I started working on this project about a month ago. This concept was hatched from my work with the MEG. I realized that in order to generate any power, there had to be some movement associated with the device.
Like any new idea, the concept and realty have to be reconciled through construction and testing. This takes a lot of time and energy. Nevertheless, preliminary results are encouraging so I thought I would share what I was working on.
A neodymium magnet is nothing but a perpetual energy device, but getting power from it without wasting a lot of energy is not always easy. I think the trick is efficiently turning the magnet “on and off” in order to use it. To do this requires a way to recover the power used in switching.
A transformer is exactly what is needed. A transformer orients the magnetic domains in its core depending on the polarity of the current traveling through the primary winding. This energy is then transferred to the secondary winding in a highly efficient manner. A bifiler wound coil fits the bill nicely, although adjacent coils will also work.
All I am doing with the switching coil is reorienting the domains of the core in opposition to the magnet. This essentially turns on the magnet by blocking the flux path between poles. The only work being done by the switching coil is in the hysteresis loss. All the rest of the power used in the coil is available for recovery.
I have two devices that I’m currently working on. One is a solenoid and the other a rotating unit. The solenoid is very interesting to me, although the rotating device will ultimately be far more efficient.
I have tried a number of configurations for the solenoid. I tried a coaxial configuration similar to the Hilden-Brand electromagnet, but it didn’t switch efficiently (see below).
Moving the control coil 90 degrees, and closer to the magnet, helped actuate the core.
As the core is pulled into the magnets it becomes polarized. The act of a polarized core traveling past a coil will generate power. If a coil is wound around the core just outside of the solenoid, power can be collected. I haven’t got quite that far yet, but it’s the next step.
Eventually I plan on having two solenoids set up in a pull/pull configuration with a common core. Between the two solenoids I’ll place a pickup coil around the core. How much power it will generate is yet to be seen.
Power is also generated in the steel surrounding the poles of the magnet. Current is induced back into the switching and recovery coils as a result of the movement of the polarized core. How much is also yet to be determined.
Here is the front with the core in:
Here is the center without the core:
There is still a lot of testing and development to do but I have a fairly solid idea of what I want to end up with. The solenoid could be used as part of a motor, or a small generation unit, but I think a fully rotating device (still working on it) will be better. I'm going to try and get this solenoid to oscillate using a mechanical switch and a spring, although electronic switching will probably work better in the long run.
There are hundreds of ways to reconfigure this type of device. I think of a new way almost everyday, but I have to stick to something. I think the concept has great potential so I'll be traveling down this road for a while.
Cheers,
Ted
