Thorium is an element which is mildly radioactive, in that it is a weak beta emitter. (A beta particle is a high energy electron.) A common source of this metal is in the form of Tungsten alloy welding electrodes, which are two percent Thorium. (Not available in all countries.)
As an experiment, I took one of these electrode wires (1/16") and rolled it slowly, to see if this would add to the energy of the emitted electrons. While looking at it closely, I could sometimes see a really thin, overly jagged tiny yellow spark shooting out a distance equal to around three times the diameter of the rod. But sometimes a small yellow spot would light up briefly, then go out. These spots were much larger than the thickness of the little sparks, but there was no visible activity between the rod and the spot, which appeared about as far from the electrode as the length of the alternately appearing sparks. Therefor, I concluded that the spots were an example of non local energy. This is a type of energy associated with, but distant from, an electrode, capacitor, ion, or nuclear particle, without a conductive path.
The majority of published research into this energy is related to the field of nuclear physics. However, I've previously placed a relatively high amount of isolated charge on some paper, using an exotic HV potential. With more experiments, I fully expect to find out how to place non local energy within a volume of water. As mentioned, doing so will not require a conductive path. But the addition of this energy to the water molecules will cause them to expand and become unstable, at some point. Then, a vibrating HV potential applied to the water will simply shake the molecules apart. "Instantly".
It's pretty obvious that Stanley Meyer left something out of his patent, "for secrecy". He says the water molecules act as "micro capacitors", yet no mechanism is shown for charging them. Perhaps this is an angle which should be investigated.
