Google Science Fair Finalist Invents Peltier-Powered Flashlight

Posted by Soulskill on from the now-make-a-peltier-powered-bicycle-and-you've-got-an-investor dept.

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."

    So if you're hanging around the desert and the ambient temp is warmer than your hand, will it make things darker? That would be cool.

    Wait a minute.

    She just invented a new flashlight, and wants to use "energy that surrounds but we never really use."

    Like, the energy that surrounds us and penetrates us, and binds the galaxy together? Her "long time interest" is clearly building a light saber.
