Concept illustrations of Gravia depict an acrylic column a little over four feet high. The entire column glows when activated. The electricity is generated by the slow fall of a mass that spins a rotor. The resulting energy powers 10 high-output LEDs that fire into the acrylic lens, creating a diffuse light. The operation is silent and the housing is elegant and cord free -- completely independent of electrical infrastructure.
The light output will be 600-800 lumens - roughly equal to a 40-watt incandescent bulb over a period of four hours.
To "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. An hour glass-like mechanism is turned over and the weights are placed in the mass sled near the top of the lamp. The sled begins its gentle glide back down and, within a few seconds, the LEDs come on and light the lamp.
More information is available here and here.
Just a spot where I can put up game ideas, technology, theories, and other misc items that come up.
