As far as science goes, they certainly have. That you make this statement simply proves your ignorance. The data is there. Read it for yourself. A comment which I recommend to any lurkers interested in the topic. Don't believe me, don't believe Kevmo, check out the evidence for yourselves.
Again, those without nuclear engineering or physics background wouldn’t know what they are reading. Just as with you. Just as if someone read articles from years back with alchemy. We know better now but if you were to read those articles of yesterday today you might think turning materials into gold was possible. We know better now because we know what was missing from the equations.
Again, your statement that cold fusion works and is provable is ridiculous as it doesn’t pass the common sense test of where are all these cold fusion devices if it is so provable. Where? Show us one.
