The following excerpt from "Pregnant Water" (Schwangeres Wasser) in Implosion Magazine, No. 117, pp. 60-61, explains this process:
"It is a known fact that no free oxygen is present at normal temperatures, but that in the form of ozone it is loosely bound to nitrogen in the ratio of 3O2 to 6N6.
Were it otherwise, then it would not be beneficial to living things. It is only at +40°C (+104°F) that the individual O2 molecules appear, which trigger life-threatening chemical reactions in the human body and are the cause of heat-stroke for example. At about 1,000°C (1,832°F) single-atom molecules of O, identical to the oxygen atom, appear, which naturally have very specific effects. This is why, despite the hermetic seal, the high pressure in high-pressure boilers drops to medium pressure once the above atomic transformation has taken place. Similarly, it is a fact that N (= nitrogen) is not a uniform basic element, but in reality is CH2, i.e. a carbone composed of He3 (helium), wherein two atoms of hydrogen play the role of carrier-substance as it were. Furthermore, it is known that gaseous water and liquid water are quite different things. Gaseous water is OH2 and liquid water (OH2)6. The strong action of gaseous water, for example, follows from this, because two free action quantities or points become active, whereas liquid water has no action quantities, because all the action points are filled with H."

1. It is a known fact that in high pressure boilers a reflux from high to medium pressure takes place under certain circumstances without the hermetic seal being broken. Up to now this occurrence could not be explained and because of it the manufacture of miniature pressurised boilers was abandoned, which meant, of course, that veritable mechanical monsters had to be put up with, which consumed a great deal of space and material.

Like the beads of carbon dioxide in water that has been warmed, through the strong influence of heat the residual substances shrivel up after the separation and precipitation of the higher quality constituents. Due to the high pressure the outer envelope or the carrier-substance will be crushed and in this way the de-energised elements released.
