Human powered generator:
Made this from my spare car parts. alternator and bicycle both have some bearing noise, but overall, it comes together to make a very good human powered generator. only cost me 15 bucks, but if you had nothing, this could easily be built for under 100. similar models for purchase are over 300 bucks.
