Electric motors are in general, a lot more efficient that internal combustion engines. An average combustion engine has about 18â20%. A formula one engine, has about 50% of an efficiency.
If a solenoid engine compares to a piston one, the standard rotating electrical engine compares to a turbine. Differences in complexity are evident. And efficiency of a solenoid engine is low, while ordinary electric engines are the most efficient engines I know of. A solenoid engine is a mechanical curiosity that, somehow, manages to work.
