About Hollow Flashlight

Light by the heat of the hand

Winner of the Google Science Fair, Canadian Ann Makosinski, 15, has developed a flashlight that works through the only body heat.
Based on the Peletier effect, a phenomenon discovered in 1834 by French physicist same name, his flashlight, called Hollow Flashight can stay on for up to 20 minutes with the temperature difference between the palm of the hand and the air… even better than the lamp ball that we had you spoken here! For a description of the process by Ann (English), click here.

After the closing ceremony that has distinguished the winner of the 15-16 age category has agreed to answer our questions.

-How Did you found out you? One of my teachers advised me to apply. I had never heard of the Google Science Fair before. I was lucky that it speaks to me. And I did well to follow his advice…

-What Does it feel when you are selected as a finalist? I was very excited and very nervous to represent Canada. I think I was a little overwhelmed by a flood of Canadian pride … -Towards what studies or directed what trade are you? Surely to science, although I do not know yet exactly why. Maybe in the field of energy management…

-What Will become your lamp Hollow Flashlight? First I will try to improve its design and power and strive to distribute to those who need it most.

-Penses You that there are other applications for the human body heat? Haha! Of course! Seriously, I think that there is a real potential for medical sensors such as hearing aids or ECG electrodes. I also think of how, for example, to use the heat of the hand to operate or recharge a mobile phone…

On WholesaleAbly.com, Ann agreed to answer questions from users about flashlight:

Since when are you interested in science?
I am interested from a young age. In fact my first toy was a box of electronic transistors. My parents have always supported this interest. I collected everything and anything around the house and realized assemblies using a glue gun, creating many inventions that did not work. I think the idea of creating things and ask “WHY? “In me since birth. I’ve always been curious about how things worked.

-What Do you think is the best invention of the century?
Ooh, the best invention of the century? How to choose? I think of some examples of brilliant inventions, commme that of penicillin or alternating current (actually it’s more of a discovery), and so many others. I’m not sure of the best invention of the century by being against.

To whom will you just distribute this flashlight?
I would love that my flashlight is found widely distributed, but my priority would it reaches the hands of those who really need it, like children in the country in process development for example.

-Have You ever been proposals to extend your project?
Yes, I received marks of interest of several companies. But if other manufacturers are interested, they call me! haha;
