Drawbacks of existing transportation
Safety
Dependence on Oil
Low Speed
Less Efficient
Negative impact on nature
Evacuated Tube Transport:Introduction
It is a maglev train running in vacuum tube with the help of guide ways.
A car sized capsule(2 feet in dia.) runs in tube of 1.5m dia.
It has high velocity, low noise, energy efficient, low pollution and high security.
ETT is more beneficial and promising than any other existing railway, highway or plane.
The Maglev
Levitation of maglev train(8-10mm)
Attraction of similar poles : acceleration
For braking : voltage cutoff of electromagnets
Tube
Circular tube
Composite structure of stainless steel and concrete
Stainless steel thickness: 2-4mm
Vacuum creation in tube
Vacuum pump installation every 3-5 km
Isolation gates are used
Among recent, Root pump are used to pump out the air because of high pumping speed, simple and low cost
Gas leakage detection is done by closing isolation gates and observing vacuum guage
Ultrasonic detecting is also applicable
Features
High speed
More efficient
Less noise
Safety
Minimum pollution
Independent of weather
No intervention of birds, animals
Reduce in oil consumption
Job creation
Conclusion
ETT is simple, high speed, safe and secure, less harmful to environment.
Most efficient than any existing transportation system
ETT will create expanding potentials for several generations
