Prayer Wheel Energy Generator

" Tibetan designer Taikkun Li is using tourists as an energy source for his Prayer Wheel Energy Generator, envisioned for Tibet. This is how it works - when tourists spin a multitude of prayer wheels, the positive energy can be harvested along Tibetan streets, turned into electricity, and used to provide evening lighting along those streets and inside the adjacent homes.
The prayer wheel generator is built on a base of used bicycle parts and a discarded surplus fan motor, making it ideal for use in the developing world. Hence the combination of three elements - low-cost efficiency, LED lighting and the efficiency of a bicycle, the Prayer Wheel Generator is a perfect alternative for countries that is so beautiful to succumb to the global warming conditions."
