2. Ultra-High-Speed Rail


Chinese researchers have developed a supersonic train that redefines the term “high-speed rail.” It’s not using rails at all, but magnetic levitation — maglev — with a theoretical top speed of 1,800 MPH. That’s three times the speed of an airliner, and could get you from New York to L.A. in less than 90 minutes. The train travels inside a vacuum tube, and so far is in the early stages of testing.
