Inflation adjusted, gasoline prices were higher in the 80s. However, that's neither here nor there. I think world events are making this a more urgent issue. What I would like to know, if you can tell us, what is the actual available energy in a kg of liquid air used in a piston engine? Obviously, it could be a turbine engine as well, but how much energy do we get? By the way Keith, I can speak from personal experience that a 20 gallon LN2 spill is no big deal. Before I acquired cryo-pumps and turbomolecular pumps I use to use a lot of LN2 and I'm sorry to report I was quite careless with it. The only real danger in a confined space is that it can drive away all the available oxygen and you can pass out or die from oxygen deprivation. It's not unpleasant either. You're body's suffocation response is from build up of CO2 rather than lack of oxygen. I'd much rather that than than burning in a hydrogen fire. I don't know if liquid air has the same composition as gaseous air, but if it does, even that danger won't exist.
