Soil Powered Lamp: A Fresh Take on “Dirty Energy”

Soil  naturally contains energy conducive metals like zinc, copper and iron, and microbial fuel cells (sometimes referred to as an earth batteries ) are capable of converting electrolytes in soil into usable energy . Dutch designer Marieke Strap’s Soil Lamp  uses conductive plates made from copper and zinc buried within the soil to provide constant and (nearly) eternal light for an LED bulb . Maintaining a Soil Lamp is as simple as watering a plant – just feed it a splash of water every now and then to keep the energy flowing.
The Soil Lamp takes pride in its simplicity and innovation, baring all in a transparent bulbous base. The implications of creating energy  from soil are promising – as a free and abundant resource, nearly everyone in the world has access to dirt, save those living in deserts  or urban jungles . Because of its naturally occurring conductivity, soil is easily converted into energy that will last far beyond the lifetime of an incandescent bulb , so long and its properly watered.
