‘Hourglass Lamps’ Use Energy Of Falling Sand To Light Up

Brooklyn-based design studio Danielle Trofe has announced a series of lighting fixtures that uses the energy of falling sand to light up.
The ‘Sand & Solar’ series of LED lamps look like hourglasses.
When users flip the lamps to get the sand moving, Sand & Solar would harness the power of the falling sand to power the LEDs—making it possible for it to be a finite source of energy with minimal environmental impact.
