I invented a very hypothetical way of providing nutrients to disaster zones.

You could have the whole wheel quantum entangled and then somehow have the particles borrow energy from quantum uncertainty one way more than the other. Result: extra energy.

It probably won't work, though.

You're right, about the last part.

I have no experience in magnetics or electricity, but I had an idea for generating power with two cylinders with magnets attached to them.

Perhaps I'm just not understanding the donut diagram, but why would this generate power?

The magnetics (shown as sticks) are not only monopolar, they're also unidirectional and facing opposite directions. The magnets therefore repel each other (or attract each other), causing both wheels to accelerate forever.

The energy of the magnets would eventually dissipate due to friction. Also, anything that drew on the energy of such a system would dissipate the energy. It is important to remember that energy cannot be created.

In the real world, I think anything like that would eventually stop moving in a delicate equilibrium. I am curious, though, could it reach a constant speed in ideal, frictionless conditions?

Zero is a constant speed. :P

Okay, I've got it. The invention that will revolutionize life as we know it...

It is important to remember that no magnets are monopoles, and it's even more important to note that even in the event of monopolar magnets there is no way to cause the magnets to have a magnetic field in one direction but not the other.

So this wheel really would not only keep turning but keep accelerating at a constant rate. As long as the deceleration due to work done by the system and friction didn't become greater than the acceleration of the magnets, you could generate not only constant energy but in fact constantly increasing amounts of energy.

You find me the unidirectional monopoles and I'll make you rich!

There are no magnets like this in the real world. The best you can do in the real world is to take a wheel, put in in space near no objects contributing significant gravity, and start spinning the wheel. Although molecular motion might eventually slow down the wheel, you can effectively have a perpetual motion machine as long as it's in perfect isolation.

—Alorael, who also likes the even more fun example of a small wheel rolling around the inside of a circular track. If the wheel rolls fast enough and is in a vacuum, you have a very neat perpetual motion machine. You can also have a slower wheel in a track shaped in any variation of a U shape you'd like.

No. I just tried to come up with the simplest perpetual motion machine that isn't something as boring as a blob rotating in space.

Is there some horrible flaw with these devices from an idealized physics perspective?

If I added a length of coiled copper wire between the two rings...

IMAGE(http://i11.photobucket.com/albums/a181/Alexsticks/magpow2.gif)

...could I generate electricity directly? I don't recall exactly how magnets and copper wire can be made to generate electric current, but I'm fairly certain they can.

EDIT:

And why monopoles? Wouldn't this work?

No. If you do the math and are scrupulously careful to account for the influence of every magnet on every other, you'll find that the forces on each magnet will balance out to zero.

In electromagnetism, you have electric and magnetic fields. Electric fields are created by a thing called charge, a property of a subatomic particle. There is no analog (magnetic monopoles) to magnetic fields, which are created by charges in motion.

The net consequence is that magnetic fields can do no net work, only electric fields can*. You will notice in your design that all the electric fields do indeed cancel. Yes, electromagnetism can be hideously nonintuitive, but that's just the way it is.

To make an electromagnetic motor, you have to spin the magnets with some external force to generate electric currents and set up a voltage. In power plants this is done with the kinetic energy of the turbine. This, in effect, converts kinetic to electric energy. Since magnetic forces can do no work by themselves, it is impossible to convert "magnetic energy" into electrical energy.

* Work is defined as the dot product of force and distance. In the dot product, only the parallel component counts. The magnetic force always acts perpendicular to the direction of motion. Perpendicular components of the dot product will go to zero, hence no work.

I can't believe that I forgot to mention it, but I invented a device to retrieve snacks that get caught in vending machines. I also do some work in a robotics lab, where I'm working on a automated paintball shooting tank. It autonomously tracks targets and shoots them. The robotics club intends to use it to control the squirrel population on campus.

I have just thought of a better way of creating energy through use of a wheel. Gerbils or large rats. Whenever one gets tired put another one on.

Because the squirrels are evil and need controlling in the first place. This may also make them a little bit useful.
