The Hyperloop transportation proposal designed by Elon Musk plans to break ground in 2016 on a 5-mile track that will serve Quay Valley in California. The test track will be used to design and test pods that could transport people up to 760 miles per hour. It will start carrying passengers as soon as 2018. Space X is also holding a pod competition for university students and independent engineering groups.
