Why would it have to be a compact car?

I remember talking to some old-technology ship turbine operator who spoke of bubbling the expended turbine gases through the condensed liquid in a sealed system, thus causing rapid (almost violent) condensation, and not just a low pressure side, but an actual negative pressure on the low side of the turbine.
The condensed liquid was then pumped back into the "boiler" for reheating.
Of course in a closed system, other coolants/refrigerants/propellants would likely be superior to water.

It wouldn’t HAVE to be a compact car. But if you consider a $7000 e-cat which only delivers ~15hp, unless you are going for the > $60,000 car market, you’re looking at limiting your car to about 60hp.
If the design is a hybrid, with an oversize ultracapacitor to give you good 0-60 accelleration, 60hp could probably be enough.
It isn’t enough to produce a car that has near-zero fuel costs, if the car costs more than an equivalent gas-powered car and 150,000 miles of fuel.
