Yes, good topic.
I had a guy that brings me computer parts all the time, then he started bringing me some hard drives that were torn apart. He said was working on making a fan run with the magnets. I'll bet that he saw the same video.
Just remember that energy is a constant. You can not create more energy than what is being consumed, and you can't destroy it either. The trick is the end result rating of efficiency. We had an old timer at the local saloon a few years back that fell for one of those adds about the space heaters in the Amish built cabinets. He paid $600 for a space heater that has an efficiency rating less than a $30 oil filled electric heater. But he fell for the hype. Did he save money on his heating bill? yes he did, because he heated whatever room he was in rather than heat the entire house. The same could have ben achieved from that $30 oil filled heater. I looked them up on consumer reports and not only were the efficiency ratings lower, they were a fire hazard if they tipped over where again the $30 oil filled heater would shut off automatically if it tipped over.
My point? When anyone touts the energy saving principles or even the never ending energy or perpetual motion, always listen with a skeptical ear.
Things to look for that are making improvements are better batteries for energy storage, cheaper solar panels to cut the initial investment in setting up a system, and gulf stream turbines.
One last note. Perpetual motion is a fallacy, or is it? Maybe it's just relative. The sun bombards us with energy every second of the day. It has done that well before the day I was born and I am fairly certain that it will do so long after I have passed. Therefore to me there is a never ending source of energy if I can just harness it cheaply enough. So, relative to me and my lifespan, there is free energy all around us.
