Today's conventional modes of transportation of
people consists of four unique types: rail, road,
water, and air. These modes of transport tend to be
either relatively slow (e.g., road and water),
expensive (e.g., air), or a combination of relatively
slow and expensive (i.e., rail).
INTRODUCTION
 Hyperloop is a proposed new mode of transport
that seeks to change this pattern by being both
fast and inexpensive for people and goods.

 Hyperloop is a proposed mode of passenger and freight
transportation that would propel a pod-like vehicle through a near-
vacuum tube at more than airline speed.
 The pods would accelerate to cruising speed gradually using a
linear electric motor and glide above their track using
passive magnetic levitation or air bearings.
 The average speed 350-mile (560 km) ,with a top speed of
760 mph (1,200 km/h

The concept was introduced by Elon Musk of Tesla
motor , 2013
Each capsule floats on a 0.02–0.05 in (0.5–1.3 mm) layer of
air provided under pressure to air-caster "skis“ or by
magnetic levitation.
Linear induction motors located along the tube would
accelerate and decelerate the capsule.

Components of Hyperloop Transportation
System

 Sealed capsules carrying passengers that travel along
the interior of the tube.
 For travel at high speeds, the greatest power
requirement is normally to overcome air resistance.
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
CAPSULE

TUBE
 The tube is made of steel. Two tubes will be welded
together in a side by side configuration to allow the
capsules to travel both directions.
 Pylons are placed every
100 ft (30 m) to support
the tube.
 Solar arrays will cover
the top of the tubes in
order to provide power
to the system.

Low Pressure Tube
 The pressure inside the tube will be maintained around
100pa (less than atm. pressure).
 This low pressure minimizes the drag force on the
capsule while maintaining the relative ease of pumping
out the air from the tube.

 Linear accelerators are constructed along the length
of the tube at various locations to accelerate the
capsules.
 Stators are located on the capsules to transfer
momentum to the capsules via the linear
accelerators.
PROPULSION

 Space X has built a 1 mile long test track to conduct public
trials of its technology.
 Hyperloop One on November 8, 2016 announced a new
feasibility study with Dubai's Roads and Transport
Authority for passenger and freight routes connecting
Dubai with the greater United Arab Emirates

 Hyperloop one has met govt. official of NITI AYOG &
Govt. autority took part in a programme which discussed
vision for India organized by company.
 Hyperloop is potentially looking Indian sectors where
the system can be built:
 Chennai-Bangalore – 334 km in 20 minutes
 Mumbai-Chennai via bengaluru – 1102 km in 50 minutes
 Mumbai- kolkata via chennai – 220 min

 The Hyperloop as a whole is projected to consume an average of
21 MW.
Can it really be Self-powering?
 A solar array covering the entire
Hyperloop is large enough to provide an
annual average of 76,000 hp (57 MW),
significantly more than the Hyperloop
requires.
 Battery array at each accelerator, allowing
the solar array to provide only the average
power needed to run the system.

 350-mile trip between Los Angeles and San Francisco will
cost between $6 billion and $7.5 billion compared to $68
billion for high speed rail.
 It will be able to trasport 67,000 people a day.

 Faster
 Lower cost.
 Pollution free.
 Immune to weather.
 Safer
 Sustainably self-powering.
 Resistant to Earthquakes.
Advantages :

 Making a vacuum chamber that long would be a huge technical
challenge, as the pressure of the air outside the tube would push
against the tube with the force of roughly 10 tons per square
meter. That’s a huge amount of force to place on a steel tube with
walls less than an inch thick
 The tube would also have to take the vibration force of a 15 ton
capsule going through it at the speed of sound.
 Merely shooting a few holes in the thin tubing surrounding the
Hyperloop’s vacuum would create air pockets which would trigger
the same kind of cascading failure caused by a crash.
 These extreme speeds would subject passengers to uncomfortable
and frightening forces rendering the system unrideable.

 As it has number of advantages it will very help full for
transport public as well as goods in a very short period
of time (at a top speed of 1220 kmph) and also in lower
cost.
 It is a new concept so there is some future work will be
required for development of this project.
