Eco Factor: Bicycle light gets powered by electromagnetic induction.

Designed by industrial engineer Kai Malte Roever, a PUYL is a bicycle siphon that doubles as a permanent educational bicycle light that doesn’t need a battery to operate. The patent-pending device consists of a normal bicycle pump, that in this box charges a built-in battery regulating electromagnetic induction.

Electricity is generated by a complement when a user inflates a prosaic tire with a pump. The suit of a siphon causes a magnet to pierce in between dual copper coils. Electricity generated by a complement is stored in a battery that afterwards is used by an ultra-bright LED bulb.
