A few years back, the aviation industry played around with an idea of =
'contaminating' their aviation fuel with a chemical that prevented it =
for burning. The chemical was removed just before it entered the actual =
engine. Now that must be one hell of a process when you think about the =
amount of fuel a jumbo's engine needs. Perhaps it would be possible to =
alter the chemical properties of the H2/O2 mix or add a 'dampening =
agent' to make it more stable (less likely to blow up in your face) but =
reverse the affects in the actual engine compartment on demand.
It's just a thought.

That's a good point, and one I respect. I'm quite
capable of handling hydrogen safely, as obviously
you are, but many others may not be. :o) I do remember
blowing up a number of apparati(!) in the late '70s
when I was experimenting with electrolysis cells
as a teenager. :o)

Compressing the oxy/hyd mixture is something I have
stayed away from, the thoughts of diesel effects etc
are very worrying. Dr. Brown's assertion was that the
gas mixture was extremely safe, providing temperature
was considered, and some of his more "reckless"
demonstrations were regarding the compression and
handling of the mixture using crude pumps, obviously
full of oils etc. Better him than us.

I'm surprised they aren't a heap of *really good*
oxy/hyd welders on the market, which is sad, but no
I don't expect to see many hydrogen powered vehicles
on the roads, at least not for some time.
