Thanks for the information, PerC
I didn't know about the restaurant freezers on liquid nitrogen. I will try to find such with their costs. I wonder if there will be such, that manage to hold an entire human, or will have big enough door. I also,simmilarly to you believe, that in the future, the science will allow the head to survive, and the rest of the body may not be needed. However, if we manage to find a way for cheap preservation of the entire body, why not keep it also.
The custom made dewars, cappable of repairment is also a very nice idea. It seems, that the CI really have went very further with the knowledge in cheaper vitrification.
I noticed also, that there have been attempts to build cryonic companies in cheaper countries, such as China and India, and the attempts has failed, probabbly accompanied with the loss of not a small amount of investor's money. Probabbly there are also other unexpected big obstacles.
There are some which are in formation, but I don't think any have openned or failed outside of the US and UK. It takes a decade to organize something like this. Look into Stassis Systems Australia.
