Hello friends, i am Sushil and am here to introduce a quite innovative and also revolutionary topic in front of you.

It’s the hyperloop one. I am guessing that may be many of you might have a slight idea of what it is and what’s so innovative about it . I will give a brief introduction about it.

Hyperloop is a trade name and a registered trademark of the Space Exploration Technologies Corporation (SpaceX) for the high speed transportation of passengers and goods in partially evacuated tubes.

Recently there has been a resurgence in interest in pneumatic tube transportation systems since being reintroduced, using updated technologies, by Elon Musk after 2012, incorporating reduced-pressure tubes in which pressurized capsules ride on an air cushion driven by linear induction motors and air compressors.

 Preliminary analysis indicated that such a route might obtain an expected journey time of 35 minutes, meaning that passengers would traverse the 350-mile (560 km) route at an average speed of around 600 mph (970 km/h), with a top speed of 760 mph (1,200 km/h). Preliminary cost estimates for the LA–SF suggested route were included in the white paper—US$6 billion for a passenger-only version, and US$7.5 billion for a somewhat larger-diameter version transporting passengers and vehicles —although transportation analysts doubted that the system could be constructed on that budget.

Developments in high-speed rail have historically been impeded by the difficulties in managing friction and air resistance, both of which become substantial when vehicles approach high speeds. The vactrain concept theoretically eliminates these obstacles by employing magnetically levitating trains in evacuated (airless) or partly evacuated tubes, allowing for speeds of thousands of miles per hour. However, the high cost of maglev and the difficulty of maintaining a vacuum over large distances has prevented this type of system from ever being built. The Hyperloop resembles a vactrain system but operates at approximately one millibar (100 Pa) of pressure.

Initial design concept

The Hyperloop concept operates by sending specially designed “capsules” or “pods” through a continuous steel tube maintained at a partial vacuum. Each capsule floats on a 0.5-to-1.3-millimetre (0.02 to 0.05 in) layer of air provided under pressure to air-caster “skis”, similar to how pucks are suspended in an air hockey table, thus avoiding the use of maglev while still allowing for speeds that wheels cannot sustain. Linear induction motors located along the tube would accelerate and decelerate the capsule to the appropriate speed for each section of the tube route. With rolling resistance eliminated and air resistance greatly reduced, the capsules can glide for the bulk of the journey. In the Hyperloop concept, an electrically driven inlet fan and air compressor would be placed at the nose of the capsule to “actively transfer high pressure air from the front to the rear of the vessel,” resolving the problem of air pressure building in front of the vehicle, slowing it down. A fraction of the air is shunted to the skis for additional pressure, augmenting that gain passively from lift due to their shape.

In the alpha-level concept, passenger-only pods are to be 2.23 metres (7 ft 4 in) in diameter and projected to reach a top speed of 760 mph (1,220 km/h) to maintain aerodynamic efficiency;the design proposes passengers experience a maximum inertial acceleration of 0.5 g, about 2 or 3 times that of a commercial airliner on takeoff and landing. At those speeds there would not be a sonic boom.

They use a custom electric motor to accelerate and decelerate a levitated pod through a low-pressure tube. The vehicle will glide silently for miles with no turbulance.

It’s happening faster than we are thinking. they have tested their motor back in May, 2016, and will test the full system in early 2017. They are  developing routes in five countries. Their goal is to be moving cargo by 2020 and passengers by 2021.

This is it and i will again be talking with the exact working and the way they are progressing towards their aim and how soon can they achieve it.

I will brief you about the exact working principle and their tests performed till now . 

Thanks and do share the blog if you like it and let me know your views about this concept.
