Vacuum tube trains could be in the future of America. This is an old concept, with new technology; A near vacuum tube with magnetic levitation tracks.
Several organizations are trying to build prototypes that will show that it can be done. But the autocracy will try to stop it. They have so much to loose by people not using gasoline cars.
The mega corporations are the only ones with enough money to build these multi-trillion dollar fantasy transportation systems. They sound like another futuristic promise to keep the worker drones pacified. So forget them and start building something for local transportation, ie: motorized cargo cycle trucks, or even a sexy electric micro car with pedals. Traveling to a distant cities will be a thing of the past soon, unless your rich.
