Do you know:  Fifth Mode of Transport- Hyperloop

Hyperloop is considered to be the fifth mode of transport. Hyperloop is described as a sealed tube or system of tubes from which most of the air is removed so that the pod could travel substantially free of air resistance or friction. It is intended to convey people or objects at hypersonic speeds. If implemented, it could travel passengers at over 700 miles or more in an hour in a floating pod. Hyperloop is based on the vactrain concept which employs magnetically levitating trains in the form of capsules in the evacuated (airless) or partly evacuated tubes. About this Hyperloop concept, Elon Musk publicly mentioned it in 2012. His initial concept incorporated minimized-pressure tubes in which pressurized capsules ride on air bearings driven by linear induction motors and axial compressors. Then in August 2013, The Hyperloop Alpha concept was first published. In this, Musk set out a route running from Los Angeles and San Francisco.  He said that this could be safer, faster, more affordable, weather-proof, self-powering -- and less disruptive to people living along the route. Is Hyperloop like Linux? As we all know, Under its open-source licensing, Linux is freely available to anyone. Likewise, Musk threw the idea open to anyone who wanted to develop it and many companies are already on it. Among them are Virgin Hyperloop One, HTT, TransPod, Arrivo, and others. Each is developing a slightly different set of technologies, but the fundamental underlying idea remains the same.  About its working -

Hyperloop mainly consists of two parts - tubes consisting of tracks and capsules(pods) carrying passengers. Hyperloop encloses the capsules in a reduced-pressure tube, most of the air but not all is pumped out from the tubes to reduce the friction, effectively allowing the trains to travel at aeroplane speeds while still on the ground. Hyperloop capsules float above the tube's surface on a set of 28 air-bearing skis. The track generates the air cushion to keep the tube as simple and cheap as possible. Some versions of Hyperloop use magnetic levitation rather than air skis to keep the passenger pods above the tracks. Pod gets its initial velocity using an electric motor. The tube track is designed to be immunized against bad weather and natural disasters such as earthquakes. There is a capacity of about 28 passengers per capsule. Approximately capsules depart every 2 minutes, which is the average departure time of capsules. Some Key points and Drawbacks - The technology offers a very fast speed of transportation. On the other hand, the high speed of the capsule may cause dizziness to the passengers travelling due to vibration and jostling. It offers low power consumption and a low-cost transportation system in long run but the initial cost of investment is very high and risky to maintain. It is immune to bad weather conditions and is resistant to earthquakes.
