A company called ET3 has plans in the works for the Evacuated Tube Transport, a high-speed transportation tube that uses magnetic levitation. The ETT can travel at speeds of up to 4,000 miles per hour, and each tube seats a maximum of six people and comes with a baggage compartment. How does it go so fast? It’s airless and frictionless and could have you from New York to Los Angeles in 45 minutes, as opposed to the nearly five hours a direct flight would take. It could even have you depart from New York and be in Beijing in two hours.
The tubes would be set up like freeways to prevent crowding and traffic congestion problems. Plus, ET3 claims that passengers need not worry about feeling discomfort while traveling at such high speeds. The high velocity at which the tubes move is equal to 1G of force at top speed, which is similar to the force felt by someone traveling in a car on the freeway.
