haha -- you should have put more effort into focusing on solar energy before I sold "photon" ;)

But at least you do get it: what area are you focusing on now? If you go too narrow (e.g. "local fruit cooperatives using people's back yards"), I think you may run into finding one group in Toledo, Ohio and another in Johannesburg, South Africa (or something like that). How would you deal with that?

Note that general search engine results on such topical searches are abysmal: see e.g. local fruit cooperatives (contrast that with a search for good fruit -- which also happens to be in the top 0.00004% of the results for local fruit cooperatives).
