What if we harvest that heat for energy

    That is exactly what we are doing in the upper end of that efficiency range (turbochargers, turbine generators, heater cores) - the waste heat from that is unharvestable (exhaust gas, engine core heat).

    Yea, combined cycle gas turbine power plants are pushing above 60% efficiency. They use the waste heat from the turbine exhaust to generate steam and then extract energy from there. About as good as it gets.

    Cars could be a lot better if emissions wasn't a concern.
