Technology Review has an article on startup company Kior which has developed a process for creating "biocrude" directly from biomass.

Dutch biofuels startup Bioecon and Khosla Ventures have launched a joint venture called Kior, which will commercialize Bioecon's process for converting agricultural waste directly into "biocrude," a mixture of small hydrocarbon molecules that can be processed into fuels such as gasoline or diesel in existing oil refineries. The process, Kior claims, boasts numerous advantages over other methods of producing biofuels: it could prove relatively cheap, relies on a nontoxic catalyst, taps into the present fuel-refining and transportation infrastructure, and produces clean-burning fuels that can be used in existing engines.

Biofuels are widely seen as a key stepping-stone on the path from fossil fuels to renewable energy sources, particularly for transportation. Their use could also reduce emissions of carbon dioxide and other greenhouse gases. But ethanol, the most widely produced biofuel, contains little energy compared with gasoline or diesel. And a great deal of energy goes into its production: growing the grain from which it is fermented, distilling it, and transporting it. Many biofuels boosters have pinned their hopes on finding ways to produce ethanol from cellulose, the tough polymer that makes up much of plant stems and wood. In practice, though, cellulose must be broken down into simple sugars before it can be fermented into ethanol or converted into synthetic gas and turned into fuels. Despite three decades of research, these remain difficult, expensive, and energy-intensive processes that are not yet commercially viable. Additionally, recent research shows that ethanol, which is highly volatile, may actually exacerbate smog problems when it evaporates directly into the air instead of burning in vehicle engines.

The way to make cellulosic biofuels viable, says Bioecon's founder, Paul O'Connor, is to use catalysts to convert biomass into a hydrocarbon biocrude that can be processed into gasoline and diesel in existing petroleum refineries. After decades developing catalysts for the petroleum industry, O'Connor started Bioecon in early 2006 to develop methods for converting biomass directly into biofuels. His first success is a catalytic process that can convert cellulosic biomass into short-chain hydrocarbons about six to thirteen carbon atoms long. Khosla Ventures agreed to provide an undisclosed amount of series A funding to spinoff Kior in order to commercialize the process. Vinod Khosla, founder of the venture fund, believes that converting biomass into liquid transportation fuels is key to decreasing greenhouse-gas emissions and compensating for dwindling petroleum reserves. Khosla is funding a number of biofuels startups with competing technologies and says that Kior's approach is unique. "They have some very clever proprietary catalytic approaches that are pretty compelling," he says. "They can produce relatively cheap crude oil--that's attractive."

The most effective method of converting biomass into fuel requires subjecting it to high temperatures and high pressure to produce synthetic gas, or syngas. In the presence of a catalyst, the syngas reacts to produce fuels such as ethanol or methanol (used as an additive in biodiesel). But this is a costly process that often results in a product that is too low quality to be used as fuel without further processing. And catalysts able to withstand the high temperature of the syngas are expensive and frequently toxic.

Attempts to produce fuel by directly exposing agricultural cellulose to a catalyst have had little success because most of the cellulose is trapped inside plant stems and stalks. O'Connor says that while the Bioecon researchers are developing new catalysts, their "biomass cracking" process is the real breakthrough. Using proprietary methods, they have been able to insert a catalyst inside the structure of the biomass, improving the contact between the materials and increasing the efficiency of the process. While O'Connor won't go into details, he says that the most basic version of the technique might involve impregnating the biomass with a solution containing the catalyst; the catalyst would then be recrystallized. "What we're doing now is improving the method to make it easier and cheaper," O'Connor says. ...

Steve Deutch, a senior research scientist at the National Renewable Energy Laboratory, says that the little information Kior has released about its process is plausible enough, but that until the details are available, the company's claims are "not really possible to evaluate." The main challenge for Kior, or anyone working on cellulosic fuels, Deutch says, is to develop a process simple enough to bring close to the sources of biomass--farms. "Collecting biomass and getting enough of it in one place to make a difference is a problem in the biomass world," Deutch says. "Trucking costs can become exorbitant. You want to preprocess it at the farm and then ship a high-density, high-energy intermediate to processing plants."

