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.
