But being blind and not wanting to hang of the back of a tandem, I still
think its a gooer. after all you can get useful battery charges from hand
cranked devices, it should be possible as i said originally to get a bit
more from pedalling and simply use it to charge up AA rechargeable for
example. At least all your energy does not go into warming up a friction
plate.
