I think Jordan Spark's idea is a good one. If I could not afford cryo, I'd  
much rather do this than nothing. And if CI or Alcor could not accept 

brains,  then another organization might be set up to do so. ( I assume 
perfusion 
with  vitrification solution would simply be by filling the jar with VS and 
letting  diffusion work, so no special equipment or expertise would be 
needed -- nothing  but VS and a cryostat, and one cryostat could store a 

thousand brains.) Or  perhaps it's not quite that simple; I'll defer to Jordan 
on 
that.
 
Hospitals might be happy to remove the brain gently and free, if  promised 
the rest of the body for research and transplants.

The way  we do it is chemical preservation with the option to convert  to
cryopreservation.  This is the direction I have been moving very  steadily 
in
for years.  A hospital pathologist can remove the brain  and submerge it in
fixative.  It would be shipped after 1 week in  fixative.  Permanent storage
could be in fixative for the truly  indigent.  But a better option for those
who could afford it would be  to convert to cryopreservation.  The cost 
might
start at about  $20,000, but could get down to about $12,000 after the first
few due to  economies of scale. The brain would remain in fixative until the
full  cryopreservation cost was paid for, and only then go into a  dewar.
