Gyroscopes Overview Gyroscopes are a simple toy to many, yet they are poorly understood. This paper derives the mathematics of gyroscopes. Gyroscope concepts A gyroscope has three axes. First, a spin axis, which defines the gyroscope strength or moment. Let us call the other two the primary axis and the secondary axis. These three axis are orthogonal to each other. The spin axis rotates around the vertical line. The primary axis rotates the whole gyroscope in the plane of the page, and the secondary axis rotates the gyroscope up-and-over into the page. The spin axis is the source of the gyroscopic effect. The primary axis is conceptually the input or driving axis, and the secondary the output. Then if the gyroscope is spun on its spin axis, and a torque is applied to the primary axis, the secondary axis will precess. The primary axis appears infinitely stiff to the applied torque and does not give under it. This is the generally recognised characteristic of gyroscopic behaviour. It is important not to confuse the concepts of angular momentum and gyroscopic moment. When a mass ‘m’ moves in a straight line at velocity ‘v’ it exhibits linear momentum (m.v ). It is trivial to predict that if it is constrained to travel in a radius ‘r’ it will produce an angular momentum (m.v.r). However with the angular momentum an effect that could not have been predicted turns up - gyroscopic behaviour. The fact that in the larger world the two effects occur together and in simple proportion to each other does not mean that this is always the case - gyroscopic behaviour occurs without angular momentum in electron behaviour, even though the terms ‘spin’ and ‘spin angular momentum’ are still used for historical reasons, even though there is no direct evidence that the electron’s mass or charge spins on its own axis. It may simply be that rotating an object exposes the gyroscopic moments of the elementary particles that make it up, possibly through the asymmetric relativistic effects created by the centripetal acceleration; some major experimental work is required in this area. Angular momentum has the form “kilogram-meters2 per second”. Gyroscopic moment has the form “Newton-meters per Hertz”, or torque required to produce a precession rate of one Hertz. For those familiar with dimensional analysis, both have the dimensions ‘L2M/T’, which means only that they are related by a simple scalar number. However (as far as the author has been able to determine) the actual value has never been researched; it may be unity, it may not. Whatever the case, from here on I will ignore angular momentum and consider only the gyroscopic moment, regardless of how it is generated. Basic gyroscope equations The strength of a gyroscopic effect is termed the gyroscopic moment. I use the symbol ‘G’, in units “Newton-meters/Hertz”. A higher moment requires more torque to precess at the same frequency, or for the same torque precesses at a lower rate Where a gyroscope receives torque on the primary axis and precession on the secondary, no work is being done. The torque ‘TP’ on the primary axis has no precession associated with it, while the precession rate ‘vS’ on the secondary axis is... vS = T P / G ...and has no torque associated with it. Since the rate of doing work on each axis is the torque times the precession on that axis, it follows that in this simple case no energy is involved. Gyroscopes do not differentiate between primary and secondary axes - this is a purely artificial definition of my own. A torque on the secondary axis creates precession on the primary axis. Simultaneous torque on both axis will result in simultaneous precession. In this case each axes will have both torque (creating precession on the other axis) and precession (created by torque on the other axis). Then the rate of doing work ‘PP’ on the primary axis is... PP = TP.vP / G ...and on the secondary... PS = TS.vS / G Now by applying the conservation of energy... PP = - PS i.e. the work done on one axis must appear on the other. So far I have dealt purely with behaviour, but to go further we need to look at why it behaves this way - what mechanism is at work? Let us go through the basic operation where torque on one axis creates precession on the other (those familiar with electric motor theory will be familiar with the following ideas). First apply a forcing torque to the primary axis; at this stage in the argument imagine that the primary axis presents no stiffness against the forcing torque. The secondary axis would precess at an infinite frequency, but for a limiting mechanism that comes into play; just as torque creates precession, so precession creates torque. So as the secondary axis precesses it creates a reverse torque TPF on the primary axis... TPF = -vS.G The precession rate always runs at that point where TPF is exactly equal and opposite to TP. At this point... TPF = -vS.G = - ( TP / G ).G = - TP The reverse torque generated by the precession exactly opposes the applied torque so that the net torque is zero. If it was more the work would be done by the gyroscope. If it was less the primary axis would give way under the applied torque and work would be done with no outlet for it. Both conditions violate conservation of energy principles. To sum up, the gyroscope precesses the right rate on the secondary axis to exactly oppose the applied torque on the primary axis. This leads directly to an aspect of gyroscopic behaviour that is seldom experienced in conventional gyroscopes, but is