Soil Lamp

Who knew soil could do more than just grow vegetables?  How much power does mud have? Well,  apparently enough to  power a lamp.  Seriously , a dutch designer named Marieke Staps did just that.
She took some soil, wet it a bit and voila! a small LED light bulb burns bright.

The soil is contained in cells , the zinc and copper in the soil acts as an electrolyte.
The power is carried up a thin conductor leading to a bare bulb.
An earth battery? Imagine the possibilities......

And it looks cool too
