Abstract:
A process for recharging batteries which comprises:(a) coupling a dynamo to the intermediate hub of a stationary bicycle, which bicycle also has a front axle to which is mounted a front wheel, a front derailleur, and an interconnected crank and set of pedals attached in conventional fashion, said front derailleur being operatively connected to said intermediate hub; said dynamo comprising a housing having a fixed wheel containing a series of spaced periphery mounted magnets, and a rotatable wheel also having a similar series of periphery mounted magnets in close proximity, wherein said coupling of said dynamo is between the rotatable wheel and said intermediate hub, whereby pedaling of the stationary bicycle causes the intermediate hub to rotate, and simultaneously said dynamo's rotatable wheel to rotate due its connection to the front derailleur, and to produce a current, (b) conducting said current generated between the fixed and rotatable rear wheel, to a battery charger having one or more batteries therein, (c) charging the one or more batteries with said charger.
