Ann Makosinski Invents Hand Heat Powered Flashlight

15-year-old Ann Makosinski is an teenage inventor who has created a flashlight powered by the heat of your own hands!Ann Makosinski

Ann entered her idea in the Google Science Fair, an online science competition for 13 to 18-year-olds from all around the world.

Her invention was so great she was chosen as a finalist in the fair, and now has a chance to win a $50,000 grand prize scholarship, plus a trip to the Galapagos Islands.

She calls the flashlight a "hollow flashlight," and it utilizes a sepcial technology called Peltier tiles.

Peltier tiles make energy when one side of the tile is being heated while the other side is cooled. With a little bit of experimentation, she was able to use this energy to power an LED light.

Best of all, Ann only spent $26 on all of the supplies necessary to build the special flashlight. She said that if they are ever mass-produced, they could be made for even cheaper.

We wish Ann Makosinski the best of luck this September when the prize ceremony will be held and the winners will be announced!
