The high-speed transportation system called Hyperloop is getting attention all over the world. Last week, groups from the United States presented proposals for Hyperloop projects at a meeting in Washington D.C. Hyperloop is the name for a transportation system that uses strong magnets to move containers inside tubes. The containers could move both people and goods. The system is the idea of businessman Elon Musk, who created and owns the company SpaceX and the electric car maker Tesla. He wrote a study in 2013 explaining why businesses should consider investing in the project. He said that Hyperloop could move people and goods faster than high-speed trains.
