wastewater.jpgResearchers at Oregon State University have discovered an efficient way to produce hydrogen power using biowaste like municipal sewage. The innovative process uses 75% less energy than the traditional method of producing hydrogen, and can be done at a much lower cost.

The new approach could utilize several types of biowaste, including manure, wood waste, or sewage, to produce hydrogen at a much lower cost than the traditional “electrolysis” technology, making it attractive for use in hydrogen fuel cells that could power the non-polluting automobiles of the future.

Thanks to a genetic breakthrough, a large portion of Earth's now-inhospitable soil could be used to grow crops -- potentially alleviating one of the most pressing problems facing the planet's rapidly growing population. Scientists at the University of California, Riverside made plants tolerant of poisonous aluminum by tweaking a single gene. This may allow crops to thrive in the 40 to 50 percent of Earth's soils currently rendered toxic by the metal. (Wired Magazine online )

co2-scrubber-calgary.jpg University of Calgary climate change researchers say they are close to figuring out how to commercialize the capture of carbon dioxide directly from the air with a simple system that could be set up anywhere in the world.

If they can make it work, it would allow greenhouse gas to be removed from ambient air and reduce the effect of emissions from transportation sources such as cars and airplanes.
