Additional documentation
This was supposed to be a mount used to attach our fan compressor blade to the motor. We were not able to get it made from a 3D printer due to the size of it being extremely small and detailed. In the end though it wasn't need since we could get or blade to spin in the first place. :P

The first three pictures in the slideshow above are the general materials required to build the prototypes that we built. Those materials are, neodymium magnets, a motor, and a rotating assembly such as a fan blade. The fourth picture is an example of the magnetic fields effecting each other. There are three magnets placed on the right side of the glass container and only one magnet on the left side. This creates a much bigger magnetic field on the right side of the glass container and there fore attracts most of the iron particles. The last four pictures are our prototypes that we built. The first one involved using a simple computer cooling fan with a built in motor and magnets. This didn't work, and we thought that the reason why it didn't work, was because the motor in the cooling fan was effecting the magnets next to it. So our second prototype involved building a separate rotating assembly away from the motor to eliminate the effect that the motor has on magnets. This however didn't work either. So the next prototype involved using a wheel to help get a flat surface on the outside of the rotating assembly to help further increase the magnetic fields being effected. It basically came down to trying to get the prototypes to spin. Eventually we found out that we needed an electromagnet to actually get our prototype to properly work, but that goes against our goal to not put any energy into the system and only get energy out. And trying to control the voltage that goes into the electromagnet was very hard to do with the limited materials that we had. So in the end, the prototypes didn't work.
