DC separately excited motor commutation circuit

DC separately excited motor commutation circuit
Therotation direction of the DC motor is determined by the direction of current in the field and windings, the field direction of the magnetic field is determined by the direction of excitation windingcurrent. In the diagram (a), switching switch SA can change the positive and negative electrode connection of excitation coil (winding) L, while the polarity of the power keeps constant, it can change the rotation direction of the motor. In the diagram (b), it can use SA to change the polarity of power's two ends, and the polarity of the magnetic coil keeps constant, and it can also achieve reversible steering. If the polarity of the excitation coil and the power is changed at the same time, the direction of generated magnetic field will not change, so the direction of rotation will maintain.   (View)

ENERGY RECYCLING CIRCUIT
so what happens when you flip a switch? When you try to stop the flow of current in 'zero' time its equivalent to trying to stop a freight train instantaneously. you get a huge voltage buildup dv/dt = X/0=infinity This is one example of the use of a relativistic property of electricity. We may not be able to stop freighttrains instantaneously, but we can come close with electron trains.   (View)

Free Energy Schematic
The basic concept as I understand it, is a high frequency high voltage low current rectified and then used to charge a bank of high value capacitors and then to discharge them in pulse mode for brief period of time, nano seconds in fact by, means of a high speed electronic switching circuit or mechanical device and a rectification method that will only allow the high voltage charge to flow in one direction.   (View)

Bedini SG Energiser
John Bedini has been working in what is sometimes known as the free energy field for 35 years now. He would be amongst the first to correct this description as he would describe himself as involved with Free Radiant Energy which is not the same thing i.e. he is harnessing a form of energy little understood by the most of us.   (View)

Swiss ML Testakica
The Unit is started by hand by revolving the two disks in opposite directions and continues to move without further input. This device has only two moving parts namely the bearing races at the centre of the disk. The disk are made of clear plastic upon which are placed flat a series of fifty blade type steel or aluminium sections equally spaced around the middle sections of each disk. The speed of the revolving disks is about 50 to 60 rpm limited to this by magnetic impulses from the magnetic section on the rim.   (View)

Tesla's Energy Reciever
Tesla's free-energy receiver was patented in 1901 as An Apparatus for the Utilization of Radiant Energy. The patent refers to the Sun, as well as other sources of radiant energy, like cosmic rays. That the device works at night is explained in terms of the night-time availability of cosmic rays. Tesla also refers to the ground as a vast reservoir of negative electricity. .   (View)

Bedini Circuit

Bedini Circuit
The power is all in the timed switching process. There are two main principles I use of switching the radiant energy the John Bedini way. First, the SG/SSG, Icehouse unidirectional circuit or John Bedini Monopole with the School Girl Circuit (SG) Mechanical-Oscillator-Energizer and second, the John Bedini/Ron Cole switching oscillator circuit. Since my SSG4a/SG4a is a John Bedini/Ron Cole switching oscillator circuit, I should have called it BC4a meaning Bedini/Cole4a. (just to get the facts straight :) The main difference is the transistor arrangement of the first, usually in parallel, meaning for every wire a transistor/multiplying the J. Bedini circuit on the same heat-sink, which is used mainly for charging batteries and driving the rotor.   (View)

Free heater circuit by Rosemary Ainslie
Rosemary's original test circuit is shown in the article she tried to have published in a refereed scientific journal, but the submission was always rejected. In the last 5 months, I have had extensive email correspondence, and numerous telephone conversations with Rosemary, who lives in South Africa. After studying her work, I was absolutely thrilled with her discovery of the super-efficient heating effect. In mid-February of this year, I proposed to her an idealized schematic of her DC resonance circuit to produce the effects she had discovered.   (View)

Hans Coler Passive Circuit
He called this device the Stromerzeuger and for a few watts from a dry battery it provided 6 kW continuously. He was refused development support because it was a perpetual motion machine. Hans also invented a passive device which he called the Magnetstromapparat. His unit required very careful and slow adjustment to get it operating but when it started it continued on test in a locked room for three months of continuous operation.   (View)

Utilisation of Radiant Energy

Utilisation of Radiant Energy
This was filed on 21 March 1901 and granted on 5 November 1901. It was entitled: 'Apparatus for the Utilisation of Radiant Energy'. By installing two metal plates, one high above the ground and the other at ground level, with wires connecting the plates to separate electrodes of a capacitor, it was stated that the capacitor became charged to a very high potential, the energy input being that radiated to Earth from outer space. This may well have motivated the efforts of T. Henry Moray but, so far as this Applicant's invention is concerned, no such input from overhead components is necessary as a quite different energy source is at work, namely the zero-point vacuum energy activity of our quantum.   (View)

Electret Circuit

Electret Circuit
Arcing completes a circuit -- closes a system -- between two voltage potentials. When arcing occurs, two oppositely charged static voltage potentials can cancel each other out. The arcing problems that occur are usually between two electrically isolated voltage potentials pressures necessary to hold a charge and they are part of the same circuit -- completes a closed system.   (View)

Solid State Free energy Circuit
It's very simple actually. The idea is that we use what we have learned from the capacitor tests to create a circuit that uses the capacitors to run the load and then by discharging the 1/2 full capacitor into a DC-DC converter we can recharge the initial cap and start again. And have some energy left over.   (View)
