Cape Town, South Africa: Rosemary Ainslie began to question the established physical model in 1999. Combining curiosity with symmetry, patterns and applied principals of correspondence she developed a revision of the theory that complements it. Her model is able to reconcile the mass volume ratio of the proton to the electron and it suggests that all particles are constructed from varying numerical composites of a basic magnetic dipolar tachyon (named a "zipon").

She has been able to experimentally prove her concepts related to the electromagnetic interaction by inducing more energy from a circuit than is available from the supply. This resulting COP>1 suggests that there must be an alternate energy supply to the source and that the excess energy must, therefore, be from the circuit material itself. Her first experimental device as published in Quantum Magazine in 2002 achieved COP>17, and the simple circuit has since been replicated several times internationally. Her latest results point to an infinite co-efficient of performance.

02 May 2011: Ran heating element for 3 hours in air at 140'C (16'C ambient temp). Placed in 0.7 litres of water and heated water to 80'C, taking 60min to stabilise. Then raised frequency and over 6 min, water temp raised to 104'C (boiling) and battery voltage climbed and stabilised. See OverUnity thread.

A public demonstration took place on 12 March 2011. See video below. Latest reported results available here.

How it works

The circuit that is widely referred to as the Rosemary Ainslie circuit is actually a very simple variation on a square-wave generator and MOSFET switching circuit. The circuit here is designed to route energy back through the battery supply to ensure that it recharges the supply thereby conserving the charge of the batteries. The square-wave can be generated by a regular 555 timer circuit running in astable mode, or by a functions generator.


Rosemary explains:

When currents flow, when a path is forged through electric circuitry, they also induce a corresponding imbalance in the inductive components of that circuit. This is widely known. It is seen as "stored' energy. But the difference to convention and this model is subtle. This stored energy establishes an imbalance in the circuit material in that resistor or that element. Being imbalanced these fields also require an established state of balance. And given a chance to re-establish this balance, a chance to reduce this experienced and measurable potential difference, they in turn induce a second flow of current, in anti-phase to the first flow of current. So, provided that there is a path available in the circuit, it too can return its extruded fields back to it's own supply source being the resistor or the element itself. In other words there are two sources of energy in every one cycle of current flow through a closed circuit. The one is induced from the supply source, the other is induced from the resistor in series with that supply. Both have independent supply or energy sources and both are able to reduce their potential difference provided that some circuit path is made available to do this.

The availability of the path is in the circuit design itself. Here the source battery induces the first current path cycle, clockwise. Then that flow is interrupted by opening the switch and "taking away' the required closed path. But simultaneously there is a new path opened for the second cycle where the resistor transfers its energy onto a second path - anticlockwise. At fast frequencies, the two cycles are able to resonate against each other, like a swing that is first pushed in one direction and then in the other. And the net result is that the energy that is applied from the source is then returned to the source. The energy that is applied from the circuit is returned to the circuit. But in both cases that energy is simply strings of zipons that are trying to get back to their respective sources in order to diminish their experienced imbalance or their measured potential differences. So under these special circuit conditions there is not only a conservation of energy, being the zipons themselves which return to their respective sources, but there is also a conservation of charge in the supply which is then continually recharged during the second cycle of the switched circuit.

But what then explains the "heat" that is measured to be dissipated at the source? Here, again in line with observation but possibly not in line with classical thought, it is proposed that the zipons that are not extruded from the material of the circuit components, remain in the material, in the inductive wire itself. But the essential symmetry of their fields has been broken through the extrusion of some of its fields. This break results in a state of chaos that excites these fields into a cascade of zipons that re-congregate within that material in their attempt to regain that state of balance.

It is further proposed that the size of the zipons relates to its velocity. In a field they are cold and fast and small and entirely undetectable. But break those symmetries, and in a precise and inverse proportionate ratio the zipons become hot and slow and manifest. This, in turn results in some of those zipons decaying into photons and then radiating away from the resistive material itself. This results in the systematic degradation of the bound state of the resistor, which is seen as material fatigue.

NOTE: Despite the rather complex description above, the theory is easily grasped once visualised correctly - better diagrams and perhaps an animated video to follow. - Evan

More on the physics

Stable composites are required in certain fixed values of 2 for the photon, 3 for the electron and 9 for the proton. Other combinations are not stable and these are the virtual particles that then decay into the field. The field itself, is proposed to be structured from strings of these magnetic dipoles. The fields are sub-divisible into discrete strings of 6 magnetic dipoles that are numerically required to sustain a fundamental field condition. It is tentatively proposed that this basic parcel may relate to Planks Constant. It is essentially a classical model that proposes that all energy is from these particles in the various forms of their field condition. One dimensional fields are responsible for the electromagnetic force. They are extraneous to atoms and serve to bind them into molecules or to bind atoms together into three dimensional amalgams. Two dimensional fields are responsible for the strong nuclear force and are proposed to be located in the atomic energy levels. Three dimensional fields resolve themselves into a toroidal shape and, on both a small and large scale, are responsible for the gravitational force. the proposal is that in the field condition these particles are largely undetectable as they exceed light speed and are, therefore, invisible to light itself. It is therefore also proposed that this is the Dark Energy that has been uncovered by astrophysicists in the work done at Caltech by Ellis et al.






