We need a variety of cell that is transparent to wavelengths plants use, so they could be used above farmland and pasturage. Many plants could probably be grown under them in places where it would otherwise be too hot, maybe even needing less water.

I imagine different plants need multiple different wavelengths.

#15Surely a small stepper motor will still consistently win? I mean this is cool for fixed structures but overall finding some empty space and pointing the thing straight at the sun seems better.

#16Earlier quoted context omitted.
Most of the plants I know about are green, and rely on chlorophyll electrochemistry.
Don't they look green because they reflect most green wavelengths?
Conversion efficiency of the part they do use can't be more than a few percent, so they probably radiate in IR. Converting IR radiating from plants, as suggested in TFA, thus seems like a good idea.
