A lamp lit by gravity? Patent pending...
Virginia Tech student Clay Moulton has created a lamp that produces the equivalent of a 40-watt bulb over a period of 4 hours, making use of LED lighting and gravity.
Using similar ideas found in the old-school grandfather clock, a user slides a weight approximately every 4 hours to produce a soft glow. Estimated to function for 200 years, this may be the next wave of green products.
Past innovations have been all about convenience, all about making things as easy as possible on the user (think about the innovation of the remote control). This is a step in the other direction, a manual-intervention device that is aimed at the 'greener good'.
The light, pictured at left, stands about 4' tall, and glows through the entire column, by diffusing 10 high-output LED lights.
This design was just awarded 2nd place at the Greener Gadget Conference.
