They are probably freeze-drying the bodies for a long time to eliminate the liquid in the body. Then I suppose the bodies might be fragile enough to fall apart easily when shaken. In any case, this is not a problem for cryonics patients. A large fraction of the water in the body is replaced with various chemicals; but the mass and structure are preserved. While a rose or a banana frozen to LN2 temperature can shatter easily, a preserved human or animal body at that temperature is very hard to break. Animal bodies are reinforced with bone and fiber and are much more solid. Alcor's patients have been exposed to an earthquake in Southern California, transportation by truck to Arizona, and the daily vibrations of vehicles being driven past the building. In the situations where we have had cause to examine patients (transfers to new containers, for instance) or the more frequent times when we have examined preserved animals for various tests, we have never seen any evidence that they are vulnerable to being shaken into dust. Finally, someone else pointed out to me that the "Mythbusters" television program actually tested a pig frozen in liquid nitrogen and were unable to damage it much more than chipping off a few exterior pieces.

Obviously, liquid nitrogen can make certain things very brittle. I'm sure you've seen the videos of a rose being flash frozen and shattered with a hammer, or a similar one with a balloon. Well, I read that there is a Swedish firm called promessa that destroys bodies this way, by dropping them in liquid nitrogen and subjecting them to "light vibration". How vulnerable are patients in a cryonics storage vault to this? Will the hum of nearby machinery or a small earthquake cause the patients to turn into a pile of shattered pieces? Here's the website where they show the process http://www.promessa.se/facts/illustrated-description/?lang=en ----------MB_8CD0988CD8808BB_14AC_33CBE_webmail-m080.sysops.aol.com Content-Type: text/html; charset="utf-8" [ AUTOMATICALLY SKIPPING HTML ENCODING! ] Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=32766
