Magnet Myths and Misconceptions

I really do not think that this conductive path keeps jumping back up to reposition itself. This path between brushes would remain constant-no movement. That is like saying a light beam would bend if we spun a flash light around fast enough-just not going to happen.

You could be right about that Tinman.  But I find that induction in some form is always involved on the disk to create electrical charge on the disk from the motion and magnetic field.  It's more of a matter of how that separation of charge is tapped.  On the Faraday generator, he used a magnet on the area of the disk where the brushes were located (not on the rest of the disk), but as soon as the electrical potential on the disk escaped the magnetic field, it acted like an eddy current, and dissipated as loss and heat on the disk.  Tesla solved this by using a magnetic field on the entire disk to keep the charge separated.  Enjoyed the discussion and hearing others views.

Copper is nice because of its low resistance, and resistance is what kills homopolar dynamos. After all, when your generator voltage is only one or two volts maximum, it doesn't take much resistance to cut the current to nothing, even if there is a _lot_ of power available. But you don't have to use copper, you can use aluminum, it will work almost as well.
But there are plenty of torque-rpm graphs already available in the DePalma-Tewari work.

I wonder if anyone has tried to use an inverter circuit to step up the voltage output right off of the generator output?  Seems like it would cut low voltage loss to only inverter loss.

Quote :

"The other two describe how the fields "circulate" around their respective sources; the magnetic field "circulates" around electric currents and time varying electric fields in Ampère's law with Maxwell's addition, while the electric field "circulates" around time varying magnetic fields in Faraday's law."

"Maxwell's addition to Ampère's law is particularly important: it shows that not only does a changing magnetic field induce an electric field, but also a changing electric field induces a magnetic field."

While Maxwell's equations (along with the rest of classical electromagnetism) are extraordinarily successful at explaining and predicting a variety of phenomena, they are not exact, but approximations. In some special situations, they can be noticeably inaccurate. Examples include extremely strong fields (see Euler–Heisenberg Lagrangian) and extremely short distances (see vacuum polarization).

   In a circular particle accelerator they use magnetic fields to keep the charged particles from hitting the walls.  They accelerate them using efields and direct them by using bfields.    In copper there are a prime number of protons in the nucleus shielded by a large number of electrons in lower energy shells. The valence shell is always looking for electron pairs.  The atom is electrically neutral with it's 29 electrons and protons but due to electron pairing wants to loose one electron or gain one electron.  This makes for a good conductor as it is easy for the atom to give up an electron to a neighbor. The neighbor has eight and the donar 6.  The donar has a hole and the neighbor an excess electron.   An external force will easily overcome the pairing bond and move the excess electron to the atom with a hole.  This makes the electrons move in one direction while the holes move in the other.  To overcome the electron pairing and create a free electron you need only to affect the electron quantum spin properties.  Unlike in ionization where you need to add energy to the electron in order to free it.  Since electrons are spinnng they have magnetic dipole moments.  These dipole moments allow the electron to be effected by both the electric and magnetic fields.

You should buy a copy of Tom Valone's Homopolar Handbook. On the cover of that book is a photo of a large industrial homopolar dynamo, that is used in industry for billet heating and other things where you need huge currents but not much voltage. The way it works is that it is spun up to speed by hydraulic or other motive power, with peripheral brushes retracted off the disc. Then when it is at speed, with huge flywheel energy storage in the rotating disk, the peripheral brushes are slammed down onto the periphery of the disc and huge power is drawn off as very high currents for a few seconds as the rotation slows.

But in the text of the Handbook, you will find copies of the original research by Tom, and also the DePalma-Tewari documents, and a lot of other great information about homopolar dynamos. Many of the questions and problems posed in this thread are fully answered and explained in the Homopolar Handbook.

One of the more interesting things in the Handbook is the description of Tom's Master's thesis experiment, where he actually put an LED voltmeter _on the disk_  rotating with it. Can you guess his result?

Havnt bought the book yet.  But here is a review of his book, and the site it came from that seems to indulge in homopolar info.


" I have seen the "N" machine work. So have a lot of people. My only wish is that Bruce's dream for free energy for this planet does not die with him. If you are a tech type person please ignore the "naysayer" that debunks this info and experiment on your own.  Make your own conclusions by building your own "N" machine. I guarantee you won't be disappointed or be wasting your time. I also know Bruce Depalma will be smiling down on you...                                                                             Mike Galloway"
