Comments on Chemopreservation Versus Cryopreservation

There is some ongoing interest in plastination (or chemopreservation) as a possible alternative to cryonics (or cryopreservation) - though not yet enough for an initiative to arise that offers that service. Here is commentary on this topic: "Even if chemopreservation can be demonstrated to preserve the intricate wiring of the brain, it can be safely assumed that there will not be a massive change in demand for brain preservation technologies ... As a consequence, providers of chemopreservation will most likely operate in the same environment as providers of cryonics. That means that, as a general rule, there will be a delay between pronouncement of legal death and the start of procedures. ... There is an understandable tendency to compare brain preservation protocols under ideal conditions and favor the method that produces the best preservation. But support for either technology cannot be solely based on results produces under controlled lab conditions. Personal survival technologies should be evaluated under conditions that are most likely to be encountered by organizations that will offer them. ... One interesting aspect of the cryonics vs chemopreservation debate, though, is that it appears that some people simply feel more comfortable with one of the approaches. People who have shown the slightest interest in human cryopreservation can get really excited about the idea of chemical brain preservation. This indicates that if both approaches would be pursued actively, the growth of chemopreservation would not necessarily be at the expense of cryonics but there would be a growth in the total number of people making bio-preservation arrangements aimed at personal survival. [But] chemopreservation is not at the stage where it can be responsibly offered. The growth of this field requires a committed group of individuals who will research, develop, and implement this program. Chemopreservation does not need to be perfected before being offered (neither was cryonics) but so far most advocacy has been mostly at the conceptual level."
