Conventional cars operate at around 15% thermal efficiency. Tell us
about what 3000% efficiency might mean, please.
Of course we could reduce air drag and rolling resistance to some
degree, and we could accept operation at lower speeds for less drag. But
please tells us what you mean by "200 times more efficient."

I have been aware for
a long time that we can run the humble old combustion engine at rates
200
times more efficient than conventional running.
