Flashlight Powered By Body Heat

How many times have you cursed your flashlight because the batteries were dead? How many times have you been in the dark after only a few minutes of light? The young Canadian Ann Makosinski has solved the problem by inventing a flashlight that works thanks to the warmth of the hand.

Better not be refrigerated if you want to use this flashlight. Designed by Ann Makosinski, a 15-year-old and winner of the Google Science Fair, the “lamp Creuse” (Hollow Flashlight) is used without batteries! His only source of food is so your hands and, above all, their heat. Reloading by body heat

Reloading by body heat Ann Makosinski has prepared his flashlight using tiles Peltier. These components can produce electricity when they are heated on one side while the other side remains cold. The flashlight LED glows so as soon as the body heat tiles. Meanwhile, the air circulating in this lamp hollow is in charge of the other side of the components to cool. The difference in temperature between the two sides then produces enough power to generate light. So just the user to simply hold the lamp in his hand. According to his, Ann Makosinski would chose to use human energy when she discovered that “we are living 100-watt bulbs”.

Deal with a universal problem

The girl explains that she found the idea of his flashlight on the Internet while she was doing research on the rmoelectric generators. “I think that the Internet is a great database and that there is so much information available. For me, people do not quite”, she adds, taken over by CTVNews “. But, above all, Ann Makosinski said that his inspiration came a friend in the Philippines. The latter had dropped out of school because she could no longer work as soon as it was dark. The Canadian had then decided to find a way to produce light without battery or electricity: “she was my inspiration for the project, but so many people in the world have the same problem”.

Other applications?

According to her, his invention could perfectly be placed under the seats of a classroom to inform school, in medical wireless devices or even to charge smartphones and other portable electronic devices. “I think there is a real potential for emergency equipment, medical kits.” This invention can also be useful for people without access to electricity or light”, details the winner.”
