High-speed trains in low-pressure tubes have been around since 1799 when English inventor George Medhurst patented his wind pumps. Elon Musk released his Hyperloop Alpha white paper in 2013 in which he envisioned a new form of high-speed magnetic levitation (maglev) rail system in near-vacuum tubes that could travel at speeds of over 700 mph. VHO has testing facilities in the US, UAE and India and is looking to be ready for human passengers by 2022.”]
