SE Asia . I am currently doing some engineering work in Vietnam that requires me to be on site every month or so.

We are also looking at another wind machine manufactured by Mariah Power web site: http://www.mariah-power.com/

Look for ward to hearing from you.

Oregon has the best green incentives of any state and bend (as well as oregon generally) enjoys the highest home appreciation in the country.
If you look at the energy maps, solar power in oregon isn't favorable but wind power is. There are a couple of new 'ipod' -like wind generators that contain everything needed to produce 1-10kW of on-grid power and cost below $10k installed. See

More Stirling

American stirling company infinia (http://www.infiniacorp.com/applications/clean_energy.htm)recently raised for $9.5M in cooperation with the Open Energy corp to make a 3 kW solar-powered, free-piston stirling engine. The unique aspect of the project is the concentrator, called a suncone:http://www.openenergycorp.com/suncone/suncone.php.
A suncone directs light down to the stirling engine, rather than up from a parabolic mirror. They plan on commercializing by 2008.
It appears that the cone idea would work better for my portable stirling notion: a big helium balloon, black, with a number of metallized cones thru its center at all directions and focused to the bottom. You blow the thing up with a cartridge of helium and attach it the the engine, which sits on the ground and anchors the balloon. No need to track the sun---there's a cone in each direction of the spherical balloon. Make the balloon as big as you want: deliver 10, 100 kW, say. Whole thing fits in a backpack, intalls with zero effort. 10 kW silent renewable power in a backpack. The military would go nuts for it.

Whispergen

Recently I visited Christchurch NZ where, among other things, they build the WhisperGen brand of sterling engines. These engines are used stand-alone in boats and as part of a waste heat recapture system in home's water and air heaters. In the lab they had a 3 kW version just larger than my head.
The guy there shared my view that Sterling engines had a promising future as a clean energy alternative. He also believes that a 1 kW engine should be possible for less than $1000 (btw this breaks the $1/W limit that marks how much it costs coal plants to produce electricity. Idea is, if you can create distributed power for LESS than the coal companies PRODUCE it for you can put them out of business. PV's are typically $10-15/W installed into the grid, but this includes the DC/AC inverter (cheap ones at $1500); sterlings don't need an inverter (but have different frequencies, $500 to grid)). But he believes such commercialization is still at least a decade away.
I've been investigating the possibility of 'flipping green houses'. That is, buying a house cheap, putting in efficiency stuff--like PV's, greywater capture, solar water heating, heat pump & computerized thermostat/power control--then reselling it for a premium.
The key is that people perceive the improvements as being greater in value than their real cost. In 1998 the statistic was that people will pay $20 in mortgage for every $1 saved in energy costs per year, this seems to be higher in CA OR and AZ.
With a 30% federal and 25% state tax kickback on green home improvements and an exemption for such improvements in a property tax assessment the picture grows even rosier. Essentially an agent could spend $5,000 improving a home and have that money matched by the government. Therefore the agent spends $5,000 on improvements worth $10,000 and valued, to homebuyers on the west coast, at $10,000-$25,000. The homebuyer gets ~$1000 a year savings on utility costs while adding property value exempt from tax to the tune of ~$150/yr and repays his investment over the lifetime of the mortgage. The agent nets ~$10,000 for a very brief and construction-free improvement.
Or so the idea goes.
My hope is, return to the country and over the next few years position myself for a few years of increased government support from a democratic pres. What if the kickbacks go up?

Melbourne

I'm in Australia.
I've been here six months and it was only yesterday I bothered to notice a toilet flushing.
It's a beautiful city that must draw comparisons with every city you've ever visited. It's such a hodge-podge of British laws (Oz is still a member of the commonwealth), American movies and music, Asian and Pacific Islander ghettos--there's big communities of Greeks and Italians and Turks and who knows what else. Melbourne is a prism that shows whatever you're looking for. Let's just call it England with good weather.
I'm working on completing my PhD and putting work together to apply to various Sterling Engine companies in the states (see the wiki for more info). The largest solar generator ever constructed is currently underway just outside California, comprised of several hundred Stirling Engines running on heat generated by a 25 meter solar dish.
Stirling Engines operate on the expansion of a heated gas: first, a piston is moved as the air in a chamber beneath it expands through contact with a heat source, in this case the focal point of a large mirror. Air (or generally Helium) is then pushed from the hot volume to the cooling volume through what's called a regenerator, which extracts and retains some of the heat. As the air cools the piston is pushed back down by a spring or flywheel. And then the cycle begins again.
Make the piston a magnet and wind a coil of wire around it and you've got a generator. Stirling engines are cheap, many times more efficient than Photovoltaics, contain no parts in contact, are hermetically sealed and will run basically forever. NASA has been running one off radioisotopes continuously for 4 years.
It is also possible to build a heat 'battery' using activated magnesium. Magnesium, the world's third most common metal, is also one of the lightest. Its melting point is therefore quite low, and thus hydrated magnesium (MgH_2) is both an ideal storage medium for hydrogen (and has been proposed as the basis of a hydrogen economy) and for heat energy. In one chamber you put the MgH_2; as this chamber is heated to Magnesium Hydride's melting point it liberates the hydrogen which then passes thru a gasket and is stored in a metal hydrate container (soaking up the hydrogen). By manipulating the hydrogen pressure you can re-hydrate the Mg causing it to give up the heat required to melt it. You could also run an air conditioner off the cold produced in the hydrogen container. Around 0.8 kWh/kilo of Mg may be stored indefinitely in this manner (i.e. a 2-liter bottle could run your house for several hours, depending on the efficiency of the Stirling engine you run off it).
If (and this remains a big if) you could build a 1 kW Stirling Engine for less than $1000, you would in one step solve the world's energy problem. Make the mirrors from inflatable mylar (see NASA's attempts) and they're basically free and the whole thing (engine, mirrors, and battery) fits in a duffel bag. Sell 'em at Wal-Mart.
OK it's a dream but this at least is a solvable problem. "Build a small engine for $1000" is more reasonable than "replace the entire oil infrastructure". Although this must surely happen in our lifetimes.
