Subject: CRYONICS Economy!

        I found out today that the inside diameter of a Bigfoot dewar 
(holds 4 patients) is about 1 meter.  This means that the 1 meter square 
cells I envison could hold *at least* 4 patients (not two), and Hugh 
Hixon thinks he could very probably get in 6 because of the more 
favorable geometry.  This means that the 5m x 5m room I've been 
discussing could hold 120 whole body patients (or 1200 neuros)!  The new 
projected cost per patient is now $300 per year.
 
        This much capacity (occupying only a measly 500 square feet) 
would probably last Alcor ten years.  This means I can be more generous 
in my amortization assumptions, and amortize over ten years instead of 
five.  Storage cost per patient is now $200 per year.  Because Bigfoot 
storage is scalable (you buy more as you need them) and this storage 
isn't scalable (operating costs are constant and high from day one) the 
comparison can be deceptive.  Nonetheless I believe we still compare 
well (breaking even at only 30 Cold Room patients).
 
        Let's continue to thrash out the design, and let's do it!
