To repeat: in desalted seawater, there are 5 atoms of 18O per 1000 atoms of 16O, which is about 15 time higher than the expected percentage of HDO to H2O... and this is much higher than most people realize, plus - and in addition to the starting percentage being higher in ocean water, it is much higher yet when the water source comes from hot springs or is extracted from vegetation. And some (but not all) of those same distillation or enrichment processes which enrich in D are even more effective in enriching in 18O - so it is easily possible to get 100% 18O ahead of getting a usable percentage of D.
This looks like very important observation. Further, the source of D2O may be from a reactor, post tritium separation, in which case O17 may be even more abundant than O18, and trace tritium still present. Looks like mass spec. is the only way to assess what you have too.
This could be an opportunity for some organization with a mass spectrometer to make a huge contribution to the field by providing a *variety* of D2O types to LENR researchers that are fully assayed. This obviously could eliminate a huge variability in results, and provide important lines of research as well as new experimental controls.
