Electromagnetic levitation

But would require a serious redrafting of the laws of physics.

Probably not. Anybody who knew enough physics to know what to steal would be laughing too hard to be in a position to steal anything.

Since "the World" in question would be in another dimension running with a different set of phsyical laws, nobody around here could have a useful opinion.

No, it would comply with Maxwell's electrodynamics.

There are other physical laws, including "for every force there is an equal and opposite reaction". If you want to levitate a house, the reaction mass is going to be the rest of the planet.

-- Bill Sloman, Nijmegen

Yes, so the invention must use other reaction matter which is mass-less but still has inertia.

Here is one someone else built:

Unfortunately I concluded that according the supplied theory it should turn the opposite way to what the video demonstrate. So, I think is is a hoax.

Harvested in cloud-cuckoo-land. Light can be seen as massless, but photons have energy and and - as Einstein pointed out - energy is mass, so photons do have both mass and inertia.

-- Bill Sloman, Nijmegen

Yes, perhaps, and to levitate an entire vehicle's (any mass in deliberated motion) weight, it would require a huge amount of energy just for the levitation. That would be a HUGE power source and its weight, added to the vehicle, THEN huge amounts of energy have to be generated to get it moving, and then again to stop it. All requiring precision and safety, of course.

It doesn't matter how easy it remains moving once you start it. You cannot leave out the details of safe travel requisites. This ain't bumper cars.

You have gained nothing. Four wheels on bearing fitted axles works just fine, and uses far less energy. That is about as simple as the math can get. More weight or bigger "vehicle"? add wheels.

Look at your hard drive spindle.

Air levitation works. E/M levitation works, but is only practical for a few purposes. A solenoid is one such form factor where EMF is used to force a mass in a particular direction.

Items like trains work as well, because they are large enough platforms to support the power sources need to generate the force, and because other elements can be incorporated into the track. That will not work for cars, because greedy bastards want money for everything, so free car levitation coils in the road will not be happening.

No different than if you use a crane to lift one (a house). The crane applies a reaction force to the ground (the rest of the planet).

You are the opposite force to intelligent thought.

I think it should not be more than in magnetic levitation such as used in Siemens maglev trains. I may be wrong but I am setting up some experiments to see if my concept works at all.

Interestingly, more things in nature abhor a magnetic field and try to get out of it. See "Levitated Frog" video, where living flesh is 'floating' in a 3T field [from memory] Only a few items in nature are attracted into a field.

Most of the energy spent in creating intense fields is spent in just that, not doing any actual work.

I believe the Japanese have created 300+T fields for short periods and they report some really weird things happening there.

No, no, read again: "MAGIC black-box" No need for physics... ;)

Earthquakes and tsunamis? ;-)

Congratulations. You correctly recognised the reference.

st of the planet.

Is that your proposal for an "electrically powered magic black-box with force which generation does not require reaction mass" ?

The planet may not mind providing the reaction mass, but it is required in the set-up.

They had both - repeatedly - before they had 300+T transient fields.

The problem with making cars float is that there would be a LOT more 'collisions', and they would epitomize the very meaning of the term. Floating a mass is easy. Controlling it once you have levitated it would be pretty hard. Maglev trains have guide-ways to keep them in line and over the float coils. We would not be able to do that with roadways.

The same thing that causes the rolling resistance that takes up some gas is the very thing that makes them safer than say flying machines. Weretheair filled with folks lolly gagging about in small aircraft, a lot more 'accidents' would happen.

Hell, we should do that for the population reduction effect alone, eh?

Maglev relies on a vertically directed force to keep the train floating. The same technology produces laterally directed forces to keep the train directly above the track - the guideways are just a fail-safe precautions.

Roadways could be engineered with multiple maglev tracks to deal with multiple parallel streams of cars. Switching between streams would require some complicated structures in the road, and complicated control gear, but it's not impossible.

Perhaps not. Maglev could be interesting, but would take a huge capital investment.

-- Bill Sloman, Nijmegen

Please note that the levitating engines can act also in any direction which with use of accelerometers and control electronics can make perfectly stable and predictable motion. One could easily make it as unconnected floating steps up on which human could clime up the sky. Also it would have perfect brakes as the deceleration could be precisely controlled.
