I've published an article on ResearchGate with the title: Do the comets produce water from silicate rocks?
Abstract: It is shown there that a bio-nuclear machine, consisting to couple an exothermic nuclear reaction with an endothermic one, is able to synthesize water from magnesium silicate matters in comets. These machines would be proteins molecules. The typical reactional system is an association of Mg+C→Ar reaction with the target Si→C+O. All the energy levels has been computerized in a spreadsheet, according to all the isotopic possible combinations, and by applying basic rules. It shows all the main characteristics discovered in comets water and in chondrites, while many of them are not well understood today or identified as anomalous. These characteristics are: an excess of deuterium in the cometary water, for chondrites the richness for oxygen-16 and the excess of oxygen-17 versus oxygen-18 which defines the CCAM line, the excess of magnesium-26 and magnesium-25, the excess of nitrogen-15, the argon and the calcium anomalous fractionations. Even better, these results lead to understand chondrules and CAIs as resulting from this bio-nuclear activity. The regularly excess of the comets temperatures also find an explanation with this present theory.
There are two others articles, the first is useful to this present one
