Con Perpetual Motion, According to the Critics

"Sure, Nathan, but is gravity a conservative force or not? If you can prove that it isn't, after you publish your peer-reviewed paper, you'd best start packing for Stockholm, because a Nobel won't be long in coming. On the other hand, if it is, then you're fooling yourself--no matter how complicated you make the path a mass follows, gravity is still a conservative force and you gain nothing." ---Asterix

"So SHOW the exceptions; the video does not do it."----ngepro

"You seem to be confusing power with energy." ---Asterix

"Your video is so bad that it's almost impossible to see the level and certainly not good enough to see where the bubble is. But that hasn't stopped you from continuing to repeat the same nonsense over and over. Balls do not roll up hill against gravity by themselves, end of story. I'm no longer going to stroke your ego" ---Disillusioned Guest

"The second [video] is too dark to really see what you have. The others here are right in telling you to build it better and you will learn from doing that." ---Temporal Visitor / guest

"Oh, please, you have got to be kidding me. That level is a _line level_ and a cheap one at that..." ---TinselKoala

"It's worth noting that I could build a system that appears to do this with the aid of a few hidden solenoids, sensors and a power source so a video of this happening is again only the start point of replications and achieving a consensus that it really works for everyone."---Simon Derricutt

Pro Perpetual Motion, According to the Critics

"Sometimes someone comes up with an idea that is against consensus opinion and seems crazy, but actually works. Look at Einstein, for example. If someone is prepared to spend years working on a theory, we should at least listen to it if it's put forward politely as this was."---Simon Derricutt

"...ditch the cardboard, make some proper rigid setups with believable measurements, and improve your video style".---Tinsel Koala

"One of Nathan's arguments made sense to me : 'There is at least one loophole, called the problem of proportionality. If a system can make special use of geometry to find a special efficiency in the way objects move, then physics laws might be moot, because there might be "hidden exponents".' - In my structural engineering terms I would phrase that : 'Give a structure a degree of freedom without causing collapse and utilize that free degree in such a way as to do work'."---Hafsteinn Hafsteinsson
