After reading this I tried to find where I could purchase some of this
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
law of thermodynamics and Maxwell's Demon, having recently published an article
device which breaks the second law using the demon, but at very low power and
