Remember the building urinal we talked about designed by Miguel Melgarejo? This time he outdid himself with this energy generating toilet paper holder lamp.

As its name implies, its both a toilet paper holder and a lamp. So what was he thinking when he designed this? Possibly harnessing wasted energy at home to supplement our everyday energy needs. The spinning motion of the tp roll will generate electricity to power the lamp. 

Very useful in the event of a black out don't you think?
