Have you encountered Perpetual Motion Disease (PMD)?

[Q_Goest]

Ralf is in a wheel chair now. He’s an old guy, over 80 but still has a strong desire to do things like run his machine shop and invent stuff. His shop only consists of himself and one other guy though he’s not able to work in the shop any longer due to his age and failing health. He’s got this thick accent, as does the guy that works for him. Kind of a Pennsylvania Dutch accent I guess but maybe not. Something more European but I can’t place it.

Ralf called me about 4 weeks ago and wanted me to help him with an idea he had for electrical power generation but he didn’t want to disclose it because he thought he had something really unique. He tried sending letters to executives at our company, but as you might imagine, he got no response. Knowing he probably had an idea that was basically a perpetual motion machine and therefore impossible to make work, I nevertheless told him I’d look at it and tell him what I thought.

Friday morning Ralf finally got a nurse that was able to drive him to where I work. She wheeled him in and I took him into a small coffee shop to talk about his idea. As soon as he started in on it I could see it was a perpetual motion machine and my heart sank. I was really hoping he had something original but as an engineer, you can generally identify a perpetual motion machine as easily as a doctor can identify a broken leg. It might take all of a few minutes but it’s always as obvious as the back of your hand.

I spent almost an hour listening carefully and talking with him, trying to get him to understand the energy balance of the system he was proposing. A few times I tried to remind him that we’ve known each other for a very long time and I honestly care about him and his business. You could see just how much work he had put into this and how much it meant to him. He had scale drawings made up and all sorts of details to describe how it would work. He really believed he’d come up with a way to make energy from a contraption that looked like a Ferris wheel that took water from the top to the bottom, hooked to a generator, and a pump that returned the water to the top which was powered by a battery charged by wind or solar energy. The whole thing was convoluted to say the least. To make it that much more difficult, he’s hard of hearing and I’d have to talk loudly to be heard.

Eventually it all got through to him. He sat there staring at the plans he brought for his invention saying nothing for a very long time. Then he’d get up his courage and ask a few more things and try to point out how it could be made to work. Each time I’d try to explain as best I could how energy can’t be created out of thin air and where the energy had to come from. He slowly started catching on. I felt bad for the guy and sat with him there while he pondered how to make this thing work.

Eventually he gave up. I know he realized I wasn’t trying to just shoot him down, I was trying the best I could to educate him and explain how his invention couldn’t work in technical detail sufficient for him to understand. Before he left he even apologized for taking up my time which I quickly brushed aside and thanked him for stopping by, shaking his hand before he packed up.

I’ve seen this phenomena many times before. People come up with ideas for some invention that puts out more energy than it consumes. It’s hypnotic. When I was younger I had a friend at work who also has an engineering degree and realizes there’s no way to create a perpetual motion machine but he still thought about it all the time anyway and told me about the ideas he had. This went on for a year or two. He KNEW there was no way to make it work but he kept thinking about it anyway and constantly came up with new ideas. I think he’d tell me about these ideas to help him understand how they couldn’t work because he couldn’t quite figure it out himself. But there are a lot of people that seem to get caught up with the idea of creating energy out of nothing. They get totally wound around some idea and can’t let it go.

So what do you call it, Perpetual Motion Disease (PMD)? Have you seen it too? I think the vast majority of people with PMD honestly believe in their ideas, they’re not just trying to scam anyone. Sure, there are scammers out there trying to take advantage but if there wasn’t anyone with PMD, there would be no one to scam! There seems to be a genuine belief, not unlike an unfounded religious belief, that grips people predisposed to PMD.

I had a former student of mine waste an hour of my life with his machine. He had a typical "torque fallacy" machine, a wheel where the mass on an extended arm on the right side lifted the mass on a short arm on the left. I pointed out that the mass on the short arm would then need to be lifted the extra distance where the long arm started. He thought that the momentum in the system would compensate for that

Not understanding Physics does not seem to be a barrier. I do believe you are correct in detecting a psychological issue. PMD has a good ring to it.

It dawned on me that my guy thought there was the kinetic energy in the system, and then there was also the momentum; that is, you could take out the KE but keep the momentum, as though they were two completely different ingredients.

I finally emailed him what I thought his idea was: it was like he was looking at a mountain with several paths to the top. No matter which path you took, you would end up at the same altitude as all the others. He was essentially proposing to me that he was going to blaze a trail to the top of this mountain, crossing different streams, going over different rocks, and at the end, his path would be at a higher altitude than all the others.

That was the last I heard of him.

 

[Q_Goest]

That's a good story! It's always easier to deal with folks with PMD if you don't know them.

 

[intwo]

Ralf sounds like a nice guy. Although his perpetual motion idea was unsuccessful, maybe he will use the information from your meeting to build something else.