Xinhua reports that China is about to commence mass production of maglev wind power generators.

Construction began on the world's largest production base for magnetic levitation (maglev) wind power generators in central China on Monday. The Guangzhou-based Zhongke Hengyuan Energy Technology Co. Ltd. invested 400 million yuan in building the base for the generators, from which it expects a yearly revenue of 1.6 billion yuan. The base will produce a series of maglev wind power generators with capacities ranging from 400 to 5,000 watts in the first half of 2008, said a company statement.

The maglev generator co-developed by the company and Guangzhou Energy Research Institute under the Chinese Academy of Sciences is expected to create new opportunities for harnessing wind power in low-wind-speed areas, as it can utilize winds with starting speeds as low as 1.5 meters per second.

The problem of the traditional wind turbines was that they require high wind speeds to start, because of the friction caused by their bearings, said Li Guokun, chief scientific developer of the new technology. The frictionless maglev generator would cut the operational expenses of wind farms by up to half, keeping the overall cost of wind power under 0.4 yuan per kilowatt-hour, said Li.

Jeremy Faludi at WorldChanging has a "Green Computing Update" - "Part 1: Data Centers".

It's been a while since we've done a comprehensive article on green computing. So much is happening in this industry that it won't all fit into one article. With this first update, I'll focus on data centers; next week's second update will focus on green personal computers, components, and services.

Before getting started, though, it must be said that greening the computer industry is touching off an unprecedented level of cooperation and information-sharing among companies, government, and laboratories. The Server Specs blog recently interviewed industry consultant Deborah Grove, who said it was unlike anything she'd seen in 24 years in high tech. "There is increased transparency... Executives are offering up what worked and what didn't work instead of everybody having to reinvent the wheel," said Deborah. "It's tangible in the sense of better products... Organizations are taking on the responsibilities that they can deliver on -- not worrying about turf, just trying to get the job done."

Deborah's largely referring to the Green Grid, a consortium of industry leaders (like AMD, Intel, Dell, HP, IBM, Sun, and others who are normally competitors) to share data and strategies for greener data centers. Green Grid's membership also includes the Pacific Gas and Electric Company (better known as PG&E), and it recently announced a collaboration agreement with the U.S. Department of Energy.

Data Centers

Data centers (also called server farms) are where companies like Google or Amazon or internet service providers locate the hundreds or thousands of computer servers that provide their online services. As Worldchanging's Joel Makower has written before in a couple great articles, data centers use massive amounts of electricity; large ones can use megawatts of power, with each square meter using as much power as an entire average US home. According to a Tech Target white paper on green computing, "Data centers consume 1.5 percent of the total electricity used on the planet."

It's not just the computers themselves that use all this power: the combined heat output of all these servers, hard drives and network gear is so large that massive air conditioning is required to keep it all from overheating. "Cooling is about 60 percent of the power costs in a data center because of inefficiency," said Hewlett Packard executive Paul Perez in Data Center News. "The way data centers are cooled today is like cutting butter with a chain saw." Cooling capacity is often the limiting factor of how big these systems can be -- I've talked with more than one engineer whose data center facility sat half empty or more; even though there was plenty of room for more servers, the building's air conditioning was maxed out.

How can data centers get greener?

Lawrence Berkeley Labs has published a white paper titled Best Practices for Data Centers. Researchers measured 21 facilities and recommended strategies that they found most successful. These include several HVAC (air conditioning) improvement strategies, water cooling, efficient power supply and conversion, and on-site power generation. Other useful design strategies the paper does not mention are virtualization and "blade" servers. A paper at GreenIT titled Greening the Data Center: A 5-Step Method actually lists many more than five strategies, similar to those suggested by the LBL, but a bit newer and written for the layman. One step specifically emphasized is getting to know your facilities managers, as they are the ones who know about your HVAC system and energy bills. CIO.com also has a list of six strategies, including not letting your cabling block the flow of your air conditioning system, and moving power and cooling systems outside the data center -- even outside the building. ...

