What Is Elon Musk’s Hyperloop tunnel is a high-speed transportation concept designed to revolutionize travel by using low-pressure tubes to move passenger pods at extremely high speeds with minimal resistance. Originally proposed by Musk in 2013, the Hyperloop system aims to transport passengers and cargo at speeds exceeding 700 mph (1,127 km/h), potentially cutting travel time between major cities to a fraction of what it takes today.
