I have made an experiment.I attached a longplay disc to a small engine and I started the engine. It appeared that it is hard to move the longplay disc along the rotation axis, and as far as I know it is the reason why the bike wheel doesn't fall. It is harder to move it along the rotation disc then moving perpendicular to it.
Why not move a disc forwards along the rotation axis and backwards perdpendicular to it. Wouldn't that create some "resistance" in one direction and none in the other. That is how an inertial propulsion can be made.

You can make a simple gyroscope by spinning a bicycle wheel.

Movement forward, sideways, or at any fixed angle should be the same.  Does wind play a role?

It takes increased force to twist it.

I would guess that twisting the gyroscope would change the speed of rotation.  And, since no rotation gives no resistance, and the resistance to twisting increases with the speed of rotation, that you would actually slow it down slightly by expending the energy to twist it.

If you hold your bicycle wheel on one finger (causing a horizontal twisting), it will slowly precess.  Again, I believe this precession is due to converting rotational energy to precession.

hey guys. i have an idea for what you mite call perpetual motion. (i didn't see any suitable forums so i went for the "nerdy one").

It is based on the idea of a superconductivity. Superconductivity is a property of super conductors. super conductors are compounds (usually crystalline) that don't form any kind of resistance. in-fact, it has been proven that you can observe electricity running in a loop of super conducting material, and not loose any energy.

A common application of superconductors are in MRI's, where they are used to produce momentarily "super charged" electromagnets. though there is still something that i have left out, and you are probably wondering it to: why are superconductors not use for every electrical connection.

the problem is that superconductors require cooling to around -197 Degrees Celsius. Which requires a lot of liquid nitrogen.

but back to my theory.

Of you can create mass amounts of electromagnetism to power an MRI, why not use it to power an electric motor.
it's simple, put some power into the two electrodes, and as i where: "stick them together and see what happens!".

there's no reason why it cant be done, but why isn't it being done.

P.S. i have already patented the idea (suckers).

Where is the "reactionless" part of the invention?

[Yusup Hizirov]

Movement is rotational and circular, this circular motionless movement.
Still on YouTube, I did not see a really working propeller. And this one is still doing work.

Movement is rotational and circular,

That's not an example of reactionless propulsion. It's well understood that you can change the orientation of an object without expending propellant. Gyroscopes can do it just fine. It's all well in line with Newton's laws.

this circular motionless movement.

"Motionless movement" is an oxymoron.
