    Well, it was a monorail. I don't know if monorails use magnetic levitation. Also, famously, the full episode that Conan O'Brien wrote. (He contributed to a bunch of other scripts.)

    If you've played Riven, that's riddled with maglev devices.

    ETA: I knew I'm not making this up: Maglev . I saw a mention of the Tobu-Kyuryo Japanese one in the news quite a while back when it started service.
    I've been on a Maglev train once. There's this test track in Germany. You know what would be even better. If you placed a maglev train in a vacuum tunnel you wouldn't even have any air drag, making the train even faster, and energy economical.

    So I know that there are ridiculously smart people on here who can probably help me out with this idea, and tell me whether it is possible, probable, or if it is an idea that can be manipulated for some kind of use.

    We all know how the opposite polar ends of a magnet attract, and the similar ones repel. Well, I was thinking, can we use the repelling magnetic forces to create an efficient transportation system?

    I suppose the basic idea would be laying a magnetic sheet in the ground, with a certain amount of magnet on the bottom of the vehicle (or object) in question. Then I figured that the height it would rise off the ground could be determined by something weakening the magnetic force and lowering it, or somehow multiplying the force and rising it.

    As a sub idea, it could make the use of chair legs, table legs, shelves to a certain extent, etc obsolete, minus the aesthetically pleasing reasons.

    It could be just some crazy idea, but it just kind of came to me one day and I was hoping that some of the intellects on here could tell me the flaws or provide better ideas.
    I like this idea a lot. I came up with something similar when I was little. The problem I always encountered was that the opposite magnet would always throw the other one completely away as soon as they weren't being held together, and I couldn't figure out how to design something that would allow one to push the other away a little, without giving it enough room to be pushed away far enough to fall to the ground affected by gravity.

    I actually came up with this idea when I was in the fifth grade and only recently started seriously thinking about it, now that I understand fully what cars run off of and what it does to our environment. I really would love to have such an efficient system for transportation and I am always sitting in wonder as to why people don't think of doing something like this.

    And from the talk of maglev trains, it looks like I should look into it more. The idea of the vacuum tunnel is a good idea. Now there are going to be little plans for designs littering the house

    I think they often do, but then they figure someone else has already tried it, or is already working on it, so they just let it slip through their mind.

    There's probably a lot of untapped creative potential in the general population, honestly.

    Maybe if everyone collaborated with the different strengths and weaknesses, and different kinds of intellects, we could actually get something done.

    God forbid, it sounds like an organization!

    That's what I want. I want an organization to create something revolutionary.

    The solution that is employed quite often is to have the base or the floater constructed of a varible electro-magnet. You may have seen such novelty items a a globe with a small magnet under the north pole that floats freely in the concavity of a crescent shaped frame. you can reach over and gently spin the globe and it keeps going a very long time just floating in space.In the top of the crescent is an electro-magnet (coils of wire wrapped around a metal center. The exact voltage needed to create just enough pull is regulated by an IC circuit that gets feed-back from sensors along the inner curve.

    The economic issue is that to levitate a substantial weight requires substantial electricity, and the key technology that can make it cost effective is high temperature super-conductivity. High Temperature meaning room temperature.

    When electrons pass through a wire at normal temperatures the thermodynamic vibration of the atoms eat away at your lot of electrons and start vibrating faster (getting hot) this makes the loss worse and can light your bulbs. However, the power or battery company expects you to pay for those electrons. Yet when you get near absolute zero (0K) or minus 476 degrees C, the electrons pass unimpeded through the wire like throwing a baseball in outer space. No loss of electrons, no power bill. Labs around the world are working on alchemical compounds that remain SC at higher and higher temps. But the philosopher's stone remains to be found.

    I hate to play the card but, you know...

    I am starting to feel rather unoriginal. It is rather deppressing to see my ingenuity diminished like this.
