Bacteria-driven cell produces hydrogen for fuel while cleaning wastewater
By harnessing the efforts of billions of bacteria, researchers have engineered a bio-filtration system that produces hydrogen gas while cleaning wastewater – gas that could potentially fuel other machines. Up to 100 percent more efficient at producing hydrogen than similar bio-filtration systems, the new device has the added benefit of being able to digest human or animal waste, plant material or just about any organic matter.
Hong Liu and Bruce Logan of Penn State University and Stephen Grot of Ion Power, Inc. of New Castle, Del. announced their findings online April 22, 2005, in the journal Environmental Science and Technology.
