Most of us are aware of the physical phenomenon of a thermoelectric device that creates a temperature difference when voltage is applied to its opposite sides. Coversly voltage is created when there is a different temperature on each side. This effect can be used to generate electricity, measure temperature or change the temperature of objects. The idea has been applied to develop an ingenious device that is a must-have for a modern-day survival kit. It will not only come handy when you are out there in the wild, but also a practical solution for storms and power outages to keep you and your loved ones in touch.
The device captures heat from campfires, grills, stoves, or any other source. Just place the metal heat catcher into the heat source, pour water into the small container. The heat transfers to the generator, water keeps the opposite surface of the generator cool, and the temperature difference generates electricity. The FlameStower works in most environments and all times of the day, unlike solar chargers. It generates 2.5 Watts of usable electricity for your phone, GPS and other USB charging devices. The unit folds conveniently into a backpack if you are going camping and it will cost you only $89.99.
