The task of molecular sorting is discussed extensively in Nanomedicine
Sections 3.4.2 - 3.5.9.

Just a quick glance at the paper on Respirocytes:

http://www.foresight.org/Nanomedicine/Respirocytes.html

indicates that ~10^15 respirocytes (section 4.2) are capable of storing
~10^24 molecules of O2 in 6 minutes. The primary limit being the constraint
on heat removal in a "natural" human body. This can certainly be improved
upon during cryonic reanimation where one could have the body suspended in
a circulating coolant that controls temperature and removes heat. So IMO,
Yvan's claim is unsubstantiated.

Sigh. More claims that are unsubstantiated. See:

R. Merkle, "The molecular repair of the brain", Cryonics, 15(1&2) (Jan & Apr 1994).
http://www.merkle.com/cryo/techFeas.html
and the mechanical manipulation capabilities of nanorobots:
R. Freitas, Nanomedicine [Section 9.3: Nanomanipulators], Landes Bioscience (1999).
and the recent discussion between Ray Kurzweil, Eric Drexler and myself:

Thirty years ago, one could not sequence a bacterial genome (period).
Now the major genome sequencing centers can accomplish this in a couple
of days. If we really wanted to go to the moon again, I sure we could
do it within a decade, more probably within 5 years -- its a cost problem
not a technology problem.

No, the evidence seems to be there in *some* areas, such as microelectronics.
Moore's Law *does* seem to be speeding up. Go read Kurzweil's books.

While you may believe that -- it involves a great deal of hand waving
and "magic" physics (for example I'd put "quantum computing" in the
realm of magic physics -- we have hints that it might be possible but
nobody has managed to translate the fantasy into a reality except on
a very very limited scale).

Molecular sorting rotors are much more real than "quotien fields" (whatever they
are). They operate on physical principles essentially the same as the dozens
of types of ion pumps that we have the genetic sequences, and in a few cases
the crystal structures of (so we largely understand how they work at a physical
level).

Yvan, I'd urge you to read some of the background material I've cited. Its fine
to want to contribute new ideas but it isn't very useful to 'dis ideas that
some *very* bright people have thought about for between 10 and 20 years.
