Superconductor technology for smaller, sooner nuclear fusion

Good news! Could this approach finally succeed to demonstrate net energy generation through nuclear fusion for the first time?

Global Warming/Climate Change is a hoax!

"... Within the past few years, groundbreaking high-temperature superconductor technology (HTS) sparked a new vision for achieving practical fusion energy. This approach, known as the high-field pathway to fusion, aims to generate fusion in compact devices on a shorter timescale and lower cost than alternative approaches. ... Now a team ... has developed and extensively tested an HTS cable technology that can be scaled and engineered into the high-performance magnets. ... The innovative technology described in the paper is a superconducting cable that conducts electricity with no resistance or heat generation and that will not degrade under extreme mechanical, electrical, and thermal conditions. Branded VIPER (an acronymic feat that stands for Vacuum Pressure Impregnated, Insulated, Partially transposed, Extruded, and Roll-formed), it consists of commercially produced thin steel tapes coated with HTS compound — yttrium-barium-copper-oxide — that are packaged into an assembly of copper and steel components to form the cable. ...VIPER technology also presents a powerful approach to a particular problem in the superconducting magnet field, called a quench, “that has terrified engineers since they started building superconducting magnets,” says Hartwig. A quench is a drastic temperature increase that occurs when the cold cables can no longer conduct electrical current without any resistance. "
