Stepping forward -
Helium dilution refridgerators can cool down to 1 mK or so.
The liquid still has KE - can it do work??
Can the the ground state energy of a quantum oscillator 'do work' or is it non-workable energy???

A list member asks me privately the following:_______________________________________________
Helium remains liquid due to this non-removable energy.Let[s see how the list responds.
Superconducting currents remain mobile with non-workable KE.
help me understand
He is at 4K so al I would need is a system cooler - I don't know what
that might be but....
Superconductors could be at even greater that 4K
