Charging your phone while biking to work could be a very useful form of multitasking, and Royal College of Art graduate Offer Canfi is working to make that possible.
His project, called Flux, turns bicycles into mobile generators. It uses resonant inductive coupling to wirelessly charge devices, and demonstrates a possible method for charging electric bicycles through inductive bike lanes.
Inductive charging has been demonstrated before; you can even buy inductive-charging pads for your car. However, Flux’s method of charging a phone or bike on the move is fairly novel.
A fully-deployed Flux charging system would use emitter coils embedded in the road surface. Current would be transferred through these coils the relatively short distance to similar coils in a bicycle’s battery pack, or the batteries of a laptop or phone in the rider’s backpack.
It will probably be expensive to lay the inductive bike lanes, but at least the infrastructure to transmit electricity already exists in urban areas. It would also eliminate the need for lots of cords.
