My impression from doing the story is that they want to use the farm for experiments in living. Trying out solar, wind, raising animals, growing with intensive raised beds, etc. But I don't think they expect to be completely self-sufficient, in the short-term anyway. I think they're fairly realistic that their entire community isn't set up that way at this point (good points about what it takes to supply solar, wind, etc). Tim, the farm's owner, is also trying experiments in more sustainable city living (for more, I did a video on his small town green highrise going up in Chapel Hill, NC http://faircompanies.com/videos/view/a-small-town-green-high...
