Breaching absolute zero

-0° K

Engineers have used chains or car no refrigeration systems, to reduce the liquid hydrogen to 0.1° K.  Even magnetic cooling will not get the high June down to 0° C.

But this year I have learned about the thorium cooling system.  Where when you fancy electric field through a thorium salt in produces cooling.  Not a warming we would usually expect!

This is the thermoelectric effect.  But I do not know what happens, if we pass liquid hydrogen at 0.1° Kelvin across a thermoelectic surface we have just turned on.  I would imagine they can then get to below 0° K.

We really need a chemical engineer to try it out!
