Japan Wins Australia's Global Green Challenge

The "Tokai Challenger" solar car from Japan's Tokai University won the 3,000 kilometer Global Green Challenge race down the center of Australia. The Tokai Challenger maintained an average speed of over 100 kilometers per hour, or about 62 miles per hour, besting the winner of the previous four races - the Dutch Nuon Solar Team.

Three-Dimensional, Hidden Solar Cell

Using zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials, researchers at the Georgia Institute of Technology have developed a new type of three-dimensional photovoltaic system. The approach could allow PV systems to be hidden from view and located away from traditional locations such as rooftops.

Transparent Insulating Film Could Enable Energy-Efficient Displays

Johns Hopkins materials scientists have found a new use for a chemical compound traditionally viewed as an electrical conductor (a substance that allows electricity to flow through it). By orienting the compound differently, the researchers have turned it into a thin film insulator, which blocks the flow of electricity but can induce large electric currents elsewhere.

Research: Reducing Energy Consumption in Street Lighting

Experts from Rensselaer Polytechnic Institute's Lighting Research Center (LRC) estimate that about half of the approximately 13 million streetlights in the U.S. have the opportunity to reduce energy consumption by 50 percent - translating to an annual savings of 1 billion kWh, and a reduction in power plant CO2 emissions of 546,000 tons per year.

Engineers Envision Cheaper Algae Oil Production

Compared to soybeans that produce 50 gallons of oil an acre a year, some algae can average 6,000 gallons - but it's not cheap to produce. Two Kansas State University engineers are assessing systematic production methods that could lower the costs of algae oil production. They plan to grow algae in the ocean on very large, supporting platforms.

Harvesting Energy from Regular, Day-to-Day Motions

Duke University engineers have developed a novel approach that they believe can more efficiently harvest electricity from the motions of everyday life. Although motion is an abundant source of energy, only limited success has been achieved because the devices used only perform well over a narrow band of frequencies.

Silver Nanoparticles Give Polymer Solar Cells A Boost

Researchers at Ohio State University, led by professor Paul Berger, are experimenting with polymer semiconductors that absorb the sun’s energy and generate electricity - with the goal of lighter, cheaper, and more-flexible solar cells. The team has discovered that adding tiny bits of silver to the plastic boosts the material's electrical current generation.
