It's high time we build a motor powered either fully or chiefly by permanent magnets. Alot of people scoff at this and I enjoy scoffing right back. The laws of physics say that energy cannot be created or destroyed. Therefore, there is no such thing as getting energy from nowhere. For some reason there are a good many people who think that a permanent magnet motor is an attempt to violate this fundamental law of physics. I'll say this in a way that everyone can understand, permanent magnet motors do not create energy from nothing, you stupid asshole. Magnets contain, much like all matter, a vast amount of energy. Our goal is to turn one form of energy into another. Likening a permanent magnet motor to a free energy device is like saying that nuclear power plants create free energy from radioactive rocks. So far, every machine that has ever been created has an efficiency of less than 1. That simply means that you never get out what you put in. A machine with an efficiency of 1 would be a machine that puts out the exact amount of energy that has been put in to it, this is commonly referred to as unity. A machine that puts out more energy that what is put in, an efficiency greater than 1, would be said to have overunity. Overunity is not possible, period. Even if something appears to achieve overunity, it really has not. Einstein stated, correctly, that energy is equal to mass times the square of the speed of light. That means that a grain of sand has enough energy bound up within it to vaporize your happy ass in a fraction of a second. The trick, of course, is releasing that energy. Anyway, my point is this; magnetic energy can be experienced by anyone who holds a magnet near a ferrous metal or near another magnet. The idea that one may be able to convert that magnetic energy into motion is not far fetched. Regardless of the failures of the past I content that my ideas will work where others have failed. This is only strengthened by the fact that others who have went in the direction of my designs have abruptly went underground with their work and all but disappeared from the public eye. I, however, plan on a full disclosure of anything I may find. I feel the benefits to to the world far outweigh any personal benefit. So, here is what I have to play with. I have 50 1/4"x3/16" cylinders, axially magnetized. I have 25 1/4"x3/8"x1/16" regtangles, also axially magnetized. 10 1/4"x2" cylinders, axially magnetized. I have somewhere in the neighborhood of 100 1/2"x1/4" cylinders that are drilled and countersunk for 3/16th FHCS. Lastly I have 5 1/2"x1/4" cylinders with a 1/4" hole in them, these are diametrically magnetized. The pic at the top is what I have to work with. Below is a close up of the ones that are countersunk so you can see how nicely done they are. You can look at how the magnets are stuck together and tell how they are magnetized if you don't understand what I mean by axial or diametrically magnetized.
Another great place to get cool parts to play with is old harddrives. You can get them for free in many cases but even when you have to buy them they're cheap as dirt. Salvage drives go for 45 cent a pound in many places. They weigh about a pound a piece, so for $10 you can get 20 hdds. Here are some pics of a couple drives I destroyed today. Some of the cool shit you can get from hdds are really strong magnets, high precision ball bearings and cool electronics stuff. One of the really cool electronic type things you can get are the armatures. Basically the armatures are just an arm that has an electromagnetic coil on one end and a tiny head on the other that reads and writes data to the platter. If you don't know how they work, I'll give you the quick dumbed down version. The coil portion sits between one or two very powerful, slightly horseshoe shaped magnet(s). The amazing electronics on the circuit board deliver varying amounts of electricity to the coil. This interacts with the strong magnetic field provided by the permanents magnet(s), which deflects the armature, allowing it to be positioned above the platter with an amazing level of precision. This brings me to another thing of great coolness, the motor. The motor in a hdd is a bad ass piece of hardware. Not only will it crank many tens of thousands of rpms, it is also encoded so it knows where it is (actually I just found out that it's not encoded, it's a kind of stepper motor! Not the typical kind, but o snap!). By positioning the armature above the platter in a specific spot and then reading the feedback from the motor the read/write head is able to read and write single bits to and from the platter. To get an idea of how amazing this is, just look at the platter. It's about 3" in diameter and stores many gigs of info. That would mean that a single bit is as small or smaller than the sharp point of a stick pin. So, this machine can swing out this armature and pinpoint a single point on a platter that's spinning at 40,000 rpms, then move to another spot and continue reading/writing all so fast that you have time to complain that this damn computer is sooo slow.
The victims.

The armature and it's magnets after removed. Resist the temptation to just rip shit apart. Get yourself a T9 torx tool and take it apart the right way. That way you can use all this cool shit.
The motor. These have some really nice bearings in them, in addition to being cool in the other ways I mentioned.
Tiny, high precsion ball bearings. Sweeet!
HardDrives aren't the only place to get cool parts, printers aint bad either. I recently found an old printer and tore it up hoping to find a couple stepper motors. This particular model didn't have any steppers in it but it did have this, a motor/encoder combo. You can see the disc with the holes in it. that's the wheel of the encoder. Basically, there is a small led that shines light to a sensor. The wheel is in between the light source and the sensor. The holes in the disc allow light to momentarily shine through and in this way the whole assembly is able to know the position of the motor.
Stay tuned to see how to play with really cool shit like this and also how to solve the worlds energy crisis.
