High pressure cryonics In this link, it is suggested to use high-pressure cryonics to freeze living cells, tissues or small organism as opposed to various and potentially toxic anti-freeze agent. The core idea is that over a certain pressure, ice is anamorphic and will not form ice crystals. Thus, organic matter will not be destroyed by said crystals.
Detailed information about the proposal can be found at this link:

I have considering self-financing the experiment. Could anyone chip in with some advice? Do you see any red flags, design tips, etc.?
 A: It is unclear what you mean by problems (technical difficulties, biology,...). One big issue here is that in your reference, they are talking about thousands of atmospheres of pressure. Safety will be a very important issue. Just look at what can happen when an airplane tire explodes (less than 100 atmospheres for sure, probably closer to 40-50) https://www.youtube.com/watch?v=1TWAR1KtYJU. The whole video is interesting, but you want to look at what happens between 1:44 and 1:54. You want to pressurize stuff to at least 20 and maybe 200 times that pressure. Any containment failure will be ugly. You can also Google what happened when Mythbusters exploded some water heaters with pressure. Very educative videos. If you don't know how to build things made to withstand such pressures, don't do it yourself. Maybe if you have access to a bunker or a very large field you could operate things remotely, but treat any pressurized chamber that you build yourself as an armed bomb ready to explode any time you pressurize it.
