Startup aims to transform the power grid with superconducting transmission lines
- JumpCrisscross 2y agoThe cables “make use of superconducting cables and a proprietary cooling system.” This story is a nothingburger without more detail on this system.
- gus_massa 2y ago> Today VEIR’s system is passively cooled with nitrogen, which runs through a vacuum-insulated pipe that surrounds a superconducting cable. That makes sense from the theoretical point of view, but runing a vaccum tube for kilometers with liquid nitrogen inside with some superconductor inside looks very difficult. > Last year in Woburn, Massachusetts, a power line was deployed across a 100-foot stretch of land. It's a good start, but very short in comparison to power lines. Did they deploy the line on the floor or hanging in the air where wind and birds can deform it? > VEIR’s first alternating current (AC) overhead product line is capable of transmission capacities up to 400 megawatts and voltages of up to 69 kilovolts, That's almost 6000 Amps. I'm not very updated with modern high temperature superconductors, but they use to not like very high currents.
