Plasmagnetic Levitation Theory: Hoverboard

Post stuff here pertaining to non-spud related projects that many forum members seem to enjoy. Hovercrafts, dirt bikes, electronics, propane-powered bikes, go-karts, etc. This is more of a project area,
not a place to chat about what you saw yesterday on TV. Remember to keep it within the forum rules!

How the Technology Works

Invented by software engineer Bill Butler, Plasmagnetic Levitation is based on the fact that an alternating magnetic field will repel a non-ferrous conductor. So by turning the air under the craft into a conductive plasma, and inducing a magnetic field into it, the resulting force of repulsion between an onboard magnet and the magnetized plasma, should levitate a vehicle over virtually any surface according to Lenz's Law.

In a conventional maglev system, onboard magnets interact with magnets in a track to levitate a train either by magnetic repulsion or attraction. One of the drawbacks of this approach is that levitation height is limited by the inverse square law. Plasmagnetic Levitation gets around this limitation by creating "stacks" of current loops in the air underneath the vehicle. Theoretically, this would allow a vehicle to reach hover heights limited primarily by its own stability.

Here it is simplified...The plasma is created by shining a ultraviolet lamp in the air. The plasma is columned by the electromagnet and a current is ran through the plasma. The electromagnet is the negative end. The plasma is the positive end. You know what that means...REPULSION!..Meaning hovering!

The only thing I'm doubting is making the plasma. Will the UV lamp actually produce plasma columned by the electromagnet? But the electromagnet repulsing from the plasma is true since it's Len'z Law.

I'm going to test this and make a small scale version hoverboard using this theory.

Anyone have a plasma lamp?

You can test this theory by making an electromagnet (connect wire to a flashlight battery to the + and - then coil around a nail) and hold the electromagnet over the plasma lamp. If it works notify me.

well i dont claim to be a physist, but it seems to me that uv energy required to make a large nough *cloud* of plasma to provide a sufficient force to be repelled against would draw far too much energy to be suported by thecloud of plasma.

The "energy" isn't supported by the plasma. The plasma is supported by the "energy" or generated by the UV "energy".

What pbmann is trying to say is that the board wouldn't be supported by the plasma because the energy required to make it is far too great.

Ohhh. The photoionization? You can control the energy by the type of battery right? The photon gets it's energy from the electromagnet's electron volts. So if the electron volt is too high, you can lessen the voltage by lessening the coiled wire.

To ionise hydrogen you need 13.6 electron volts. Hydrogen has a 91nm wavelength.
So to ionize ultraviolet light you need _____ electron volts. Ultraviolet's wavelength depends on if it's near, far, vacuum, or extreme.

More like he is trying to say that all the batteries or chemicals or watever that will creat the power for these electromagents will be too big for the electromagnet to hold up.

You guys, it's a rocket, plain and simple.

"based on the fact that an alternating magnetic field will repel a non-ferrous conductor"
That doesn't, obviously, apply to the ground. The plasma is conductive, it repels the plasma, and you get thrust. He admits this over and over again...

You ionize the gas (WTF does hydrogen have to do with it? He's talking about air) using the UV light. This UV light has to be at or above the ionization energy, as you said, and should coincide with an absorption band of the gas.
The electromagnet has nothing to do with it. It simply repels the plasma once you have it.

My conclusion that there are MUCH more efficient methods of generating lift. Such as the typical hovercraft mechanism, propellers, jet engiens, even other methods of repelling the plasma.

Like most sci-fi like concepts, everything is sound except for the question of energy supply. Short of a thermonuclear reactor, I dont see any possible way that a craft could supply enough energy to lift itself in this manner. This is the same problem as with ionic wind levitators: they work great, as long as they dont have to lift their own power supply.

On a side note:
I once farted, passed out, and traveled through a a rift in the space-time continuum. There, I learned how to separate fact from fiction, and discovered my feminine side. I slapped that bitch back to the Stone Age, and was thereby banished from Never-Never Land and extradited back to Reality.

Dr, glad to hear your feeling better and back to your old *cheery* self.

What i was trying to say is that you make you plasma, repell away from it, if it doesnt displace enought air, or has a density lesser than air you're going to A) repell your plasma down to earth, fallontop of it and have a flourescent tube sticking in your as, and you tities playing dixie on the spokes. or b) your going to repell off your plasma, but also repell it away from you, make a vaume and fall, remake more plasma relell it awayt and fall some more. I guess i amassuming you cant make a really dirrectionalized magnetic fiel which will make it a column, extend down to Dr's institution and reak havoc with his martian communicator, and then propell enough of it down onto it self to lift your up.