important in the behaviour of electrons:- If the secondary axis is locked against rotation and the primary axis is driven, no opposing torque will appear on the primary axis - it is free to rotate without hindrance. No work is transferred through the gyroscope - there is motion without torque on the primary axis. The secondary axis has no motion - it is locked - but instead experiences a torque TSF... TSF = vP.G This is the identical situation to basic gyroscope operation, but viewed from the other side. Instead of saying that torque on the primary axis leads to precession on the secondary we say that precession on the secondary axis leads to torque on the primary axis. It is exactly the same thing. Using the equations Now look at the special case of a gyroscope operating in an external linear field that serves to invert it through exactly 180 degrees. For example, when a tabletop gyroscope whose bottom pivot point is fixed starts pointing upwards, the linear vertical gravitational field of the Earth acts to invert it. Figure 2 The gyroscope mass ‘m’ acts through the centre of gravity of the gyroscope. The vertical force is... m.g.sin(a) ...where ‘g’ is the gravitational constant of 9.81 meters per second. The torque around the gyroscope pivot point ‘P’ - and hence around the centre of mass - is... TP = m.g.r.sin(a) ...where ‘r’ is the radius from the pivot point to the centre of mass. This creates an instantaneous precession FS that in Figure 2 will cause the gyroscope to precess out of the page at the top of the picture. The instantaneous rate of precession is... vS = m.g.r.sin(a) / G Now the reason for emphasising that this is the instantaneous rate, is that TP is not a simple torque under the external linear field. As the gyroscope precesses out of the page, the angle the field makes with the gyroscope rotates with the precession. The end result of this is to cause the gyroscope’s precession to be truncated into a circle whose circumference is normal to the field. The circumference of this circle is shortened to... r.sin(a) ...while the full precessional circumference would be simply ‘r’. This means that it takes the gyroscope less time to trace out the circular path, so the actual foreshortened precession rate is corrected to... vS = (m.g.r.sin(a) /G) / (r.sin(a) / r) = m.g.r / G = TPmax / G In other words the revised precession rate is constant. Now if you experiment with a table gyroscope you will find that it will slowly droop as it precesses, so that the free end - opposite the pivot point ‘P’ in Figure 2 - will tilt more and more towards the table surface. It may seem at first that it is simply falling under gravity, but if you examine the motion you will find that the gravitational energy used up is not being translated into kinetic energy since the rate of droop remains slow and controlled. So we need to find out where the energy is going to understand the behaviour. In fact it is simply precession! What is happening is this:- The torque produced by the gravitational field on the primary axis causes the precession on the secondary axis. However, the secondary axis has friction associated with its motion, and this creates a frictional torque on the secondary axis that in turn causes precession on the primary axis. Energy conservation tells us that torque times precession on one axis must equal the negative of torque times precession on the other, so that the sum of the two energy rates is zero. The work done by the gyroscope in going from the straight-up to the horizontal position may be found by integrating the torque over this rotation, when it will be found to be numerically equal to TP, but in joules of energy, rather than the TP Newton-meters of torque that creates the motion. So in the table gyroscope example, TP joules of energy will have been lost to friction on the secondary axis when the gyroscope has dropped from the straight-up to the 90-degree orientation on the primary axis. Full inversion from straight-up to straight-down involves 2.TP joules. This leads to an important relationship. For any gyroscope the precession on the secondary axis is... vS = T P / G ...and the work done in inverting the gyroscope from straight-up to straight-down in an external field is... E = 2.TP ...so the ratio of energy to frequency is... E / vS = 2.TP / (TP / G) = 2.G In other words, a given gyroscope moment G will always result in the same ratio of energy to frequency. Another example is an electron in an external magnetic field. The electron has a gyroscopic moment and a magnetic field. Now the tabletop gyroscope has frictional losses and operates in a linear external gravitational field that serves to invert it, while an electron has electromagnetic radiative losses and operates in a linear external magnetic field that serves to invert it. In the former case the external field acts on the mass, while in the latter case it acts on the magnetic field of the electron. However, the maths is identical, with the electron’s gyroscopic moment being h/2 (‘h’ being Plank’s constant)... E / v = 2.G = 2.