Rhett Butler tag:news.mongabay.com,2005:Article/2853 2008-03-05T14:30:39Z 2008-12-29T06:48:34Z Executives from General Motors Corp. and Toyota Motor cast doubts yesterday about the viability of hydrogen fuel cells for mass-market production in the near term, reports The Wall Street Journal. The executives said electric cars will be a better way to cut emissions and improve fuel efficiency.

Rhett Butler tag:news.mongabay.com,2005:Article/790 2006-03-06T15:19:39Z 2008-12-29T06:42:38Z Chemists at UCLA and the University of Michigan report an advance toward the goal of cars that run on hydrogen rather than gasoline. While the U.S. Department of Energy estimates that practical hydrogen fuel will require concentrations of at least 6.5 percent, the chemists have achieved concentrations of 7.5 percent. Rhett Butler
