This is An Electrifying Invention This new invention is called a shadow-effect energy generator. It's the stuff of science fiction but it's real. The device produces a current from the differences between bright light and shadowy areas. The bigger the contrast in light the more energy it produces. The device can produce enough energy to power a small electronic device like an electronic watch. The materials scientist inventor - Swee Ching Tan of the National University of Singapore - says this allows us to "harvest energy anyplace on Earth."
Shadows of Value The new device is similar to a solar cell. Tan created the generator by placing a thin coat of gold over silicon. Light shining on the silicon energizes its electrons. With the gold layer, the generator produces a current when part of the device is in shadow.
