X-Message-Number: 2204 Date: 05 May 93 03:20:40 EDT From: Michael Riskin <> Subject: CRYONICS: RE: B.Wowks Cost Analysis Dear Brian, In your analysis / comparison of current storage costs in dewars vs. cold room , you chose to base the comparison solely on whole body suspensions. I will take it as correct that the cold room capacity is 100 whole bodies. However, at Alcor, the current ratio of neuro to whole body suspensions is 1.7 to 1.0. The yearly cost of neuro storage is significantly less than whole bodies (the analysis of such may show the neuro cost to be approximately 1/3 that of wb's). Therefore, comparing coldroom yearly costs of $15,000 to costs of 80,000 ( when 100 whole bodies are suspended , per your example) should realistically be comparing $15,000 to perhaps $35,000 ( When Alcor has 100 patients, at the current ratios, that equates to 63 neuros and 37 wb's). (And of course, that will require averaging 7 suspensions per year for ten years, a possible figure, but of course much higher than currently occuring). The then yearly storage costs of $35,000 is high, because the dewars are being amortized over 15 years as a conservative estimate, when in reality, some knowledgable people questimate that the dewars could last 50 to 100 years.And , of course, these dewars are paid for. Unless a lot of members start deanimating , it will be quite a while before even close to $150,000 in new dewars is necessary, especially if the current neuro to wb ratio continues. (9 neuros fit in one neuro dewar). When you add the cost of financing $150,000 (which could of course be much higher depending on the unknown labor factor and the screwup factor for coldroom number ONE) we have, at 7%, $10500/YR additional expense. There may in fact, be very little or no financial advantage for along time to come. In addition, $150,000 or more, plus lots of technical and administrative effort, needs to be weighed against its' lost opportunity equivalent (research, facility, suspension readiness.....). It is also possible that the coldroom, upon further design refinement, be less costly that estimated...and a much smaller initial coldroom, therefore less costly , could be built. It is also possible that the 15 year amortization for the coldroom is similiarly conservative, further reducing the yearly cost. It is not yet obvious that economies will occur in the short term (5 to 10 years) through use of coldrooms. It appears to me that the decision for the construction of a coldroom should be based on the technical superiority of patient storage for successful future reanimation over current methods of storage, to justify a large up front capital expenditure, with no apparant offset in reduced operating costs.
