This project addresses dead batteries. Of all of the televisions in the world, how many have remotes? Of those remotes, how many require batteries? Of all of those batteries, how often do they need replacing? Then consider: what is the cost, financially and environmentally, of replacing those batteries?
This project solves these problems by providing a remote that does not require batteries and doesn't change how we already interact with our remotes; what is more, it capitalizes on our frustrated instinct to shake our non-responsive remote, hoping this will bring our remotes back to life.
Rather than choosing an existing open hardware license I am electing to the maximum extent possible to refuse ownership and make no attempt to enforce any rights or privileges that may exist for this design. Information should be free!
While I commend your ingenuity and get the whole shake the control thing I have to wonder if hand crank flashlights would be a better model to work with. I suspect that the hand cranks are significantly more efficient at converting physical effort into milliamps and that the mechanism would also be more compact.
