    Light Battery Charger

    Some one needs to design a generator connected to the BB rather than the wheels....to charge light batteries...

    With todays high flux magnets and only requiring 1.5 to 3 volts volts to drive the Leds, should be quite easy and light.

    Probably save quite a bit over trying to carry a 3 hour high power battery pack.

    Sure you will need a battery probably just a 1/2 hour pack.

    I've always had the same idea about stationary trainers. Why can't we get electricity from our exercise? Or a spin class at the gym may be able to power the lights and music for the room.

    The problem with a generator connected to the BB is getting the wires out of the frame and keeping them out of the crank. I love the idea, so I will have to put some thought into this.

    Why would you want it at the BB? At the wheel you are at least getting some free power on the downhill sections.
