Woah, here’s a funny one: http://topmagneticgenerator.com/
In the video testimonial the claim is: “It kinda works”! Here’s the video.
The same Web site links to this video and tries to sell you something for about 50 bucks. They say it’s been ready for commercial exploitation since 1992. Yeah, okay…
This one is quite typical. It depends on the imagination of the audience. Connecting a battery to something and then having it move is not over unity or perpetual motion. Anybody can run stuff off of batteries, there’s nothing special about that.
It would be special if it could run indefinitely or power something (aside from just using the batteries to power the item).
