X-Message-Number: 2215 Date: 08 May 93 03:04:47 EDT From: Michael Riskin <> Subject: CRYONICS: More on ColdRoom Analysis To Brian Wowk: The only really important point I wish to make about the building of an ESTIMATED $150,000 coldroom is that it is a very significant amount of money for Alcor to invest at this time on an unproven idea, and we all know what tends to happen to estimated construction costs anyway. You essentially addressed my concern with your discussion of the alternative smaller coldroom concept. It should include provision for whole body as well as neuro suspension since a very significant % of Alcor members are WB's. I fully support simultaneous development of -130 suspension techniques and compatible patient storage, or for that matter, any other rationally based methods/concepts at manageable initial costs. One of my more important concerns is investing material sums of money and labor based on projected patient and membership growth. Current projections are based on insufficient data. You made the following estimates : In about a decade, a large coldroom will be at 100% capacity with 231 patients, a growth of 204 patients, broken down to 146 neuros and 85 wholebodies. Based on 6 years history, (a five fold patient increase) you extended the current patient population from 26, to 130 patients in 6 years , which I could then with the same logic extend to 650 patients in 12 years. My own more conservative estimate calculates to about 100 patients in ten more years. So, we have a patient estimate from 231 in 10 years to 650 in twelve years, to 100 in ten years. Membership growth? This is an important number since it of course directly affects patient population. Suspension membership % increases from 1989 to May 1993 are as follows: 1989 32% 1990 28% 1991 57% (Year end jump due to impending price increase) 1992 17% 1993 2% (For four months...what shall we annualize this at? One suspected reason for the low rate is potential members waiting for the Omni contest to end) If membership growth is in the 30% range, a number casually used for projection discussions, then large scale, more economical storage should be developed relatively soon. With a smaller increase, say 10%, the urgency is a lot less. We need to pursue economic efficiency while continually developing more effective suspension and storage technology. Economic efficiency for Alcor, to a great degree, increases with economies of scale, which in turn is dependent on membership growth, and the resulting greater financial resources then supports research of all types, which makes makes suspension more desireable, which attracts more members, which then requires large scale coldroom storage. As an aside, Brian, even if large scale coldroom technology was totally justified, where are we gonna put it? Lets press forward with smaller scale storage experimentation, while serious effort to relocate and improve suspension technology proceeds. types.
