I would imagine temperature controlling a long cable woujld be no easy
task, although I guess one needs to define the accuracy needed.

Maybe if the cables were burried sufficiently deep, there would be no
short term changes of temperature, since the temperature underground
is more contant than on the surface of the earth.
