Steel can become soft at 1000F. I mention that because 60% efficiency on a 70F day requires a heat source of at least 900F. https://www.omnicalculator.com/phy

- willis936 5y agoIs that true for all steels? High speed steel can be have a significant amount of tungsten in it.

- tagoregrtst 5y agoThe walls dont have to be at 1000F. The gases in a piston engine are at > 1000F and the walls much cooler. This one reason why, in piston engines, larger pistons ate more efficient. Less heat loss through the walls
