The Hyperloop is a proposed mode of passenger and frieght transportation , the term was invented to describe the modern open-source project. Hyperloop is described as 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 Hyperloop could potentially convey people or objects at airline or hypersonic speed while being energy efficient compared with existing high-speed rail systems. This, if implemented, may reduce travel times compared to train and airplane travel over distances of under approximately 1,500 kilometres (930 miles). The Hyperloop concept has its roots in a concept invented by George Medhurst in 1799 and subsequently developed under the names pneumatic railway, atmospheric railway or Vactrain . Elon musk mentioned the Hyperloop in 2012, bringing it back to...
