One interesting engine is a thermo-acoustic engine. It is very simple in structure.
It`s a bit like the Stirling engine: Gas is expanding and shrinking, but cycle is faster.
Could perhaps say the engine is sound resonance engine.
Thermoacoustic engines can be divided into standing wave and travelling wave devices.
Efficiency is ca.0,1-0,4.
The origin is the so-called Rijke-tube in1859. The inventor was Pieter Rijke.
