Transport needs to be decarbonized at every level if we are to meet climate goals. One of the most effective ways to reduce the emissions from midrange travel distances is via electric trains, but even the fastest locomotives are quite slow by plane standards. This is the problem the ultrafast Hyperloop was intended to fix, and recent developments could be bringing it closer to a reality again. One proponent of the idea, Hyperloop Transport Technologies (TT), has acquired the financial tools it needs to move to the next stage of development.
