This Thermos Uses Hot Water to Charge Your Phone
The Beijing Institute of Space Vehicle Systems Engineering of the Rocket Academy has designed a hot mug that doubles as a power bank using the thermal energy from the hot liquid in the mug. According to the researchers they have made this possible by using aerospace technology.
The mug uses the heat from the liquid and charges your smartphone directly. In other words, pouring hot liquid in the mug will charge your phone. The researchers believe that as smartphones become more common in the modern world, power banks have become even more essential as well. Hence, a gadget like this helps you stay hydrated and charges your phone at the same time.
