Superconductor Basics

When we push electrons through most conductors, there is resistance from other electrical fields that slows down the transmission of the electrical current and creates heat. In some materials, the electrons clump together in pairs (Cooper pairs) and move with reduced resistance. These materials are called superconductors and they are most effective at low temperatures […]

Startram MagLev Tube Space Launch System

Magnetic levitation is used to both lift railway trains off their guiding rail and to propel them forward along the rail. This reduces friction with the rail, leaving air resistance as the primary obstacle to forward speed. By operating a maglev transport inside a tube with evacuated atmosphere, the drag from air can also be […]
