Par example... where the HELL did sgort get the idea that H2 is the most powerful fuel ever? Seventh grade chemistry tells us the oxyacetylene torch can yield 3480 °C, while oxyhydrogen only 2200 °C. Practical experiments on Brainiac also show acetylene to clearly be a better explosive.
And as I've said a few times before, I've seen a dozen "carbide cannons" made from drain PVC that held up the pressure, but eventually got contorted because of the heat.
2. What the hell does combustion pressure have to do with anything? It refferes to the pressure at which the gas spontaneously detonates, so unless you plan on containing H2 at 500 PSI inside a tank without porous material inside you're pretty safe. Containing H2 is an issue of its own.
So in a nutshell, H2 is probably more powerful. But you'll have to generate it on the go, since it's difficult to contain.
Propane is pretty inexpensive and easily available. I use butane because it's even more available.
because, he was obviously refering to a combustion so i was givveng him an idea of the pressure that it generates.
