DO YOU KNOW WHAT IS HYPERLOOP?


The Hyperloop is a proposed mode of passenger and freight transportation, first used to describe an open-source vactrain design released by a joint team from Tesla and SpaceX. A hyperloop is a sealed tube or system of Tunnels with low air pressure through which a pod may travel substantially free of air resistance or friction. The Hyperloop could convey people or objects at an airline or hypersonic speed while being very energy efficient. That would drastically reduce travel times versus trains as well as planes over distances of under approximately 1,500 kilometers (930 miles).


How does a Hyperloop tube work?



The basic idea of Hyperloop as envisioned by Musk is that the passenger pods or capsules travel through a tube, either above or below ground. To reduce friction, most but not all of the air is removed from the tubes by pumps.
Overcoming air resistance is one of the biggest uses of energy in high-speed travel. Airliners climb to high altitudes to travel through less dense air; in order to create a similar effect at ground level, Hyperloop encloses the capsules in a reduced-pressure tube, effectively allowing the trains to travel at airplane speeds while still on the ground.
In Musk's model, the pressure of the air inside the Hyperloop tube is about one-sixth the pressure of the atmosphere on Mars (a notable comparison as Mars is another of Musk's interests). This means an operating pressure of 100 pascals, which reduces the drag force of the air by 1,000 times relative to sea level conditions and would be equivalent to flying above 150,000 feet.


How do Hyperloop capsules work?



The Hyperloop capsules in Musk's model float above the tube's surface on a set of 28 air-bearing skis, similar to the way that the puck floats just above the table on an air hockey game. One major difference is that it is the pod, not the track, that generates the air cushion in order to keep the tube as simple and cheap as possible. Other versions of Hyperloop use magnetic levitation rather than air skis to keep the passenger pods above the tracks.

The pod would get its initial velocity from an external linear electric motor, which would accelerate it to 'high subsonic velocity and then give it a boost every 70 miles or so; in between, the pod would coast along in near-vacuum. Each capsule could carry 28 passengers (other versions aim to carry up to 40) plus some luggage; another version of the pods could carry cargo and vehicles. Pods would depart every two minutes (or every 30 seconds at peak usage).

How would Hyperloop be powered?


The pods will get their velocity from an external linear electric motor -- effectively a round induction motor (like the one in the Tesla Model S) rolled flat. Under Musk's model, the Hyperloop would be powered by solar panels placed on the top of the tube which would allow the system to generate more energy than it needs to run.
