2007 Virginia Tech graduate Clay Moulton recently won second place in the Greener Gadgets Design Competition in New York City for the Gravia gravity lamp. According to my dictionary gravity is defined as "The natural force of attraction between the earth and my penis that makes it drag on the ground when I walk."
The lamp's 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.
To activate the lamp you simply move the weights from the bottom to the top, where they start their 4 hour trip down the tube. The light output will be close to that of a 40-watt incandescent bulb and Moulton estimates the device could have a lifespan in excess of 200 years (with the LEDs being the first components to go). A patent is currently pending for the lamp, and I hope to see them on shelves soon. And you know what else I hope to see on shelves soon? Girlscout cookies. It's annoying how you have to wait for the scouts to come around selling them. I think I missed them this year. I need those things damnit. The wife is getting very bent out of shape without her thin mints. Shes says she'll kill me if I can't produce a box by the end of the week.
Thanks to Kathleen, who appreciates awesome green gadgets, for the tip
