I always wanted to start an Open Source Cubic Meter project, where the intent was to grow as much food or perhaps absorb as much carbon as possible in a surface-level cubic meter. My concept would use Google SketchUp to sketch them, and hopefully university funding to test. There would be climate and/or terrain specific versions developed by the community, and the results could be multiplied the world over. Maybe I should try again or maybe it’s already happening somewhere online? =)
p.s. How about an open source cubic meter project for generating independent sustainable power?
