I love this idea a lot! It is exciting to see opportunities for distributed wind. One overarching thought I have is about the use of the power generated by the tree. You mention it could be used for music/speakers, which seems like a non-essential activity in a community (fun and interesting but non-essential). I wonder if there's a way to refine this idea so that it can have even greater community impact. Perhaps the tree could provide electricity for street lamps, or feed back into a community center, or as you mention elsewhere, be used for cell phone charging. I think that if you could increase the focus on an existing community needs, it would strengthen the project.
You mention crowd-sourcing as an option to build out the financing options. Could you form an official partnership with one of these organizations?
