Bacterial boost for clean energy

Joseph Miceli, a researcher at ASU's Biodesign Institute, studies specialized microorganisms known as anode respiring bacteria (ARB). Rather than investigating their role in health and disease however, his research explores the ability of these microbes to clean up waste and produce useful energy in the form of electricity or hydrogen.

'Waste heat' may economize CO2 capture (w/video)

In some of the first results from a federally funded initiative to find new ways of capturing carbon dioxide (CO2) from coal-fired power plants, Rice University scientists have found that CO2 can be removed more economically using 'waste' heat - low-grade steam that cannot be used to produce electricity.

A marine animal to feed your eco-car

The marine animal tunicate can be used both as biofuel and fish food, according to research from Norway. On the ocean floor, under the pier, and on ship ropes -- that's where the tunicates live. Tunicates are marine filter feeders that serve as bacteria eaters and as a foodstuff in Korea and Japan. But in the future they may become more prevalent.
