Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.

WorldChanging has a brief post pointing to a symposium on urban life after oil - Re-Imagining Cities: Urban Design After the Age of Oil. A number of great journalists were covering last weekend's Re-Imagining Cities: Urban Design After the Age of Oil symposium in Philadelphia. The University of Pennsylvania School of Design and Penn Institute for Urban Research hosted this conference, which was organized with support from the Rockefeller Foundation to address the need to re-imagine and rethink how cities are designed and organized in a future without oil. Our own Alex Steffen gave a mainstage talk at the international event, which featured a number of thinkers whose work we've written about before here, like Bull Dunster, Elizabeth Kolbert, Robert Socolow, Andy Revkin, William J. Mitchell, David Orr, Neal Pierce, Bill Rees, Thomas Campanella, Harrison Fraker, and ARUP's Sir Peter Head. From brief recaps of plenaries and workshops to lengthier discussions of the theories presented (and their presenters), the pieces posted to the Next American City liveblog offer a taste of what was seen and heard at this innovative gathering of great minds.

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.

The current energy crisis has made American voters look more favorably on a wide range of ideas that can be used to deal with our energy problems. But voters don't favor all of these ideas equally; they have clear views on which approaches they think will work best. Consider these data from a recent Quinnipiac University poll of voters in four key swing states: Colorado, Michigan, Minnesota, and Wisconsin.

For coal, the future of both extraction and consumption depends on new technology. If successfully deployed, innovative technologies could enable the use of coal that is unminable by gasifying it underground; reduce coal's carbon emissions; or allow coal to take the place of natural gas or petroleum. Without them, coal simply may not have much of a future. Are these technologies close to development? Are they economical? Will they work?

If electric vehicles aren't your thing, then you may be pleased to hear that at least one company is working on giving that tried and true internal combustion engine a major boost. Artemis, an Edinburgh, Scotland-based company, has developed a hydraulic hybrid transmission that could potentially double the mileage of most vehicles -- by accident, as it happens. The firm's original goal had been to simply reduce CO2 emissions on the highway by 30% (a goal it also achieved).

Clean energy. It's real. It's here. It's working!

In this small region of Nigeria known as the "south-south," something huge is happening. The adverse effects of oil exploration have been unfolding in the Niger Delta for the past 50 years. Now, the people have had enough. From environmental activism to peaceful protest to stakeholder dialogs, nothing has worked. A new brand of militancy has emerged in a different kind of attempt to call attention to the desperate poverty and injustice.

A new lobbying firm for the group opposing a wind farm off Cape Cod filed a federal document last month reporting that its work for the Alliance to Protect Nantucket Sound is partially funded and shaped by an international energy conglomerate.

James Dyson is working on a solar-powered car to match the success of his bagless vacuum cleaner. Engineers at the entrepreneur's Wiltshire HQ are developing a lightweight electric motor that could power a family saloon for hundreds of miles.

Warnecke, a researcher at the U.S. Department of Energy's Joint Genome Institute in Walnut Creek, California, has been generating lots of attention lately for his work with termites. The insects are remarkably efficient at turning cellulose into sugar-the first step in making fuel from plants like switchgrass or poplar trees. Scientists can't compete with termites.

A Canadian company says that it has developed a way for makers of precast concrete products to take all the carbon-dioxide emissions from their factories, as well as neighboring industrial facilities, and store them in the products that they produce by exposing those products to carbon-dioxide-rich flue gases during the curing process. Industry experts say that the technology is unproven but holds great potential if it works.

Climate change will carry a price tag of billions of dollars for a number of U.S. states, says a new series of reports from the University of Maryland's Center for Integrative Environmental Research (CIER). The researchers conclude that the costs have already begun to accrue and are likely to endure. Combining existing data with new analysis, the eight studies project the long term economic impact of climate change on Colorado, Georgia, Kansas, Illinois, Michigan, Nevada, New Jersey and Ohio. Studies on additional states are in the works.

Twenty-five years ago, when I was CEO of Intel, I had an unusual experience while visiting a customer. It was during a period of tight availability of microprocessors, our main product. This was not an unusual state of affairs. Supply and demand ebbed and flowed as the computer business had its ups and downs. Sometimes we had too many chips sitting in inventory; other times, like this one, we had too few. My main purpose in visiting was to reassure the customer that we were working hard to boost production and that relief was on the way.

A leading U.S. Senate Democrat accused the Bush administration on Tuesday of a "cover-up" aimed at stopping the Environmental Protection Agency from tackling greenhouse emissions. "This cover-up is being directed from the White House and the office of the vice president," said Sen. Barbara Boxer, the California Democrat who chairs the Senate Environment and Public Works Committee.

A major tidal energy project is being planned for waters off the coast of Northern Ireland and Scotland. ScottishPower has identified sites off the Antrim Coast, Pentland Firth and the Sound of Islay to test sea turbines which could power thousands of homes. They have been working on the Lanstrom device, which is said to be one of the world's most advanced tidal turbine.

Engineers and scientists at The University of Texas at Austin have achieved a breakthrough in the use of a one-atom thick structure called "graphene" as a new carbon-based material for storing electrical charge in ultracapacitor devices, perhaps paving the way for the massive installation of renewable energies such as wind and solar power. The researchers believe their breakthrough shows promise that graphene (a form of carbon) could eventually double the capacity of existing ultracapacitors, which are manufactured using an entirely different form of carbon. "Through such a device, electrical charge can be rapidly stored on the graphene sheets, and released from them as well for the delivery of electrical current and, thus, electrical power," says Rod Ruoff, a mechanical engineering professor and a physical chemist. "There are reasons to think that the ability to store electrical charge can be about double that of current commercially used materials. We are working to see if that prediction will be borne out in the laboratory."

A group of Spanish developers working for a company called Ecofasa just announced a new biofuel made up from trash. This isn't a biodiesel made from used frying oil; instead, it's made from general urban waste which is treated by bacteria. The result of that bacteria? Fatty acids that can be used to produce standard biodiesel. According to the company's CEO, the process is fully biologic, competes with no feedstock and is really sustainable. However, the process doesn't yield that much actual fuel: just one liter of biodiesel from 10 kg of trash. The project is now in a development phase, but Ecofasa said that a commercially viable model could be ready in three to four years.
