Eco Factor: Bicycle light gets powered by electromagnetic induction.
Designed by industrial designer Kai Malte Roever, the PUYL is a bicycle pump that doubles as a permanent illuminating bicycle light that doesn’t need a battery to operate. The patent-pending device consists of a normal bicycle pump, which in this case charges a built-in battery using electromagnetic induction.
Electricity is generated by the system when the user inflates a flat tire with the pump. The motion of the pump causes a magnet to move between two copper coils. Electricity generated by the system is stored in the battery which then is used by an ultra-bright LED bulb.
