21st century

ジェームズ・ポーウェルは1960年代に超伝導磁気浮上式鉄道を共同で発明した人物であり、2001年にはスペースローンチに磁気浮上式真空チューブ列車を使用するという構想の研究を率いた。(理論上は現在のロケットよりも2桁限界費用が低い)　James R. Powell, co-inventor of superconducting maglev in the 1960s, has since 2001 led investigation of a concept for using a maglev vactrain for space launch (theoretically two orders of magnitude less marginal cost than present rockets), where the StarTram proposal would have vehicles reach up to 14,300 - 31,500 km/h (8,900 - 19,600 mph) within an acceleration tunnel (lengthy to limit g-forces), considering boring through the ice sheet in Antarctica for lower anticipated expense than in rock.

ET3 claim to have achieved some work that resulted in a patent on "evacuated tube transport technology" which was granted in 2009. They presented their idea 2013 on public stage.

In August 2013 Elon Musk, CEO of Tesla and SpaceX, published the Hyperloop Alpha paper, proposing and examining a route running from the Los Angeles region to the San Francisco Bay Area, roughly following the Interstate 5 corridor. The Hyperloop concept has been explicitly "open-sourced" by Musk and SpaceX, and others have been encouraged to take the ideas and further develop them.

To that end, a few companies have been formed, and several interdisciplinary student-led teams are working to advance the technology. SpaceX built an approximately 1-マイル-long (1.6 km) subscale track for its pod design competition at its headquarters in Hawthorne, California.
