So this Professor Shane Stadler found some new material exhibiting am magnetocaloric effect and applied for a patent seven years ago. This patent has not yet been granted, a surefire hint that there is a lot of legal work in the making which is hindering the claim to be granted...

Oh and it might take still some years for an application in household...
Any idea of the efficiency of magnetic cooling Vs Peltier cooling?
There have been some good engineering work done on Peltier coolers and it has no moving parts other than a fan to get the heat out of a radiator and such. No freon, no moving parts, can last forever.
But I don't know the efficiency compared to modern efficient freon refrigerators or the up and coming magnetic coolers.
I think Einstein was the original inventor of magnetic cooling, he actually started a company that made them maybe 100 years ago or so.
I take it back, it was a regular gas cycle:
Their actual patent:
