(PhysOrg.com) -- When a newly developed technology for producing hydrogen gas from biowaste is brought to commercial use - as researchers believe it can be - then it appears the world will have plenty of energy if it can just solve the stubborn shortage of sewage. http://www.physorg.com/news142702016.html Technology Wed, 08 Oct 2008 16:26:56 EST news142702016 Researchers have combined the efforts of two kinds of bacteria to produce hydrogen in a bioreactor, with the product from one providing food for the other. According to an article in the August issue of Microbiology Today, this technology has an added bonus: leftover enzymes can be used to scavenge precious metals from spent automotive catalysts to help make fuel cells that convert hydrogen into energy. http://www.physorg.com/news135482832.html Biology Thu, 17 Jul 2008 03:07:12 EST news135482832 A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers. http://www.physorg.com/news135349137.html Nanotechnology Tue, 15 Jul 2008 13:58:57 EST news135349137
