It’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.

I am willing to bet if you watched photo cells on solar panels under a microscope, the light would make something spin.

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

Nope, solar cells are solid state devices. ;)

Other examples of solid state electronic devices are the microprocessor chip, LED lamp, solar cell, charge coupled device (CCD) image sensor used in cameras, and semiconductor laser.

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?
