Some of the coolest inventions coming out today are ones that utilize alternative forms of energy. Kinetic chargers, desktop solar plug-ins, and now, soil powered lamps. It’s really more of a soil-powered battery that’s connected to a light bulb, but it is still incredibly cool. It uses metals found in the soil (like zinc, copper, and iron) to conduct with zinc and copper plates to provide a constant stream of energy. As long as the battery or lamp gets a bit of water once in a while, it can power the lightbulb forever. Maybe one day we’ll need to remember to water our plants, as well as our appliances.
