Benefits

No fatigue Self-parking Reduce lane widths

Ultra High Speed Trains

Main limiting factor in speed is friction Sources: air resistance and rolling resistance Vacuum tunnels and magnetic levitation (MagLev)

UDLS, November 23, 2012 Future Transportation

slide-16

SLIDE 16

Speed and Energy

Speed could be in excess of 5000 km/h Sound barrier, but no sonic boom Energy only used for acceleration and retardation

MagLev Trains

Two in operation: Shanghai (China) and Mizayaki (Japan) Can be electromagnetic or electrodynamic

SLIDE 18

Electromagnetic Suspension (EMS)

Underside of train has large C-shaped electromagnets Repelled by the steel underside of the track Levitates by around an inch

UDLS, November 23, 2012 Future Transportation

slide-19

SLIDE 19

Electrodynamic Suspension (EDS)

Magnets on both the train and the track underside Levitates around 4 inches

UDLS, November 23, 2012 Future Transportation

slide-20

SLIDE 20

EMS vs EDS

EMS systems require less magnetic fields EMS are less stable and need constant monitoring EMS also function at low speeds EDS are more stable due to presence of multiple magnets Need to be shielded, else would affect pacemakers

Vacuum Tubes

Air resistance prevents MagLev’s from going faster than 600 km/h Vaccum tubes: large, hollow tubes that MagLevs can travel in Partially evaluated tunnels are useful to

SLIDE 22

Problems with Vacuum Tubes

Expensive to build Maintaining a vacuum is expensive; proposals have suggested a global, interconnected network of tubes Depressurizing chambers on either end to allow vehicles to gently normalize pressure Single points of failure and attractive terrorist attack sites

What about Space?

Even more desperately in need of an overhaul Space elevators and Loftstrom loops are possible future plans Too lazy to talk about them today
