Whatever you want to think, an R&D subsidiary of IAV Gmbh developed a
small, lightweight steam engine, using modern technology throughout,
that could be fitted into motor vehicles, although they see the
initial application as being in auxiliary power units, particularly in
third world countries. They claim fuel efficiency as being similar to
a diesel engine. It uses catalytic heating to avoid flames, which
keeps emissions down to very low levels, and can burn a very wide
range of fuels. Steam is viable, even if that does not sit well with
your world view.

As I hinted at before, where is the condenser and how big does it have
to be?


You would have to ask the developers that. However, they have said that
the engine could be fitted into a car, so they obviously don't think it
is a serious problem.

The only successful steam condensers for increasing pressure differencewere fitted to locomotives in Siberia for Winter running.

Others have been fitted to try to reduce water needed to be carried.
But have little effect on efficiency.

It's just not possible to reject that amount of heat on mobile steam engines