TreeHugger's quote of the day comes from Jonathan Porritt on Saving Our Seeds.

The number of people out there today seriously worried about the health of all the plants and seeds on which modern agriculture depends must be very limited, and the number of people actively campaigning to protect them vanishingly few. ... Of the Earth's 250,000 plant species, only 200 are cultivated for food on any serious scale.

Even more extraordinary, the vast majority of the world's food comes from just 20 crops, in just eight plant families. Most of these monocultures are dangerously vulnerable to diseases (both old and new), pest infestations, and a rapidly changing climate.

Yet the "genetic pool" on which plant breeders might need to draw to build resistance and adaptability is being constantly eroded as older, non-commercial varieties disappear. ...

[S]eed banks can only do so much in this massive salvage operation. The seeds they store need to regularly germinated, otherwise they too die. The best way of maintaining an active and vibrant seed bank is to ensure that farmers (and gardeners) are planting out those 'land races' and rare varieties of plants which are now so endangered.

More often than not, that sets small-scale, subsistence farmers (on whom this kind of "active conservation" depends) in conflict with the juggernaut of industrialised, intensive agriculture."

The FT reports that Brazilian oil company Petrobras has made a large offshore find in the Atlantic. Apparently the proven reserves are only about 700 million barrels, so its not huge in the grand scheme of things.

Brazil’s state oil company Petrobras unveiled on Thursday a giant crude reserve, sending its shares soaring and prompting the government to withdraw 41 oil blocks from an upcoming auction in a bid to keep potential natural resources out of foreign hands. ”This is about preserving the country’s sovereignty, while maintaining the auction with areas that are not linked to the discovery,” cabinet chief Dilma Rousseff said at a news conference, explaining the decision to pull blocks linked to the find from a concessions auction on Nov. 27-28.

Petrobras made Brazil’s largest oil find at great depth in the subsalt cluster at the offshore Santos basin field called Tupi. The crude is 28 API grade, unusually light for Brazil. Petrobras said tests allowed it to estimate recoverable reserves of between 5 billion and 8 billion barrels -- about half Brazil’s existing proven reserves. Company officials said commercial production could begin in five to six years. A pilot project should start in 2010 or 2011 with an aim to gradually reach an output of 100,000 barrels per day.

The Age has a new article by Kenneth Davidson on climate policy - "The major parties' green credentials are off the rails".

A fixation with road transport compromises climate change policy.

RUDD Labor's green credentials are slipping. And you don't have to look far for the reasons. Until Labor produces interim greenhouse gas targets for 2020, and policies to match, the promise of a 60 per cent reduction in greenhouse gas emissions by 2050 just remains so much hot air.

On the ALP's election website there were 29 transport policy promises — 27 involved specific pledges for road funding totalling $8.3 billion and two "vision" statements on shipping and rail in speeches by shadow transport minister Martin Ferguson in July and August.

These speeches don't commit a dollar expenditure or give even an indication of the roles shipping and rail might play in achieving greenhouse targets. Nor do they mitigate the double whammy of peak oil (which is driving world oil prices towards $100 a barrel) and Australia's "oil squeeze" as declining domestic production and rising demand will push oil self-sufficiency from a present 84 per cent to 20 per cent in the next two decades.

Gilles d'Aymery at Swans has an article on "The Inexorable March Into Iran: The American People's Forgivable Irresponsibility", predicting a likely strike on Iran between February and April 2008.

"Why, of course, the people don't want war," Goering shrugged. "Why would some poor slob on a farm want to risk his life in a war when the best that he can get out of it is to come back to his farm in one piece. Naturally, the common people don't want war; neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But, after all, it is the leaders of the country who determine the policy and it is always a simple matter to drag the people along, whether it is a democracy or a fascist dictatorship or a Parliament or a Communist dictatorship."

