Study Shows Stability And Utility Of Floating Wind Turbines

Fri, 30 Jul 2010 14:30:48 -0700

College Park MD (SPX) Jul 06, 2010
Wind turbines may be one of the best renewable energy solutions, but as turbines get larger they also get noisier, become more of an eyesore, and require increasingly larger expanses of land. One solution: ocean-based wind turbines. While offshore turbines already have been constructed, they've traditionally been situated in shallow waters, where the tower extends directly into the seabed.

New super bacterium doubles hydrogen gas production

Wed, 14 Apr 2010 17:00:00 -0700

Hydrogen gas is today used primarily for manufacturing chemicals, but a bright future is predicted for it as a vehicle fuel in combination with fuel cells. In order to produce hydrogen gas in a way that is climate neutral, bacteria are added to forestry or household waste, using a method similar to biogas production. One problem with this production method is that hydrogen exchange is low, i.e. the raw materials generate little hydrogen gas. Researchers have studied a newly discovered bacterium that produces twice as much hydrogen gas as the bacteria currently used. The results show how, when and why the bacterium can perform its excellent work and increase the possibilities of competitive biological production of hydrogen gas.
