Fifteen-year-old inventor Ann Makosinski, a tenth grader from Victoria, British Columbia, has created a thermoelectric LED flashlight powered by body heat – simply hold the flashlight in your hand until it starts to glow. She used aluminum pipe and PVC pipe to create the prototype you see above. Continue reading for a video and more information.
The parts that went into the flashlight cost a mere $26, but if Makosinski manages to win the grand prize in the science fair she’d walk away with a $50,000 scholarship. It’s certainly an impressive feat for a fifteen-year-old, particularly if you remember back to what you were doing at that age. Inventing a revolutionary new gadget? Probably not.
