Karen we sat at dinner here in vacation at an eco house in panama on the ocean and talked of your idea- 5 houses up, 5 houses down. All love it. Simplicity!! Comments were: yes, trust is paramount-with no fiscal benefits going to home owners, some icon on Facebook for homeowners as they bring in the 10 neighbors so friends can cheer them on, liked your potluck idea where all 10 come at once. Then brainstormed getting word out there. The annual National Solar Tour in our area is big. All owners r anxious to spread the word and open their houses- usually in mid October. Maybe tour goers could each be invited to 5up and 5down bringing them to a friendly owners home - to bring to scale more quickly. Also how can we utilize connections with Solar Decathlon? Bet there's a way to leverage that. - Considering "Tell me and I'll forget. Show me and I'll rember. Engage me and I'll understand" ...wonder how the potluck could have paper and pens so guests could draw collectors on sketches of their houses or what is some little thing they can do that's beyond show and tell? - Giving kudos to the community that grows together instead of individuals. I see some challenge where the winning classroom received tickets to the 2014 Solar Decathlon in France last year which of course is expensive and overkill here but certainly in line goals. Well - sorry no ideas to further the project at this stage of the game.. What u have is great. I can talk after Sunday if that would be of service. My best wishes!!!! Darr Notes: The ASES National Solar Tour is the largest grassroots solar event in the nation, involving about 150,000 participants and 5,000 solar-energy sites nationwide.
