Have you ever thought about going from Dhaka to Chittagong within 30 minutes without facing any difficulty? It seems nearly impossibleBut Hyperloop is here to give you that thought in your mind and taking the future into reality. The future of transportation ‘Hyperloop’ is becoming real.

Hyperloop is a super speed ground-level transportation system in which people could travel in a hovering pod inside a vacuum tube at speeds as high as 760 mph (1220 km/h), just shy of the speed of sound.

The Hyperloop concept has its roots in a concept invented by George Medhurst in 1799 and subsequently developed under the names pneumatic railway, atmospheric railway or vactrain. Elon Musk mentioned the Hyperloop in 2012, bringing it back to public attention.

It has three major components:

1) A tube 2) Pod 3)Terminal. The tube is a large sealed, low-pressure system that can be constructed above or below ground. A coach runs inside this controlled environment and is often referred to as a pod. The pod employs magnetic or aerodynamic levitation (using air-bearing skis)along with electromagnetic or aerodynamic propulsion to glide along a fixed guideway.

Motor: A modular array of 4 propulsion engines flank each side of vehicle and support cruise velocities near 1,000 km/h in under 5 minutes. The motor has a 50% better power factor, and 50% more compact. It can reach speeds 2-3 times faster than competing system.

Vacuum: In the pod, the air pressure is reduced to the equivalent of 200,000 ft. above the sea level. The bear vacuum lowers aerodynamic drag significantly, allowing for higher speeds to be achieved while using minimal energy.

Magnetic Levitation: It levitates from the top using an attractive electromagnetic force, powered by onboard batteries. This levitation system is over 8 times more efficient compared to the world’s fastest maglev train in operation today and enables high speed switching with no moving track

Guidance: Magnets on the vehicle lift the vehicle to the passive track, while guidance engines provide active guidance forces.

Let’s have a look at route estimator how much time will need to travel from Dhaka to Chittagong with ‘Hyperloop’ –

Many companies are working on Hyperloop Project but among them Richard Branson's Virgin Group is taking the lead of this part. ‘Virgin Hyperloop’ has made some significant progress to this project including first passenger travel test.

World’s first Hyperloop Passenger Test:

The first passenger test on Hyperloop was conducted safely on November 8, 2020 making a history in the field of future transportation

What makes Hyperloop different?

There are two big differences between Hyperloop and traditional rail. Firstly, the pods carrying passengers travel through tubes or tunnels from which most of the air has been removed to reduce friction. This should allow the pods to travel at up to 750 miles per hour.

Secondly, rather than using wheels like a train or car, the pods are designed to float on air skis, using the same basic idea as an air hockey table, or use magnetic levitation to reduce friction.

What will it feel like to travel in a Hyperloop?

Critics of Hyperloop have warned that travelling in the tube might be an uncomfortable experience, due to nausea-inducing acceleration, plus lateral G-force on bends in the route. However, Virgin Hyperloop One says that a journey via Hyperloop will feel about the same as riding in an elevator or a passenger plane.

Though it is exciting for us to have such a fast transportation system in future, but the cost is also a thing that we need to look atDubai, Abu Dhabi, India, Mexico City are interested to make an implementation of Hyperloop Technology. The project has heavy cost and in order to make this project real, a good amount of lands, securities and other factors are need to look at. But, we can say that, this will surely change the field of transportation in future that no one ever thought.
