Algae as a High-Temperature Hydrogen Source

A team of researchers from the University of Tennessee, Knoxville and Oak Ridge National Laboratory have found that the inner machinery of photosynthesis can be isolated from certain algae and, when coupled with a platinum catalyst, is able to produce a steady supply of hydrogen when exposed to light.

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.

EPA's National TV Recycling Challenge

Electronic Manufacturers Recycling Management Company (MRM) is the winner of EPA's National TV Recycling Challenge. MRM developed a TV collection network that uses a variety of collection approaches, including establishing collection points with charities and self-storage units, to recycle approximately 3 million pounds of TVs.

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.

Is technology making people too self-absorbed?

This week’s question concerns the impact technology is having on society. Technology has made it possible for people to share every aspect of their lives - both the good and the bad – with the entire world. The insatiable desire of some people to reach out and touch each other has made Web sites like Twitter, Facebook, MySpace and YouTube phenomenally successful. Now a UK-based company called Vicon is developing a small camera, called the ViconRevue, that can be worn around the neck and automatically take pictures every 30 seconds, virtually documenting every moment of your life. The pendant-size camera, which was originally designed to help Alzheimer’s patients, can store about 30,000 images on a 1GB memory card and should be in stores next year. Fans of the concept think it’s the coolest tech-toy since the camera phone, while critics call it proof-positive that society as a whole is becoming too self-absorbed. What do you think? Is technology making people too self-absorbed?

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.
