Science Daily  May 24, 2022 Previous work showed that the body of superconducting cables could be cooled with helium gas, but the cable ends needed another medium for cooling, such as liquid nitrogen. To improve efficiency and practicality a team of researchers in the US (University of Colorado, Florida State University, industry) overcame that obstacle and were able to cool an entire cable system with helium gas. Removing the need for liquid nitrogen allowed them to make a highly compact superconducting power cable that can be operated in a continuous mode. The system is small and lightweight, and it allows […]
