In the quest for eco-friendly gadgets and toys, we are seeing more and more designs that utilize kinetic energy. In addition to helping the planet, kinetic charging provides a convenient and free energy source: all you need is a few shakes, pulls or cranks in order to keep your gadgets juices flowing.
Trend Hunter has featured numerous kinetic energy innovations, from hamster powered paper shredders to breath powered USB chargers and kinetic energy PC keyboards.
First, let's introduce you to the Pullight Dynamo (see main picture), which works as both a flashlight and a charger for your other gadgets. Since very few current gadgets come with this special kinetic charging mechanism, designer Sebastien Sauvage did not want you to be left out: Simply pull the string of the Yo-Yo shaped dynamo to generate free energy. Besides string-pulling, the dynamo houses a 3 phase motor that generates additional power from any kind of movement. By the end of your jog/ run, you will have more than enough energy to charge up your iPod.
