A group of scientists from the University of the New South Quay has designed a working prototype of a “night battery”, which in a technical plane is the exact opposite of facades. It uses the same principle of the PN junction in semiconductors, but it works in a branch node. The technology is called the “thermoradiation diode”.
The concept of such a battery was created back in 2014 and is based on the fact that the entire space around us is permeated with energy flows in various forms that can be intercepted. For example, during the day, sunlight hugs the surface of the earth, but not only bobs. And at night, this excess heat rushes into the cold of space, which gives rise to infrasracula meaning It is believed that we collect the energy of our star
Thermal radiation diodes later in solar panel and night vision details. O can intercept infrared radiation from a source, but it is freely energized. This efficiency is still not too high: at a temperature difference of 12.5℃, the power value reaches 2.26 mW, or 1.8% of the power of the highest voltage.
However, the display calculations that the power of the “night” battery may well reach up to 10% of the parameters of a solar panel operating in the same area and in the same weather. More importantly, the infrared sound signal can be any heated object, such as a car engine or a hot wall in a manufacturing plant. Even the human body radiates heat, often in vain, so it is possible to design some kind of clothing that will collect this energy and recharge a small part of the energy. gadgets.
