My overall idea was simply to minimize your dewar's convective losses in the same way that you were reducing your conductive ones. If you modify your design so that (a) your dewars are airtight insulated all the way down to the floor and (b) the boiloff nitrogen is vented to the outside only through a narrow/long opening, you'll have achieved everything that I was thinking of. -Ken Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=7683
