Re. blades: you can just cut them out of a plastic plumbing pipe diagonally, therefore you get cheap blades that can be easily replaced in overwind accident.
Hi, I write for Popular Mechanics and I'm working on a story about Thingiverse and 3D printing scientific equipment, in which I am going to mention this lovely turbine. Could I call or email you to get your comment on this device in particular and the practice of open source hardware sharing in general? My number is 212-649-2973 and my email is [email protected]
