Surge of light / Green energy Light

In Tibetan, devout believers, who hold prayer wheels in their hands, can be seen everywhere. They often go to the temple and touch the wheels there so that they rotate. Thousands of visitors rush to Tibet to look for rotating the prayer wheels and hope the wheels will bring them godliness and propitiousness.
Tibet is short of electricity. The public night lighting for the temple is caused by the mechanical energy that is produced by the combination of the prayer wheels and electrical generator.
