Mr. Sullys' forum thread at PhysOrg:
I'm going to try to stumble through an explanation.
Lets use figure 12 from the patent for discussion to avoid confusion:
From the Patent:
The multi-directional electric currents have the effect of accelerating processes that rely on interaction between a current and the medium that carries the current, and of eliminating asymmetries that can lead to scaling or premature wear in batteries and other electrolytic systems. The medium that carries the multi-dimensional currents may be an electrolyte, gas, gel, semiconductor, or any other medium capable of carrying current between two electrodes, and having at least two dimensions so as to enable variation in the current direction.
If the voltages applied to the electrodes are DC voltages, then the multi-directional currents have characteristics of DC currents, and if the voltages applied to the electrodes are two or three phase AC voltages, then the multi-directional currents have characteristics of AC currents. However, unlike conventional DC and AC currents, the currents generated by the method and apparatus of the invention move or rotate. If the electrodes are one-dimensional wires, then the currents rotate in two-directions. If the electrodes themselves move, or extend over two or three-dimensions, for example a plane or a curved plane, then the currents will move in three-dimensions.
SDC requires at least one extra PHYSICAL dimension in the current path which is the fluid electrolyte[Water + Electrolyte]. Through wires you can only have AC or DC in their various forms. SDC has characteristics that are found in both AC and DC that would seem to be mutally exclusive, and they are in a single dimensional circuit.
In figure 12 you see two wires. One is connected to the two positive terminals, and the other to the two negative terminals. The four switches are alternated 180 degrees out of phase. In the first half of the cycle current flows from one pole through the wire, then through the coil to all points where conductor is touching the fluid medium, then across the medium to the other wire, and on to the opposing pole. At no time are there any more than two poles with a switch closed. In the second half of the cycle the current path is the same except that its coming from the opposite end of the wire.
Think of the coil as having two single dimensional connections, and one multi-dimensional connection. Through the connection between the two power supply poles you have AC current without changing polarity. Through the connection between the poles and the medium you have DC current[in single dimensional terms. Actually its SDC].
Through the coil the direction of the current flow changes, but polarity never changes. Through the medium the current flow between anode and cathode never reverses, but its physical direction through the medium does change. It sort of sways back and forth without reversing direction. In absolute terms using one dimensional measurments you have continuous DC current flow between anode and cathode. It has all the properties of DC, but since the current flow though the medium is changing directions the current takes on the magnetic properties of AC current.
You only need to change the direction, not reverse directions.
It is DC with a property normally associated with AC.
And it is AC with a property normally associated with DC.
The effect cannot be reproduced with AC or DC. The properties are mutually exclusive in those systems. The new physical dimension in the circuit allows the current to possess an additional electrical property.
If you are having a hard time understanding don't feel bad. I can't begin to do even the simplest parts of the math, but I can visualize what is happening in my mind.
And I think 3DC [implying new dimensions] might be a better term, but Mr. Sullivan might not like the idea.
SDC current through the electrolyte in the example also carries a time component even though flow is continuous DC in single dimensional terms.
In other designs the current allows other combinations of properties that are mutually exclusive to AC and DC.
You can have your cake, and eat it too.
