Dutch #hyperloop company #Hardt ('fast' in Dutch) has been declared bankrupt. (But Delft University of Technology students continue working on design and development.)
Very futuristic and kickstarted by someone we (now) know to be fascist, but I'd find it cool if these efforts get to fruition. Between airplanes on green energy (be it sustainable bio-fuel or electricity) and a magnetic train in a vacuum tube, I bet on the latter.
