Dear Mr. Brown,

I was delighted to see your posting to the cryonet --#12042: cryostasis
careers yet? [David M Brown], where you wrote:

  I have a question that you might be able to help me out with.

To my knowledge, the cryonics organizations do not make their own LN2, but
purchase from outside sources.

I have often wondered if a reduction in suspension cost might be achieved
by a cryonics organization that made its own LN2; that, in fact,
established an affiliated business located, say, in the mojave desert,
(perhaps using long-term uninterruptable, reliable, and free (yes, there
are non-trivial capital costs) solar energy) that produced liquid nitrogen
for sale in the LA, San Diego, Pheonix, Tucson, and Las Vegas areas, and at
the same time maintained a patient storage facility on the same site.

Such a facility could be jointly operated by any or all of the the current
cryonics oganizations, thus permitting an across-the-board reduction in
suspension costs.  The facility could be built and operated by members on a
volunteer or suspension-for-work exchange basis--a sort of cryonics
kibbutz.  The possibilities are endless.  (Heck, to take it just a bit over
the top, you could turn the place into a cryonics theme park and winter
season snow-bird resort.  "We treat you special.  All the way to the
future."  Those retirees are all potential suspension clients.) 

On the internet, I found the advertisments shown below.

>    Pos. 26 - CRYOGENIC GAS plant (skid mounted); yield: 30 MMCFD;. price:

I've sent off for more details on the above, to further my investigation,
and I wonder if you might help out with my ongoing "analysis".  I'd like to
find out what it costs to run such a plant, and what the market for and
price of the output would be.  I wonder about energy costs, and how a
dedicated solar energy system might effect costs, and how such a system
might be employed as a direct power source (no conversion losses) for the
LN2 plant.

I gather, from your posting, David, that you're exploring career
opportunities.  This might be something you could build into a career,
while at the same time making a significant contribution to the advancement
of cryonics.    
			Best, Jeff Davis
