Power Generating Shoe

While this DIY water turbine shoe may not be going on sale in stores anytime soon, it is still pretty cool (and after all it is a homemade DIY project... what would you expect). Whenever you step down water is forced through a miniature water turbine which then goes through a tube that goes back into the sole of the shoe. This version of the shoe may not be practical for everyday usage, but if the hardware was all packed into the bottom it may actually be a good way to get "free energy".
