Solar panels from human hair
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.
First I wanted to provide electricity for my home, then my village. Now I am thinking for the whole world,’ said Milan, who attends school in the capital, Kathmandu.
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.</em>
Excellent.
