BULB GLOWS ON GRAVITY POWER

A British company has developed new gravity motor force to generate electricity on free of cost to light the Bulbs. The Gravity light uses a sack of sand to gradually pull a piece of rope through the dynamo mechanism which generate electricity power.

The company claim that a 3 seconds pull on the rope to sack of sand will keep the LED bulb running for up to 30 minutes. This  product will be marketed shortly by the company . This was invented by Martin Riddiford and Jim Reeves from London.
