Gravity-powered Energy" The idea of using the force of gravity to generate power has been around for some time.
As far back as the 1970s, for instance, scientists were discussing the theoretical possibility of tapping into the gravitational pull of black holes to generate power [source: Time]. The idea was that if matter could be fired at a black hole from a safe distance (so the firing device wouldn't be sucked in), the extreme squeezing of that matter by the hole's gravity would make it hot enough to start a fusion reaction.
The Gravia lamp relies on a much simpler concept: Gravity pulls objects downward. The lamp is a standing floor lamp, 58 inches (147 centimeters) tall and cylinder-shaped. Inside the cylinder, there are several basic parts involved in creating light: brass weights, a ball screw, a drive gear, a rotor, generator and a bunch of LEDs.
