Cost-effectiveness[edit source]
It is definitely possible. The question is: Is it cost-effective? That's obviously a context-dependent question, but consider that animal power was replaced by mechanical power based on fossil fuels, and now fossil fuel based electricity is being replaced by solar in small-scale remote contexts. I'd want to see figures for costs and conversion.
Of course it's possible that there could be technologies like FreePlay's which could be adapted to make animal power more cost-effective (presumably as just one of the outputs of the animal, with meat and milk). Interesting idea. --Chriswaterguy 06:27, 19 March 2011 (PDT)