"There is one difference," I pointed out. "In a democracy the people have some say in the matter through their elected representatives, and in the United States only Congress can declare wars."

"Oh, that is all well and good, but, voice or no voice, the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same way in any country."

—Hermann Wilhelm Göring in a conversation with Dr. Gustave M. Gilbert, Nuremberg, April 18, 1946 (see Nuremberg Diary, New York: Farrar, Straus and Giroux, New York, June 1947, ISBN 0374223519 - pp. 278-279).

Unfathomably, Iran tops the chart of all the countries viewed by the American people as the biggest threat to the U.S., ahead of the perennial culprits -- China, Iraq, and North Korea, soon to be rejoined by the old scarecrow of yesteryears, Russia. If Iran develops the bomb, the American people in their overwhelming majority believe that Iran will attack Israel, Europe, or the United States. They further believe that Iran will provide terrorist organizations with some sort of nuclear device to attack the U.S. Not surprisingly, a majority of likely voters support a military strike against Iran and believe it will happen before the end of the Bush administration on January 20, 2009. But no worries, 30 senators have signed a letter telling Mr. Bush he had no congressional authorization to attack Iran, and the administration steadfastly repeats that the president wants diplomacy to work with the help of our friends and allies. The corporate media, meanwhile, keep ringing the alarm bells -- the Iranians are coming, the Iranians are coming! -- and the antiwar forces, or what remains of them, are increasingly being muffled by the forces of Law and Order.

First and foremost it should be noted that as abundantly explained in "Propaganda: Then and Now" (Swans, November 12, 2001) propaganda does indeed work. "Propaganda means repetition and more repetition!" Joseph Goebbels, the Reich Minister for Popular Enlightenment and Propaganda in Nazi Germany, used to say. "Nuclear Holocaust," "World War III," "Israel wiped off the map," "mushroom clouds," "the new Hitler," "this is 1938," "state-sponsor of terrorist organizations," "killing American troops through proxy militias," "arming and training the terrorists," "irrational mullahs," "islamofascists," "financing and training Hezbollah and Hamas," and all combinations therein repeated ad nauseam on cable and network news programs, in the written press, the blogosphere, the Congress, and in hundreds of position papers from countless think tanks right, left, and center. Even the humanitarian hordes are on board to defend women's rights and freedom of the press; supposedly, the anarcho-libertarian left is falling back on their sempiternal "neither-nor" position that they used so fruitfully with Milosevic and Saddam Hussein: Neither Mahmoud Ahmadinejad nor the U.S. It looks eerily like the fall of 2002 all over again.

It may be disappointing to observe the American people being taken for another wild destructive ride, but in their defense, that's all they hear. Göring was right on mark, "it is always a simple matter to drag the people along." That the people have turned against the Iraq War, yet 41 percent still "believe" that Saddam Hussein's Iraq was behind 9/11, ought to be viewed as simple forgivable irresponsibility. They don't know because they are not being told (or are actually being fed falsehoods and disinformation), aren't naturally curious, and are quite possibly the most insecure people on the surface of the globe. Fear is the common denominator of the American psyche all the way back to the first colonies in the 1700s and the birth of the nation. Enemies are always looming behind dark, dangerous, smoky clouds to take their life, liberty, and pursuit of [material] happiness away from them. Imbued with a sense of innate goodness, permeated by pseudo-religions, infused with the conviction that America is the best country in the world, any dissenting views or oppositions are inevitably deemed a sign of evil. Evil roams the world, envious of our freedoms and way of life, always seeking to destroy America, the last best hope on planet Earth. Our god-given right, besides going to the Mall, is first and foremost to defend ourselves against the dragons that wish to set us afire, with or without the help of our ever-changing friends and allies. ...

