X-Message-Number: 2121 Subject: CRYONICS Ice damage to cold room? Date: Sat, 17 Apr 93 15:39:25 -0400 From: I'm impressed with Brian Wowk's idea of using water ice as ballast. Here's an engineering question: do we freeze the water along the walls of the cold room before or after putting it in position? If we freeze after positioning, we need a container to hold all that water in the right configuration that will not be destroyed by the expansion when the ice freezes. If the ice breaks the container when only half the water is frozen, you'll have a sizeable flood. Otherwise we could freeze the water before putting it in the cold room. This way nothing has to be waterproof. There'd better be a drain in the vault where you keep the cold room, so decomissioning the cold room doesn't imply flooding your facility.
