The Dirt-Powered Lamp
by Brian Yalung on Friday, March 13th, 2009
We have seen various kinds of energy sources, but nothing like this new concept; a lamp that thrives on dirt. The soil lamp uses the chemical reaction between copper, zinc, and slightly moistened mud to create enough electrical current to power an LED lamp. More cells can be used to create a brighter light or power more bulbs.
Perhaps inspired by Tesla’s wireless energy, Staps might be on to something. If there’s enough energy in dirt to grow huge redwoods, why not power a tiny little bulb? No word on when or if the soil lamps will ever hit the market.
