“It’s similar to what the Concorde did for air transport … This will revolutionize how we transport people from city to city.”Oh, lordy. Here's what the Concorde did for air transport. It created a very small, niche industry which offered a somewhat faster product than what existed. This product was available only at a huge markup to the main market. It had severely constricted capacity. Development cost 12 times (*) initial estimates (so much so that it is an above-the-fold example in the "cost overrun" Wikipedia article). It received massive government subsidies. And after 30 years of serving a very small market, it was retired from service.
Let me repeat that: the Concorde is no longer in service. It didn't revolutionize how we transport people by air. It first flew in 1976, and last flew in 2003. The 747 first flew in 1969, and continues to transport people by air today. If the Concorde had revolutionized how we transport people from city to city, we'd probably still be using it today. We're not. The jet? It revolutionized travel—before that most everyone crossed long distances of water by boat, and on land by train. The Concorde? We're still flying conventional jets.
And they're crowdsourcing this? Let me just take a flyer here. Elon Musk scribbled some ideas on a napkin (and the Tesla is doing great, at least when it's not catching fire) and now a couple people are crowdsourcing the project, and comparing it to something that, while a technological marvel, was for all intents and purposes, a financial disappointment.
However, unlike the Concorde, I doubt the Hyperloop will ever get off the ground.
(* Note that with the same level of overrun, the Hyperloop would cost $72 billion to construct, which is as much as the High Speed Rail proposal. Except the High Speed Rail system can carry 10 times the passenger load (or more). Remember, the Concorde only had 100 seats. Most everyone else flew—and still flies—on conventional jets.)
