Article Summary
April 29, 2005 The hydrogen economy is looming, and it seems a weekly occurance to see additional announcements of technology adding to the momentum. This week from Penn State University comes the news of an electrically-assisted microbial fuel cell (MFC) that does not require oxygen and uses bacteria to coax four times as much hydrogen directly out of biomass than can be generated typically by fermentation alone.
