Moin Frank,
You make a good point, the spectrum should be different. I don't
remember off the top of my head if this was ever measured or not, to
tell you the truth, but it would seem logical that any well equiped
researcher would do that. It is cheap and easy enough to do. All of
the early stuff that I have read states that the light is in the UV
range, but that was only for normal water. Schaeffer, as far back as
the early 70's, and Griggs in the early 90's both reported blue steam
coming out of their devices, and I asked at the time if they had turned
out the lights to see if the steam was actually emitting light, but I
never got an answer. At the time, I was trying to establish the fact
that the hydrogen/oxygen bonds were being broken, and that the steam
contained radicals that were burning when exposed to the oxygen outside
the machine. That much and more has been pretty well established since
then.
As for URLs, my collection was destroyed when I moved to Europe. I had
two copies of my website which contained nearly all of the URLs, and
went to great lengths to ensure that they would be safely treated during
my escape from the US. The story of how they were destroyed is so
unbelievable, I don't even want to think about it. I haven't had the
time since then to do the work again. So it goes. I do remember
sending copies of the website to a couple of people from this group.
Maybe somebody still has a copy, and can send it to you.
