| I think we could solve two problems here. In france (If I remember correctly) they have exercise bikes linked to power generators, which can provide your house with however much energy you exert and is subsequently put into the machine. We have used similar things before, such as pump powered torches, watches that run off body heat, and various other things.
An alternative would be for a gaming console, similar to the wii, where characters of games brought out would have the physical abilities of the character. The success of it is debatable though.
