A Nepalese inventor believes he has found the solution to the World’s energy needs thanks to a new type of solar panel which uses human hair.

Milan Karki, 18, comes from a rural village in Nepal. The young inventor uses hair as a conductor in solar panels instead of silicon, one of the normal components used in solar panels. Silicon is very pricey whereas hair is not therefore the new solar panels are a lot more cost effective.
