Is it possible that the boxes on the wheel are just full of a Gas that easily changes its temperature, where the top is always a different temperature than the bottom of the wheel? Kind of like how a Stirling engine works with heat or cold. The difference in temperature is what I'm thinking. And the magnets are the decoy .

It’s impressive how efficient they made it. Obviously toy can make the moving parts smaller and slower, or add more energy storage, but that makes the “hide the batteries” part of building a perpetual motion machine harder. I don’t think the “regular maintenance” revealing that it isn’t perpetual is that detracting, especially considering that we already know “perpetual motion” is impossible (in decoherent systems anyways, there might be quantum mechanical phenomena that one would like to call perpetual, but they require very special conditions and aren’t really possible to create (it’s literally impossible to shield a system from neutrinos, for example)).

When I was studying mechanical engineering at Cornell in the late 70s, my thermodynamics prof told a story about a guy who built a boat that appeared to be a perpetual motion machine, confounding all the experts. Later it was discovered that the boat's hull in the saltwater was acting like a giant battery, and the hull was being dissolved.

[@littlegoobie]

galvanic reactions are a huge problem in general for anything around salt water, it's too bad that it doens't generate enough to harness. Iron boats have big blocks of zinc bolted to the bottom to act as the sacrificial anode. I know of one place where the city put up very nice decorative railings around the boat harbors. They're completely made out of heavy welded solid iron, all dip galvanized. If i remember right, galvanizing is supposed to add 30'ish years of protection. These railings and gates are maybe 15 years old now and they're 90% bare iron with minor surface rust. the salt environment is super harsh.

Somewhat difficult to couple the current produced? And if no separation into cells to stack for higher charge, the voltage would just be that of iron, some 1,21 volts. That would not propel a ship. "The redox chemistry of the All-Iron Redox Flow Battery is based on the iron (II) chloride/iron (III) chloride couple at the positive electrode and the iron (II) chloride/metallic iron couple at the negative electrode. During discharge of the battery, iron (III) chloride is reduced to iron (II) chloride at the positive electrode. At the negative electrode, metallic iron is dissolved into the electrolyte as iron (II) chloride; these processes are reversed during battery charging. An aqueous all-iron redox flow rechargeable battery with a nominal cell voltage of 1.21 V and theoretical specific energy of 170 Wh/ kg is a promising low-cost, durable and eco-friendly energy storage system for large-scale applications."

[@tylerhorn3712]

Would it be possible to use magnets to make a machine move back and forth? I'm picturing the same thing, but with big magnets on each side to pull those large blocks up just a bit. It would only swing back and forth. Ideal conditions would be that the magnet can "hold" less than .0001 MG less than the weight the machine puts on it. Though now working through it myself, a bit will be lost to friction with each pass. Unless one was able to 100% convert the heat from friction into movement, it's not possible. One must add an outside energy force or convert literally all change of state energy within a mechanism to power the mechanism.

As long as the magnet draws it back up into its "reset" point on each side, it should go on untill the magnet looses strength (noticeable magnetic degradation takes 5-10 years).

Question is, does it defy some of rules that makes it perpetual motion, we dont know that since it needs to be tested. How i understand perpetual motion machine would be machine that can give more energy that its needed to keep it running. Also, question is, is it based to gravity, if it is- its useless lets say in space station to generate free power. They could do this just to get media attention this is one posibility too. At the end, we already have free generating machines, at dams and rivers that use flowing water, unlike solar power river flows constantly and gives electricity, and that in my book is good enough, of course machines need maintance from time to time, but if you make it less robust and simple, it would give much more energy that is cost of machinery

The giant Dreadco box is super suspicious. It's also in the center of the wheel. Likely it contains something like a motor and batteries. Notice the screws on the front, which look like they have a little wear (2:30 - 3:00). Once the wheel is spinning it wouldn't take much force to overcome friction and keep it running. The other clue is the secret is disappointing. So this rules out being driven by changes in air pressure or temperature. Solar is unlikely as well, given they keep it in the dark. It's something simple like a battery or spring. As they also noted it slows down over time.

