I am new to this forum so excuse me if this is repetitous.  I am an electric motor rebuilder and have seen alot of rotating electrical equipment. I believe that the unit is a torroidal permanent magnet wrapped with a winding.  Running within the circumference of the magnetic ring is a raceway ( hollow ring). Probably fabricated from non- magnetic tubing.  A ferrous ball is placed within the raceway.  The ball when accelerated around the tubing disrupts the magnetic field created by the permanent magnets.  The changing magnetic field induces current into the winding looped around the magnet. The interior part of the winding coils adjacent the tube create a magnetic field shift to keep the ball rolling. ( I have done this many times inside an electric motor stator to test windings without installing the rotor) The "trick question is where does the power come from?  The power is a fossil fuel. It was an electrical storm millions/billions of years ago that sent giga watts of electricity through a metal.  The liquified metal molecules reacted to the magnetic field generated by the "lightning bolt" then crystalized with all the ducks in a row.  The magnets in this machine will loose their field strength just like a battery discharges.
The magnets will have to be replaced and the windings rewound.  This machine is bascially one hellofabattery.  Step aside OPEC we're going to mine some magnatite instead.

   Sorry I'm a newbie and just got through doing more research on this machine.
My understanding now is that by pulsing the control coils wound around the ring a radiant electrical field is established at sequential positions along the ring.  This accelerates the conductor electrons.  Magnetic influences of the collector currents are parallel to the control coils so that they don't  slow down the control coil firings.  Basically a tuned wave emitter and round antennae. The device is so devised to accelerate the conductor electrons  faster and faster with minimal magnetic reaction  yet inside a conductor.  So at this point it is a converter from vhf to @ 500hz.  Where does the excess power come from?  The coils still need current to kick.  There are all sorts of losses from this device. Heat in the electronics, ir losses in the emitter and collector coils etc.  I believe that the unit creates a standing magnetic field free of induced magnetic field losses.  This magnetic field  channels  radio wave emissions  towards the collector ring.  Unfortunately it runs into the kicker coils and creates heat.  The magnetic field isn't perfect at vectoring the radio energy into the ring either and creates eddy current losses.  Hence all the heating.  Something like the old school am radio crystal receivers that you stuck in your ear and collected enough energy from the aether to push your eardrum to hear early 60's am radio stations.