I have an uncle who shares his proposed perpetual motion machines with me. He wants to put cars in vacuums or something like that. I used to (politely) point out problems with his ideas, but he got extremely offensive. He told me that I had no clue what I was talking about because physics cannot be proven and that "just because go to school, doesn't mean that know anything more than anyone else." I told him that the science cannot be definitely proven, but it seems to work in our current system, so it must bear some weight. He became more aggressive and continued to criticize my education, so now I just sit and listen.

 

[Q_Goest]

Ralf sounds like a nice guy.

He's a sweetheart. And his work at the machine shop is always compared to Swiss watches.

I have an uncle ...

That's a tough one because he's "your uncle"... Unfortunately for your uncle, the rule of "Obey your elders" gets trumped by the law of "conservation of energy". <sigh>

I have had a great deal of trouble over the years with people that claim that "insiders" are suppressing energy-saving devices. I once told a stubborn brother-in-law that I had bought a bunch of fuel-economy devices from JC Whitney and had bolted them onto my '65 Jeep, but it got tedious having to stop over and over and siphon excess gasoline out of the tank so it wouldn't overflow. He was not amused.

 

[Q_Goest]

... energy-saving devices.

I heard about those things. They were discovered on that disk shaped craft taken from Area 51.

 

[OmCheeto]

There was once* a perpetual motion device posted here at the forum. For the life of me I couldn't figure out why it wouldn't work. So I went out on my back porch and built it. Within 3 seconds I understood why. Unfortunately, when I came back inside to post why it wouldn't work, I discovered that the thread had been locked.

I think people with PMD should all be required to build one first, and then explain to the class why it didn't work, so I don't have to waste any more, oh so valuable, empty tuna fish cans.

Those little warts on the tuna fish cans are magnets, aren't they?

That's too funny!

 

[JonDE]

Tell someone they can't do something, and suddenly its the only thing they have ever wanted to do. I think this is almost a normal part of human behavior. Both a weakness and a strength. How many FTL threads have there been on this forum? I think it amounts to the same thing as PMD.

 

[MacLaddy]

This makes me think of the historical study of alchemy, trying to transmute lead into gold. How many people did that obsession drive over the edge?

I guess energy is our modern day gold.

 

[OmCheeto]

Those little warts on the tuna fish cans are magnets, aren't they?

That's too funny!

Yes...

The design reminded me a bit of a Perpetual Motion device I designed sometime earlier. Mine was based on the assumption that superconductors exclude magnetic fields. I of course didn't build one, knowing that PM devices are impossible. But I did scratch my head regarding the Meissner Effect for a few days. Never did figure it out.

But then again... Right after I posted an image of the device on my last science forum, the forum went down... permanently.

Trust me, once they get started discussing it, they never ever stop.

 

[Chi Meson]

Trust me, once they get started discussing it, they never ever stop.

It's true. My guy finally got over his "torque fallacy" machine, and then came up with a "perpetual waterflow" device. The kind where a flow of water (top reservoir to bottom reservoir) causes a float in the bottom to rise, which in turn lifts water into the top reservoir.

He just would not let it go, and he kept thinking his ideas were brand new, that he's never seen any idea like his. I told him that he not only didn't understand physics, but he can't do a decent search on the internet either.

I think that highlights two of the symptoms of PMD.
1) The person doesn't understand energy and how it has to balance.
2) The person thinks their idea is the first time it's ever been thought of.

PMD also induces the sensation of winning a lottery in the victim. It must be a wonderful feeling, but there's always the 'day after' sensation that arises when realization sets in.

 

[OmCheeto]

I never met such people yet; or at least they never discussed perpetual motion with me.

I almost met one once. In that eX-Filed forum I discussed earlier, someone brought together the fact that pistons of different sizes, under the same pressure, would have different net forces applied. So he proposed sinking his device into the ocean to generate huge amounts of free energy. I looked at his drawing and told him that it would work through one cycle and then stop. I also told him that I had a fish tank into which I could submerge a mini-model and prove this. He said it would only work if it were submerged under hundreds, perhaps thousands of feet of water. So I asked him if he required financial assistance for such a huge venture. He of course said yes, at which point I stopped conversing with him.

But I did google his name*, and discovered he lived only a few miles away from me. I now avoid that section of town like the plague...

*He was so confident in his idea, he gave out his real name.
Gads. Googling the concept and my town, still lists him on page 1.
How could I have forgotten that name...
OMG! His invention has it's own Wiki entry!

[DragonPetter]

I met a guy in this "hippy" area of a town in Norway living in an apartment. He was trying to build a PM device in the basement of the apartment and he tried talking to me about it.

From the start, he considered me an adversary because he knew I studied physics. He told me that physicists are not trained right, and we're only taught to think in one way. I felt that was ignorant and insulting, but I let him go on for over an hour since he was my friend's brother and I wanted to be his friend.