[@NonEuclideanTacoCannon]

It doesn't take much to keep a bike wheel moving, especially that slowly. I'm almost certain that the boxes mounted on the wheel are magnets, and the things the boxes move through are electromagnets. The smaller disc in the center has magnets around the edge, and the probes have a hall effect sensor for timing. When the magnet crosses the hall effect sensor, it supplies a small current to the electromagnet to pull the magnet in, then the second hall effect sensor reverses the polarity to push the magnet back out the other side. I bet a 9 volt battery could keep such a thing going for a year or more.

[@bigtime39384]

that's my guess too.

[@JanCiger]

Probably not a Hall effect sensor. Those are pretty power hungry devices, esp. if we are talking about ones from the early 80s when this was apparently made. It is very likely there is no fancy electronics in there at all. Something like a reed relay would do the same job with no power required.

[@edwardsmallwood1201]

I mean, honestly, I’ve got clocks that run longer than 2 years on a AA battery…

[@edwardsmallwood1201]

Technically, perpetual motion exists on a geological time scale. We call it planetary motion, and it’s quite useful for sending space probes around and out of the solar system. A nice little machine that creates useful perpetual motion? You’re going to have to prove that to me.

[@anthonyx916]

The sensor would be the driving coil itself - as a box containing a coil ("electromagnet") passes the fixed magnets, a small voltage/current will be induced which the circuitry can detect and use to trigger a pulse in that coil to produce the kick.

[@DevilMaster]

Okay, I think I got it. At its heart, it's an electrical engine, only, there's a lot of misdirection involved. First, the three boxes conceal batteries, connected in series, with wires hidden within the wheel. They power the stator, which lies in the wheel hub, while the spindle that is fixed to the external frame contains the rotor. The metal bars of the frame are used to make the rotor heavier than the stator, so the stator (the wheel) rotates instead. The copper pipe, the heatsinked box and the labelled box contain additional weights. The pipes are made out of copper, and connected to a box with a heat sink, to suggest heat exchange, but that is misdirection. The light detectors on the sides of the labelled box only exist to suggest solar power, but they might even not be connected to anything. More misdirection. And finally, those metal structures on the left and right of the box are made to look like magnets, they might even be magnets to fool someone with a magnetic field detector, but they are only there as... you guessed it. Misdirection.

[@evanislost]

I was thinking that the box in the middle housed a thermoelectric generator, and the movement of everything inside the plexiglass generated heat, while the museum is probably cold, and everything is insulated really well. The energy generated gets transferred to the motor in the middle of the wheel somehow. Could the box with the heat sinks and copper pipes be somehow directing heat towards the generator as well?

In the cartoon that came with the original presentation, he actually says that the metal frame is meant to be misdirection ... but that's just what someone who needed a metal frame would say.

I'm 95% sure it's electrostatic. The boxes and the "U"s aren't magnetic. There's another video where they test it with a magnetometer. Note the pointy electrode, and the series of cups. It's an inverted wimshurst machine. Normally you turn it to generate electric potential and big sparks. But if you do it backwards and apply a high voltage, it'll spin. The fun thing is, it takes a ridiculously tiny amount of energy to move electrostatic motors. Which makes it perfect for something that needs to run for ages. Big chunky battery in the box, and something to hold a charge, and step up the voltage. Some sort of joule thief thingy to make sure it keeps on chooching, and a super well balanced wheel. Tiny electric field keeps the wheel going until the system runs out. The boxes are there so he can easily balance the wheel. 3 points is the number of weights needed to balance a wheel without needing to carefully find the exact point to put weights. Either everything else is a decoy, or he snuck some sort of passive energy harvesting mechanism to help keep the thing charged, but I doubt it if it needs to be "serviced". Serviced means recharged.

