Boeing to fly fuel-cell GA plane...

I read an interesting article in the papers a while ago concerning hydrogen
fuel cells. It made the point that the fuel cell can actually be more
polluting than an petrol engine since all the hydrogen ejected into the
atmosphere could have an adverse effect on the oxygen in the air and
possibly lead to a decrease of global temperature...

The article was obviously written by a moron (or possibly misunderstood).
Engines that use fuel cells eject water. Simple chemistry. Two molecules
of hydrogen plus one of oxygen produce water (H2O) and a little energy
(can you say "Hindenburg"?).
