Franz asked "..... Why not mount windmills directly on every car? ....."

Why bother when most cars have their alternators doing nothing most of their
journey, they could be used to charge up a 2nd battery, If you think of how
much potential electricity could be produced each day from our traffic, cars
and lories etc, it would add up to a lot, and with no extra fuel used.
Alternatively, make all vehicles petrol/electricity combined so that the
electricity produced would go to power the car in urban situations, thus
saving fuel and co2 emissions.
Also.What about a microwave powered engine.
