At a time when there are renewed debates in the United States about the future of the country's infrastructure, Godzilla vs. Kong's light flirtation with the idea of high-speed trains capable . This is precisely one (Remember that Area 51 is part of the test trucks, etc. A break at a station for a meal would mean a stop of you and your aero-car. They will never get the construction costs back: twin 50m bore tunnels over 1000's of kilometres? According to
And it turns out we've got the technology to do that today mag-lev rail lines remove all rolling friction from the energy equation for a train, and accelerating them through a vacuum tunnel can eliminate wind resistance to the point where it's theoretically possible to reach blistering speeds over 4,000 mph (6,437 km/h) using a fraction of the energy an airliner uses and recapturing a lot of that energy upon deceleration. developments expected into a

A superconducting maglev train in Yamanshi, Japan (source: Saruno Hirobano) The Gen 1 Startram launch system (while purely hypothetical at this point) would use an underground vacuum tube with a maglev rail inside - commonly referred to as a hyperloop - that is ~130km long and 2m in diameter. route. various other covert goings-on. And once you reach your top speed, you simply stop accelerating, apply no further energy, and coast. States. melted rock both as a lining for the hole and as a dispersal in LIFE
