from international espionage, etc. I would think that other countries and governments would love to get their paws on this technology especially for their military and industrial uses, etc. As you know some countries don't care about patents and will do whatever to acquire a new technology. I am also surprised that the US military has not protected this only for military use and is allowing it to go into the public domain, especially since it was financed largely by government money over the many years. On the other side of the coin I am glad that it is in the public domain which hopefully will allow a lot of us to profit from it if all goes according to Hoyl. Something to think about.
