I love how these guys never actually, say, create a website that describes the machine. If he was really so keen to have it scrutinised by the scientific community, he'd publish something to go on. You know, enough to allow it to be independently repeated? With the limited information available, and assuming there's no hidden secrets behind this device (it runs on batteries, say, and the whole thing is an attempt to fool investors) then I suspect the crux lies in the permanent magnets. They're not permanent if you extract energy from them...
