When Richard Branson invested in futuristic transportation start-up Hyperloop One this week, he jumped into yet another market that's of deep personal interest to fellow billionaire entrepreneur Elon Musk.

Musk is credited with creating the idea of the hyperloop, a super speedy method of passenger travel that involves pressurized capsules. He also founded The Boring Company, which is setting out to build hyperloop tunnels.
