This previous weekend, a milestone was reached with hyperloop development: the first passengers traveled down the vacuum tube, reaching a speed on 107 mph. I find hyperloop to be exciting in part because it was lifted straight out of science fiction. I’m particularly interested because travel times to the coasts will have a reduction of at least 50% if all it does is eliminate layovers at airports. It also substitutes electricity for jet fuel, which can be provided by renewable or renewable methane and doesn’t require complex synthesis and refining steps.
