A 15-year-old high school student by the name of Ann Makosinski has invented a flashlight that draws power from the heat generated from the palms of your hands. Dubbed the “hollow flashlight,” it uses the Peltier effect (the same technology...

Better get a patent on that or Apple will steal it and sue you for using it.

A few months ago I saw a documentary about a Japanese scientist who spent about 10 years inventing and developing a heat-to-electricity technology. It's so exciting to see a young girl beat him in such a short period of time. She really gives a word "invention" a new meaning.

Just another invention that will never see the light of day.
The battery companies will buy up the patent and set on it.
Take a good look, it's the last you'll see of it.
 
Peltier tiles are nothing new, also considering how faint the light is from something like this there isn't much of a purpose for this aside from being used as a beacon. You'd have to charge a battery a lot in order to generate enough power to use for a flashlight or lamp even. In the phillipines this would be even harder to use considering how much harder it is to cool this with ambient air. This 'invention'(strapping a lamp to peltier tiles is not something fancy) isn't nearly as useful as using something like a hand powered dynamo to charge a battery to power a lamp.

Not entirely accurate. The peltier effect has been known about since the 90's and it's been used extensively in reverse to cool things. This isn't a new invention its just applying exiting tech in new ways

Im sorry but since when is Inventing something involve taking existing technologies and putting them together????? she didn't INVENT anything. how about I nail two boards together and call it a spoon??

uh, and you obviously didn't do your homework - The Peltier effect is the presence of heating or cooling at an electrified junction of two different conductors and is named for French physicist Jean Charles Athanase Peltier, who discovered it in 1834.

I wonder how much power could be generated during the insulting effects of homes, freezers, A/C ducts, and portable coolers.

What about the heat generated from automobiles versus the surrounding air? There is allot more potential to this than powering hand-held flashlights.

this tech is used in portable coolers. those that are plugged into your vehicle - http://www.coleman.com/Products/8570/thermoelectric-coolers

do you know how to do research??

Not when I know how to get you to do it for me. This way I can do research and get you to help me with other research I don't have time for. How was that for a smart *** reply to a smart *** question?
wow that was tricky. so intelligent..so you answer questions without knowing the answer. you must be a politician.
