That depends. If you want a heterogenous system, then you need to take the sum
of the inputs to determine the grams (or mililiters) to the number of joules
output. I'm assuming that a nanotech solution might be able to mix hererogenous
chemicals in a stable form until a trigger is given.

Oh? I thought the hydrogen-hydrogen bond was fairly week by chemical standards.
Is it just the sheer density of atomic hydrogen that you could get? If so,
having to dilute it with something else might be greatly detrimental to its

Interesting, but not really within the realm of chemical energy anymore.
