China breaks speed record. https://cdn.steemitimages.com/DQmX4w4qNgFJfKVDghYC2imDdiyarLEaPJrgPZ51sc4KKYE/image.png Image source: The result, a visual blur and an acceleration that rivals that of a military fighter. Researchers from China's National University of Defense Technology accelerated a one-ton vehicle from 0 to 700 km/h in less than 2 seconds using the superconducting magnetic room, all on a test track of just 400 m and then a complete stop. It's not a test for passengers, of course, the force exceeds 10G in acceleration, enough to make even experienced pilots faint, but that was never the goal. The system uses high-temperature superconducting magnets cooled with liquid nitrogen to about -196º, still extremely cold, but much more viable than traditional superconductors that require liquid helium. https://www.youtube.com/watch?v=UCPIDHg5sp8 Today there is only one high-speed Maglev train in commercial operation in the world and it is in China. This creates intense magnetic fiel
