Google Science Fair Finalist Invents Peltier-Powered Flashlight 170

GTRacer writes "Ann Makosinski, a Canadian student competing in Google's Science Fair, submitted a flashlight which uses temperature differentials to power its LEDs. Her long-time interest is alternative energy because, '[she's] really interested in harvesting surplus energy, energy that surrounds but we never really use.' Using Peltier tiles and custom circuitry, her design currently runs for 20 minutes or so and costs $26. A win at the September finals in Mountain View and/or outside investment could fund further development."
