We’ve seen a slew of solar-powered lamps in the last couple years but this is the very first time “dirt”, (yes, the stuff that’s on your ground) has been used to power a lamp. We wonder how long this will go, specifically when it will be available to the consumers.
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
