Well,the "For Dummies" series
publishers might be a good backer,
but I think the image of stupid
people being around forever will
turn off many who of course don't
see themselves as being stupid.

(The ultimate series book would
be the Special Edition Using the
Complete Idiot's Guide For Dummies
Unleashed!)

Of course,others have said that
liquid helium temperatures(<2 K),if
possible,would be ideal.While dry
ice temperatures are above either
of these.

Have there been real projections
for 4000-year suspensions(on par
with ancient mummies) and just how
much decay would have occurred at
relevant temperatures,or is everyone
sure that in a couple centuries
everyone from James Bedford to
Luna Wilson will be up and about
and appearing in cryonics
commercials?

I gather that the cylindrical shape is 
an innovation...sacrificing floorspace
efficiency for thermal efficiency?

So in effect,CI did not have a
long-term-storage capacity as
large as its frozen-patient
inventory until this unit was
completed?(And after one more
is added,this situation will
recur).

I don't know how likely a
"big spurt" is.But right now
with the temporaries empty
you're ready for the next few
cooldowns.

Not really.If a company sells
its former premises and moves
to new quarters,it is still the
same company.

That makes a huge difference.
The natural processes of how
bodies maintain themselves are
uninterrupted,there is no new
body coming in place of an old.

Something to make the minimum
necessary accomodation to when
necessary.There's plenty of room
short of infinity.

Most recent "cuts from the permanent
team" include people from Usenet pioneer
Jim Ellis(aged 45) to 101-year-old Gina
Cigna,who retired as an operatic soprano
before Ellis was born.

A number of Internet pioneers have died
young,while oldsters you'd think less
equipped for this century and those to
come keep on going.I hope the Net's not
bad for survival.(Well,I did once help
get the cops to a guy who'd announced
his suicide on IRC).
