Another world changing idea by one of the living legends, Elon Musk, after the reusable rockets in the field of space travel.








What is a hyperloop?

Hyperloop is essentially a train system that Musk calls "a cross between a Concorde, a railgun, and an air hockey table". It's based on the very high-speed transit (VHST) system proposed in 1972, which combines a magnetic levitation train and a low pressure transit tube. It evolves some of the original ideas of VHST, but it still uses tunnels and pods or capsules to move from place to place.

Hyperloop is being proposed as an alternative to short distance air travel, where the system will be much faster than existing rail networks and much cleaner than flight. But there are practical implications that have to be considered on a short stop-start journey, such as the acceleration and deceleration sensation that passengers would go through.

Musk's Hyperloop will take this to the next level by traveling through low pressure tubes.

Hyperloop will be built in tunnels that have had some of the air sucked out to lower the pressure. So, like high-altitude flying, there's less resistance against the pod moving through the tunnel, meaning it can be much more energy efficient, which is desirable in any transport system.

The original VHST proposed using a vacuum, but there's an inherent difficulty in creating and maintaining a vacuum in a tunnel that will have things like stations, and any break in the vacuum could potentially render the entire system useless. For Hyperloop, the idea is to lower the air pressure, a job that could be done by regularly placed air pumps.

Low pressure, however, means you still have some air in the tunnels.

The air bearing and passive maglev ideas are designed not only to levitate the pod, but also see the pod moving through the air, rather than pushing the air in front of it and dragging it along behind. The air cushion will see the air pumped from the front of the pod to the rear via these suspension cushions. The tunnels envisioned are metal tubes, elevated as an over ground system.

Musk has suggested that solar panels running on the top of the tunnels could generate enough electricity to power the system. It could run as an underground system, too.

When it is coming?

Hyperloop Transportation Technologies (HTT), will begin building a track in Abu Dhabi with the aim of having it up and running by 2020.It will be a 10 kilometer track developed close to the site of Expo 2020 and Al Maktoum International Airport, on the border of the Abu Dhabi and Dubai emirates. HTT signed an agreement with Aldar Properties PJSC, the developer behind Yas Island's Formula 1 racing circuit.
