Milan Karki, an 18-year-old from Nepal, may have solved the world’s increasing energy problems, by inventing a solar panel that uses human hair instead of expensive wiring.

The young Nepalese, together with 4 classmates, has been trying to come up with a way of producing cheap, renewable energy for his home village ever since he went to school in Kathmandu, but now he dreams of powering up the whole world with his invention.

Milan has discovered hair not only makes us look good, but is also light sensitive and a great energy conductor, because of the melanin it contains. So he replaced the silicon in normal solar panels with human hair and thus invented a new type of solar panel, four times cheaper than the ones on the market today.

The inventor says he has already sent out a couple of his prototypes to districts in Nepal, to be tested for feasibility, but is confident he has found an answer to his country’s energy issues. He says buying half a kilo of human hair is not only cheaper than a set of batteries, but also produces energy for much longer period of time. And anyone can replace the hair, so the solar panel doesn’t require a lot of servicing.
