Hyperloop technology:  It is aimed to travel at a top speed of 1100 km per hour. In order to understand the working of Hyperloop,it is important to realize that Hyperloop is more an engineering innovation than a new physics phenomenon .That said,its a technological marvel only a mind like Elon Musk could come up with. First how would you achieve supersonic speed? 1 ..One way would be to first decrease the density  as drag depends propotionally on density of air sorrounding it.The heavier the air,the more work you have to do to move against it. 2 Another way to achieve this is to prevent "divergence drag."Before you worry that I have transcended into rocket science realm,note that there is something known as breaking the sound barrier. After a particular speed,the hyperloop capsule cannot simply pass through air. It is moving so fast that it must push air along with it. To understand this imagine a circular  (Loop) tube filled with water with a piece of solid cork(cap
