Actually Probably some Gov. are investing in cold fusion but maybe thats not the way. Some times i define what i'm doing as cold fusion because of the enormous amount of energy i think i can take out of it but is not fusion is more like taping to a huge and aways avaiable energy source. The source of this energy if you check in the end is our sun because the electrons we are taking off from the atoms is going to be charged again by the sun.
The army controls the patent office and anything that could be dangerous to the economic interests of the country or who is behind, they just came to you and say forget about this patent, if you still work on it they will make you get dismissed from your work and things like that for real.

A friend of this inventor lost his all family because he discovered how to make gasoline like with nitrogen acid and vegetable oil and was selling it for friends he received some advert but keep working on that and have being kill. In my country we see people can kill for much less.
