Microbial Fuel Cell  Researchers at Penn State, working in
cooperation with a scientist from Ion Power, Inc., have
developed a microbial fuel cell that can turn wastewater and
bacteria into hydrogen. According to Penn State, the new process
can get up to four times as much hydrogen straight out of the
biomass than what can typically be generated by fermentation
alone. But Bruce Logan, the co-inventor of the process (seen at
right), doesn't think he smells a solution to the world's energy
problems, saying that there's just not enough "waste biomass to
sustain a global hydrogen economy."  Apex AD-1250X supports
