Hyperloop is the new mode of transportation after air, water, rails and roads. It could be a realistic high speed as well as economical way of transportation apart from a fantasized means of transportation called the "teleportation".
3. INTRODUCTION
The intent of the project was to develop the fastest
mean of transportation which would transport
passengers at a remarkable speed of 1220 Km per
hour.
The existing modes of
transportation
including air, rail, road
and water are either
expensive or slow or a
combination of both.
6. PROPULSION
Based on the same principle as maglev.
Gives the right amount of starting acceleration to the
capsule.
Consume an average of 21MW which is generated by solar
panels.
7. TUBE
Contain capsules.
Made of steel which ensures ease of build because they can
be welded easily.
The tube ensures reduction of shock waves generated due
to travelling at a very high speed.
8. CAPSULE
Carry passenger as well as vehicles thus two capsules are
build:
a) Passenger only mode.
b) Passenger plus vehicle mode.
Can Carry 28 passengers at time.
Frequency – every 2 minutes
9. COMPRESSOR
Most important part.
Helps to reduce air drag.
Concept:- aerodynamic drag increases with square of speed
and power requirement increases as cube of speed
INITIAL FINAL
SPEED: ‘x’ SPEED: ‘2x’
AIR-DRAG: ’ y’ AIR-DRAG: ’4y’

11. PYLONS
Tall tower-like structures.
Prevents earthquakes by thermal expansion and dampened
lateral slip.
Low land requirement.
12. AIR BEARINGS
Air from compressors is passed on to air bearings.
Speed of Hyperloop is magnificently increased because the
friction is drastically reduced.
Similar to air hockey table.
13. CHALLENGES FACED
CHALLENGE 1: Kantrowitz limit
The speed limit for an object passing through a tube, at the point where the
air in front of the object kind of bunches up and can no longer flow around
the object.
SOLUTION:
Whenever we have a capsule moving at a high speed through a tube
containing air, there is a minimum tube to capsule area below which we will
choke the flow What this means is that if the walls of the tube and the
capsule are too close together, the capsule will behave like a syringe and
eventually be forced to push the entire column of air in the system, which
isn’t good.
14. The approach that we could use to overcome this Kantrowitz limit is to mount
an electric compressor fan on the nose of the pod that actively transfers high
pressure air from the front to rear of the vessel this is like having a pump in the
head the syringe actively releasing pressure.
CHALLENGE 2: FRICTION
There is another problem simultaneously to solve, this is how to create a low
friction suspension system when travelling at over 700 mph.
SOLUTION:
Wheels don't work well at that sort of speed, but a cushion of air does. Air
bearings, which use the same basic principle as an air hockey table.
We can use vacuum to totally reduce air drag but it is not possible to create
vacuum for so long distance so tubes are filled with low pressure air.
15. CHALLENGE 3: POWER
SOLUTION:
The pod will be propelled with the help of magnetism.
Now magnetism requires electricity.
This electricity will be provided by solar energy. Hence the Hyperloop promotes in
green technology transportation too.
Solar panels will be along the tube i.e. on top of the HYPERLOOP.
These panels will generate 120W per sq. meter.
The average energy generated will be 57MW per year which is more than the
HYPERLOOP will use.
19. CONCLUSION
With the increase in population and pollution, there has been a
thriving demand for a technology that not only revolutionizes the
world with its speed but also keeps in mind the impact it imparts
to the environment.
Hyperloop could be the cleanest, fastest, cheapest and the latest
means of transport.
The development in this new venture is encouraged by the very
fact that it is open-source.
