This is another reply from Frank Grimer, whose email to Vo is
getting bounced again in cyberspace - between the UK and USA - so
he has sent it to me to post ... [guess the powers-that-be
...consider moi, i.e. present-company to be more in the genre of
court-jester than bona-fide threat ... as well they should <g> ]
We have a situation where over time - electrochemical hydrogen
bonding of water has changed its phase - and increased the
density (compressive strength) decreased the volatility (so no
vapor is available) and voila ---> This negative pressure arise
in a formative nanobubble, which becomes the substitute for
"real" pressure - which in turn allows for this hypothetical
species: "virtual-ice-8" to become stable at STP - for at least
a short period of time.
I like the - "decreased the volatility (so no vapor is
available)" - bit but I would prefer the word cavity
to the word bubble. To me "bubble" conjures up the
concept of positive pressure whereas here we are dealing
with negative pressure (high pF).
I also like the idea that the ice VIII is stable for
a short period of time - like Nitrogen triiodide.

8.2 gigapascals = 1,189,309.45 pounds per square inch
Methinks that is a high pressure - as befits its
"diamond" like structure and high density,
Frank
Yes, obvioulsy meant "low temp/ high pressure" -
...but that pressure is so very high, even the open-minded
optimist doubts that the electrostatic force could accomplish
it....
OTOH ... there is Chris Arnold's plasma device which he has found
will produce diamond film from carbon... so who knows....
