Maxismax rated 5 months ago- clever idea

- This is a pretty freaking awesome idea. As long as it's not difficult or awkward to raise the weight.

- From the page: "Clay Moulton of Springfield, Va., who received his master s of science degree last year from Virginia Tech, created the lamp as a part of his master s thesis. The LED lamp, named Gravia, is an acrylic column a little more than 4 feet high. The entire column glows when activated by electricity generated by the slow, silent fall of a mass that spins a rotor. The light output of 600-800 lumens lasts about four hours. To turn on the lamp, the user moves weights from the bottom to the top of the lamp and into a mass sled near the top. The sled begins its gentle glide down and, within a few seconds, the LEDs are illuminated. It s more complicated than flipping a switch, said Moulton, but can be an acceptable, even enjoyable routine, like winding a beautiful clock or making good coffee. "
