Although most of those who post to "overunity" newsgroups actually do realize that - in the end - there is no such thing as perpetual motion. Or, the free lunch is never free, if you prefer. OU has become one of those legendary quests - like that for the holy grail, which as a meme, must fulfill some deep and hidden psychological need. In that regard, lets admit that the fascination with overunity is not only something like ART itself, it can be entwined and merge with art into something that moves to a higher plane ... well... maybe just weird and wonderful.
That must be why I find this little YouTube vid to be so fascinating - and given that some of the sculptures will run for 40 hours or more, this guy could fool many free energy optimists, if he chose to pass it off as more than art. He is careful not to do so. https://www.youtube.com/watch?v=ROP45rjvOHg
