H is for Hyperloop

Saudi Arabia plans to build a Hyperloop that would shrink commutes from hours to minutes. The royal family has created a new plan called "Vision 2030," which provides a blueprint for modernizing cities across the kingdom. As part of this plan, the country says it hopes to build a Hyperloop, a massive, high-speed pneumatic transit system that would travel between several cities in Saudi Arabia and the UAE.
