The Sterling Cycle engine is not known to have any power/torque, but better the heat source better the power you had.
Winnabago(?) offered a Sterling powered gen. in their RV's back in the late '60's but it was very expensive for the day, so it failed.
The Swedish Army was playing with a small Sterling powered gen. to power a small field radio years ago and I think they pulled that one off. I don't know what happed to it.
I read about all this in some US military publications that a friend had.I think his wife tossed them after his death in 1990.
I still say that the Freon engine is the answer . US invention ,sold to the Izuzu in Japan after it was offered to the Big-3 who laughed at it in the'60's
This engine needed no fire, just a small electric Cal-Rod to power up.
It was just an A/C unit in reverse. Check the expansion rate of R-12 or R-134 when heated up. Its tremendous. The early on problem was the size of the needed condenser. The last I heard was the Japs were testing the engine in boats where they could use Keel condensers in the cold water.
The US inventor was running a prototype engine in a VW Type-2 so he could use the whole roof to mount the big condenser. He stated that he would have to recharge the system every two or three years at that time.
By the way, The engine was a highly modified 1909 White 2 cylinder steam car engine. The crankshaft was the rear axle . Lots of torque at low RPM's.
I wish I had a lot of money.
