X-Message-Number: 22301 From: "John de Rivaz" <> Subject: transport cooling Date: Wed, 6 Aug 2003 11:13:32 +0100 There has been some discussion on Cryonics Europe <> about transport cooling, or to be more precise maintaining a low temperature during transport. It appears that up to now airline companies have not objected to dry ice, but rules are arbitrary and subject to change at a whim and the situation with regards to dry ice may not always be so convenient. Although cargo holds may be at the temperature of the upper atmosphere during flight, and therefore at an ideal temperature for our purpose, most of the overall time of transport will be in waiting areas and so on. This is usually quite hot. One possibility not mentioned is the use of the gel used in wine coolers and similar products. This is usually a liquid in plastic containers shaped to go around a bottle of white wine. When placed in a freezer these assume the temperature of the freezer. When placed around a bottle of wine they keep it cool. A similar idea is used to keep frozen food cool during checkout and transport home when buying from a supermarket. This may be totally innappropriate for cryo transport, but no one has specifically excluded it as far as I am aware. -- Sincerely, John de Rivaz: http://John.deRivaz.com for websites including Cryonics Europe, Longevity Report, The Venturists, Porthtowan, Alec Harley Reeves - inventor, Arthur Bowker - potter, de Rivaz genealogy, Nomad .. and more Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=22301
