Ann, a Grade 10 student, took second place overall at the Vancouver Island Science Fair with her project, the hollow flashlight, which runs on the heat from a human hand. She will be bringing the unique design to the Canada-Wide Science Fair in May.
Watch the video below to see Ann explain her amazing invention.
Update 28 June, 2013: Ann won gold at the National Science Fair in Lethbridge with her project as well as the Energy Challenge Award and prizes to boot. She has been selected as a finalist – and the only representative from Canada in the Google Science Fair 2013!
In order for the flashlight to be powered by body energy, Ann used Peltier tiles – a device that produces energy when one side is heated and another side is cooled. Apparently, the light can last for about 20 minutes.
