(Updated continuously). Today Andrea Rossi was granted a patent on his LENR based heating device the E-Cat. I have not yet had time to study the patent further, but I just wanted to make it available here on the blog as soon as possible.
Note that LENR is not mentioned explicitly, but also note that the contents of the fuel mix are specified — lithium and lithium aluminium hydride as fuel and “a group 10 element, such as nickel in powdered form” as the catalyst. This is important since fuel and catalyst specifications are lacking from an earlier patent application by Rossi on the E-Cat, as far as I know.
