As much as one fifth of the world may not have regular access to electricity but 16-year-old Ann Makosinski of Victoria, Canada may have helped solve part of the problem; she created a flashlight that is powered solely from hand heat.
Using peltier tiles, which produce an electrical current when opposite sides are heated and cooled at the same time, she fashioned a light source that doesn’t use batteries, solar power or wind energy and entered it in the local science fair. It looks like a hollow aluminum tube and its core cools the sides of the peltier tiles attached to the flashlight’s cylinder while the other side is warmed by heat from a hand gripping the flashlight. As long as you hold it, it stays lit
How smart must those kids in Victoria be? She only took second place in the competition.
