Most engines are less than 30% efficient at producing movement. The majority of the energy is lost as heat.

Thermodynamics tells us that pretty much all energy ends up as heat. In a closed system, any device that uses energy is 100% efficient at making heat. A 1000W computer will make exactly as much heat as a 1000W heater.

A 100% efficient engine can only exist if the desired output is heat, thus making it a pretty useless engine. Also, in a closed system, the exhaust cannot leave.

All space heaters should be coin miners (or some other borderline useless energy wasting tech, like AI training). Change my mind.

If you want to be philanthropic, there are programs you can run that use your computer's idle time to process data for cancer research and such.
