Intro:

Our ability to travel faster across the world has consistently been a catalyst for change.
This effect can be seen right back to the domestication of the horse.
It allows civilizations to expand and spread information and resources faster than ever.
So where is the next great innovation in commercial travel?
The fastest civilian vehicle - the Concorde had a top speed of Mach 2, but it needed to fly
at 18 000 meters. If it flew lower, the drag and heat generated from aerodynamic friction
would've limited its top speed.. Consider this: the outside temperature at this altitude is -57 degrees Celsius.
Yet the nose of the Concorde could reach 127 °C.. Naturally, if we want to move faster, closer to the Earth's surface, we need a way to
limit the friction our vehicles experience. This is exactly what the hyperloop aims to do.
So how does it work?. The pressure inside the Hyperloop tube would be lowered to a fraction of the normal atmospheric pressure.
This minimizes the friction the vehicle will experience due to air.
But even having a small amount of air in the tube can cause some serious issues.
Due to something known as the Kantrowitz Limit, at lower speeds, there is enough space
between the pod and the tube for air to get by.. But as the speed increases, this reaches a limit,. and the pod begins to push large volumes of air ahead of it.
This limits the speed immensely. We can fix this by installing a compressor fan
