flammability of hydrogen. This moves forward on the production
side of the issue. We still need to deal with how to store it
safely.  I have worked with cylinders of compressed hydrogen for
over 20 years in the lab and never had any problems. My college
professor made a perfect statement about using hydrogen as a
fuel for vehicles; if you rupture a hydrogen tank you release
the hydrogen and it rises, if it ignites you get a fireball
above the vehicle, if you rupture a tank of gasoline you release
the fuel and it makes a puddle under the vehicle, if it catches
fire, well your cooked.  If either explodes violently you are
dead either way. Precautions handling both are similar for
keeping things safe. Possibly the biggest worry with hydrogen is
that it is both invisible and odorless, which would make a leak
more difficult to find, but
