What applications are there for Absolute Zero?

Question

theres all this talk about scientists trying to get tempratures as low as they can to Absolute Zero.. my question is what can this lead to if they are able to go down to absolute zero?

can it help studies in medecine or physics or anything? Besides in the name of science are there other reasons why people would want to be able to go down to Absolute Zero?

Answer 1

Superconductors.

This would help everyone, as transmission lines would have no losses and people would benefit through the environmental impact and possibly reduced power bills.

The Hadron accelerator uses supercooled electromagnets as well.

If a conductor is cooled to 0 degrees Kelvin, it has no resistance. No resistance means no losses due to heat dissipation. Therefore smaller conductors can be used to carry larger currents, saving costs on copper or aluminum used for the conductors. This and no losses saves a lot of money.