(h/2) =h ...so as you can see Plank’s constant owes nothing to the electromagnetic world - it is a purely gyroscopic property. The concept that the electron spin is 1/2 is related to its gyroscopic moment being h/2. Although it is difficult to do for the table gyroscope, it is easy to reverse the process for an electron, to cause it to return from the straight-down (field alignment) position to the straight-up (field opposition) position. Just as a loss torque on the secondary axis causes the precession on the primary axis from straight-up to straight-down, so a gain or forcing torque on the secondary axis will cause precession on the primary axis back to the straight-up position. How this operates with the electron is beyond the scope of this paper, but it is possible to employ an electric motor integrated into the secondary axis of sophisticated gyroscopes to overcome and even reverse frictional losses. Gyration An interesting characteristic appears when you put a spring on the secondary axis. As you drive the primary axis the secondary axis will at first precess and the primary axis will be stiff, but as the spring winds up you will find the precession slow down and stop, and as a result the primary axis will give way more and more until it rotates freely. This behaviour is that of an inertial torque on the primary axis. Equally, if you put an inertial torque on the secondary axis the primary axis will behave like a spring torque. This behaviour, where inertial torque is converted into spring torque and vice-versa, is termed gyration. Compound gyroscopic action The foregoing discussion presupposes that the primary and secondary axes are massless, so that when they precess they have no gyroscopic moment. This is never actually true. As soon as the primary or secondary axis starts to precess its inherent mass creates a gyroscopic moment on that axis. When you take a spinning gyroscope and apply torque to the primary axis it causes the secondary axis to precess. This causes the secondary axis to develop a small gyroscopic moment of its own. This axis then acts as an alternative spin axis coupling torque on the primary axis to the original spin axis (acting here as an alternative secondary axis). Because this gyroscopic moment is normally very low, torque on the alternative primary axis generates very high precession rates on this alternative secondary axis. The resultant picture is inevitably difficult to visualise... The following table shows the relationship of the first alternative axes to the original ones in this particular example... Second Axis Original First Alternative Alternative 1 Spin Secondary /Primary Primary/ Secondary 2 Primary/ Secondary Primary/ Secondary Spin 3 Secondary /Primary Spin Secondary /Primary If we accept that there is no real difference between the primary and secondary axes there are just three gyros, each corresponding to one of the three possible spin axes. Comparing the original and the first alternative... Original: The high-rate spin on axis 1 generates a high gyroscopic moment so that torque on axis 2 generates a low-rate precession on axis 3. Alternative: The low-rate spin on axis 3 generates a low gyroscopic moment so that torque on axis 2 generates a high-rate precession on axis 1. Note that there is no fixed relationship between the spin rates for each viewpoint. In normal circumstances our viewpoint is locked to the spin axis with the highest gyroscopic moment, but this does not mean nothing else is going on. Let us use the notation where the suffix has two characters, the first being either ‘O’ for original or ‘A’ for first alternative from the above table, and the second being the axis number. Then for the specific case where the gyroscope mass is a sphere so that the angular inertia is the same on all axes, the gyroscopic moment is always directly proportional to the spin rate, regardless of the axes combination. Then... TO2 = vO3.GO1 TA2 = vO1.GO3 But for a sphere, where the inertial moment is the same for all axis, the gyroscopic moment is proportional to the spin rate, so... v01.GO3 = vO3.GO1 ...so that for stable precession/spin in this compound case... TO2 = TA2 That is, the torque supplied to the ‘A’ set must be matched by an identical torque applied to the ‘O’ set. Since this is the same axis you must supply double the expected torque as the sum of the two. If the rate of precession vO3 (= the spin rate sA3) is fixed by the frequency that the forcing torque rotates in the above image, then if TO2 is increased beyond TA2 the spin rate sO1 will increase, while if it is dropped below TA2 it will fall. Since the spin has angular momentum energy must be supplied in the former case to spin it up, while in the latter case energy will be released from the gyroscope as it spins down. In this manner it is possible to “pump up” the orginal spin axis rate by utilising an alternative gyroscopic moment that treats it as a secondary (precessing) axis. There is an extremely effective application of this on the market - the “Power Ball” wrist exerciser. Given the difficulty of visualising compound motion in three dimensions it may be worth getting hold of one if you are sufficiently interested. You can then store flywheel energy in a gyroscope’s original spin axis, charging and discharging that energy by means of an alternative spin axis. Suppose there are losses on axis 3 rotation so there is torque and precession (and hence work being done). The original gyro set maps the energy from O3 to O2, which therefore also has precession and torque. The precession on O2 couples to A2, and from there into A1, so that work lost on the spin axis A3 couples to work supplied on the spin axis O1. During these charge or discharge cycles the orginal spin axis can be seen turning end-over-end as the alternative spin axis A3 revolves. The clever thing about this approach - as opposed to simply tapping the original spin axis directly for its