It might seem like something science fiction but in reality at the base of this technology there is a basic principle of physics: that of thermoelectricity. There are different types of energy to be able to recharge any type of device, be it a smartphone or a car. Tesla for example it is famous all over the world for the production of electric cars; then there are magazines or power banks that run on solar energy. And it seems that a technology is coming from China that allows us to recharge a mobile device with hot water.
This hot water cup is a portable power bank and charges your smartphone via thermoelectric energy
A search for the China Academy of Launch Vehicle Technology demonstrated how it is possible to make a jug of hot water one source of energy to be able to recharge a mobile device. There are several multipurpose objects in the world: this time we are talking about a thermos, a container that keeps hot water at temperature and from which it creates energy to power a smartphone. In what thermos the device in question is quite compact and can keep the heat up to 6 hours above 65 ° C. But how does it work?
In the part of the lid placed inside there is a thermoelectric sensor that uses the heat of the water to create electricity. Clearly, you shouldn't expect an amount of power to fully charge a smartphone. According to reports from Sheng Jiang, one of the researchers:
One bottle can provide 20 to 30 minutes of electricity after pouring 300 to 500 milliliters of boiling water into it

How will a smartphone be rechargeable using this technology? Seeing the video, the prototype that was created in the laboratory predicts this thermos equipped with a USB output. Through this we can connect our smartphone to the device and charging will start as if we connect it to the mains. Undoubtedly a revolutionary device that lays the foundations for sustainable charging.
However, years will pass before this technology takes hold and works properly.
