A 15-year-old girl in B.C. invented a body heat-powered flashlight and won $25,000 in scholarships from Google.
"I chose to investigate the aspect of human energy when I found out that we are like walking 100-watt light bulbs. The goal of my project became a flashlight powered solely from the heat of the human hand," Ann Makosinski of Victoria said in her project description for this year's Google Science Fair.
The flashlight is made with Peltier tiles, which generate electricity when heated on one side and cooled on the other. Because Makosinski's flashlight is hollow, the inside is cooled by air while the outside is heated by the hand of the person holding it.
The teen won the 15-16 age category and earned the scholarship cash and a Lego trophy.
Makosinski, whose role models are scientists Nikola Tesla and Marie Curie, said she has a "great love for science."
"My family has encouraged my interest in the sciences, and my first toy was a box of transistors. I also have a great passion for insects, and I have a cat."
