Here's a wave power technology which you may not have heard of: It's called the Searaser and (though only in prototype stages, I've got some reservations about how well it may scale up, as well as the name which somehow I always see as 'Sea Eraser') it may be worth watching. The principle is fairly simple and proven in a different context: Use the Searaser to pump quantities of sea water up a hill where it can be stored in ponds until needed and then released downhill to drive hydroelectric turbines to create power. This is how the Searaser works:

The University of California today issued a report concluding that if California improves energy efficiency by just 1 percent per year, proposed state climate policies will increase the Gross State Product (GSP) by approximately $76 billion, increase real household incomes by up to $48 billion and create as many as 403,000 new jobs.

With a new President and Congress, we have an unprecedented opportunity to transform our fossil fuel economy to one based largely on clean energy, while creating millions of jobs in the process. Last month, we offered a Clean Energy 2030 proposal for how the U.S. can dramatically scale up renewable energy, become smarter about how we use energy, and deploy millions of plug-in electric cars. Our energy team has continued crunching the numbers and just posted new data on job creation and cost savings on our knol. We'll keep updating the information and encourage everyone to take a look and comment - and offer alternative approaches if you disagree. Reaching the goals of Clean Energy 2030 will require a comprehensive effort by the new President and Congress.

Researchers developing alternatives to fossil fuels are working with everything from algae to babassu oil to corn, but a California company says it can recycle carbon dioxide into fuel. Carbon Sciences claims it has developed a way of using the CO2 emitted during the combustion of coal, oil and other hydrocarbons to create transportation fuels like gasoline and jet fuel. Should Carbon Sciences - or any of the other firms working on similar projects - accomplish this on a large scale, it could bring a reduction in CO2 emissions as well as an abundant supply of renewable fuel.

Following last summer's record minimum ice cover in the Arctic, current observations from ESA's Envisat satellite suggest that the extent of polar sea-ice may again shrink to a level very close to that of last year. Envisat observations from mid-August depict that a new record of low sea-ice coverage could be reached in a matter of weeks. The animation above is a series of mosaics of the Arctic Ocean created from images acquired between early June and mid-August 2008 from the Advanced Synthetic Aperture Radar (ASAR) instrument aboard Envisat. The dark grey colour represents ice-free areas while blue represents areas covered with sea ice.

Their mission: to deliver cost-efficient solar electricity. The Nanosolar company was founded in 2002 and is working to build the world's largest solar cell factory in California and the world's largest panel-assembly factory in Germany. They have successfully created a solar coating that is the most cost-efficient solar energy source ever. Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt.

Hydrogen cars get no respect. A lot of people consider them the stuff of science fiction, a technology as vaporous as the stuff that drives them. But despite some hurdles even Liu Xiang couldn't clear -- creating a fueling infrastructure comes to mind -- Uncle Sam and the big automakers love hydrogen cars and are driving across the country in a fleet of them to prove they work. Even if they're occasionally hauled on trucks.

ABOUT THE PANEL DISCUSSION: Companies sometimes regard sustainability as "metaphoric low-hanging fruit," says moderator Peter Senge, and reach for a few easy targets to achieve cosmetic improvements. His three panelists describe how their corporations are attempting to embrace sustainability as more than just another high-profile, low-impact initiative that "goes right into an overloaded bucket."

We can't afford to think of business as the enemy. Businesses in many cases are realizing the importance of sustainability more quickly than the public sector which too often defines its view by outdated political philosophies. This video provides a great deal to think about.

Out on a lawn at the Massachusetts Institute of Technology with joggers and traffic passing nearby, Spencer Ahrens is demonstrating what looks like either the future of solar power - or perhaps a death ray.

Textiles have been a fixture of architecture and design for their ability to define and modify a space. For Sheila Kennedy, textiles are just another material from which energy can be generated. The thin-film photovoltaic textiles are essentially solar panels created from organic photovoltaics. While not as efficient as the silicon based type, they are able to be molded and modified without any manufacturing process.

Hydrogen Garage LLC is just what it says : "a garage operation". Garage to Garage. An online business selling parts to make home made hydrogen cells, parts, circuits, etc. for the home mechanic/technical /experimenter. We do NOT sell consumer products, only parts for the genius in you. A simple add onto your existing vehicle and or gas powered generator. Might as well sell something that helps clean our car's emission, save MPG and clean up your engine and create more horsepower and help stop Global Warming from too much carbon monoxide posioning. Way better product that some of the stuff that people can sell online today. The more the exposure of "on board electrolysis" the better.

The government plans to announce policy measures aimed at halving the price of solar power generation in the next three to five years as part of its action plan on greenhouse gas emissions, government sources say. According to the sources, the measures will form part of an action plan designed to bring about a 60 percent to 80 percent cut in carbon dioxide emissions by 2050 and thereby create a low carbon-emission society.

We have been, for quite some time, up against a corporate-funded, what I have called global warming denial machine, or disinformation campaign, whose fundamental aim has been to create an exaggerated sense of scientific uncertainty about human-driven global warming and its consequences.

While certain American politicians complain about a million bucks being included in the country's energy plan to promote bikes, in the UK they are investing £140 million (about US$ 280 million) to create dedicated bike lanes, provide bike parking, safety training, on-street bike rental networks and a campaign to promote bicycling in 12 Cycling Demonstration Towns.

Looking to make solar panels cheaper, MIT researchers have created sheets of glass coated with advanced organic dyes that more efficiently concentrate sunlight. The researchers, whose results appear in this week's issue of Science, say that the coated glass sheets could eventually make solar power as cheap as electricity from fossil fuels.

The UK government's renewables consultation called for a green revolution in energy. In doing so, it created a perfect tabloid rod for its own back. The proposed cost-to-consumer calculated by the Department of Business were based on the vanishingly unlikely prospect of an oil price as low as $70 a barrel in 2020. Expected additions to UK energy bills, at that oil price, would be 10-13% for electricity and 18-37% for gas, the government said.

An unusual combination of economic and environmental forces have created a "perfect storm" that could help geothermal shed its back-seat status to its renewable cousins wind and solar energy, experts said at an international conference. One after another, state and federal regulators, oil company executives, investor-owned utility officials and private developers on Monday recited the conditions in play to an overflow crowd of more than 1,000.

T. Boone Pickens, a conservative billionaire who made his money in oil, is creating strange bedfellows with his aggressive plan for renewable energy such as wind power and natural gas. Last month, he held two conference calls with more than 27,000 members of the Sierra Club to talk up the plan. The environmental group, with some reservations, is on board. Last week, he met with Al Gore. Today, he is scheduled to be on the University of Michigan campus, selling his ideas to students. He said he expects a packed house.

Integrating solar cells into building materials could make solar power more attractive to homeowners. Seamless solar: The solar system shown here (darker panels) integrates thin-film solar modules directly into a metal roof. Such systems offer cost savings in labor and materials and blend well with buildings' designs. Credit: EnergyPeak In an effort to promote the adoption of solar technology, United Solar Ovonic of Auburn Hills, MI, has teamed with a major roofing company to create a metal roof system that generates electricity from sunlight. The partnership offers seven different prefabricated systems, ranging in capacity from 3 to 120 kilowatts. Tests show that the solar roof panels are rugged and can withstand winds in excess of 160 miles per hour.
