Do you remember the massive hype around hyperloops when Elon Musk first mentioned the possibility of them? Years and coronavirus might have washed away the sensation but hyperloops are still existing ideas. They are more than ideas, to be fair, they are under construction!
A Hyperloop is a proposed mode of passenger and freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX. A Hyperloop is a sealed tube or system of tubes with low air pressure through which a pod may travel substantially free of air resistance or friction. The system could convey people or objects at airline or hypersonic speeds while being very energy efficient. This would drastically reduce travel times versus trains as well as planes over distances of under approximately 1,500 kilometres (930 miles).
Elon Musk first publicly mentioned the Hyperloop in 2012. His initial concept incorporated reduced-pressure tubes in which pressurized capsules ride on air bearings driven by linear induction motors and axial compressors.
