The Searl Effect Generator (SEG) technology, as applied to the commercial market, had been previously developed to the point where a few prototype SEG generators were made, and used for electricity generation and motion. Commercial interest at that time focused on the SEG’s transport potential and, under commercial pressure to deliver a fully functional system, the original generators were used and lost in a series of vehicular propulsion experiments and demonstrations. Funding was insufficient to continue with the manufacture of the required larger-scale pressurized cabin machines --- resulting in the termination of the project at that time.

Although all the operating principles, precise proportions and weights of the required materials are known for three of the four required operating materials, the precise data of the original magnetic layer is uncertain. The objective of the current R&D programme s to re-establish the original magnetic layer using modern and more efficient materials.

Originally, the layered materials were constructed and magnetized by the now-defunct Midlands Electricity board under the direction of John Searl.

Modern magnetic materials have advanced considerably, and old ones discontinued, so a series of tests need to be conducted to establish the optimum materials and processes, These tests need to comply with the working criteria required and must lead to a cost-effective manufacturing process.

In recent times SISRC has been re-establishing the original research. Due to the very limited funding that has been available, only a partially functioning demonstration prototype of the SEG principles has been possible. This prototype consists of the innermost of the three composite tings required and several rollers…

Technical Description

Physically the Searl Effect Generator (SEG) consists of three concentric rings each made of a composite of four different materials which are also concentrically attached to each other. The three rings are fixed to rotate around them, are rollers --- typically 10 on the first ring, 25 on the next, and 35 on the outer ring. Surrounding the rollers on the outer ring are coils which are connected in various configurations to supply either AC or DC current at a variety of voltages. Multiple magnetic poles are imprinted on the rings and rollers to form frictionless magnetic bearings. These also arrange the static charge into opposing charge clusters which cause the rollers to rotate around the circumference of the ring (as shown in Figure 2)


Some expressions currently in use to describe the source of the energy for the SEG are the Space Fabric, Quantum Energy Field of Space, or Zero Point Energy. This is an unlimited and constant source of energy which can be made to flow when the correctly proportioned masses concerned are stimulated by the correct frequencies creating an ‘open system’.

The idea of utilizing this source of energy is currently the subject o various devices and experiments such as the ‘Lamb Shift’, ‘Casimir Effect’, and the work of the Russian Nobel Prize winner Ilya Prigogine. However, these devices and experiments tend only to prove the existence of energy and not a method to create a coherent, ordered flow to produce useful power.

In contrast, John Searl has discovered that, in order to create a steady and stable flow, all the masses of the device (and the stimulating frequencies) must conform to precise values determined mathematically by the ‘Law of the Squares’. A machine constructed to these principles produces a stable and useful power output.

Definition of a Surface-Operating SEG

A linear motor operating on a magnetic bearing with the characteristics of an auto-transformer. The SEG is defined as a device, which is constructed from 2,124 component parts, which make up 3 plates and 66 roller sets. 12 of the 2,124 components create the 3 plates, which act as reaction components. 2,112 components are employed to create 66 roller sets, which act as active components. Each roller set consists of 8 segments constructed from 32 components. Each segment cannot be less than 34 grams in weight, as the law of squares defines that value as the lowest value suitable for the reasonable generation of electricity. Therefore the smallest roller set must weigh 272 grams, making a grand total of 2,244 grams per roller set for the smallest surface-bound SEG.

Tolerance should be about 0.05 gram per roller set. The larger the error the greater is the loss of power within the unit. Therefore the total tolerance for the smallest SEG roller set must not be greater than 3.30 grams --- above this factor the SEG will not function. For the best results, the tolerance across the total 66 roller sets should not exceed 0.05 grams!

The SEG is a step-up rotary transformer. In fact it’s a ‘three rotary transformers’ operational system, within a unit. The inner transformer output is fed in to the input of the second plate which increases the output of the second unit, thereby increasing its final output to a very high voltage. Therefore the SEG is just a prime mover for the production of clean electrical energy. The output windings must be designed to step down this output to 240 volts at 15 Kwatts…

When the SEG rollers are brought into close proximity to the SEG Ring, te Searl Effect resonant magnetic field causes negative ions and electrons to be drawn into and accelerated through the machine. This process is assisted by the highly electron-attracting rare earth metal Neodymium.

The unique mechanical and material arrangement of the SEG pulses the neodymium to continually release and replace the surplus electrons to provide electrical or mechanical power, or both.


Prior to the production of complete 15 KW SEGs, a minimum of two demonstration Ring and Roller prototypes are to be produced.

The ‘Ring’ is typical of the innermost of the three rings required to make a complete SEG. The 69-roller sets in a complete 3-ring SEG are identical. Six roller sets will be made for the prototype inner rings so that the Searl Effect can be demonstrated.

The production of a self-running Ring and Roller prototype will establish the precise sequence and parameters of electrical, magnetizing and material processes required for the SEG and will demonstrate electrical power generation. An operating single inner ring with 1-8 rollers will also determine if a particular material will function correctly and at what level of power output…

"The Searl Effect Generator (SEG) is a magnetic diode, and what one may consider one of the original "Free Energy" Devices. The inventor of the technology is Professor John Robert Roy Searl of England. The SEG in essence is a composite ring made of an electron reservoir (a rare earth like Neodymium), a magnetized accelerator stage (Iron or Nickel), an electron flow regulator stage (Nylon 66 or Teflon), and finally, a paramagnetic layer (Aluminium or Copper). The design of the SEG is both beautifully simple and infuriatingly complex at the same time..."

"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.

"There are only ten rollers in the picture for safety reasons, as in a full set, the rollers will accelerate to 250km/h around the plate! This incredible feat is due to the instability of having an AC sine imprint on the plate and a cosine print on the rollers - instability created as the fields conflict causes the rollers to orbit the plate. They are held down by the magnetic field and thrown out by the centrifugal forces, so the rollers do not actually touch the plate when in motion. Thus, friction is virtually non-existent, and the high electrostatic charge accumulated by the SEG soon ionises all the nearby air and pushes it totally away from the SEG, enveloping it in an intense vacuum. High voltage flashover thus becomes impossible, and the potentials created by the generator can reach monstrous levels.

"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.
