QUOTES:
". . . back in 1989, estimates for the initial reproducibility of the
Pons/Fleischmann effect ranged between 5-10%. . . .
But perhaps the most exciting development in cold fusion research is
that, at least for SRI and Energetics, the reproducibility rate has
climbed to 73%! Meaning, when they set up the cells, and attempt to
induce the cold fusion effect, they can make it happen 73% of the time.
So what’s happened? The last two decades of research point to two
fundamental criteria.
First, for the reaction to occur, hydrogen isotopes (deuterium) must be
loaded into the metal to at least 90%. This means, for instance, the
palladium metal must be super-stuffed with deuterium atoms in an almost
one-to-one ratio with the palladium atoms, causing the isotopes to crowd
up tight together.
Secondly, these isotopes must then be induced to “move”. . . ."
The author did not mention improved materials from ENEA. I think that is
the biggest factor in improved reproducibility. I cannot judge whether
materials alone can bring about dramatic improvements making the devices
suitable for practical applications. Perhaps that will call for
something like Rossi's techniques.
