Subject: More on Cryostats & Dewars

Ben, 

You posted as follows yesterday with the following hyperlink:

"I recently posted a report concerning the
status of the Cryonics Institute Cryostats on the 
CI website, which may be of interest to the cryonics
community at large:

http://www.cryonics.org/cryostats.html 

That was some interesting reading for me, and answered a few questions I've 
had for some time about cryostats & dewars in general, and CI's setup in 

particular. Thanks for writing that up and pointing it out.  However, I noticed 
you 
did not mention CI's smaller "pet dewar(s)" purchased from one of the few 
manufacturers of this equipment in the country.

As you and Robert Ettinger will remember, I operated a 90 liter dewar (for my 
little buddy, Diesel, now in CI's care: http://boardwatch.org/david&
diesel.jpg
 ) several years ago that I had gotten secondhand from Duke University. I've 
decided to donate it to CI and have it delivered to Detroit in the next few 

weeks for whatever use you might find for it including perhaps as backup for the
DNA sample storage or for "pet patients," or as "standby equipment" for 
onsite dry ice storage, etc.  I will email or telephone you and Andy before 
shipping it.

I happen to be reading the book "Oxygen: The Molecule That Made the World" by 
Nick Lane and ran across some trivia on dewars that may be of interest to a 
few regarding the "invention" and the naming of these oversized thermoses.  I 
scanned pages 120 and 121. Checkout the second full paragraph from the first 
page:

The book is good and is applicable to cryonics in some respects. More about 
it (in the form of reviews) can be found here:
