It does state they did considerable research and testing and that it worked.
from: http://www.freepatentsonline.com/WO2018119352A1.html as you recommended.
Again, where does it say "they did considerable research and testing and that it worked" ??????
Let's see your reference and exact quote as you fondle ask of others
All I see about any tests is : "In existing systems and tests- including heavy water electrolytic cells, heavy water codeposition electrolytic cells, Pd lattice plated devices with hydrogen and deuterium gas, and solid state reactors.... "
and  : "In the research and tests surrounding anomalous heat generation in various physical configurations - e.g., wet cell, gas charged tubes, and dry reactors - have been investigated."
and the only thing about research  is: "research in this field has largely been inconclusive."
There is nothing there that says they did the testing nor the research.
You are just babbling on, as far as I can see and making things up.
