Green award for ‘gravity lamp’:

Virginia Tech student has won Greener Gadget Award for creating a LED floor lamp,dubbed Gravia,that is powered by gravity.The lamp has won second place in the Greener Gadgets conference in New York City.Clay Moulton’s concept illustration of Gravia shows 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.
