>Yes, I agree. In fact, I think that if as much time, effort, and money was
put into the development of a turbine engine (like the Chrysler one) as has
been put into the engines we currently run, the "200 MPG carb" type idea
would be a case of "so what!" In the case of the Chrysler turbine, it had a
very ingeneous heat transfer drvice that recycled otherwise wasted heat from
the exhaust to the intake, thereby making the engine more efficient (this is
a bit more difficult with the IC engine to say the least - basically, it has
to be stored as chemical potential energy within the fuel, and this can only
>be done by chemically altering the fuel with an endothermic reaction). The
problem that I can see with the heat exchanger is that it didn't exchange
enough of the exhaust heat. Obviously, if it exchanged more, with a greater
efficiency, the engine would be more efficient - it's basic thermodynamics,
and it's even given a name - "Regenerative cycle" ie. recycle waste heat

easiest

The most impressive moment I had around the Chy Turbine car
was standing behind it, and the ambient temp rising from 60-70F
to well over 100, very quickly.  Maybe an over impression of youth
but it made ya walk away in a hurrry.
