Re: [GBlist] house thoughts to fuel cells



Fred and others,
  One perspective in your post caught my attention as needing some 
clarification.  You wrote

Your paragraph and other prose I have read in newspapers and other media 
makes fuel cells seem like a completely clean fuel source.  What you cannot 
ignore is the energy that goes into making the hydrogen.  Sure, it's a 
clean fuel source if you make hydrogen from solar or wind power.  In this 
case the fuel cell is just a better way to store energy than a battery, but 
it is not ultimately the energy source.  Currently most hydrogen is made 
from conventional electricity, I believe, so fuel cells are only as as 
eco-friendly as the source of the electricity.  On a side note, I fear that 
the Bush administration is capitalizing on the public perception that fuel 
cells are completely clean because there are no emmissions at the end use.

All the best,
