I would just LOVE to know where you get the idea that HEAT is converted into power? Even the piston engine has heat as a by product, requiring bulky cooling systems where as the pressure within the cylinder is required to push the thing around.
Heat is used in this case for gaseous expansion leading to velocity. Love to see your patents
Please expand your wisdom to explain to all of us poor lost uneducated souls how the Lappos engine works, I'd love to see it.
