How are they claiming 60% efficiency?

If you know jack about the second law of thermodynamics, you are familar with the theoretical Carnot cycle. It is the most efficency possible engine until somebody disproves the Second Law. The max efficiency on the Carnot cycle is 50%.

Anything beyond 50% is a scam.
