I'm building a prototype of something ridiculously good. an airborne wind generator.
Google and ARPA-e built one with Makani Power for ~say$60M . it's crapo.
My proof of concept was £200 (good exchange rate eh?) prototype on the way for about £2k. It's going to kick the big corporate butt and it's free for you to try too, open source non-commercial licenced hardware. coolio.
Quite a bit of testing till I'm commercial but in the mean time...
