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.

Modular Electronic Air Sterilization Technology

This germicidal irradiation system eliminates airborne bacteria, molds, and viruses in one pass. Ultraviolet germicidal irradiation (UVGI) technologies are being used as infection control devices, primarily in healthcare facilities. No standard exists, but the dose of UV and the airflow are critical to ensuring all contaminated air is treated. The UVGI process is mainly influenced by the microorganism population, the irradiation intensity, and the intimate exposure time to the lamps. This new technology enables the system to increase the intensity field or to improve the inactivation process, without adding more energy or increasing the output efficiency of the lamps.

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.
