Gravity lights

About 1.5 billion people in the world have to light with kerosene lamps, both fire and environmentally friendly.

Recent research from the University of California, Berkeley and Illinois, states that kerosene lamps are more harmful to the environment than we think. In an alternate effort, the team invented an LED called GravityLigh t. The energy provided to the lamp is free as it is available throughout the planet, which is gravity.

Below the lamp is a 9kg sand or gravel bag, hung by a pulley system. Bring the sandbag close to the lamp then let go. The sandbag will slowly drift slowly to provide energy to the lights for 30 minutes. Then repeat the operation. The light bulb is also designed for use with other devices that connect to it like radios, rechargeable batteries with ports on the front. The brightness of the lamp is also adjusted to increase the operating time.

According to Gizmag, the team hopes to gain access to funding to purchase production tools and materials to make 1,000 GravityLight lights. It will be sold in Africa and India to poor households for under $ 5.
