Maglev VehiclesTeam: The ExtremistsScrolls 2112

What is Maglev?High speed rail technology; train is suspended on a magnetic cushion above a magnetized track and so travels free of friction.

It travels at a speed of 400-482 kmph or higher being suspended, guided & propelled on a magnetized guide-way.

History1900s : Ideation of friction less train by Robert Goddard & Emile Bachelet.

1937-41 : Basic maglev concept was introduced.Series of German patents for magnetic levitation trains was awarded to Hermann Kemper.

Technological AspectsThe Maglev works on three basic concepts:LevitationPropulsionGuidance

LevitationPropulsionGuidanceLevitation or suspension can be achieved by:EMS (Electromagnetic Suspension)Earnshaws theorem.Attractive Force.EDS (Electrodynamic Suspension)Repulsive Force

LevitationPropulsionGuidanceMaglev train receives its propulsive force by two methods:LIM - Linear Induction MotorLSM Linear Synchronous Motor

LevitationPropulsionGuidanceSideward forces required for vehicle to follow the guideway.Exactly analogous to Suspension forces i.e. Attractive or Repulsive.Same or separate magnets can be used to provide both lift and guidance.

Consumption of EnergyEnergy is used in:Overcoming air drag.Power is a function of cube of the velocity.Acceleration.Energy required per unit distance is the function of square of the velocity.Miscellaneous works such as air-conditioning, lightning, etc.

EfficiencyPower: Maglev 6 MW, TGV 8MWEnergy: 0.4 MJ/passenger at speed of 480 kmphPassenger fare: Maglev - $0.03/mile, Airplane - $0.15/mileGuideways: No mechanical contact & wear i.e. low maintenanceBulk purchasing of power: Cost reduces to half the cost of residential power ($0.04 - $0.07)

SafetySafety Features:Collision avoidance highest priority.Multiple magnet modules.Sensors for failure warning.Inverters for power failure.Impact protection (Upto 18kmph).

Why maglev?Faster tripsHigh ReliabilityPetroleum IndependenceLess PollutingHigh capacityHigh safetyConvenienceImproved Comfort

ConclusionThe implementation cost for the project was $32M/Kilometer back when the project started but now in this era we can reduce the cost to $12.5M/Kilometer.With the research conducted it shows that maglev is an environment friendly, cost-effective, alternative transportation system with significant public benefits.

Thank you!
