I searched the forum but didn't find any threads on the topic and wonder, has anyone heard anything about major manufacturers other than GE working on magnetic cooling R&D? Of the technologies being studied it seems magnetocoloric alloys would have the best chance at commercialization.
There's a little blurb on LSU's website about their research and it mentions that local investors are involved. I'd assume the investors are there to fund work aimed at growing the IP to a point where it can be licensed.

And GE put out a few videos a while back that show R&D work being done in the lab.

Sorry about not posting direct links, I'm still restricted due to being 'new' on the forum. I'll update the post as soon as I'm permitted.