flywheel energy - is that the output frequency and torque can be held constant during the discharge without gearing even though the flywheel is slowing down. Removing the Gyroscopic Moment If the equations for angular momentum and gyroscopic moment are truly independent, can we separate angular moment from gyroscopic moment in a flywheel? The answer is “Yes” - simply ensure the mass travels in a circular path, but does not rotate. Imagine a flywheel which is simply a frame that carries two masses which are free to rotate independently on their own axles... Then add some gearing (not shown) that makes the two masses counter-rotate slowly in the opposite sense to the frame’s rotation. This is at a much lower rotation rate than the frame’s rotation, just enough to offset the small gyroscopic moment of the frame. With the right gearing the frame’s gyroscopic moment will be annulled by the masses’ counter-moment and you will have a flywheel with plenty of angular moment, but no gyroscopic moment. Many other arrangements are possible - two contra-rotating flywheels close to each other on the same axis will do the trick; the gyroscopic moments cancel out but the angular moments add. The application of such a device is to engines in high-performance machines. For example the engines in small aircraft have such a high gyroscopic moment that they can affect the handling of the aircraft, and longitudinally- mounted engines in racing cars can affect manoeuverability. Gyroscopic Propulsion Warning - Gyroscope propulsion is currently just speculative research and is not accepted by the scientfic community. These propulsion pages should be regarded separate from the rest of the site. What do these "Propulsion devices" do? The concept is to produce a gyroscope based device that can produce sufficient amounts of lift/force to be detectable and useful. In an extreme case this may mean that the machine could lift its own weight and hence is able to fly or just to push something along. However research is still in its early stages and I've yet to see one that can create any force under proper test conditions. The use of the term "Anti-Gravity Device" The use of the term "Anti-Gravity Device" is sometimes associated with this type of device. This is misleading and confusing in many ways and I don't believe the term should be used. It is highly unlikely that these type of devices effect gravity in any way. I believe the forces are independent of gravity and more related to the gyroscopic forces. From the evidence I’ve seen, if these devices really do produce force I believe energy is some how converting from rotational energy to a linear thrust. Then these 'machines' can be put to better use in space with a zero or micro gravity environment. Are these devices related to zero point energy? As far as I'm aware none. In fact great amounts of energy has to be put in to get any linear force out (if any). Uses for gyroscopic propulsion devices Gyroscopic propulsion would have a number of uses on land, sea, air and space. What uses the device can do depends on the amount of force produced and its efficiency to produce that force. It may turn out that they can only ever produce a force a fractional of the weight of the device e.g. a 10Kg device give 1% thurst = 100g thurst. The weight to thrust ratio will define whether the technology can be used on land, sea and in the air. However in space the devices come into there own and they would be useful even if they could only produce a small thurst compared to theier mass. Rockets are used almost exclusively as a means of propelling something in space and although inefficient, it is the best we have at present. Assuming gyroscopic propulsion does work it provides a means of getting from A to B in space without taking your fuel up too. The devices could simply be solar powered so the fuel won't run out. Of course the device still needs a way to get it into space in the first place. Sandy Kidd and Force Precessed Gyroscopes A simplified description of force precessed gyroscopes In the following set of diagrams red arrows are used to show the force applied to the structure. Provided the gyroscopes themselves are rotating in the correct direction (not shown on diagram) the gyroscopes will produce a counter-acting force known as precession, as shown in the diagram as two blue arrows. Normally this would produce a continuous torque as the whole device is revolving which would cancel it self out in the form of stress in the structure of the machine. However in Sandy's patent the gyroscopes are pushed in/out using cams resulting in the following motion (represented by the eight diagrams). As far as I can understand a number of up-ward pulses are produced due to the two gyroscopes (in this particular case, more can be used) exerting a force towards the centre of the structure (axle). This in effect is a vastly simplified version of what is going on. A number of independent tests have shown results for and against the machine. SIDE VIEW TOP VIEW Jacket photographs: front; Topham Picture Source/Carolyn Jones: back; Fotopress, Dundee Image: Copyright Grampian Television PLC While working in the Air Force, Dundee based engineer Sandy Kidd was one day taking a gyroscope out of an aircraft. Not realising that the gyroscope was still running, he came down the steps of the aircraft and turned at the base of the steps. At this point the gyroscope almost threw him across the floor. This stirred his interest in gyroscopes, Sandy