Know what would be really cool? Heated gloves and socks that get their energy from a hub, but the power is transmitted inductively (no wires to get tangled in). Induction sites would be the grips and/or the pedals. Anyone want to do up a schematic and determine current draw requirements? Heck, if the draw is too much, then you could have an intermediary battery buffer. It's a *huge* money maker.
