The short answer is that "cold fusion" offers the needed safe containment, because it is driven by quantum mechanical effects that bypass the "brute force" approach used by "hot fusion" (tokamaks).
"Hot fusion" DOES try to build a "virtual sun" and has all the attendant problems of trying to do that. Which is also why "hot fusion" is has not "delivered" a working reactor after fifty years of research and $250 billion spent.
Cold Fusion is a movie starring “ The Saint”.
Thanks for the info. Thus if hot fusion is not containable and cold fusion is the alternative, then am thinking I must learn more about cold fusion. I would love to see fusion work. Would eliminate the waste for one thing and the waste is a problem. Spoke recently with someone in the field of fission. I asked one question. Had he read anything which would make him think fusion was possible. He did not know, and stated his side of the equation was fission. Had a professor once and in his class his comment was, We went the wrong way. Should have gone the fusion route. So I asked a question. Which was the easier for containment, fusion or fission? The answer was long from him. He did say fission was more possible because containment was possible. At the time fission containment came to be there was no containment possible for fusion. Fusion (imho) offers limitless energy, if containment can be found. Soon I hope for fusion to be contained. I believe fusion is the energy of the future, if containment is found. It will take a better mind than mine to find the piece to the puzzle.
