Some people engage in "mere prattle without practice." Elon Musk is not one of those people. In a tweet he posted today, the Boring Company has 'verbal govt approval' to build an underground Hyperloop. The proposed route will take travelers (and possibly cargo) from New York to Washington DC, with stops in Philadelphia and Baltimore in a mere 29 minutes.
While 'verbal govt approval' can be interpreted in may ways, this is no doubt a win on many levels. Formal approvals can take some time but i'm optimistic that it will happen sooner rather than later.
Presumably, the Boring Company will dig the actual tunnels and ready the infrastructure but the verdict is still out on who would build the actual Hyperloop. Hyperloop Transportation Technologies and Hyperloop One are the two front runners in the race to build the world's first Hyperloop.
So what does this really mean? For starters, it would be a huge win for commuters. Imagine that you work in NYC. Your DC office wants to go over the blueprints for a new hotel with the developer before he leave on vacation. With this proposed Hyperloop route, you could get to DC from NYC in about 29 minutes!
The other huge win is that it opens the door to innovation. NYC to DC has been historically served by Amtrak trains, which are dreadfully slow. The Acela Expresses 'high speed train' has an average speed of 82 MPH (hardly high speed) and only attains 150 MPH on 28 miles of the route. Not to mention that the trip takes 2 hours and 45 minutes. That's not good enough. Amtrak and other potential competitors will need to innovate in order to compete.
The details are scant but I look forward to the day when I can look back at Elon's tweet, smile, and remember that the future of travel began on that day.
