High temperature superconductors.
Approx. 100 years ago, the physicist H.K. Onnes discovered that mercury suddenly loses its electrical resistance below a temperature of 4.2 Kelvin. Subsequently, superconducting metal alloys with transition temperatures of up to 23 K were developed. In the last 30 years, this facilitated pioneering developments, primarily in medical technology, but also in the physical research. However, considering its versatility, superconductivity long remained a niche technology. The main reason is the difficulty of maintaining such low temperatures. As only helium is liquid below 23 K, it is the only possible coolant. However, it is expensive and difficult to handle. Also, a significant amount of energy is required to liquefy it.