spent many years and tens of thousands of pounds in his garden-shed/garage developing and working on gyroscopic devices. Trying to get a number of gyroscopes to react against one another to produce lift. In time he developed a device that he claimed could achieve this. Building other models using that principle and discussing his ideas with others, he came to conclusions of how it worked. Dundee University was interested in the invention and for a time worked with him, but long term could not supply the funds or enthusiasm that was needed. He tried obtaining funds to develop his invention in Scotland, but had to resort to looking for funds elsewhere. An Australia corporation BWM took the task on to develop a gyroscopic propulsion system but unfortunately the company went bust. British Aerospace has also been involved in the research with him but dropped the funding. A UK/European patent for his invention was applied for (I have a copy of the application). I did try to find a granted patent for Europe but without success. I ended up phoning the European patent office to find out if one was granted. I was told that it would have been, but it was withdrawn at the last moment (funding dropped). I did however find a granted US patent (5024112). The fees for the patent have stopped being paid for some years ago. Which means anyone is free to copy, sell etc his invention (At least in the US/Europe). Sandy is still working on various devices based around gyroscopes and hopefully we will be seeing more inventive designs from him in the near future. Image: Copyright Grampian Television PLC Dr Bill Ferrier of Dundee University talking about Sandy Kidd's machine in 1986: "..............There is no doubt that the machine does produce vertical lift. Several modifications were then made at my suggestions in order to disprove other possibilities of lift, particularly aerodynamic effects. I am fully satisfied that this device needs further research and development. I have expressed myself willing to help Mr Kidd whose engineering ability is beyond question, and for whom I now have the greatest respect. I am currently trying to interest the university in housing the development and also in finding 'enterprise' money to fund the next stage. I do not as yet understand why this device works. But it does work! The importance of this is probably obvious to the reader but, if it is not, let me just say that the technological possibilities of such a device are enormous. Its commercial exploitation must be worth millions." Professor Eric Laithwaite (14th June 1921 - 27th November 1997) Image: Copyright Grampian Television PLC Click here for more information about Eric's work Geoff Russell (Geoffrey C Russell) July 1999 I got in contact with Geoff Russell (Patent No.2,090,404). He tells me that the machine based upon his patent has changed quite a lot. Vast improvements have been made over the years and he now has a device that he says "weighing 22lb, which was able to consistently register weight loss or vertical lift pulses of 20lb, give or take the odd oz". He has very kindly given me diagrams and notes on one of the ways that he tests his devices "Notes on Fig 1 Vertical Lift Weighing Board Fig 1 is designed to detect and measure any vertical lift being generated by your machine. This is achieved essentially by providing a stable base on which to test your apparatus. While leaving the base and apps free to tilt vertically upward, in response to any vertical lift being generated. Fig 1 consists of a flat rigid wooden board approx. 1" Thick, the overall size of which should be determined by the size and weight of your own apparatus. The board has two L shape aluminium sections attached to its underside. With the first positioned at the central pivotal axis and the second positioned at one end of the board. A contact switch is attached to this aluminium section so that it operates, lighting an indicator lamp each time the board tilts upward loosing contact with the ground. A counter weight approx. the same weight as your apparatus is also required to vary the balance of the board. By varying the position of the board movement of the counter weight towards the central pivotal axis of the board, would mean that your apparatus would have to generate greater vertical lift to light the indicator lamp. Moving it away from the control axis has the reserve effect. To determine how much vertical lift your apparatus is generating, you must use a spring balance to measure how much upward force is required to raise your apparatus sufficiently to tilt the board upward, lighting the indicator lamp. The reading you get is the amount of vertical lift your apparatus is generating. You should make a position on the board at which your apparatus is placed for all tests, including the measurements you take before each test to determine how much weightless or vertical lift is required to light the indicator lamp... ...Geoff Russell July 1999" Geoff Wilson and the Wilson-Fourier Impulse Engine Website: http://www.sbbg.demon.co.uk/ Geoff Wilson is part of team working which have been experimenting with gyroscopic engines for some 20 years.