Red Herring has a look at ex-Australian solar thermal power company Ausra and their expansion plans in the US and beyond.

Standing out in the increasingly crowded solar energy space isn’t easy these days. But Australian-American startup Ausra seems to have managed to do just that. Named after an ancient Indo-European goddess of the dawn, Palo Alto, California-based Ausra is a solar thermal technology company that, unlike many of its rivals, touts a means to produce electricity from sunlight that requires less fuss than conventional methods and could lower the cost of generating utility-scale power.

“You’d be mad to build a gas plant or a coal plant when there are technologies like this around,” said CEO Peter Le Lièvre, who helped form the company late last year. Solar thermal power plants capture heat from sunlight and use it to generate electricity.

Ausra uses relatively inexpensive 40-foot-long flat plate mirrors–called Fresnel reflectors–to concentrate the sun’s rays directly on water pipes, boiling the water to run steam turbines, which, in turn, generate electricity, according to a company representative. The system, which the company says has the potential to generate electricity for two-thirds the cost of its competitors, has attracted more than $40 million in funding from Khosla Ventures and Kleiner Perkins Caufield & Byers, Ausra said Monday.

Concentrated solar power plants generally use trough-like structures whose curved mirrors focus sunlight onto tubes of oil. The heat from the oil is then used to create steam and to drive the electricity-generating turbine. But the mirrors must be precisely shaped and mounted on sun-tracking devices, requirements that make them more costly to make and repair, according to Ausra’s executive vice president, John O’Donnell.

Ausra says its system can bring down the cost of solar power-generated electricity to be competitive with conventionally generated electricity. Ausra’s Freshnel reflectors are flat, unlike the curved, finely tuned mirrors of the traditional trough design, according to the company. “It’s a mindset that’s much more like Toyota than like NASA,” Mr. O’Donnell said. Ausra also directly heats water to generate steam, rather than first heating oil to generate heat. But the system is less efficient at converting solar energy to electricity than trough systems because it generates lower-temperature steam, Mr. O'Donnell said.

Ausra was originally founded in 2002 as Solar Heat and Power in Australia by David Mills, who originated the technology in the early 1990s at Sydney University, and Graham Morrison, who helped him develop it from 1995 to 2001. Solar Heat and Power built a one-megawatt pilot project in Australia for Macquarie Generation in New South Wales in 2004. The company, which changed its name to Ausra and moved to the United States in February, is also working on a second 38-megawatt capacity power plant it expects to have finished by 2009.

The company plans to build a 180-megawatt power plant at an undisclosed United States location, and is beginning construction on a 6.5-megawatt plant in Portugal, according to Messrs. Le Lièvre and O’Donnell. The company also plans to open offices in California, Colorado, and Arizona and to double its staff to 100 by the end of the year, they said.

After Gutenberg also has some comments on Ausra, noting the system is still dependent on water availability - though this is purely for turning turbines rather than cooling as in many coal and nuclear plants, so presumably this could be a nearly closed loop system (more at San Jose Mercury, Clean Break and The Energy Blog).

Ausra’s core technology is the CLFR (Compact Linear Fresnel Reflector). Instead of the parabolic troughs or mirrors used in other solar thermal systems, this form of CSP (Concentrating Solar Power) uses flat reflectors moving on a single axis plus Fresnel lens to concentrate the solar thermal energy in collectors. Flat mirrors are much cheaper to produce than parabolic ones. Another advantage of CLFR is that it allows for a greater density of reflectors in the array. David Mills originally conceived of the approach in the early 1990s while at Sydney University.

Currently, Ausra is building a 30 MW solar thermal electric power plant, and in the process of scaling up to 2,000 MW over the next three years — enough power for two million homes in the United States. Founded by Dr. David Mills (who has spent the past three decades in Australia), Ausra got its big break last summer; Mills got to meet solar thermal advocate and venture capitalist, Vinod Khosla. “It’s a great story, really,” observers Toronto Star reporter, Tyler Hamilton1. “After years of trying to attract serious interest in his technology in Australia, Mills says he was getting ready to throw in the towel and retire.” ...

