A Nepalese teenager had made a £ 23 solar panel (太阳能电池板 ) using human hair.
Milan Karki, who is 18 years old and lives in a village, used human hair to replace (代替)silicon, which is a common but expensive part of solar panels. By using hair as a replacement, Karki says that solar panels can be produced for around £ 23.
Karki got the idea from a Stephen Hawking book, which explained how to create energy from hair. The device (设备) that Karki has showed can produce 18w of energy -- plenty to charge a mobile phone.
"Half a kilo of hair can be bought for only 16p in Nepal and last a few months; but a pack of batteries (电池) would cost 50p and last a few nights," according to The Daily Mail.
The solar panel is easy to service as the hair is easy to replace. Karki has now sent out several devices to other places near his home for testing. He said, "First I wanted to provide energy for my home, then my village. Now I am thinking for the whole world."

Whenever there's a terrible storm, there are plenty of sad stories. Many people lost their houses, their cars and their pets. But sometimes these stories have happy endings too.
A family in New Jersey, US, had a cat named Vivien. She is very smart. She could even draw with her wet paws on the floor. They all love her very much. When hurricane (飓风) Sandy hit America in October, they moved to a safer place-13km away from home. Sadly Vivien went missing. The whole family were worried about her. They put up posters on the Internet to look for her. All the nine family members searched wherever they thought she could stay, but they didn't find it. The family thought Vivien was gone forever.
But six months later, Vivien showed up at their house, according to Yahoo News. They considered her return as a wonder. No one can be sure where Vivien was for all that time.
Many animals are good at finding their way home. People usually say that dogs and cats find their way home through using their sense of smell.
But that doesn't explain how Vivien found her way back. Hurricane Sandy blew away the normal smells of home.
"I wish she could talk," said her owner.