Poliakov Device and an action of Inertial force deviation propulsion system Outline Inertial force deviation propulsion system is the device to get the thrust of relativity theory effect . To get thrust we must drive the device at very high speed. We can convert electricity into thrust directly by using erectorical motors for driving device. Configuration This system consists of turn table and gyro. 1.Turn table The turn table ( blue part in diagram )turns with purple axis. 2.Gyro The gyro (green part in diagram )turns with light blue axis fixed in turn table. Four gyros are fixed in turn table in this diagram. We can chice the number of gyro as 2 or 3 and more if gyros are symmetry about the purple axis . The magnitude of the thrust is proportion to number of gyro. Action and effect If we give counterclockwise spin to the turn table, and give clockwise spin to gyros with high frequency. (relativity speed) We can get The thrust from each gyros. (red ↑) Why this phenomenon occur? It is why the rate of time on the gyros depend on position . It is just a relativity effect. We call this phenomenon inertial force deviation. We call the new propulsion system as inertial force deviation propulsion system. 29 April 1995 The Secret of the Force Machine by Bruce DePalma In the analysis of Free Energy machines it is shown that spatial distortion created to elicit electrical power extraction or anti-gravitational effects, results in the appearance of physical forces in the apparatus. The physical forces which appear represent the tangible counterpoise of the spatial distortion. Anti-gravitational Effects When a real mechanical object, a flywheel, is rotated, forces appear, the centripetal forces of rotation within the material of the flywheel. These forces are the counterpoise to the spatial distortion created by the centripetal acceleration applied to the mass elements of the rotating wheel. Although these forces are not available for explicit measurement, their presence is evidenced when the wheel is rotated at a high enough speed such that the forces exceed the tensile strength of the flywheel material and an explosion results. The interesting phenomenon is that no work is required to maintain these forces at arbitrarily high values. The gravitational field of the Earth is a spatial distortion occasioned by the presence of mass. The weight of an object is measured by a scale under a condition of constraint, i.e. no motion, and represents the degree of spatial distortion at the point of measurement. Objects in free fall are not acted on by Newtonian forces, consequently their rate of "fall" is subordinated to rate of influx of the gravitational flow. A hydro-electric power station extracts energy from the gravitational energy flow. Gravitational energy is a flow not a force which distinguishes it from Newtonian forces arising from the acceleration of masses. Reasoning by analogy with electrical Free Energy machines within which forces are manifested proportionally as a counterpoise to the degree of spatial distortion required to elicit a certain level of output electrical power, we can hypothesize that to paddle upstream in the gravitational flow a mechanical Free Energy machine would also manifest within itself such a force counterpoise. Thus to generalize we can say that in the class of machines known as Free Energy machines the mode of such apparatus, either in the mechanical or electrical form, is such that the principle of operation is expressible as an equivalence between the explicitly manifested mechanical force counterpoise and the power output of the machine whether it be mechanical, electrical, or other. The gravitational flow represents mechanical power, because power can only be extracted from a flow of power. If the mechanical power output of a machine exceeds the gravitational power flow in the region of its operation then a force will be developed in the direction opposite to the gravitational flow and an anti-gravitational effect will be demonstrated. Actually what is connoted as gravitational power flow and mechanical power output derived from Free Energy anti-gravitational apparatus is Time-Energy. This subject is discussed in other of my writings, reference (1). The archetypal gravitational engine or Free Energy machine is a combination of two counter-rotating gyroscopes with axles parallel and rotors co-planar. The original Force Machine was constructed in 1971, figure (1). The total weight of the apparatus was 276 lbs. The "active" mass at the rim of the flywheels was 10 lbs. The assembly was suspended from a spring scale and the gyroscopes driven counter-rotating at 7600 r.p.m. Under these conditions the support cylinder was driven at 4 r.p.s. to precess the gyros. A consistent set of experiments repeatably showed 4 - 6 lbs. of weight loss. Although thousands of pounds of force were developed, expressed as tension and compression in the walls of the support cylinder, none of this could appear as torque in the precessional axis due to the geometry of the machine. Precession more rapid than 4 r.p.s. caused fracture of the tool steel gyro support axles. It is easy to see how the machine design could be improved by mounting both gyros on the same axle and supporting the developed precessional forces by one rotor bearing directly on the other. Other mechanical improvements would greatly increase the achievable antigravitational effect. Figure (2). The important observation is that in a Free Energy anti-gravitational Force Machine, essentially no input mechanical power to the precessional axis is required in the manifestation of arbitrarily large forces in the walls of the gyro support cylinder. From the point of view of physics we can say there is an equivalence between the force explicitly developed in the walls of the machine and the mechanical, time-energy, power