John Malone and the Invention of Liquid-Based Engines

  It is apparently a form of Stirling engine: https://en.wikipedia.org/wiki/Malone_engine https://en.wikipedia.org/wiki/Malone_engine

    Thanks. So the liquid part is the working fluid. I had been wondering if the pistons were liquid; some engines like that have been built, but not very efficient ones as far as I know.

    I find it a bit funny. Robert Stirling invented the Stirling engine because steam engines were dangerous (at that time) and could explode. Malone(and others apparently) took Stirling engines and filled it with compressed water as a working fluid with some decent efficiency! The advantage, based on what I could gather from limited info available, was that these liquid engines could be run at lower temp differential making them great for low grade heat recovery.

    The entire website is amazing! It should be archived.
