One question I have had on my mind is about solar powered LED lighting.
Solar cells capture a wider spectrum than plants (plants are green ergo not green eaters).
At what levels of efficiency do solar cells and LEDs have to be before you receive a net gain by having the solar cells in the sun instead of the plants. How far away from that are we now?
Underground farming in arid regions seems like the best scope for something like this.
