Hyperloop: Expectations vs. Reality
From the early ancient age to now the mode of transportation is continuously changing. We are continuously improving the speed of the transportations system as per our requirement. Today the fastest mode of transport we have are Bullet Trains and Aeroplanes. In bullet trains, the maximum possible speed which has been achieved is from 500 to 600 km/hr, in commercial flights we have the speed around 800 to 1000 km/hr. You can see the demand for speed is increasing and it is not convenient for many people to travel in the sky, so a new concept of Hyperloop has come out as a solution. It is similar to the train but not a train. This concept to the world first introduced by Elon Musk in 2012.
When Elon Musk first presented the concept of hyperloop to the world in 2012, after that many companies have started to work on it as it is made open source. The concept behind Hyperloop is:-
There is a big hollow tube connected through one City to another and is fixed on Pillars as shown in the figure. The Pods (in which passengers will seat) will move inside the tube at very high speed, just like a train, but it will not be similar to trains. Where many bogies are connected together. Hyperloop contains many small pods which will travel inside the tube.
It consists of a linear motor i.e, it has the electric motor but not a round one, which has the inner and outer shell. It is the linear distribution of the same thing. The two main parts of a motor rotor & stator, here in hyperloop the stators are fixed inside the tube linearly while the other part, the rotor will be mounted on pods. As soon as the power supply will be given the pods will start moving and keep on accelerating, depending on the power supply.
Hurdles in the making of hyperloop
Here in hyperloop, the target speed is 760 miles per second that is around 1200km/hr, but the air pressure inside the tube will be the main hurdle in achieving such speed. To cope up with that some pumps are fixed inside the tube which will continuously keep on extracting the air and try to create a vacuum inside the tube. But will not make a complete vacuum, air pressure will be very less same as in very high altitude.
Again as the pod will move inside the tube, it will face too much air friction at front face, which is again a speed barrier, therefore it will contain a compressor at its front to suck the air and pass it through the fringes, due to which air will pass by elevating the pod and providing the air lubrication as shown in fig.
In order to stop it or to apply brakes forces will be applied in the opposite direction by changing the polarity of the supply. Hyperloop will acquire very less space as it is fixed on Pillars and thereby tubes. At many places, its trial has already been started. In India also hyperloop will be launched from Mumbai to Pune and other routes too. One more major problem is what will be the effect on the persons sitting inside the pod, when the train will travel at such a high speed.
It is a brief explanation of Hyperloop, the future of transport, more details about the topic will be published soon. You can get the answers to the questions like.
which company is currently working on it? when it will start? what will be maximum possible speed? will it be launched in your city? what is hyperloop one? and many more…
