It's not a practical design or anything, but I just feel like it's necessary to congratulate people when they wade this far into the sea of peculiarity. This particular device was created by Damon Vander Lind and it's come in ranked quite high at the Popular Mechanics DIY fair. Apparently he got the idea while working on a home-made wind turbine (admittedly a more practical persuit) and the entire rig cost him about $500 (and three weeks) to build.
