A number of validations of LENR technology is going on. Various devices have been patented. Some of them have been built. A lot have been tested by more or less independent attempts. Studies are going on in defence industries, space industry and others. Various companies are supporting tests. Some universities are beginning to give courses and others get to grips with other basic studies that can have a connection with LENR. Which companies will first commercialise the technology remains to be seen, though.
