Hi Jason, All!

Yep. That's the point. To make ammonia takes hydrogen, nitrogen,
heat (a few hundred C) and high pressure (a few hundred atm) plus a
fast flow rate to whip the ammonia out to somewhere cool before it has
time to decompose. If you do it the other way round, ammonia, low
pressure (1 atm) high temperature (spark, thousands of C) no flow
rate, then the ammonia will fall apart and give nitrogen and hydrogen
:-) The **reverse** of the Haber process.

Or a triggered gap. Marc has done some excellent stuff with his

looks like it may be cheap and easy to build if you're not into
machining G10 composite or modifying motors.
