Elon Musk's Hyperloop
Hyperloop holds the promise of transporting people and goods as fast as an airliner and more cheaply than a train.
By accelerating pods suspended in a near vacuum, the theory is that travel at up to 760mph would be possible. Although there are ambitions to have a working system by 2025, there are numerous technical hurdles to overcome before a working Hyperloop system can be built.
This gallery explores the various projects to develop Hyperloops that have sprung up around the world, since Tesla and SpaceX CEO Elon Musk popularised the concept in 2013, with a presentation that garnered attention worldwide.
During that presentation Musk presented this sketch, as part of his pitch for a Hyperloop transportation system capable of travelling between San Francisco and Los Angeles in just 35 minutes, which he said could be built for about $6bn.
