Everything about Hyperloop that you want to know

The Hyperloop is a conceptual high-speed transportation system. It used part-vacuum tubes wherein pressurized capsules ride on air cushion. The tube are driven by linear induction motors and air compressors.

Idea

123-min

Entrepreneur billionaire Elon Musk first mentioned this concept for a “” in July 2012 naming it “Hyperloop.”

It would have no rails, be immune to whether, never experience crashes, be twice as fast as a typical jet, require low power, and be able to store energy for 24-hour operations.

Vactrain Concept

The High-speed rail encounters problems with friction and air resistance when vehicles approach excessive speeds.

The vactrain concept theoretically eliminates these problems by magnetically levitating trains in airless (or partly airless) tubes and tunnels.

Supersonic speed is possible, but the high cost and difficulty of maintaining a vacuum over long distances has prevented this system from being built.

The Hyperloop is similar to a vactrain system but operates at approximately one millibar (100 pa) of pressure.

Design

hyperloop-tech-1

The Hyperloop will use passenger/ cargo “capsules” or “pods” that run through a continuous steel tube maintained in a partial vacuum.

Passenger-only pods are to be 2.23 metres in diameter and are projected to reach a top speed of 760 mph (1,220 km/h).

Each capsule floats on a .5 to 1.3-millimetre layer of air provided under pressure to air-bearing “skis.”

The design proposes that passengers experience a maximum inertial acceleration of .5 g, or two or three times that of a Jet airliner on takeoff and landing.

Operation

Linear induction motors located along the tube would accelerate and decelerate the capsule to the right speed for each section of the cube route.

With rolling resistance eliminated and air resistance reduced, the capsules are theorized to glide for the bulk of the journey.

An inlet fan and air compressor would be placed at the nose of the capsule to transfer high pressure air from the front to the back of the vessel.

There will be no sonic boom even at <Mach 1 speed since there is warm, low-pressure air inside the tubes.

Suggested Route

The preliminary design document made public in August 2013 suggested a route running from the Los Angeles region to the San Francisco Bay Area.

the 354-Miles (570 km) route would run parallel to interstate 5 for most of its length.

At an average speed of 598 mph (962 km/h) and a top speed of 760 mph (1,220 km/h) the route could be traver in 35 minutes.

The Los Angeles to San Francisco trip currently takes more than 5 hours by car and 1 hour 15 minutes by plane.

Cost Estimates

1462954571-1886-hyperloop-1

Estimate have been pegged at $6 billion for a passenger-only version, and $7.5 billion for a passenger and vehicle/cargo version.

Transportation engineers in 2013 found the cost estimate unrealistically low given the scale of construction and reliance on unproven technology.

Experts predicted that actual costs would amount to around $100 billion.
