Gravity Lamp - Gravia Floor Lamp by Clay Moulton
The floor lamp powered by gravity has arrived. Gravia Floor Lamp has won the 2nd prize at the Greener Gadgets Design Competition 2008 held in New York City. In order to "turn on" the lamp, the user moves weights from the bottom to the top of the lamp. That's it. The creator of the lamp Clay Moulton estimates that Gravia's mechanisms will last more than 200 years, if used 8 hours a day, 365 days a year. Fascinating. As far as I know, you can't buy a Gravia yet. I don't think it's going to take too long to start the mass production though.