His idea consisted of magnets and a motor . . some kind of wheel. I picked apart his idea a few times, but he always would counter my attacks with pseudo science arguments that I didn't know enough about to really be able to refute him. Basically he said that there is vacuum energy that must be sapped, and so it won't violate the 2nd thermodynamic law.

Obviously vacuum energy is real, but how a wheel with magnets made in a basement shop is going to tap into quantum energy is beyond me. The sad part is he was not very rich, living as a hippy, and he told me he spent large amounts of money on the magnets.

I, too, was impressed by Q_Goest's understanding and patience.

I've learned the hard way that those suffering from PMD really, really don't want to hear a woman tell them their idea won't work - quelle horreur! Well clearly my sampling is biased since I've never told anyone that as a man .

Gender issues aside, now I just say, "You should build a prototype to see if it works!" At least that way, the local hardware store gets something out of it.

[Antiphon]

I'm a tad taken aback by the tone of some in this thread. It's not a mental disorder to want to make a breakthrough in science. Being stubborn about it isn't justification to be treated with disrespect by someone with knowledge in the field.

I suppose any of you would direct this level of scorn toward Issac Newton because he was trying to turn lead into gold?

How many of you have a hobby where you're not good at it but enthusiastic about it?

Should you mock people having fun overclocking and crashing their computers because they're violating the design rules of the computer?

Lighten up. Failing to make PPM machines is fun and a good way to learn physics. If it irritates you, pass these folks on to more patient people.

 

[DaveC426913]

... the tone of some in this thread.
... this level of scorn...
..be treated with disrespect...

I would say the lion's share of posts have been understanding and sympathetic (and, granted, frustrated too). OK, a couple of people took some light-hearted shots at PPM-chasers in general - but scorn, disrespect?

Some PPM-chasers are crazy. Do you suggest we must treat all people with respect regardless of how much they refuse to learn the basics of physics?

Failing to make PPM machines is fun and a good way to learn physics.

Yes, it is. If someone is there to guide these people. The problem with 99% of people who try to make PPMs is that they aren't learning physics; they attempt to defy it.BTW, I see a distinction between the tone about individuals and the tone about a general group of people.

 

[OmCheeto]

And just for the record, I do believe in over-unity.


input electrical energy: 24 watts * 3.5 hours = 0.084 kwh

When in doubt, cheat. Kobayashi Maru!

Sure some are crazy. So are many homeless people. The level of disrespect they get should depend on their ill conduct, not on their lack of technical knowledge.

Yes, it is. If someone is there to guide these people. The problem with 99% of people who try to make PPMs is that they aren't learning physics; they attempt to defy it.

Regardless of their intentions of whether they are just curious or whether they just want to prove somebody else wrong and then show everyone else how smart they are and how dumb everyone else is, I still consider it a good exercise none the less.

Sure a lot of people might say they are 'wasting their time', but if that's what they want to use it on, I say good for them.

Also I'm a little surprised about the comment that the person wouldn't learn physics. I mean after all they are doing experiments aren't they in building these machines? Even if the experiments aren't as controlled as you would find in a university lab, and even if they didn't understand all of the calculus and so on, why would you think that the person wouldn't learn about physics?

I would say that they would learn a hell of a lot about physics don't you think? If they spent that much time and that much effort I absolutely gaurantee that they would learn at least something.

To say the opposite is rather condescending, and suggests a little bit of ignorance. Whether they end up failing or not is irrelevant to the learning issue.

They would learn mechanics, yes, and certainly some physics. But PPMs are all about energy transfer and work. If they did learn the physics involved, they would come to realize why the PPM is flawed in principle, and drop it.

It is the ones who pursue it without cessation who have not learned the relevant physics, and in fact must actively deny it when put in front of them.

i.e. actually learning physics by building PPMs is a negative feedback process. "The more you do it, the more you'll stop."

 

[DragonPetter]

i.e. actually learning physics by building PPMs is a negative feedback process. "The more you do it, the more you'll stop."

Haha. And if the system is just (not) right, it can still act unstable and grow positively, even with negative feedback present. That's when it maybe is a disease :P

But I agree that there is something comendable about PMM designers interest and determination, and "disease" is a bad term for their obsession. Its only when they are actively fooling themselves and others that I disrespect it. I don't mind a person trying to find and design a PMM, I think that's a noble effort. When they have a system and they find the physical reasoning for why it will never be a PMM and still try to fool themselves and others, they are not learning physics and only hurting it.

2. They don't build, much less test their devices.

So all they do is cling violently to whatever misconception got them there.

I gaurantee you're right in that some (perhaps the majority) are this way, but don't paint everybody with the same brush.

