In 2013, Elon Musk first made his idea of the Hyperloop public.
The Hyperloop is similar to the small vacuum tubes that can be found at banks and retail stores that are often used to move money quickly in sealed containers.
Now the concept is to make the tubes and capsules much larger in order to carry passengers and maybe even other vehicles.
Instead of using just air pressure alone to move, the Hyperloop will have similar technology to bullet trains that use magnets to propel themselves forward. The tube that the Hyperloop will travel through will have some of the air pumped out of it. This will allow the capsule to travel through much more easily without having to deal with a significant amount of air pressure.
The air that is left over in the tube will be pushed downward to create a cushion of air underneath the capsule. It works like an air hockey puck to glide effortlessly. If we take a step back, this type of travel eliminates friction everywhere. There’s very little friction due to air in the tube, and there’s almost no friction along the bottom of the capsule.
Because the Hyperloop has an extreme lack of friction means that it can move extremely quickly, and be incredibly energy efficient.
You might be wondering how quickly it can move. Well, estimates put it at 760 miles per hour (1200km/hr). That’s insanely fast, we’re talking Los Angeles to San Francisco in just 35 minutes, (That's normally a 6 hour car drive, or 1 hour flight!).
