Windowfarms

R&D-I-Y is a web platform for mass collaboration. Together, their community is working to integrate personal scale innovation for environmental stewardship + quality of life into the existing infrastructure of cities. They are applying open source software development techniques to physical systems development. They are developing hydroponic systems, LEDs, solar, aquaponics, sensor systems, nutrient sources and alternative energy . . . all using open source techniques and as many readily-available materials as possible.
The platform is currently being developed, building on their alpha project, Windowfarms.
