X-Message-Number: 1982 From: Subject: CRYONICS A way to freeze y'r ass Date: Thu, 18 Mar 93 10:01:23 PST Mike Darwin asked of me: >>From Mike Darwin > >I was told that at the Alcor board meeting you made some comment to the >effect that you had some idea of how or where I could get access to a >-130*C environment. Would you please share that idea with us? I already passed this on to Mark Connaughton (an officer of Cryovita) but CryoNet.folks might have some improvements to suggest. My suggestions is to stand up 4 or 6 4x8 foot sheets of either 1 or 2 inch styrofoam and tape the joints with duct tape. Use one sheet for a floor and protect it with a sheet of plywood. This give you an open top room 4x4 or 4x8 and 8 feet tall. For the time involved, the heat loss through the wall should not be a problem. Get a tall step ladder which can go over the wall. Spray LN2 into the room till it gets as cold as you want it. Go up the ladder, and down into the room. The main advantage of this approach is that someone can watch from the ladder. If the test subject keels over (or quits moving) rip the tape off one panel and let it drop. This beats the heck out of trying to get a person out of a bigfoot dewar. :) Best of luck. Keith PS, Public thanks to Mike for letting Alcor know about a possible problem with the perfusate. KH Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=1982
