It's an interesting idea. I will be keen to see how it develops. The
downside will be that you have to fill your car with water as well as
petrol, unless he includes a condenser to recover the water from the
exhaust gases.

Be easy enough to rig up some kind of bifurcated fueling nozzle with two
adjacent orifices on the car. If it can really run that cool, imagine
the advances in aero design with no need for a massive airflow over the
motor or radiator.

It is a brilliant idea, so simple in the concept. Keeping the water
liquid in a Minnesota winter might be tricky, but a small heater in a
short run tank, and the exhaust pipe through the main tank, and building
in a way to freeze/thaw without damage (elastic tank & hoses?) might get
there.
