Any basic physics text should cover it.

Electric and steam were both better for simple transmissions with good acceleration; ICE won on range and convenience.
Thermodynamic efficiency doesn't apply to electric motors. Steam is less efficient, which is why we don't have a whole lot of steam locomotives and ships these days.

Stirlings and turbines are OK to use up waste heat from ICE, if there's enough to pay for them.
Nope. That's why the development of the turbo-compounding aircraft engine was dropped: it turned out to be more efficient just to run the turbine, and leave off the IC engine. It's also why you see a lot of gas turbines used for power generation, but very few diesels.
