Soil Lamp, a lamp that doesn’t need external electricity to light up. It is a lamp that completely runs on mud. It relies on the metabolism of biological life contained in the mud, to produce electricity that is sufficent to power up its LED bulb.
The soil lamp uses LED, which requires very low electricity to keep it lit up. The mud is enclosed ib various cells. These cells contain copper and zinc that conduct electricity. More cells will generate more electricity. The only hassle is you need to splash the lamp with some water every now and then.