Have you noticed that the heat sink uses ni wire but instead uses two copper tubes ? That means its power is coming from a gas. I would bet the gas is a refrigerant which would explain the heat sink being as an evaporator coil. It's turning because when the gas cools and heats in a cycle it causes an unseen rotation of invisible gas which causes the wheel to turn. So why two years. ? Most R 12 family refrigerants wont last two years in such a small amount. Why ? The gas leaks out of tiny microscopic holes in Pipes, Glass or Plexi causing it to slow down or stop.

[@nazgullinux6601]

Its an electrostatic motor that is powered by a clever wimshurst generator which uses the inertial momentum and the imbalanced 2 vs 3 configuration to constantly produce an emf. One U-shaped device on one side is wimshurst cathode, one is anode. The 3 squares out 120 degrees apart are very carefully folded copper foil conductors in such a geometry that it has the most possible surface area. The charge is stored in very low farad rating capacitors which collect charge to produce the high voltage. A very simple machine. Can't possibly drive a load. And, as she stated, it does slow down. Which means its extreme efficiency and not even close to perpetual motion.

[@1FreeSelfGoverningAmericanMan]

Here is how it works Adam. Every time one of the 3 black boxes goes through one of the 2 permanent magnets, a magnetic reed switch in the black box closes a circuit with a coil and a long life battery also contained within the black box, perhaps a silver battery, thus creating a weak magnetic field with polarity oriented such that it repels away from the permanent magnet. This happens every 60 degrees of rotation of the wheel with each pulse imparting just enough energy to keep the wheel turning. The periodic servicing is to replace the batteries.

[@alangreen5858]

My thoughts too. If you could accurately measure the angular velocity of the wheel during a full revolution I suspect you would see 6 small increases little 'kicks' if you like. Each one corresponding to the passage of the boxes past the two permanent magnets. The rest of the apparatus is probably just a decoy. I don't know if anyone could use a video of the wheel to do accurate enough velocity measurements to confirm? Probably not.

And it is this balanced look at the equation to why a real perpetual motion machine does not exist: A machine that uses an incredibly small amount of energy input, over an incredibly long period, With very low resistance will do an equally incredibly tiny amount of work. Adjust any of these four variables and you can alter the amount of work output, time, resistance or energy input. But it must balance out.

It could be a combination of things, the 'weights' (if they are weights) acting as a flywheel, the Dreadco box containing a battery, imparting a small magnetic repulsion, the light sensors to maintain the charge, and perhaps those copper pipes and box are to disguise a valve on the underside to pull a vaccume in the enclosure, reducing drag.

[@nathanroberson]

It’s not in a vacuum. The spokes have a lot of resistance from running through the atmosphere gas. Even a spinning top cannot spin past 20-30 minutes that has more precision than this wheel can achieve. For sure it is using electromagnetic forces that are greater than the frictional drag

[@Reptex_cs]

No chance it would spin for even a week, no chance at all

[@ulicadluga]

What's really baffling is that it is possible to build a machine that, to all intents and purposes, behaves like a "perpetual motion machine". If we have tides on earth - tides that have been ebbing and flowing for billions of years, then a machine can be built that is "wound" by tidal forces. "Perpetual Motion" is defined as requiring no external impetus or force and not having any friction. With the mere existence of "friction" or "tidal locking", a "perpetual motion machine" is impossible. Any system that disperses energy, even the Universe is, by definition, not a "perpetual motion system".

I remember when David Jones first built this. There was a television program where he talked about it, so somewhere there's footage of the creator giving additional info on the device including a couple of yesses and noes to ideas as to how it works. I think it originally went on display at an expo in Germany for some reason and must have then ended up with Sir Martyn Poliakof. Very pleased to see it's now in the Royal Society's caring hands.

[@TapTapClick]

David Jones gave the machine to Sir Martyn Poliakof in his will but Sir Martyn knew he was going to get it and asked for him to write how it works so that he could get it working again when/if it stops working. Also the show where he talks about it the most he says is "I produced a machine which of course obeys the laws of physics, It get's it's power from somewhere, I'm not saying where. It turns it into wheel rotation some how, I'm not saying how."

