Things i know:
1. boyle’s law vaguely as; as pressure rises so does temperature.
2.Peltier devices can extract electricity given a large enough temperature differential, are there devices that do this better?
3. Heat pumps can pull heat from cold air on one side and make hot air on the other side.
I know i am missing some major steps here and ifs something ive always wondered about…

I think you mean “pressure law” for the P1/T1=P2/T2 equation. And I mean, yes an engine that uses heat to create pressure and kinetic force exists, check out Stirling engines. You basically heat up one end of the cylinder and cool the other end with a moving valve/rod in the middle to harvest kinetic energy off the repeated expansion and compression of fluids based on changing temperatures as you manipulate the position of liquids. They’re actually more energy efficient compared to combustion engines so some people consider them as the future, but as for now they just simply don’t generate enough force to be considered useful.
