In recent days, one from the United Kingdom engineer team, developed a technique called "gravity lamp," the new device. The devices work like a pulley, just 12 kilos of stuff on a rope was tied, and then hung up, led lights can be on the other end. Due to gravity, the weight slowly settling on the floor, the potential energy is transformed into kinetic energy, kinetic energy lights up led drive sprocket. When heavy objects falling on the floor, the lights also went out, simply repeat this process, you can get continuous lighting. Every generation can provide lighting for 20 minutes to 30 minutes, the length of time decided by the weight height above the floor of the.
