    Extractions: Original by Philip Gibbs and Andre Geim, March 1997. A theorem due to Earnshaw proves that it is not possible to achieve static levitation using any combination of fixed magnets and electric charges. Static levitation means stable suspension of an object against gravity. There are, however, a few ways to levitate by getting round the assumptions of the theorem. In case you are wondering, none of these can be used to generate anti-gravity or to fly a craft without wings or jets. The proof of Earnshaw's theorem is very simple if you understand some basic vector calculus. The static force as a function of position F x acting on any body in vacuum due to gravitation, electrostatic and magnetostatic fields will always be divergenceless. div F . At a point of equilibrium the force is zero. If the equilibrium is stable the force must point in towards the point of equilibrium on some small sphere around the point. However, by Gauss' theorem, F x ).d

    Extractions: Maglev (Magnetic Levitation) is a new mode of transport, in which high speed vehicles are magnetically levitated and propelled along elevated guideways. Maglev can transport passengers and freight over long distances at speeds of hundreds of miles per hour. Maglev promises to be a major mode of transport in the 21st Century, even more important than autos, trucks and airplanes. Maglev 2000 is developing and implementing this new mode of transport. The M-2000 system is an advanced second generation maglev system based on recent inventions by Gordon Danby and James Powell, the original inventors of superconducting maglev. The M-2000 system is low-cost, includes freight transport, and is capable of high speed (300 mph) electronic switching.

    A introductory questions and answers on Maglev technology, including several relevant links.  
    http://www.o-keating.com/hsr/maglev.htm
    
    Extractions: The principal of a Magnet train is that floats on a magnetic field and is propelled by a linear induction motor. They follow guidance tracks with magnets. These trains are often refered to as Mag netically Lev itated trains which is abbreviated to MagLev. Although maglevs don't use steel wheel on steel rail usually associated with trains, the dictionary definition of a train is a long line of vehicles travelling in the same direction - it is a train. A maglev train floats about 10mm above the guidway on a magnetic field. It is propelled by the guidway itself rather than an onboard engine by changing magnetic fields (see right). Once the train is pulled into the next section the magnetism switches so that the train is pulled on again. The Electro-magnets run the length of the guideway. Well it sounds high-tech, a floating train, they do offer certain benefits over conventional steel rail on steel wheel railways. The primary advantage is maintanance. Because the train floats along there is no contact with the ground and therefore no need for any moving parts. As a result there are no components that would wear out. This means in theory trains and track would need no maintanence at all. The second advantage is that because maglev trains float, there is no friction. Note that there will still be air resistance. A third advantage is less noise, because there are no wheels running along there is no wheel noise. However noise due to air disturbance still occurs. The final advantage is speed, as a result of the three previous listed it is more viable for maglev trains to travel extremely fast, ie 500km/h or 300mph. Although this is possible with conventional rail it is not economically viable. Another advantage is that the guidway can be made a lot thicker in places, eg after stations and going uphill, which would mean a maglev could get up to 300km/h (186mph) in only 5km where currently takes 18km. Also greater gradients would be applicable.

    Extractions: Magnetic Levitation Emerging Technologies By Nick Presson Magnetic levitation has been around for years, but with advances in technology it may become a part of everyday life. The main emphasis for magnetic levitation is for transportation. Magnetically levitated ground transportation, or “Maglev”, is an advanced mode of surface high speed transportation whereby a vehicle gliding above a guideway is suspended, guided, and propelled by magnetic forces. Can you imagine a train that that actually floats in air 4 to 6 inches in the air and travels up to 300 mph. This technology can reduce air and highway congestion, air pollution, and petroleum use. The transportation system in the United States has been much admired around the world. Our extensive highway and air systems have facilitated business and leisure travel and contributed to a high quality of life for many Americans. In 1990, 429 million passengers traveled 342 billion passenger miles on commercial airlines. Americans traveled 2 trillion passenger miles my car, truck, bus, and public transit, and 6.1 billion passenger miles on Amtrak.

