Several things of interest about this patent. The claimed inventor was Murray, for IH.
The application was in Dec 2016 and it talks about extensive research and testing showing excess heat.
I didn't read it all as it was so vague, but I got the impression it was as novel as a left handed door.
It claims all the known materials/isotopes that others have posted but I saw no details of what one should specifically use or do. It looked to me that H were trying to cover every future possibility known at that time.
Lots of luck for anyone trying to build a working reactor from the patent.