“Worldwide, the electric power industry creates 40 percent of total carbon emissions, and electricity use is rapidly growing. Ausra’s technology serves a critical need for utilities seeking large-scale affordable sources of clean power to meet the dual challenges of economic growth and carbon constraints,” said Vinod Khosla, founder of Khosla Ventures and Ausra investor and board member.

One solar thermal electric power plant, the 354 MW SEGS (Solar Energy Generating Systems), which covers 1000 acres in the Mojave Desert in Southern California, produces 90% of the world’s commercially produced solar power. One might perceive such a major effort as an impetus for new investors to believe in the potential of solar thermal.

Ausra aims to expedite the utility industry’s transition to clean energy, helping utilities meet renewable portfolio standards while keeping rates low and the power on for consumers day and night. “Economic development around the world, coupled with recognition that carbon emissions must rapidly be eliminated, has created an enormous market opportunity for companies that can deliver solar power at large scale and at reasonable cost,” says KPCB Partner and Ausra investor and board member Ray Lane.

Lane sees solar thermal electric power generation as a “main event in renewable energy”. It may be, provided that potential water shortages are addressed. As with other steam turbine systems, solar thermal is susceptible to a shortage of water.

The press release did answer one question. I wondered why, since investors were willing to put $40 million into CSP, specifically the Ausra Compact Linear Fresnel Reflector, then had foregone the combined technology developed at MIT. “We had been working on a wide range of alternatives and kept finding that simpler, cheaper approaches outperformed higher-temperature, more sophisticated designs,” says Ausra Chairman David Mills.

Technology Review has an article on cheaper solar cells from thin film solar manufacturer Heliovolt.

Powered by $77 million in new investment, startup Heliovolt, based in Austin, TX, will build a factory next year for mass-producing a new type of solar cell that could, in much of the United States, make solar electricity as cheap as electricity from the grid. The company will be scaling up a new manufacturing technique that could produce high-performance thin-film solar cells more reliably than other methods.

Heliovolt is one of several startups developing a type of thin-film solar cell that converts light into electricity with a micrometers-thick layer of a copper-indium-gallium selenide (CIGS) semiconductor. Thin-film solar cells are attractive because they could produce electricity cheaper than conventional silicon solar cells. Although thin-film cells produce less electricity per square meter than conventional silicon solar cells do, they make up for this by using orders of magnitude less active material per square meter. This can result in significant savings. For example, generating one watt of electricity requires about 80 cents' worth of silicon, but it only requires a penny's worth of a semiconductor used in a thin-film cell, says John Benner, who manages electronic materials for photovoltaics research at the National Renewable Energy Laboratory (NREL), in Golden, CO. (Heliovolt is working with NREL to further develop its cells.)

The challenge has been to reliably make thin-film solar cells at a large scale. In the lab, CIGS solar cells have shown the highest efficiency of any thin-film cell (19.5 percent), exceeding that of some types of silicon solar panels made today. But, while no one expects to reach this level of efficiency in mass-produced cells, it has proved difficult to reliably make them with even a minimum level of efficiency needed to compete with other types of solar cells.

Heliovolt's new manufacturing method, however, could prove more reliable than others, Benner says, by providing more control over the composition of the semiconductor film. ...

So far the company has demonstrated the process only on relatively small, 15-centimeter-wide solar modules. Its goal for early next year is to build a factory to produce, first, 30-centimeter modules, and later--most likely sometime after June--prototypes of modules that are about three-quarters of a square meter (60 by 120 centimeters). The larger size is necessary for bringing the product in line with standard module sizes, making them cheaper to install. The factory will be designed to produce enough cells per year to generate 20 megawatts of electricity at first, and eventually 40 megawatts. A typical wind turbine, in comparison, might generate two megawatts of electricity.

