A
15-year-old girl has invented a unique flashlight.
Don’t be surprised! It is powered only by the heat of your hand! Can’t
believe what I'm saying? Last year Ann Makosinski in Canada created
a flashlight that uses kinetic energy to power its
LED lights!
Makosinski already managed to secure a place in the finals
of the 2013 Google Science Fair. One day, Ann was interested in harvestingsurplus energy, energy that
surrounds us but that we never really use.
The
electrical power to light the bulb in the flashlight is generated
because the heat from a human hand is hotter than the air around it.
The light is strong enough to find small objects or read handwriting in the dark.
Everyone who has a normal body temperature can use it for about an
hour and a half.
The purpose
of the invention is to be eco-friendly and contribute
to protect the environment by making it unnecessary to have a battery
inside the flashlight.
The fair’s final winner will be announced on Sept. 23. If she becomes
the grand prize winner, she will receive tickets to fly to the Galapagos
Islands, as well as a $10,000 scholarship. Good luck, girl!
