A light wind


Many alternative energies fall back on the elements. High in demand is wind.

For proof, look no further than a design student in Berlin. He has developed a lamppost powered by four rotor blades.

Tiny currents, created by passing cars or tunnels between buildings, are converted into electricity by a 300 watt generator.

Initial tests at an ideal height of 3-6 meters supplied around 12 volts, which can be stored in an integrated battery. Enough for an LED light.

Thanks to an infrared motion sensor the self-sufficient streetlight only switches on when someone passes underneath it.

The light points exclusively downwards and, measuring 2800 on the Kelvin scale, attracts almost no insects.

A good companion for blooming lights.
