 You may not need to worry about batteries someday soon. A 15-year old girl, Ann Makosinski from Victoria, British Columbia, Canada has invented a flashlight that uses the heat from your hand for power.


 
Instead of using batteries the flashlight uses Peltier tiles 2. Peltier tiles produce electricity when one side of the tile 1 is heated and the other is cooled. In her first attempts she was able to produce enough power, but not enough voltage 3. But eventually she was able to find a solution and produce a working flashlight.
 
Makosinki was able to build the flashlight for under 30 dollars. And considering you will never need to buy batteries, it’s a great deal.
 
She is currently 4 one of 15 finalists in the Google Science Fair. The grand prize is $50,000 dollars and a trip to the Galapagos Islands. The final round will be held in Mountain View, California this September.
