In 2013 Elon Musk of Space X flaunted the idea of traveling through tubes in pod. Similar to when you send your check to the teller and a drive up bank. The air is sucked out of the tube creating a vacuum for the pod to travel with minimal resistance. This is some serious Jetson’s style traveling.
Hyperloop One is the company that is making the tube units. They have developed some working models already. Elon Musk of Space X and Hyperloop One have a contest in place for teams to build prototype pods and compete on who’s pod does the best. This event is open to High school and College students. You can take a look at the most recent competition on Engadget’s website.
In the original plan it is believed to be achievable to travel from Los Angeles to San Francisco, a 900 mile distance, in 30 minutes. You can stay abreast to the progress by checking HyperLoop Ones website.
