Cheap Solar Panels Made from Human Hair

human hair generate electricityMilan Karki, a young inventor who comes from a village in rural Nepal, has created a new type of solar panel made from human hair, which could provide the world with green and cheap electricity.

The teenage inventor believes he has found the solution to combat world’s energy crisis. “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 new solar panel generate about 9 V (18 W) of green energy and costs around £23 to make from raw materials, being much more cheaper when it will be mass-produced. According to the inventor this solar panel can charge a pack of batteries capable of providing light all evening or a mobile phone.

The secret to this amazing low-cost solar panel is that the teenager has replaced the expensive silicon normally used in solar cells with human hair. He declared that human hair due to the presence of Melanin acts as a type of conductor, being in the same time sensitive to light.

    This is a complete hoax. Hair is an insulator; see . Melanin does have some semiconductor properties as described here but it isn’t possible to use human hair as shown to generate electricity. I personally did some experiments and confirmed this.

    Using Human hair to replace silicon is a good idea. If independent tests prove othewise, we can think of treating hair to develop such properties. Bulk treatment of human hair (or any other animal hair) should be attempted even if there is a glimmer of hope. Normally anything available in large quantity in nature is of great use to life – water and air for example. From this premise, we should start our exploration.

    Ananth: we should try it if it makes economic and ecological sense. Please see:

    It’s hard to believe. But Craig’s experiments don’t prove that it’s impossible. All they prove is that Craig didn’t manage to replicate the reported results.

    I hope more people try this. All we need is one more person to succeed.

    @Alistair Hi, Alistair. My intent with that experiment wasn’t to show whether Milan’s solar panel wouldn’t work, just to invalidate his claims (from his direct quotes) that hair conducted electricity and that hair would generate electricity when exposed to sunlight. The results I got merely back up what the scientific literature says. Also, there are many *other* problems with this design based on what’s publicly available. For example, as the rest of my analysis shows, it appears that the designers themselves didn’t understand their own invention. At the same time I wrote my article, other science sites also quickly debunked this claim. As it stands, the only thing that will validate this work is a patent or published research results that *can* be replicated independently. For now, based on what we know, I and others who’ve analyzed the claims are sure this is a hoax. You should also note that, at the bottom of my article, I suggest some research directions Milan can take and offer him my help… just so it’s clear that I’m not trying to trash the young man.
