Frictionless generator for a bicycle? Answered
Right now I have a 12 volt 5 amp Werker lead acid battery powering lights, cell chargers, gps, and a few other gadgets. When I go on long trips I take the batter charger with me to charge the battery with a wall charger. The wall charger is heavy and unnecessary if i could find a way to harness the power I generate when I pedal.
i have seen plenty of generators which generate electricity by physically touching a dynamo to the tire but there must be a way to do it inductively, with no friction. What if I covered the wheel with hard drive magnets and ran them all past a coil on the frame? I know magnets going past coils will make electricity but not about rectifiers and capacitors and etc. How could I make this?
