Something wrong here. Heat engines are limited by the heat sink temperature and the high temperature. Typical efficiency is around 20%. They are claiming 60% which seems to break the laws of physics.
By the term Heat Engines, does this include Stirling engines that you can buy or make miniature working models of?
“Something wrong here. Heat engines are limited by the heat sink temperature and the high temperature.”
I thought the efficiency of a piston engine was more-or-less a function of the compression ratio. That’s why diesels are more efficient than gas engines.
Diesels get around knock by squirting in the fuel near top dead center rather than having it come in mixed with air during the intake stroke.
Des the use of hydrogen/argon permit a greater compression ratio?
Tell me where I’m inaccurate here which I probably am.

Diesel engine are in the 45 to 55% range. If the combustion temperature is higher for hydrogen, the efficiency would be higher.
