Wii Energy Conversion

  If you've ever played Wii Sport, you'd know that a lot of kinetic energy is wasted while playing this game. If energy converting devices can be made into the remote (maybe make the whole thing a bit longer to fit the device in), then the remote can convert the kinetic energy into electrical energy. This can be linked to a dry cell holder where the cells can be charged directly from the remote. And this can also be appliable for other Wii games, though those games must involve a lot of movement. Imagine all these while playing Wii!