If they aren't actually building the devices and testing them, then I wouldn't really say that they are actually doing what they state anyway since working with the "PPM's" or any similar device requires you to come up with some machine whether it works or not, in a physical form. Absolutely agree on that point.

I'm not a physicist by any means just to get it out there, but if someone showed me something that did what they said, and it physically existed, and I could look at it and pull it apart and see that it really did what it did, I would pay attention.

I wouldn't invest in the technology, I wouldn't claim that the guy broke the laws of physics, and I wouldn't even claim that it does exactly what the person says it does in the principles that they say it does but I would still pay enough attention to learn something and to me, this is an important attribute of any scientist.

Nobody is painting everyone with the same brush. The only ones we are painting are the ones that actually get in our faces and won't leave.

By definition, the ones that aren't crazy either

Either way, we are talking about the ones we do encounter, the crazies.

You don't have to invest! You just have to go to the USPTO after watching the amazing HOJO* video and following their instructions to look at the fully patented MAGNETIC PROPULSION SYSTEM!

I looked at the image, and could build a prototype device in about 17 minutes. (nails, neodymium magnets, one matchbox car) Doesn't everyone have those things lying around the house? I do! If you're CRAZY, you can pay the $49.97 for the amazing instructional video. BUT WHY WASTE THAT MONEY! When you can just go to the United States Patent and Trademark Office, and get the whole thing for, can you believe it, FREE!

The other two patents are #4,877,983(issued on halloween. snicker... magnets and a matchbox car again) & #4,151,431(boring! not PM at all... wait... looking at the images. ah! hahahaha!)

[Q_Goest]

There are specific behaviors demonstrated by a small group of people that defies all logic. PMD is very similar to gambling for instance, where the victim has the urge to keep gambling irresponsibly.

We’ve all seen the folks with PMD. They are told exactly why their ideas won’t work and sometimes they even understand, but like a gambler, they go right back at it and do it again and again! That’s PMD. In the gambling world, they call it something else. But it’s real. Ralf doesn’t have it, he understood and accepted the logic but you could see it was starting to get hold of him. I think it’s just as neglectful to not recognize it as some kind of disorder just like gambling.

By the way, OmCheeto posted this and the guy isn’t hard to find. If you look, you’ll also find many others that actually believe in his ideas (not to mention having their own ideas about PM) - and I seriously don’t think they’re simply scammers. They really believe in the validity of PM. They’re providing details of their ideas… and not asking for money! I don’t think any logic or evidence in the world will convince this guy that his idea is wrong, and that is what PMD is.

I almost met one once. In that eX-Filed forum I discussed earlier, someone brought together the fact that pistons of different sizes, under the same pressure, would have different net forces applied. So he proposed sinking his device into the ocean to generate huge amounts of free energy. I looked at his drawing and told him that it would work through one cycle and then stop.

There are specific behaviors demonstrated by a small group of people that defies all logic. PMD is very similar to gambling for instance, where the victim has the urge to keep gambling irresponsibly.

This isn't specific to perpetual motion devices but applies to all invention. The "disease" you describe is nowhere more evident than in the biographies of people like Edison and Tesla, who were addicted to the pursuit of the ground breaking, world changing, invention that would make them rich and famous. The fact they both did invent some remarkable things just made their addiction worse and they both lost much more money pushing their unsuccessful inventions than they ever made with their successful ones. Just like gamblers who win big at the start and keep betting long past the point where their initial winnings are depleted, they both wasted the last half of their lives trying to recreate the success of the first half and failing.

Invention is very much like gold-fever. There's the perception that there are untold fortunes and a place in History to be made with the right invention. A device that produces more energy than it takes to operate is the Holy Grail and also a kind of preliminary filter that catches and holds all the rank morons. It's not a disease unto itself, just a part of the larger fame-and-fortune seeking that lures all inventors, just like the rumor of gold has always lured people into all kinds of hardship and financial calamity.

Please note, there is a selection bias at work here which cause the vast majority of our encounters to be negative:

More eloquent than the way I expressed it.

I'm not a physicist by any means just to get it out there, but if someone showed me something that did what they said, and it physically existed, and I could look at it and pull it apart and see that it really did what it did, I would pay attention.

Re the bolded text: oh definitely, if someone presented me with a PMM that appeared to work, I'd want to get a veeeery close look at it, too. And that's the rub. The PMM people have told me about *don't* exist. I've even had one guy ask me to build a prototype of his idea for him! Lol, yeah right, I'll get right on that...

Inventionitis is a necessary component of PMD, but PMD goes further. The difference is that for Inventionitis, the prospective inventor may or may not realize or be willing to realize that what they are trying to do violates the laws of physics. If they do, they just have Inventionitis. If they don't, they may also have PMD.