The system has shown operation in two modes: a) high-efficiency, high-heat production and b) unlimited efficiency with battery recharge and low-heat production.

Both modes provide sufficient heat for making hot water, thus units for individual homes would operate to create heated water whilst powering themselves and keeping a battery charged. A charged battery would power lighting, television and other low-current appliances. In the case of mode A, a small heat-to-electricity conversion system such as a peltier-effect module or Stirling engine could create enough power to recharge the battery power source.

The system consists of simple circuitry, lead-acid batteries and a standard heating element. Costs for a basic self-sustaining unit running a small house would be estimated (roughly) at less than R10,000 / $1500.

The technology has only been developed to proof of concept. It requires considerable research to take this to full application. What is critically required is the development of robust transistors that can manage the high level of energy for household application purposes. But the experimental results certainly indicate that this is feasible.

Independent testing

The companies listed below approved the inclusion of their name in publication of results, and, together with the authors of the article recommend a wider forum for systematic and statistical consideration of the experiment and its results:

The Cape Hope Metrology Laboratory confirmed that the test equipment had been calibrated at Tallumant’s Metrology Laboratory (facility no longer exists).

Spescom as distributors of Fluke instruments who attended demonstrations.

ABB Electric Systems Technology Institute in North Carolina who conducted independent tests. Here tests were confined to the evaluation of instantaneous power delivered simultaneously by the battery supply source and dissipated in the load. Measurements were enabled through the use of four channel oscilloscopes.

Johnathan Green of BP (SA) who applied tests to measure the effect of the energy gains on battery duration.

12 SASOL representatives who offered a bursary award to UCT to encourage further research. Unfortunately the offer was declined by UCT.

A patent application only (not a patent) was pursued in the early days only to garner sufficient attention for the device that it may be developed further - strictly NOT for control over the technology. Rosemary wishes the technology to be freely available to all, open-sourced.

(WO/1999/038247) HARNESSING A BACK EMF WIPO International patent

Abstract: A method of achieving high efficiency of energy usage includes passing current through an inductor, causing the current to be repeatedly interrupted, thereby generating a back emf in the inductor and thereafter harnessing the back emf so generated to supply energy to an energy receiving or processing device. The frequency of interruptions should be 40 Hz or more and is achievable by applying rectifying means to the current. The invention extends to apparatus for harnessing such back-emf and energy generating means comprising an inductor and current interruption means connectable to an energy receiving device.

Rosemary Ainslie Heater Circuit Replication by Aaron Self charges the front battery ABOVE the resting voltage before the test. 12+ hours later, the circuit is STILL running on the RECOVERED spikes. The circuit is supposed to dissipate EVERYTHING that leaves the battery but this is a bogus belief not based on fact or science. AFTER everything is "supposed" to be dissipated, a cap or battery can be charged just fine with the recovered spikes that amount to more than what the "experts" claim.YouTube link (19 July 2009)

Rosemary Ainslie experiment corroborates Quantum Ring Theory

From: Wladimir Guginski

To: Rosemary Ainslie

Subject: space filed by dipolar tachyon ZIPON?

Dear Dr. Rosemary Ainslie

Your hyphotesis of a space filed by zipons is agree to the structure of aether proposed in my book Quantum Ring Theory (QRT):

In QRT it is proposed that the aether is constituted by elementary particles:

Electric particles: e(+) , e(-)

Magnetic particles: m(+) , m(-)

Particles that promote magnetic permeability: p(+) , p(-)

Attractive gravitational particles: g(+) , g(-)

Repulsive gravitational particles: G(+) , G(-)

QRT proposes a new hydrogen modelof atom which works with such model of aether.

Also a new nuclear model is proposed, where a central 2He4 produces a current of "zipons" which form Dirac strings within the nuclei.

The Dirac strings produced by the central 2He4 capture protons, neutrons, and deuterium nucleons, and they form the structure of the nuclei.

Dirac strings existence was confirmed by an experiment in 2009:

Such new nuclear model is able to explain several phenomena not explained by current Nuclar Physics.
