The craft pictured here are Inverse Gravity Vehicles (IGVs), of which 41 prototypes were built, and one large version was constructed, the DEMO-1, in 1968. The smaller craft were the P series IGVs, approximately 11 feet in diameter and weighing a few tonnes. DEMO-1 was 21 feet in diameter and weighed 11 tonnes. You can see it flying here to the right.
Inside each of these IGVs there is a powerful 3-ring SEG which provides levity to the craft through a combination of magnetic, electrostatic and flywheel effects, many of which I freely admit are beyond my comprehension.
The iron element in the SEG "plate" (the big ring) is magnetized with a combined DC and AC magnetizing sequence which causes many poles to form all over the surface of the iron, in a wave like pattern corresponding to the AC frequency used. The iron element is then combined with the others (which are NOT involved in the magnetizing process) in a process called sintering - pushing them together under pressure. The same is done for the smaller magnets, or "rollers", except that each roller consists of eight stacked segments held together by the magnetic field. When you have twelve roller stacks and a correctly magnetized plate, and place the rollers on the plate as below, something truly amazing happens.
Unlike any other form of electrical technology, the presence of electron flow throught the generator actually cools it, reducing the resistance. This is due to free electrons being pulled out of the air and the resulting energy deficit causing the air to cool. As one places a greater and greater load on the SEG's induction coils (fitted so that the rollers pass through them to produce high-frequency AC), the rollers accelerate to accomodate the added energy drain, more power is pulled from the air, and the temperature lowers even further. A critical point is eventually reached. At 4 degrees Kelvin, the SEG superconducts and totally loses all electrical resistance. At this point, it levitates, completely enveloped in a perfect vacuum. Without control, it will accelerate up away from the Earth and disappear off into space, never to be seen again. To control it, a powerful radio frequency emitted nearby is required. If the same RF is transmitted as the AC frequency used to magnetise the rollers, they will completely stop. This acts as an ideal control gate, preventing the loss of costly generators.

This area will now house all the Searl-related pictures I can get my hands on. They say that a picture speaks a thousand words......
Above is a picture of a completed ring, with the iron ring-elements magnetically bonded to it. Note that the ring shells are not complete yet.
A picture of the "Glass SEG", with which the effect may be demonstrated with a simpler magnet setup. (Couldn't you just imagine this in the science museum?)
A picture of a 3-variant IGV shell. This one was taken quite recently I believe.
A picture of a ferrite SEG configured to produce high torque.
A picture of the construction of an IGV, probably one of the P-series, not DEMO-1
Another IGV construction scene. Note the 1960s car in the background
One more picture of IGV construction
