A student created a lamp that uses gravity to generate enough power to light multiple LEDs to give off the same lumens as a standard incandescent bulb for four hours. cool stuff!

We are seeking for one Gravity powered light for one science center. May we have your quotation with delivery up to Hong Kong.

Great idea.
Is there a pointer to info about this? I assume one turns the unit over creating potential energy, and gravity moves an element to generate the power – until it reaches “bottom”.
