I twist, twirl, I want to charge
Yong Ken Hwan and Myung Ho Kang, inventors from South Korea, invented a battery for mobile gadgets and cameras that do not require an external source of energy for recharging.
Their battery is charged manually. It is the standard "finger" format AA, its body is composed of two parts. To charge the battery, it is enough to twist in opposite directions its two parts. This movement starts a spring placed in the battery case, it transfers the charge to the microgenerator, also hidden in the case, the generator recharges the battery cell - the same as in a regular battery.
The Swedish innovative company will soon put on sale a charger that works without electricity, but on the water, reports the Hi-news portal. The power source called PowerTrekk weighs only 175 grams. To recharge, for example, a cell phone or a navigator, you must connect it to a USB port, insert a cartridge into PowerTrekk and pour 15 milliliters of water. This is enough to get 4 watts of electricity.

Charge Battery is divided into two parts, and each half of the body for the convenience of the user is equipped with special bulges. As soon as the battery goes down, you need to rotate it several times along the axis - and it is ready to work again.
A spring is placed in the Charge Battery case, which, while stretching, drives the generator. The authors of the project claim that a few turns will be quite enough to extend the work of the flashlight for a few minutes, or to take a couple more shots with a camera.
So, now having appeared with the discharged battery, it will be enough to make several rotary movements and to extract a little pure energy. It remains to wait for the appearance of this gadget in Russia and hope that it will not have an exorbitant price.
