It looked to me like the main thing the guy had invented
was a very efficient way to direct the hydrogen and oxygen
gasses.  As you say, done incorrectly, burning hydrogen
can have drastic results.  Just ask the Hindenberg passengers!
The video showed the tip of the torch as cool to the touch.
To do that you'd have to have the burning action happening
away from the end of the torch which could probably be done
by judicious direction of H2 and O streams so they combine
just in front of the tip.  Or at least that sounds about right. :-)

Thanks for the correction!   Interesting to see that
acetylene has been used as an "anesthetic". (I wonder
if they actually meant anesthesia?)  That would be
freaky!

Cheers,
