Would you have a "plant power" roof, if it could help offset your power costs somewhat?
I have a solar-PV roof; it's probably cheaper overall than a "plant power" roof. Especially since we live in a climate where it would take a LOT of water to keep it healthy in the summer.
True, true - I imagine this would be highly climate-specific. I wonder though... if this could be done with garden vegetables... could you perhaps have a vegetable garden on your roof and collect power on the side... though they say it works best with rice-paddy style setups... hm...
