Elon Musk revealed plans for his radical new form of transportation called the Hyperloop today. Musk described the capsule as being aluminum that could carry both humans and car-sized vehicles. The tubes would form a loop shape, the long-lengths of which would travel parallel to one another. They would be made of steel, welded together, and will sit only about 100 feet apart held up by pylons. Those inside the tube could travel up to 800 miles per hour and, if traveling in a car-capsule, could simply drive out of the tube once the destination has been reached.
