That sounds great, right?
Too bad he's not planning on building it:
During a Tesla earnings call Thursday, Musk said he would reveal plans for the Hyperloop on Monday. But he said he is too focused on other projects to consider actually building it.“I think I kind of shot myself by ever mentioning the Hyperloop,” he said. “I don’t have any plans to execute, because I must remain focused on SpaceX and Tesla.”
But just because Musk is too busy to cut through all the red tape required to make the Hyperloop a reality doesn't mean it will never happen. The plans he's unveiling Monday are open source, so anyone can use or modify them.
