"A hyperloop system involves passengers or freight transported by pods elevated by magnets, which travel within raised pipes. The pods can be propelled at 620mph (1,000kph), says Jay Walder, boss of Virgin Hyperloop One, one of the firms pushing the idea. At that pace 'you could move between Columbus and Chicago in 40 minutes', he says, so covering the 460 miles many hours quicker than by driving and at a cost (and overall carbon impact) that he says would be lower than flying." If the economics work, for both people and goods, and if the environmental externalities are lower than cars/trucks/trains/planes, then it would be great to have regional networks of hyperloops in the US. I say, bring it on!
