Paul is stuck at about $300K in pledges cuz he's now tapped everybody
is into cryonics. When asked at a Bay Area Cryo meeting about his
it was to the effect that a successful revival would spark interest in
cryonics. I'm in the nanotech camp myself and see little point to the
Promethius project. IMHO it will take far more than $1M in research to
accomplish the putative task, and it may actually not be possible.

Two hearts, two failures. Turns out that the demo prior to the festival
involved 60 seconds immersion, not 17-20 minutes. Visser claims 45
in South Africa but there are questions re the apparatus used. It is not
clear that 60 seconds results in anything like LN2 temperatures in the
and a small crack across the neurons in the heart would prevent revival.
Visser goofed on the first law of demos: CHANGE NOTHING!

The reason she tried the 17 minutes is that Paul Segal of Biotime told
the previous day that he would believe her results if a minimum of 15
immersion were done and she agreed to do this (I was there, heard the

Did successful demo of this last year, cooled to around -2 C. Was there,
saw it, etc. Plunge into freezing bath NOT the technique used.

Not relavant here. Ask me when we are face to face and I can give more

Hextend, going into FDA trials with human subjects. I have prospectus of
latest stock rights describing in detail. I bought at 5, currently at

This weeks cryo meeting at Ralph Merkle's house. How about coming to
the meeting??
