Trouble is, he thinks the videos are conclusive evidence. I can provide links if anyone's interested (youtube only, no desire to promote these sites) How do you demonstrate to someone that what they are watching is not proof when they don't understand what you're talking about? Example - someone takes a 'fuel cell', plugs in into mains power and exclaims how great it is because it's producing bubbles. Apparently this is a working example and therefore conclusive proof. He just does not comprehend when I say that it demonstrates nothing. Arghhh :/ This raises another question then - how can seemingly intelligent people fall for such bad science. Why don't people understand the basics of chemistry? Why on earth can someone who has completed a university level education be so lacking in the fundamentals of chemistry?
