Well, we are all at the same level here on cryonet.
Yet,what is said make sense:
If you supercool some water, the smallest perturbation turn it into ice.
That is because shear displacement between molecules can act as a nucleation
site to start a crystal.
The point of the CAS freezer is precisely to induce rotation in water
molecules at supercooled temperature.
The guess is that it will initiate freezing at very many places.
If there are very many starting ice freezing points, each will be near
another.
In this way, there can't be large crystals, only very many small ones.
This is not an amorphous state, only a step towards it.
It must be interesting to note that this is precisely how anti-freeze
proteins work.
So the guess thinking says it must work, note yet that is not proof that it
really work.
There is no way to get that proof outside the experiment.
If we want to know, we have to pay for the device and test it.
