Making energy from dirt
Living Power Systems has developed a commercial microbial fuel cell similar to the plant-powered fuel cell we told you about a fee weeks back. But the Living Power Systems fuel cell runs on dirt. Or rather, it generates electricity from bacteria in dirt.
If you think back to your third grad science class, you'll probably remember that you can generate electricity from a potato or other living material. But you generally get such a small amount of energy that it's not really worth the trouble to harvest it. Living Power Systems' technique is exciting because it actually makes dirt power usable. I'm not saying you'll be able to power your laptop computer with dirt anytime soon, but home lighting and cellphone chargers aren't out of the question.