50. Inductrak
    Passive maglev technology developed by a Livermore team.  
    http://www.llnl.gov/str/Post.html
    
    Extractions: FOR the past two decades, prototype magnetically levitated (maglev) trains cruising at up to 400 kilometers per hour have pointed the way to the future in rail transport. Their compelling advantages include high speeds, little friction except aerodynamic drag, low energy consumption, and negligible air and noise pollution. However, maglev trains also pose significant drawbacks in maintenance costs, mechanical and electronic complexity, and operational stability. Some maglev train cars, for example, employ superconducting coils to generate their magnetic field. These coils require expensive, cryogenic cooling systems. These maglev systems also require complicated feedback circuits to prevent disastrous instabilities in their high-speed operation. Lawrence Livermore scientists have recently developed a new approach to magnetically levitating high-speed trains that is fundamentally much simpler in design and operation (requiring no superconducting coils or stability control circuits), potentially much less expensive, and more widely adaptable than other maglev systems. The new technology, called Inductrack, employs special arrays of permanent magnets that induce strong repulsive currents in a "track" made up of coils, pushing up on the cars and levitating them. Totally Passive Technology During the past two years, a Livermore team, headed by physicist Richard Post, has successfully demonstrated the Inductrack concept in test trials. The test runs demonstrated the system's totally passive nature, meaning that achieving levitation requires no control currents to maintain stability, and no externally supplied currents flowing in the tracks. Instead, only the motion of train cars above the track is needed to achieve stable levitation. The results have been so promising that NASA has awarded a three-year contract to the team to explore the concept as a way to more efficiently launch satellites into orbit.

    Promotion of the adaptation of monorail technologies for maglev  
    http://www.monorails.org/tMspages/MagMono.html
    
    Extractions: A new breed of monorail is being developed. It is still a young enough technology that there are more questions than answers. How capable is it and is it too expensive to build? There is currently great interest in maglev. The Monorail Society recognizes the great progress that maglev developers have made in recent years. We look forward to seeing maglevs in operation so promoters will have a chance to back up their claims of maglev's advantages with statistics from real revenue operations. Will maglev prove itself to be an economic success and change ground transportation? We should have the answer in the 21st Century. While the story unfolds, we are watching with great interest. While The Monorail Society 's main focus has been on the promotion and appreciation of proven monorail technology, ignoring maglev because it follows the guideway differently would be a mistake. Within these pages The Monorail Society focuses on maglevs that share the same characteristics as monorail, hence our title "Maglev Monorail." While some of the tracks for maglev are much wider than many monorails, the trains that run on them are wider than the guideway, and therefore meet the criteria of our definition of monorail. Are those tracks too wide for public acceptance? That remains to be seen, and we won't shy away from discussing potential negative aspects of the mode as well as positives. The promise of trains with aircraft speeds in safety is very enticing, perhaps maglev monorail's time has come.

    Many hurdles before maglev is able to get off the ground.

    Extractions: Many hurdles before maglev is able to get off the ground Sunday, March 7, 1999 By Joe Grata, Post-Gazette Staff Writer How the maglev shuttle might look. (Credit: General Atomics) As long ago as November 1996, developers of maglev told public officials they were ready to start building. Maglev, which uses powerful electromagnets to "float" and power people-mover cars along an elevated guideway, is a two-part proposal. One part is the Civic Arena Shuttle System, a $147 million, 2,200-foot demonstration project tied into a 5,000-car parking garage behind the Civic Arena. The other part, a follow-up to CASS, is the Pittsburgh Airborne Shuttle System, 10 miles and $550 million of extensions to Oakland and the North Shore. "We’re at a crucial juncture" for both proposals, O’Loughlin now says of the deadlines and demands coming down on the nonprofit corporation he formed with two friends in 1992. "We shouldn’t lose this opportunity. It’s too important to Pittsburgh." A Pittsburgh Post-Gazette review of the finances, technology and other aspects of the maglev project found the track remains riddled with obstacles, including reluctance by the Port Authority to join WPMD as a public partner for PASS, and the lack of city support for CASS.
