X-Message-Number: 32265 From: Date: Mon, 28 Dec 2009 11:13:01 EST Subject: temp without LN2 Yvan mentioned the potential usefulness of transporting at liquid nitrogen temperature without using liquid nitrogen. I and others have mentioned this in the past, and in principle it isn't difficult. You just supercool dry ice (for example) to liquid nitrogen temperature and insulate well. The experiments to determine parameters have not yet been done as far as I know.
