Electrons are suspiciously close to spinning dynamos, so even just moving electrons might be considered spinning something.

Kolanaki@yiffit.net 4 days agoIt’s all variations of “make things spin.”
Either by heating up water so steam makes thing spin, using wind to make thing spin, or moving water to make thing spin.
The only kind of energy conversion I can think of that doesn’t make thing spin is an ICE. It makes thing go up and down with boom, which in turn makes something spin.

Nope, solar cells are solid state devices. ;)

except for the fact that you actually want a grid tied interia component for stability.
So even in that case, you still tangentially need a “spinning mass” even if emulated in software with how it supplies energy to the grid. It’s still technically there.

Have you considered supercapacitors could be used for that?

Honestly the easier way to switch from solar DC to grid AC is to just have a flywheel between the grid and the solar power plant. It might not be as efficient as a capacitor bank or super capacitor bank but it’s dead simple to implement and it’s extremely reliable.

that’s still just inertia though…
Now just using the complicated AC coupling of DC energy, through complex electronics…
All when you could just, big motor with massive mass spinny real fast like, and then when the mass starts spinning the motor, it makes power.
Mechanically, it’s probably both cheaper, and more cost effective to just use a flywheel, which is literally going to be an inertial system.
