US Navy creates a superconductor that works at room temperaturelunes, 18 marzo 2019 A scientist working for the US Navy has applied for a patent for a superconductor at room temperature, a potential paradigm shift in power transmission and computer systems.A superconductor at room temperature is a material that is capable of exhibiting superconductivity – lossless energy transmission – at temperatures around 25 degrees Celsius. Current superconductors work when they cool near absolute zero, and the hottest superconductor, hydrogen sulfide, only works at -70 degrees Celsius.Salvatore Cezar Pais is registered as the inventor in the United States Navy patent application made public on Thursday by the US Patent and Trademark Office.The application states that a superconductor at room temperature can be constructed using a cable with an insulating core and an aluminum coating PZT (lead zirconate titanate) deposited by vacuum evaporation with a penetration depth thickness of London and polarized after the deposition.An electromagnetic coil is placed circumferentially around the coating so that when the coil is activated with a pulsed current, a non-linear vibration is induced, allowing superconductivity at room temperature.«This concept allows the transmission of electrical energy without losses and exhibits optimal thermal management (without heat dissipation),» according to the patent document, which leads to the design and development of new energy generation and collection devices with enormous benefits for the civilization.
