Milan Karki, an 18 year old teenager from Nepal, thinks he has found the solution for the developing world’s energy needs. He has made a solar panel with hair as a conductor, making it one of the cheapest solar panel so far.

What started as an experiment could turn out to be a commercial viability for developing nations. The solar panel produces 9 V (18 W) of energy and costs around 23 ponds to make from raw materials. The teenager is convinced that when mass-produced, the solar panels could be sold for less than half of the price. Swapping the expensive silicon for the far cheaper hair is the main change that makes his solar panels so cheap. While the solar panel can only charge a mobile phone or shine a light all evening, for the developing nations this could be a great possibility to stop the power failures which occur almost every day.
