A very cool idea

Kinetic Prayer Wheels Transform Prayers Into Energy

Every year millions of tourists and locals descend upon Tibet's temples and spin the prayer wheels contained inside. If the mechanical energy generated by the movement of these spinning wheels could be harnessed, we could potentially reduce the size of our current carbon footprint and supplement an inadequate and unreliable electrical grid for numerous individuals. The Prayer Wheel Energy Generator, designed by Taikkun Yang Li does just this by transforming all of those good vibes into electricity that could be used to provide reliable energy for daily needs such as evening lighting.
