15 Year-Old Google Science Fair Finalist Impresses with Body-Heat Powered Flashlight
Ann Makosinski, a 10th-grader, is just one of 15 students from a global pool to find themselves in the finals. This certainly isn't her first entry, but it's getting a ton of traction. She stumbled upon Peltier tiles while investigating alternative energies years ago (yes, for real), and she went on to create a body-heat-powered flashlight. The total cost for the flashlight prototypes that she has built totals around $26, so mass production is well within sight.
So, what did you do again as a teenager? (Shouldn't we all be asking ourselves that?)
