The Magic of Magnetic Levitation
James D. Livingston, Central, 538 L786r 2011
Not very technical. Describes Earnshaw's theorem by fiat, not really explaining it. Some pretty pictures.
- p091 Fig 14: diamagnetic levitation of a thin graphite squar above 4 NIB magnets. Centimeter scale.
- p097 Fig 17: Andre Geim's 1997 levitating frog, 2000 !igNobel Prize. 2010 Nobel for graphene research.
- p110 Flux Pinning in Type 2 superconductors allows more current flow. Doesn't mention London depth.
- p126 Leviton Ion AG (antigravity) Globe. Amusing, reviews on Amazon suggest it is not robust or easy to use.
- p147 Fig 27: Ahmadinejad touring the Natatz isotope separation centrifuges. Designed by Austrian Gernot Zippe in the Netherlands, copied by Pakistan and then Iran. Vertical shiny metal cylinders wrapped with a spiral of tubing, perhaps coolant. They look two meters tall and 30 centimeters diameter in a one meter grid. They contain a carbon fiber rotor on magnetic bearings centered on needles.
- p157 describes Boeing 5kWh/100kW flywheel with a YBCO ( yttrium-barium-copper-oxygen ) superconducting bearing
- p191 Fig. 34 Emile Bachelet's prototype maglev train, 1914 London
- p196 Transrapid EMS maglev train experiments, controlled atractive levitation with linear synchronous motor to permanent magnets on vehicle wrapping under the track.
- p198 TR05 to TR07, 31.5 km test track with end loops, 413 km/h in 1988.
- p202 Henry Kolm and Richard Thornton at MIT Natoina Magnet Laboratory, 1/25 scale 60 mph in 1974. Scientific American article in 1973.
- p206 Fig. 37 Japanese MLU002
- p208 TGV Train a Grand Vitesse 279 km/h scheduled trips, 475 km/h test train.
- p220 Fig. 38, Transrapid maglev from Shanghai to Pudong International Airport, 30 km in 8 minutes, maximum speed 430 km/h
