For those of us who have been looking for power generation without much noise, this is very similar to a linear Generator that NASA has developed for power on remote bodies (E.g. Moon/Mars).
They have coupled the power production to a Stirling Engine cycle. Heat is derived from decaying plutonium (which, if memory serves, about 700F degrees.
I went down this path trying to use the water heater on propane to drive the Stirling cycle, and use the water heater tank as a heat sink - as well as to heat the RV.
I eventually gave up because the BTU to watts conversion was too poor compared to a standard generator. Also the prototype was noisy - as noisy as a inverter generator.
It was an interesting exercise though and I learned a lot in terms of mechanical engineering and thermodynamics.
if you Google NASA Linear alternator or NASA Stirling power you'll find the link to the NASA site where they discuss at great lengths power production on remote bodies. None of the linear generators need oil - they use a spring and diaphragm design on linear bearings.
