The hot topic recently is room-temperature superconductivity. So what exactly is superconductivity? Will it really be as people imagine? If room-temperature superconductivity is achieved, will the world be reshuffled? Will the island suspended in the air in Avatar be imprinted in reality? Will people live in the "Cloud Top Palace" in a few decades?
Superconductivity refers to the phenomenon that the resistance of certain materials suddenly drops to zero when the temperature is below a critical temperature, resulting in the phenomenon of conducting electricity without resistance. It has the following main characteristics:
Zero resistance - Electric current can flow without loss in a superconductor. In simple terms, all electrical items we use will no longer generate heat, electricity will be incredibly cheap, and chip performance will be greatly improved.
Meissner effect - superconductors can completely repel external magnetic fields. This makes magnetic levitation more popular, which is why some people boldly imagine that the island of Avatar floating in the air will be printed into reality.
Josephson effect - Superconductors can carry very high currents without loss. You will no longer see bulky devices such as transformers.
The critical temperature of currently known superconductor materials is relatively low, requiring low temperature conditions such as liquid helium to achieve a superconducting state, which limits their application. If room temperature superconductivity is achieved, it will be a major scientific breakthrough.
For the cryptocurrency industry, if room temperature superconducting technology is put into practical use, it can improve the computing speed and power efficiency of mining chips, greatly improving the performance of mining machines. It can also reduce the operating costs of supercomputers and may promote the development of some blockchain technologies that require high computing power. However, its impact depends on the actual situation, and the specific effect remains to be seen. In general, the progress of superconducting technology has a positive driving effect on the development of science and technology.
