ANN MAKOSINSKI

摘要

Ann Makosinski's first serious toy was a box of transistors. She's been tinkering ever since, creating projects with a hot-gtue gun and household items, A few years ago, she used her hobby to solve a real-world problem. A friend in the Philippines mentioned she was failing school; without electricity, she couldn't do her homework at night. So Makosinski devised a flashlight powered by the heat of your hand. It uses pettier tiles, which generate electricity when one side is hotter than the other, to draw energy from the heat difference between hand and air. Makosinski submitted her invention to the 2013 Google Science Fair and won first place in her age group.
