scott,

walt pyle, who i used to live down the street from, is
an expert on all things solar & hydrogen.  he has
designed hydrogen space heaters, barbecue grills, and
stove burners.  he's done r&d on fuel cell technology
for some of the biggies, and even conducts experiments
with a "solar hydrogen reactor".  he's teaching a
class for solar energy international at the end of
may.  all of his contact info can be found on his
website at
