It’s one of the most important breakthroughs in experimental physics, and is electrical resistance in mercury vanishes when it is cooled to temperatures close to absolute zero, which is 0 K (-273.15°C or -459.7°F). This phenomenon is known as superconductivity. Soon it was found that other metals and alloys also become superconducting at very low temperatures. For example, if one cools a ring of lead below 7.22 K (-265.93°C or -446.67°F) and induces a current in it, this current will keep flowing indefinitely.
The temperature at which a metal becomes superconducting is called the critical temperature. The higher the critical temperature of a metal or alloy, the easier the material is to use in technical applications. Superconductors have only found a marginal application in technology

bubu Vo Hoang: If you want to know more information, you can have a research at Time medical at www.Time-medical.com . They are using this system also
The most important application of superconducting wires and coils will be in the transformation and storage of energy. Magnets made with superconducting coils produce much stronger magnetic fields than those currently used in motors and generators; they are used in a number of large particle accelerators. Superconducting coils are used in prototype motors and transformers, allowing their size to be reduced considerably. Because a current in a superconducting closed loop flows indefinitely, such a loop can be used for energy storage. The stored energy can be used when required by breaking the closed circuit. Plans exist for building huge superconducting coils mounted underground to store thousands of megawatts of energy. Actually, Time Medical is using this system effectively.
Though it is called "high temperature", that is a relative term. I believe that early tests required cooling environments of near absolute zero. The "high temperature" environments are still cooled by liquid nitrogen but are cooled to something closer to 0 degrees Fahrenheit.
This wire is 100 times more efficient than typical copper wire. The benefit in big cities where space in underground conduits is already tight is that three 3" copper cables can be replaced by a wire the width of a pencil. Additionally, the wire has can carry data and has special surge protection capabilities. When the towers went down on 9/11, much of Manhattan lost power. This can be much more limited with Amperium.
I worked on this In industry, HTSLM can be used in producing transportation lines, as well as some mechanical devices move horizontally or vertically, such as the transports system for the semiconductor production line, the wireless linear elevator.
The performance of a 12-mm high-temperature superconducting (HTS) surface coil for in vivo microimaging of mice in a standard 1.5T clinical whole-body scanner was investigated. Systematic evaluation of MR image quality was conducted on saline phantoms with various conductivities to derive the sensitivity improvement brought by the HTS coil compared with a similar room-temperature copper coil.