The first of the company's large cells will have efficiencies of 10 to 12 percent, Stanbery estimates, or slightly better than other thin-film solar cells. In 10 years, he expects those figures to increase to 13 to 15 percent, or good enough to compete with some types of conventional silicon solar cells. Stanbery also expects to manufacture cells for less than First Solar, a Phoenix, AZ-based maker of a different type of thin-film solar cell that has seen high demand for its products.

Red Herring also has an article on Finavera Renewables and their wind and water power plans.

Jason Bak, an applied physicist by training, found gold and diamonds in the Canadian arctic in the late 1990s using electromagnetic techniques. In Ireland, he worked for a gold mine that sold for 30-times its purchase price. But it was a less ostentatious money-making prospect that inspired him to launch Finavera Renewables, a Vancouver-based startup that sees a business opportunity in producing electricity from wind and ocean waves. Unlike gold, whose price can be extremely volatile, electricity generated by wind mills and offshore wave farms is a commodity whose future is always bright, argues CEO Mr. Bak. “Electricity only gets more expensive,” he said. “It never gets cheaper. It’s a commodity that’s always growing in price.”

Finavera’s approach is to use wind projects to generate revenue, while the company works to develop its wave energy technology, according to Mr. Bak. That fledgling technology took a couple of baby steps last week a few miles off the coast of Newport Beach, Oregon, where Finavera put the latest version of its wave energy converter device, dubbed AquaBuOY, into the Pacific. The device floats atop the ocean and uses rubber hose-pumps to convert the vertical motion of the waves into pressurized seawater. That pressurized seawater, in turn, powers the turbines that drive an electrical generator. Previous versions, according to Mr. Bak, used metal rods, which were more costly and more trouble to maintain. This stepping stone “allows us to prove the concept,” said Mr. Bak. “The next step is simply increasing the power output of our technology [which would] reduce our unit cost of energy.” AquaBuOY generates a maximum of 250 kilowatts at any instant in time, he said.

Finavera’s system is moored, rather than mounted, to the ocean floor. That simple feature means less red tape and fewer headaches, as regulations for seafloor-mounted installations can be complicated, the company said.

Next year the company plans to develop and test the third-generation of AquaBuOY and, by 2009, it hopes to put four of the devices in the water and connect them to the grid via an undersea transmission line, Mr. Bak said.

In addition to the Newport Beach test site, Finavera has a demonstration site in Makah Bay, Washington, and is developing projects in Coos County, Oregon; Figueira da Foz, Portugal; Ucluelet, Canada; and South Africa.

The Australian and The Age note that new company Wind Hydrogen has floated on the ASX at a discount to its issue price, however I think the model of combining renewable power with energy storage technology will be standard practice before too long.

Wind Hydrogen's $12 million whip-around is aimed at developing a pipeline of early stage projects, mainly in Britain but also in Victoria. Wind Hydrogen boasts a patented hydrogen balancing system, by which off-peak wind energy is used to create hydrogen for use in high-demand periods.

Not even the exhortations of Wind Hydrogen's venerable chairman -- The Honorable Neville K. Wran AC, QC -- were enough to save the 20c shares from tanking, admittedly on a crap day to list. Wind Hydrogen notes the company does not have any producing wind farms -- or in some cases approval to build such a facility -- so is "speculative in nature".

IEEE Spectrum has an article on zero emissions buildings.

It may be a first: an office building with a net electricity use of zero or less, that burns no fossil fuels for heating and produces no greenhouse gas, and that makes the people working there at least as comfortable as those in conventionally heated and cooled buildings. The building, in San Jose, Calif., opens in October, and if all goes according to plan, it will raise the bar for designers of energy-efficient buildings worldwide. Though other so-called z-squared buildings exist, they are highway rest stops, nature centers, and event locations, not office structures with computers and printers and cubicles full of employees.

