Tourists traditionally spin a multitude of prayer wheels in Tibet. Now that 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. This invention supplements an inadequate and unreliable electrical grid with the power of electricity generated by tourism. By combining the low-cost efficiency and long life of 21st century LED lighting, with the simple 20th century efficiency of a bicycle, the Prayer Wheel Generator uses the best of high and low technologies.
