Hmmmmm, maybe if I had a 1500hp monster truck.....

I was reading that, at least, propane could be used to replace the AC
refrigerant. http://en.wikipedia.org/wiki/Propane
and there was an interesting gas-absorption refridgerator with no moving
parts that can cool directly from heat energy.

It's an open secret propane works fine in R12 systems with only minor
tweaking of the TXV-in fact, under most circumstances, even without
it. Thousands of vehicles are driving around with propane in the AC
system, cooling fine, in fact as we speak, usually unbeknownst to the
owners.

Two problems: the "heavy ends" and fuel additives in most propane will
foul things up eventually, unless reagent grade propane is used. More
significantly: if the evaporator, particularly, or really any part of
the system leaks...especially the evaporator, because the fumes will
get into the interior..when (not if) it hits a spark, you will have an
explosion. If it's inside the sealed car, the occupants will probably
blow up like VC in the tunnels of Vietnam when the ethane gas was
injected by Special Forces. The only reason strict laws were never
passed against it is because they figured it would only publicize the
practice, and more people would do it. Other than that propane makes a
fine refrigerant.

Servel was the main maker of gas fridges, but now there is a bounty on
them. Their lives are in danger. Save the Servels!

'Reagent' propane, that would be the odorless stuff.... :)
