Re: Cryogenically Frozen Rotors

Ok, Ok, so maybe it's not "absolute" zero. :-)
As someone else pointed out, it's pretty hard to get something down to
ablsolute zero, which if memory serves me, is something on the order of
373degreesC.

I beleive they use (as previously stated) liquid nitrogen to bring the temp
down, but it's not instantaneous. The entire process, cooling and warming
back up, takes somewhere around 8 or more hours depending on the mass of the
item.  The company featured in the video I saw explained how they use temp
sensors within the container and a program to regulate the speed of cooling
and warming to prevent stress fractures.