“We’ve hoisted the flag and said we’re the first,” says David Kaneda. “No one yet has stepped forward to question that.” He owns the San Jose building, and his Santa Clara, Calif.–based firm, Integrated Design Associates (IDeAs), did the electrical and lighting design and will occupy the ground floor.

The building was once a windowless bank, designed in the 1960s when banks were meant to be riot-proof concrete bunkers. Today, with the remodeling nearly completed, it is modern art: the exterior is broken up with rows of windows and swaths of blue and gray paint, while solar panels adorn the roof, with skylights pushing up in between.

Kaneda embarked on the project of renovating the old bank in September 2005, with the goal of creating an environmentally friendly building that could earn a Platinum rating—the highest—from the U.S. Green Building Council, an association of builders in Washington, D.C. At that time, global climate change was not in the forefront of public consciousness, and the council’s standards were not much in the public eye. So Kaneda thought he was being very forward-thinking when he proposed to renovate the bank to meet the council’s specifications for building materials, water use, indoor air quality, and—most important—energy use.

But when Kaneda hired architect Scott Shell, from EHDD Architecture, in San Francisco, to work on the project, Shell went even further, suggesting they design a building with no net electricity usage and no carbon dioxide emissions. “It was a shock to me when he said that,” Kaneda recalls. He didn’t know of any commercial buildings that had gone that far.

The idea appealed to Kaneda, and the two decided they would disconnect the natural gas pipes running to the building and find heating alternatives. They would stay on the electric grid but install enough photoelectric panels to cover the entire energy load—about 30 kilowatts, generating more electricity than the building uses during the day but pulling a small amount off the grid at night. Since they’d be limited by the size of the roof, they’d have to be clever about energy use.

“To cut down on energy use, you’ve got three areas to address,” Kaneda says, “lighting, heating and cooling, and plug load—that is, the computers, printers, microwave ovens, and other things you plug into the wall.” ...

Energy Bulletin points to a review of a book called "Renewable energy cannot sustain a consumer society" by a local professor at UNSW named Ted Trainer. I'm increasingly baffled by these sorts of claims - there is far more energy available from renewable energy sources than we could ever use, even in the most wasteful consumer society spread to every person on the planet. Many of the technologies to do this are well proven and fairly cheap (wind, solar thermal, solar hot water) or rapidly becoming viable (thin film solar, geothermal, ocean energy sources, some biofuels) and the supplementary technologies required to make it all work (energy storage, demand management techniques) are also becoming widely understood and getting ready to be rolled out. So where do people get these "energy descent" ideas from ?

Ted Trainer, of the University of New South Wales, has made a valuable contribution to the literature of energy and resource depletion with his new book Renewable Energy Cannot Sustain a Consumer Society.

The title says a lot I think. With the focus of most mainstream debate on peak oil and energy being on the supply side - the oil is running low so what are we going to use instead? - Trainer brings a refreshing approach in which he provides a detailed and technically comprehensive analysis of existing renewable energy options- including wind, solar thermal, solar electric, biomass and energy crops, and hydrogen, as well as nuclear and the issue of storing energy. He concludes:

…we could easily have an extremely low per capita rate of energy consumption, and footprint, based on local resources- but only if we undertake vast and radical change in economic, political, geographical and cultural systems.

In the first section he outlines the context in which these discussions have been taking place: a context full of “Greenwash” and wild exaggerations on behalf of some renewable energy suppliers, which has been repeated by the media and left the public with a quite illusory understanding of what renewables can and cannot do. ...

Bart at Energy Bulletin comments "Trainer's figures on renewables have been and will continue to be disputed. However, one thing is not in dispute. The move away from fossil fuels will be much much easier with some of the cultural changes that he describes as 'The Simpler Way.'". While I've got no problem with people implementing any of the many "dark green" options out there, I fail to see the point in grossly underestimating the availability and reliability of "bright green" alternatives - both will be needed in future, and both will be put into play...
