One of the two competing Hyperloop companies has made a major announcement concerning how it's going to make high speed transport a reality. Hyperloop Transportation Technologies has signed a deal with the Lawrence Livermore National Laboratory to harness Inductrack, a form of passive repulsion technology. Traditional MagLev systems require a constant supply of power, adding cost and complexity to most bullet train systems. By comparison, passive repulsion operates with a single series of magnets that can be mounted on each capsule. That's going to make Hyperloop a lot cheaper and easier to maintain, which should hopefully encourage more cities to consider buying one.
