PUYL: Pump Your Light

PUYL: Pump Your Light

Check out this cook green gadget: the PUYL is a combination bicycle pump and portable light. But the simply clever part is that the light's battery is charged as you pump…

According to designer, Kai Malte Roever, the power is generated by moving the compressor/magnet through the two copper coils that are located around the inner compression tube. The generated energy is stored in a rechargeable battery/super cap.

The light source is an ultra bright LED bulb and the magnetic recharge method allows the LED light to be recharged unlimited times. Additionally, for every 20 seconds of pumping there is enough power generated for 45 minutes of light.

The PUYL won the Eurobike Industry Award 2009, which required that submitted objects be eco-friendly and reduce the number of items the user had to carry around. Unfortunately the PUYL is not yet available to purchase, but the idea is great and we hope someone puts into full production! In the meantime check out Roever's website for more great designs.
