Magnetic Refrigerator Needs No Electricity

This one looks a little better.

Now all you need is a Sterling Engine hooked up with it.

Yes, and two units. One to provide the heat and one for cooling, then just switch back and forth.

This is in no way overunity. It's a simple cycled heat exchange effect that has been used for near 0K cooling for decades and it's called adiabatic demagnetization. Apparently the fuzz here is using it for consumer products, but just because it doesn't necessarily need electricity doesn't mean it won't need any kind of energy to run. Hooking up stirling engine on it won't do you much good.

Actually the "fuzz" is that it's a new metal alloy that is much cheaper and more efficient than the expensive alloys used for decades.

At this time it's as efficient as current freon coolers using electro magnets so using permanent magnets would be OU provided there are no funny things like increased attraction during the metal crystalization phase.

I looked up Gladolium Refrigeration in reference to Mylow's
motor. Apparently Gladolium takes a 2T Tesla magnetic field
to activate it. Then you have to remove this field to
get it to cool. It would depend on the "magnetic moment";
the amount of attraction between the mass of the cooling
material and the magnet to determan how much work energy
would be required to get these components to separate. The
new material is an iron alloy, which doesn't sound promising
in terms of low work to get it to self run, but since
room temperature is not a universal constant it may
actually be possible to get it self run in various places
even if it doesn't self run at 72 degrees F.
