Apparently no longer a conventional flashlight and battery manufacturers will lose their customers. Because've found a flashlight that can be lit only by body heat, which is generated by the palm of the hand alone. Makosinski creator is Ann, 15 years old girl who is still in junior high school Victoria, British Columbia, Canada.
The idea is really talented. He realizes that the warmth generated by the human body is the source of energy is negligible. When he thinks creating a flashlight for science projects, ideas about the human body's energy continues to boggle the brain. How do you transfer energy into a flashlight?

The goal is reached when he discovered type of tile known as Peltier tiles - tiles can generate electricity when one side of the tile is heated and the other cooled. Ann Makosinski thought, if he could make the tiles form a hollow in it, this means that he can hold the flashlight on the outside of the tile to heat the inside, while the ambient air will cool down tiles on the inside of the flashlight.
Unfortunately, the power generated by the Peltier tile is not strong enough to cause electrical voltage. To solve the problem, Ann Makosinski create a circuit as the transformer, to produce and raise the voltage in the device flashlight.

Scientific projects were managed successfully. He has successfully created a human body heat powered flashlight. According to Dailymail, Ann Makosinski production costs flashlight is quite expensive compared to conventional flashlights, for U.S. $ 26. But definitely no more costs incurred subsequently to the battery. So much more efficient and environmentally friendly, is not it?