produced. Thus in this machine we have in operation a Force - Energy equivalence paradigm of great power. In contrast, the consumptive physics now in vogue can only offer a Work - Energy paradigm expressed in machines which are said to "convert" raw materials into energy. Electrical Force Machines The N-machine In the construction of an electrical machine analogous to the mechanical Force Machine use is made of the phenomenon of the Faraday disc. It is known that in electrical machines consisting of a conducting disc rotated proximate and co-axial to the magnetic pole of an axially suspended magnet, figure (3), no reaction torques are transmitted from the driven or driving disc to the magnet supplying the exciting field. Attachment of the conducting disc to the magnet itself and co-rotation of disc and magnet elicit an electrical potential between the center and outer edge of the conducting disc. Electrical power at a high degree of efficiency exceeding the electromechanical equivalent of work may be drawn from this apparatus, (N-machine). When the N-machine was originally disclosed to the public, ref. (2), (3), careful testing revealed output electrical power exceeding equivalent input mechanical power by 5 - 7.7:1. Theoretical considerations derived from experiments with the mechanical Force Machine would lead one to expect that power could be extracted from such a machine almost free, i.e. electrical power could be extracted without any drag being reflected on the source of driving energy. Many other experimenters attempted to "improve" on the original design. In most cases however while overall efficiency was greater than unity it rarely exceeded 2:1. What was forgotten was the withdrawal of electrical energy in itself created a spatial distortion which interfered with the action of the machine by creating drag. The high efficiency of the "Sunburst" prototype was due to partial compensation of field distortion created by current withdrawal. With reference to figure (4), the magnetic field created in the rotating current collecting disc was partially cancelled by current flow in the opposite direction in a fixed conducting plate, situated as close to the rotating disc as the thickness of the brush assembly would allow. Indicated schematically in the drawing. An improved machine would position a fixed compensation plate as close to the rotating disc as physically possible. Thus current withdrawal would cause the minimum distortion of the exciting magnetic field. In this case almost totally free power would be obtained. The double machine of figure (5) shows an almost ideal configuration where compensation for the spatial distortion of current withdrawal as well as doubling of voltage output is accomplished by contra-rotating magnetized rotors supported on a single shaft. There is a striking similarity between this construction of an N machine space power generator and the suggested twin counter-rotating gyroscopes mounted on a single shaft as an antigravitational mechanical space power generator. It is suggested that a mechanical space power generator is converted into an electrical space power generator simply by magnetization of the gyroscopic rotators. In terms of the Force - Energy paradigm the constrained repulsive force generated between the contra-rotating magnets upon the withdrawal of current represents a measure of the electrical power output of the machine. In the anti-gravitational space power machine the torques created in the precession of the counter-rotating gyroscopes, absorbed one upon the other are representative of the anti-gravitational effect. Force - Energy On the basis of the geometry of both the electrical and mechanical force machines there should be no drag or resistance to precession of the counterrotating gyroscopes or contra-rotation of the magnetic rotors. Force - Energy equivalence relates to the relationship of internally generated constrained forces and space power output. What we would call efficiency would relate to the work input to these machines, i.e. torque x angular velocity compared with the space power output. Space power is developed out of distortion of the normally isotropic space, the amount of distortion being represented by the reflected internally constrained forces explicitly developed in these machines. As yet there is no measure of space power expressed mechanically as an anti-gravitational effect. Electrically developed space power can be measured in watts. Consequently the efficiency of an electrical space power generator can be expressed as electrical watts output divided by the electrical equivalent of mechanical power required to rotate the magnets. On the basis of present understandings of electrical and mechanical forces, the geometries of both the mechanical and electrical space power machines allow of none of the internally constrained forces developed to appear in the drive axis. Consequently space power should be developed as totally free mechanical or electrical energy. Measurements on practical machines however do show drag to be present. Because one torque is neutralized by an equal and opposite mechanical torque or a force of electrical repulsion is constrained by an equal and opposite mechanical force does not mean that the space in which the neutralization occurs is returned to its original state of isotropicity. I have given a great deal of consideration to this situation. Defect of Forces In the conservative physics of the work-energy paradigm the