"Hollow Flashlight": 15-year old student builds totally battery free, body-heat-powered flashlight!
September 12, 2013, 4:17 pm
Ann Makosinski, is a 15-year-old student from British Columbia. The girl is still in high school but managed to design a flashlight that could signal the end of batteries, as we know them today!
Makosinski`s flashlight is powered entirely by body heat, and to be presice, specifically, heat produced from the palms of the human body hands.
The device, which Makosinski calls "hollow flashlight," uses Peltier tiles to transform hand warmth into usable energy, all and battery-free of course! A typical light beam on the "hollow flashlight" can last up to 20 minutes once it`s produced.
Ann Makosinski`s flashlight will be brought to the Google Science Fair on Sept. 21, where it will compete with the projects of 14 other students, all hand-selected from across the planet. The winner will receive a $50,000 scholarship and a free trip to the Galapagos Islands.
The "hollow flashlight" project seems quite revolutionary and if developed further, it could, for example, transform the constant rising temperature of the planet into energy and in general it could change the way we use, and buy, energy across the globe.
