Headlamp, powered by the heat of the human body

Makosinski Anna, a young inventor award-winning invention for thermoelectric flashlight, demonstrated a new version of his invention: headlamp flashlight powered by the heat of the human body.

16-year-old girl from the city of Victoria demonstrated a new device in the Ontario Science Centre in Toronto on Tuesday, where she received the 2014 Award for the concept of a flashlight.

Flashlight, which won a prize at the "Fair scientific achievements Google┬╗ (Google Science Fair) in 2013, as Headlight, charged by the so-called devices - Peltier. Peltier elements are capable of producing small amounts of electricity when heated, on the one hand, and cooling the other. Heating is provided by the heat of the palm, while cooling - with air passing through an aluminum tube.

Reward Weston award in the amount of $ 2, 000, established in 2008, is awarded annually to young Canadians who creatively use their scientific knowledge to change the world for the better. As for Makosinski, she hopes her invention will help people in developing countries, for example, friends in the Philippines, who first inspired her to create inventions.

"She told me how failed the exams at school because of the lack of electricity and as a result, the light could not teach lessons at night," -vspominaet Makovinski to interview with the correspondent of news CBC.

She added that such a device can be useful in emergency situations, as well as in terms of camping, because it requires the use of batteries.

The project to create forehead flashlight was quite ambitious, recalls Makosinski as it was necessary to create a design that would not be too heavy or bulky while wearing, as if he is about to fall on your head & quot ;.

Another challenge was to find a good enough battery as head emits a large amount of heat.

Characteristic features of this prototype are the batteries that are attached on both sides of the device, and an LED lamp that is on top of the length of the hull, like candy lollipop.

In the present invention has a solar panel to recharge and additional capacitor which allows to accumulate electricity without the use of batteries.
"The device requires only a turn, and it will produce light - the temperature of the flashlight when it does not matter," - commented Makosinski.

Under normal conditions, the device works best at low temperatures, as there is a large temperature difference between the head and the air, although Makosinski asserts that the difference may be only two or three degrees.

She added extra features flashlight, on the improvement of which it still works.

The girl said that several companies have already expressed interest in the manufacture of this product, but "they are waiting until the brightness of the flashlight yet become competitive compared with existing counterparts in the international market┬╗.

Makosinski hoped to be able to invest the money received from the recent award to obtain a patent for his invention.

However, she is glad to have the opportunity to showcase their inventions in the Ontario Science Centre.

"A lot of young people will be able to see the device and check their work and hopefully get inspiration┬╗.

Weston Youth Innovation Award was established by the Foundation W. Garfield Weston, a private Canadian family foundation. Earlier awards were awarded for such inventions as the device that made the solar panel to charge from the sun, and biofilters, which are capable of removing nanoparticles from wastewater.
