Elon Musk’s hyperloop idea would involve engineering a two-and-a-half ton pod that would be able run through a massive steel tube which would cover long distances. Once inside the tube‚ the pod would be able to reach incredible speeds of up to 760 mph. At these speeds‚ the hyperloop would be capable of traveling from Los Angeles to San Francisco in a little less than a half hour. The people and economies of those places where a Hyperloop would be built and/or run through would be drastically impacted
