Jon, th e Hindenbeerg burned around the periphery of the hydrogen cloud. 
If it was mixed with air, like it would be in a closed car, it woul 
dhave exploded. ANd no, it does not have to be compressed.  And I did 
over state the lower explosive limit and th eupper limits. IMy memory 
was bad. It is more like 17% to 56 percent or some such. Never the less, 
turn it loos int he interior of a car and it certainly will explode if a 
spark source is present.
