That's great LED flashlight exposure using hand power generation

Many people have such an unpleasant experience: when you need to find a flashlight flashlight, but can not find the battery to light it, without the aid of the battery if the flashlight light then this problem can be solved very well.

Recently, a 15 year old girl Ann Makosinskiy from Canada (AnnMakosinski) invented a energy-saving flashlight, light without the use of battery.

The flashlight using thermoelectric effects, through the hands of the user and the environment temperature heat to generate electricity. Scientists suspect that the human body can produce enough heat to maintain the power of the flashlight, the girl's latest design of the flashlight does not use all of the body's heat, only the palm of the heat.

The use of LED lights make this flashlight easier, she measured the palm heat produces approximately 57 MW of power, maintain the LED lights need power of about 0.5 MW, release light flashlight is very soft, but enough to find your keys or light the book page.
