Subject: LN2 generation

Jeff Davis has questions and suggestions concerning the possibility of 
cryonics organizations generating their own liquid nitrogen, and perhaps 
their own energy.

This has always been a long-term goal, but not yet anywhere near our means, 
even if all the organizations could combine. Besides capital costs, the main 
costs in generating liquid nitrogen are for electrical energy and water (for 
cooling). These costs, on the scale of our present operations, far exceed the 
cost of buying nitrogen from commercial suppliers, even disregarding 
operation and maintenance. 

Generating our own energy is also pretty much out of the question currently, 
although I have always hoped eventually to have something like a thermopile 
system which, once installed, would have near-zero operating and maintenance 

However, if Mr. Davis should learn of someone who wants to sell a liquid 
nitrogen generating system at sacrifice prices, that just possibly might be 
of interest, as a backup system.
