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.

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.

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.

Battery Battle

A new type of redox flow battery from the Fraunhofer Institute for Chemical Technology (ICT) offers an advantage for electric cars. If the rechargeable batteries are low, the discharged electrolyte fluid can simply be exchanged at the gas station for recharged fluid – as easy as refilling the gas tank.

Room-Temperature-Cured Copolymers for Lithium Battery Gel Electrolytes

Polyimide-PEO copolymers with branched rod-coil molecular structures, that can be cured into film form at room temperature, have been invented for use as gel electrolytes for lithium-ion electric- power cells. These copolymers offer an alternative to previously patented branched rod-coil polyimides, and an advantage in room-temperature functionality.
