Solar is no doubt the coolest.
Hydro and wind are also very neat, going directly from mechanical to electric via generator, without a steam-turbine.
There is also a very cool fusion-category based on dynamic magnetic fields, that basically form a magnetic piston which expands directly due to the release of charged particles via fusion and then captures the energy from that moving electric field by slowing it back down and initiating the next compression.
A fully electric virtual piston engine in some sense, driven my fusion explosions and capturing straight into electricity.
Feels so much more modern than going highly advanced superconducting billion K fusion-reactor to heat to steam to turbine.
Wait, how can this possibly not involve a turbine? Maybe there's a semantics thing I'm missing or we disagree on, but what's turning the kinetic energy into rotational mechanical energy to spin the generator if not a turbine? Or are you saying the turbine is incorporated, as in a turbine generator?
Just so we're seeing the same picture:

Yeah, not the right words. I intended to say no steam turbine.
Instead of turning energy into heat into turbinable fluid flow in form of steam, they directly use turbinable fluid flow.
The difference is really the lack of steps up to the turbine.
Ahh gotcha, thanks for clarifying! And I agree, very cool stuff.
