15 year old Ann Makosinsk from Victoria Canada has invented a flashlight that doesn’t need batteries and instead is powered by the warmth of our hands. She was researching alternative energy methods when she came across the 
Peltier tile, a tile which generates electricity when cool on one side and warm on the other. She did some calculations and discovered that the energy generated could be enough to power a flashlight. Ann did months of research on transformers and circuitry before coming up with a working prototype. She is a top 14 finalist at the Google Science Fair and is going onto the finals of the competition later this year.
