Like Bjords opening post suggested... "Scientific truth" or the boundaries of what's purported to be truth have been pushed back decade on decade and new definitions of what is considered scientific truth have manifested. If we restrict ourselves to convention and to the so called scientific truth of today then we'll never realise the science of tomorrow.
It's true that we're learning more and increasingly weirder things, in disciplines like quantum mechanics for example.
Free energy out of thin air, without a fuel source or a field to interact with will likely forever remain a dream though.
A lot of these kind of concept generators like cold fusion have been tried and they usually don't hold under real scrutiny and independent testing, like magic tricks and sleights-of-hand.
I saw one such device make it onto the news, but it was pointed out that the cold fusion device was plugged into a AC socket the whole time and they never measured how much electricity it drew, instead of supposedly generating with cold fusion.
That's a pretty horrible logical fallacy.
Because something is being sold or advertised on a page, vaguely in relation to the topic, it cannot be trusted?
Come on, Rhekimos.
I know, that's why I said it was a warning sign, and not something that makes their suggestions automatically invalid.
But the fact that they are supposedly offering this awesome knowledge of free energy and making it widely available, and yet we don't have free energy in use, in no country or educational institution or in any basement of a mad scientist, that part doesn't make sense to me no matter how I look at it.
