Motionless Electrical Generator system

The Motionless Electromagnetic Generator (MEG) is an electromagnetic generator without moving parts which includes a permanent magnet and a magnetic core including first and second magnetic paths. The MEG is alternatively pulsed to provide induced output current pulses. The United States patent office granted U.S. Patent 6362718 (G.patent; PDF) to the four inventors: Stephen L. Patrick, Thomas E. Bearden, James C. Hayes, and Kenneth D. Moore.

Alternately driven input 'choking' coils controls the magnetic paths.

According to some skeptics and other investigators, the MEG appears to be a special type of transfomer with a permanent magnet in its main flux path. Within the MEG, a set of input coils and a set of output coils extend around portions of the transformer-type magnetic core. A pair of input and output coil are on the right and left of the transformer frame. A permanent magnet is positioned in middle of the magnetic core. A permanent magnet furnishes magnetic flux lines moving from the north pole outward into the core material, resulting in a right and a left magnetic path. These paths extend externally between the north and south magnetic poles. A driving electrical current through each of the input coils (acting as a type of choke coil) reduces a level of magnetic flux from the permanent magnet within the magnet path around which the input coil extends. This distorts the hysterisis curve enough to cause flux of the core and generates voltage spikes on the output coils.

The MEG's magnetic core is compose of a magnetic alloy (of crystalline grains (or crystallite) of a few nanometers). These are used because of the material's rapid switching of magnetic flux charateristics. Each crystallite is a single-domain particle in magnetic terms. One of the magnetic materials prefered is the alloy of cobalt-niobium-boron, this alloy has a near-zero magnetostriction and relatively strong magnetization. This alloy also has a a relatively high mechanical strength and corrosion resistance. Other magnetic materials acceptable to be used can be iron-rich amorphous and nanocrystalline alloys. These materials exhibit a greater magnetization than the cobalt based alloys. An example of this alloy material would be iron-boron-silicon-niobium-copper. Though the permeability of this alloy is limited by their relatively large levels of magnetostriction, the formation of a nanocrystalline material dramatically reduces this level of magnetostriction and favors easy magnetization[1]

Initially, a sensing and switching circuit connects the switching and control circuit to an external power source. External powers sources can include, but are not limited to, a battery. The switching and control circuit is connected to an oscillator driver that is the clock input of a flip-flop circuit. The altenate outputs (Q and Q') of the flip-flop are connected through independent driver circuit, such circuit can include a darlington pair or a one-shot circuit (such as the one describe U.S. Patent 5268594 (G.patent; PDF)), to operate the FETS. The FETS alternately drive the input 'choking' coils. After being started, the sensing and switching circuit detects if there is a predetermined level of voltage available from a regulator circuit. Once this condition is met, the power input to the switching and control circuit is switched from the external power source to the output of regulator circuit. After this switching event, the electromagnetic generator operates without an application of external power.[2]

[Don't] confuse COP with efficiency, [...] they are two quite different things. [... The] coefficient of performance (COP) of a motor or system may be defined as (total useful output) divided by (energy input by the operator only). [... This] system has an efficiency of 50% but a COP 5.0.

— Tom Bearden

It is notable that during operation of the MEG the input coils are never driven to the point that the core material becomes saturated. If the core material is saturated, subsequent increases in input current that do occur has no corresponding effect in the magnetic flux and input power is wasted. In the the MEG, the switching of current flow within the input coils does not need to be sufficient to stop the flow of flux in one of the magnetic paths while promoting the flow of magnetic flux in the other magnetic path. The electromagnetic generator works by changing the flux pattern; it does not need to be completely switched from one side to another. [3]

Fe-based Nanocrystalline Magnetic Core :
Characteristics:

Nanocrystalline alloy has similar features of high
initial permeability and temperature stability,
less gravity and packing factor than that of
Permalloy. Under the same conditions of core size
and performance, it is lighter ( about 1/3 lighter)
and cheaper than that of Permalloy.

High saturation magnetic induction (1.25T), high
permeability, high inductance (ten times higher than
that of ferrite), low loss, small volume, light in
weight, high electric interference resistance, good
frequency performance and high temperature stability.

In an alternative embodiment of an electromagnetic generator, the magnetic core includes annular spaced-apart plates, with posts and permanent magnets extending in an alternating fashion between the plates. An output coil extends around each of these posts. Input coils extending around portions of the plates are pulsed to cause the induction of current within the output coils.

History

On March 26 2002, Tom Bearden announced the arrival of the MEG technology (Motionless Electrical Generator). This device was supposed to be in mass production by 2003, and promised unlimited energy from the vacuum, to answer mankind's power needs. Promoted through JLNlabs[4], Cheniere.org[5] and an Egroup called "MEG Builders"[6], the device was even written up in Vol. 14., No. 1, 2001, Foundations of Physics Letters[7]. As of 2005, the MEG is still not in production, and Tom Bearden claims he needs about $11 million to develop it to a viable commercial form. [8] Tom also admits he presently has no working prototype, stating the 'last working demonstrator promptly destroyed'.[9]

Controversy

Mainstream physics does not contain any mechanism allowing for "over-unity" devices; but does not prohibit "free energy" available directly from the environment and which cannot be depleted (so it is available in effectively unlimited quantity). Tom Bearden justifies the operation of the MEG with a wide range of alternative theories, including the proposal that all electrical devices, from batteries to electromechanical generators, in reality operate on vacuum energy. According to some skeptics, the theory seems to offer no concrete testable predictions though. A point within the framework from Bearden rests on the allegation that during the reformulation of the James Clerk Maxwell's orginal theory (of quaternions) by Oliver Heaviside and Josiah Gibbs into vector notation a key element was lost in the original theory. Also according to skeptics, the voltage spikes can be mistaken for an over-unity phenomena. The claimed suppression of various aspects of the MEG device and the theory behind it are examples of free energy suppression conspiracy theory.
