After reading this I tried to find where I could purchase some of this material, but was not successful. Building and testing it is a bit of a problem if the magetocaloric material is not easily obtainable.
Also is there ANY theory as to why it should do what is claimed to do. I cannot figure out what the mechanism would be, although I am very familiar with the second law of thermodynamics and Maxwell's Demon, having recently published an article on a device which breaks the second law using the demon, but at very low power and efficiency.
