Teenager invents [$38] solar panel that could be solution to developing world's energy needs ... made from human hair http://apocadocs.com/s.pl?1252532638
A new type of solar panel using human hair could provide the world with cheap, green electricity, believes its teenage inventor.
Milan Karki, 18, who comes from a village in rural Nepal, believes he has found the solution to the developing world's energy needs.
The young inventor says hair is easy to use as a conductor in solar panels and could revolutionise renewable energy.
The hair replaces silicon, a pricey component typically used in solar panels, and means the panels can be produced at a low cost for those with no access to power, he explained....
Melanin, a pigment that gives hair its colour, is light sensitive and also acts as a type of conductor. Because hair is far cheaper than silicon the appliance is less costly....
The solar panel can charge a mobile phone or a pack of batteries capable of providing light all evening.
