As an added bonus, they're based just down the road from me!
- pjc50 11y agoPiston efficiency is basically limited by leakage round the seals and friction on the bearings. Can be in the very high 90%s. The system efficiency is limited by Carnot cycle like everything else, I think; they are claiming 75% AC-AC round trip, which is impressive if true.
