However, despite the high didactic, even inflexible tone conveyed in
this note, I do not discard the idea that the person who published the
research paper, Hewitt, may have it right - that a particular plastic
line may be DEAD-stopped by an iceblock that will permit a metal wire
to penetrate.
You see, it seems Hewitt's critics have over-simplified the physics -
as teachers sometimes do.
In my view - a controlling parameter is the ratio of thermal
conductivity in the line to that of the surrounding ice.
If THIS ratio becomes sufficiently low ( for a particular diameter
of lines) then the latent heat is dissipated in side ice where it
does not contribute to the desired effect, rather than ice in the desired
plane where it is needed.
