From Interesting Engineering via Hyperloop One
On paper, the Hyperloop is an engineering marvel that promises to set supersonic travel underground. The system is proposed to carry people around the world at speeds nearing, and eventually exceeding, the speed of sound. The idea is to carry people inside a vacuum tube at supersonic speeds. Although it looks great on paper, in the real world, a full-scale Hyperloop may not be realized for many more years to come.
Currently, there are many problems plaguing the Hyperloop – begging the question, is it practical?
Small scale preliminary experiments reveal the Hyperloop is entirely feasible and more so, it functions extraordinarily well. However, constructing a perfect tube hundreds of kilometers long capable of sustaining a near perfect vacuum will undoubtedly be one of the greatest engineering challenges in the 21st century.
