Whoever said playing in the dirt was bad apparently never met Dutch designer Marieke Staps. Staps has built a lamp that will run indefinitely on the power of mud.
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. Lord knows we have enough dirt to go around — might as well use it for something. Via Marieke Staps
