If it works, this could be a very good thing indeed

I agree that this could be an amazing advance. The proof is in the pudding of course, but if you can get good vitrification without toxic antifreeze (or even a lower amount of antifreeze) you could make cryonics a lot more likely to work. Who knows, it might even be good enough that you come out in the same condition as you went in.

Once the first person walks out of a freezer or LN2 dewar alive, I figure there will be a massive increase in people signing up for cryonics. The sooner this happens, the sooner millions of people can be saved by this method. Saving people who have legally died by this method will still be controversial, but probably much less so.
