Pete, what is the energy density (per lb) of a Liquid Hydrogen system, on a scale that would fit in a motor vehicle? Not just the liquid H2 itself, but the kind of tank that would be necessary to consider driving around with it safely? Aside from the interesting idea of pulling up at the local filling station for a refill of 18K fluid.

An amusing aside on a vaguely related topic. You can use a mix of propane and butane as a drop-in replacement for R12 in older automotive air conditioners. It's dirt cheap, and I think it might actually be a more efficient refrigerant. However, the idea of having a couple pounds of LP gas equivalent circulating in the front of the car strikes terror, even though it would be pretty difficult to make a combustible mixture out of it. Do you think driving around with a tank of LiH would be more acceptable?

Cheers, Dan.
