Solar photovoltaic is the only one i can think of that isn't just a fancy way to make steam

EDIT

ok let's clarify to say a method that isn't related to movement of a fluid that spins a turbine. So not windmills (air is a fluid), not hydro, not geothermal, etc.

All power generation is either solar or 'make thing spin', unless we're including RTGs and Piezoelectrics.

All of these are in some way heat engines

[–] herrvogel 5 points 7 months ago (1 children)

Yeah but those heat engines don't rely on spinning things inside a magnetic field. Heat on one side, less heat on the other side, and you have current. No motors.

even photovoltaics are heat engines in broad definition

[–] herrvogel 4 points 7 months ago

We're all heat engines on this blessed day if you broaden the definition enough.
