I was just curious (and perhaps this has been addressed already) but.. I think it would be helpful to have a section called something like "The Renewable Man" which has areas on Green Projects, suggestions, tips, and so on. The forum is a way to archive this content, and you never know when someone will simply pop on and drop a piece of gold. :)
Solar - Great Balls Of Fire
Wind - Gaia'a Breath Don't Stink
Biofuels - MOOP into Megawatts!
Batteries/Storage - That ain't heavy, that's my battery
Recycling/Reusing/Composting/etc - Do it AGAIN!
and so on :-)
Or however the org might take place. It might be important enough, and able enough to generate content that is not directly related to BM, that it could merit even more attention.
