BTW the main cosmological frequencies used to spot water are
the H2O vapor absorption peaks at around 180 GHz and 320 GHz
and there is also strong microwave absorption of water at
around 22 GHz. This later one is not a simple rotational
transition but it is the most used by cosmologists, I have
read, as the others are out of range of inexpensive precision
instrumentation.
That's interesting. I wonder how water does that.
Probably along the lines of the famous 1420 MHz line of neutral
hydrogen, which is also not related to a macro rotational
transition per se, but to ortho-para nuclear spin transitions.
As for a reference for the RF-astronomy lines, I had written to
Prof. Chapin some time ago about the lack of this data on his fine
site - which is by far the best resource for water information on
the web... maybe he has updated this but I did a google search
just now for "22 GHz" water resonance, and it turns up over 400
hits including this one (but not his), with a graph showing some
of the overlapping peaks of H2O and O2:

I think the really neat experimental thing in this regard would be
to try to treat water vapor, especially water vapor carrying free
electrons (or ions), with two or more different microwave
frequencies, each tailored to the components (i.e. especially
resonant w/the proton and the -OH, the O and the whole molecule)
in order to encourage splitting-off of the proton - which
mother-nature has made conveniently 'free' 25% of the time at the
attosecond time frame, consequently only speed of light waves
would be effective to exploit this time frame.
This is somewhat along the lines of what Holraum (sic) and I are
hoping that Richard Macaulay is able to do with his liquid water
vortex tube, which has the added ability to inhibit recombination
with centrifugal/centripetal force, which is the obvious problem
with most of these schemes (immediate recombination). If he is
successful with either the 2.45 GHz alone or paired together for a
beat wave, he may be an order of magnitude better off using
overlapping specific frequencies - such as 22 in tandem with 1.64
(for the hydroxyl).
Steam might work better than liquid water, but get this: The
interesting thing is that if you get more hydrogen out than the
microwave energy put in, using water in a vortex tube - and
assuming ZPE does not come into play, then you will extract a lot
of heat from the water, which cooling effect also has a high
economic benefit for summer air conditioning.
And I think that Richard will confirm that this may be more
valuable in Texas than the hydrogen. Imagine an air conditioning
unit which is almost self-powered, from splitting and reusing the
hydrogen it produces.

...and Richard, don't forget who suggested this "Round Hill AC"
unit IF it should turn into a financial windfall when you get
Carrier & Co. into the picture ;-)