thermodynamic law of Equi-partition of energy gives some insight of the energy coupling of orthogonal modes of mechanically interpreted systems. In the physics of energies elicited through spatial distortion of the cosmic primordial field a useful idea is the concept of Defect of Forces which can help us understand the properties of situations whose neutrality is achieved by the balancing of equal and opposing similarly derived forces. The idea is that when a force is manifested as a counterpoise to an experimentally created spatial distortion, i.e. the forces existing in the body of a rotating flywheel, mutually constrained precessional torques or the balancing of electromagnetic distortions by the superposition of equal and opposite vector fields; the manifested force is not perfect. A perfect force by definition possesses only magnitude and direction. A real force manifested as a counterpoise to a condition of spatial distortion has a magnitude, a direction, and something else. The something else would be a property of imperfection common to the universal manifestation of what we know as Reality. The philosophical treatment of the innate imperfection of Reality is beyond the scope of this paper. Suffice it to say, in a physical sense, the defect of forces is a real entity and is the property held in common by all manifested forces, and represents a possible mode of coupling between them. For example an explanation for the phenomena of inertia can be developed out of the coupling of atomic and nuclear forces to the balance of the mass in the Universe through the mechanism of defect of forces. The defect of forces exists, yet is unquantifiable except in terms of itself and has no known properties in terms of things that exist. Its existence is non-existence yet it is held in common with all things that exist. I posit that defect is connected and is responsible for the phenomenon of inertia. In terms of this paper I posit the drag which appears in the drive axis of orthogonal machines is a coupling of the force counterpoise of the created spatial distortion into the drive axis through the mechanism of connectivity of defect. Summary Force - Energy equivalence is a simple expression that in what I call orthogonal machines a force is manifested proportional to the degree of created spatial distortion. The primordial cosmic field is pure energy, consequently distorting it to obtain a polarization from which power is drawn can make available an arbitrarily large quantity of energy. The energy available is limited more by the mechanism of extraction than the cosmic field. The idea of efficiency applies to the particular configuration of mechanically realizable extraction apparatus. Force - Energy is a way of characterization of the degree of spatial distortion achievable with mechanical apparatus. Defect of forces is a concept to explain why free energy machines are not infinitely efficient. It is also proposed as a mechanism to explain the phenomena of inertia. The machines we construct are almost infinitely puny in comparison to the energy released from the cosmic field observed in the super-nova. The ideas of spatial distortion, Force - Energy equivalence, and defect of forces may open our eyes somewhat to the latent and omnipresent power and majesty of the universe. Addendum It is constructive to consider the interpretation of familiar phenomena from the viewpoint of Free Energy. Distortion of the cosmic energy field by the presence of mass evokes the gravitational flow of time energy. The measure of the created spatial distortion is the force counterpoise known as weight. Distortion of the primordial field by a rotating flywheel or gyroscope evokes the od field of inertial anisotropy. In this case the force counterpoise is not explicitly available but nonetheless exists centripetally expressed within the body of the rotating object. In the interpretation of stellar phenomena the could result in the liberation of heat. Denser temperature. The liberation of energy in stars their mass. As stars became more dense because gravitational flow into matter matter would increase in could result simply because of of gravitational accretion of mass more energy would be liberated. Under gravitational pressure matter itself might have various stages of collapse. The first stage of collapse could precipitate from the cosmic field energy sufficient to cause a Nova. A second state of collapse could precipitate a Super-Nova. A normal stable star would operate in a density range where matter would retain its identity in terms of the series of known elemental configurations. The collapsed matter stages of the nova or super-nova can only be hypothesized and probably would not be available for study under terrestrial conditions. The important observation is that the explosion of a star is analogous to the explosion of a flywheel when rotated at sufficient speed such that its internal cohesion is neutralized by a superabundance of time energy precipitated from the cosmic field. In this case the invocation is rotation. For stars the invocation is mass density and the perceived effect is the gravitational flow. What the rotating flywheel and the star have in common is that an explosion can occur when the internal energy exceeds the forces of material cohesion. A long and useful life results when the density of energy invoked from the cosmic field is less than that required for the disruption of the elemental materials from which they are constructed.
