A few remarks/questions:<p>1) Most modern superconductors have a high critical temperature but at a huge pressure. I can't find that detail. Is this at ambient pressure?<p>2) It looks like they are using a different material. What is the chemical formula?<p>3) The patent office don't check that the material works. They only see the paperwork. It's not necessary to give them a sample, or have the data accepted in a peer review journal, or even a working prototype. So this may been "vaporware". Is there more data available?
