Sounds like magic: scientists have created a paper battery that works on water

Scientists at the Swiss Federal Laboratory of Material Science and Technology have created a unique, environmentally friendly and fully biodegradable power source based on the most conventional paper.

Moreover, energy is generated by using the usual water again, a few drops of liquid sufficient to feed an electronic clock for several hours, and the principle of innovation is generally similar to that used in traditional AA and AAA-forms.

They take one piece of paper on which a layer of graphite cereal is applied and the other one is impregnated with cooked salt. Under the influence of water, these sheets begin to interact, resulting in electrical current. Of course, the new battery test samples obtained so far are still too small, but scientists promise that they will be able to produce results comparable to conventional AA elements. Meanwhile, a decent smartphone of the middle class Oppo K10 Vitality Edition was introduced, and wireless headphones of Anker Soundcore Life Note E arrived in Russia.
