At present, which is more promising, superconducting technology or wireless transmission technology?

Superconducting technology and wireless power transmission technology are very promising, and they are both valuable scientific and technological applications in the field of electromagnetism. However, the technical details of the two are quite different, so it is not easy to compare them. So I did a little research on the field of wireless power transmission during my master's degree, and answered the wireless power transmission technology in a brick-by-brick way, expecting someone to supplement the details of superconducting technology. Both the master's and doctor's directions are wireless energy transmission. Everyone agrees that superconductivity is higher than wireless energy transmission. Once the research breaks through, it is of epoch-making significance. At present, wireless energy transmission mainly solves the problem of safe and convenient power supply in some special occasions. The progress of superconductivity will directly lead to the progress of wireless energy transmission (the increase of efficiency and distance). The progress of wireless energy transmission has no contribution to the progress of superconductivity, which shows that superconductivity is a more basic and instructive subject, and the application of wireless energy transmission can solve the safety problems in many special occasions. For example: underground power supply, underwater power supply, electric toothbrush charging, large-angle rotating mechanism power supply, medical device charging in human body, etc. The same point is that it is inconvenient or even impossible to use contact power supply. The mainstream wireless energy transmission can be divided into near-field wireless energy transmission (electromagnetic induction type, magnetic coupling resonance type) and far-field wireless energy transmission (microwave, laser) according to the distance. The electromagnetic induction type has high efficiency, high power and the nearest distance (several centimeters to dozens of centimeters, the efficiency is over 90%, and the power can reach tens of kilowatts). The advantages of magnetic coupling resonance type are high efficiency, low power and long distance (several meters efficiency, 90% of one meter MIT, 40% of power, several hundred W). Far-field wireless energy transmission is inefficient and bulky, which is difficult to realize. From the perspective of engineering application, the popularization of superconductivity is still far away, and the popularization of wireless energy transmission is advancing rapidly.