[@jakeeasterwood3204]

I think it powers itself off of the energy produced by people bending over and looking around inside trying to figure out how it keeps running. As long as there are people bending over looking in it… it will keep running. If there is no one… it will eventually stop. A really good question would be… “Does it really spin when there is no one to see it?”.

[@Papa_0urs]

Erwin Schrödinger did answer that question long ago ;o)

[@getoffmyinternet]

More of an “if a tree falls” thing

[@SF-fb6lv]

That's actually a good idea; maybe have a piezoelectric generator hidden under the surrounding 'base' of the stand that the machine is sitting on. As people walk up to inspect they inadverdently power it.

[@moenunley3108]

That would actually be highly impressive. Not underwhelming at all

[@ninesixteengenetix]

[@gutz1981]

How is it "Perpetual" if it takes about 2 years before it needs resetting? If this thing has some self contained internal/external power source, then it is no different than a analog clock that needs a battery change every 2 years or so as well.

[@BoondockMercantile]

Watching Adam's mind work is just a treat. The "light bulb" moments working with the "gear-turning" moments is fun.

[@Prism775]

These kind of devices are interesting because it’s almost like watching someone solve a problem when they are giving the designer more credit than may be owed and offer solutions that are somewhat overly complicated. If you asked Adam to make this as a prop for a film I think he would have given very different solutions. This very much looks like some type of belt is running around or within the wheel through the copper tubing and is likely being driven within that box that looks like it has too much going on.

[@nicazer]

@@Prism775 I think adam is onto something with the magnets creating a split apart motor. the belt idea introduces a lot of movement and friction to the system, so much so that I wouldn't expect it to run for a couple years without needing new batteries. Adam's idea of the energy being electrical to magnetic introduces very little loss, which could explain the longevity of the spin, and is also dead silent.

[@disliked1390]

He reverse engineered it quick. It's for sure 1 or 2 batteries hidden somewhere giving some sort of power for a few milliseconds to make magnets turn it.

[@christopherrenn8137]

It's very rare that we see Adam truly giddy at an Idea. He nearly jumped out of his skin when she said, "Send us your notes/contributions and we will add them to our archive..." (paraphrasing ofc). The idea of him being in the The Royal Society's archives in anyway lit a fire under him :D.

[@Fribee83]

I just kept looking at her face the whole time as Adam is verbally deconstructing the device with such joy. "Only two people know the secret to how it works" "What you just said is a clue and I figured it out" It's like watching Penn and Teller Fool Us being challenged.

[@ericp3645]

The entire framework is made of 1 inch square tube. It could contain dozens of battery cells.

[@ronindebeatrice]

I think it would be decidedly heavier if that were so; nobody in the Society would question how it worked if it weighed as much as 100 cells.

If u think it's batteries .... make one and see how long it last. I bet u only get 4 months rotary motion before the batteries die, giving the volume of the hidden areas.

[@AdmiralQuality]

@@piercebishop4052 You fund the project and sure! As Eric already pointed out, all that frame tubing could contain batteries, as well as the copper tube and the heat sink box thingie. The wheel hub has lots of space too. Put that wheel on a couple of pinpoint ruby bearings, evacuate most of the air from it, and it's near frictionless.

[@raymorgan4657]

A while back I made a wooden gear pendulum clock that is electrically powered, but takes very little electricity to run (think servicing every two years of this machine). The way the clock keeps running is that in the base is a dual electromagnetic coil, and a transistor for switching. In the bottom of the wooden pendulum is a permanent neodymium magnet. As the magnet passes over the outer dual coil, it picks up enough of a slight charge from the moving magnet passing over a coil to allow the transistor to briefly switch on the inner battery powered coil which is wrapped around an iron nail. This very briefly creates an electromagnet opposite polarity of the magnet in the pendulum that repels the magnet in the pendulum and gives it just enough of a little push to keep it swinging. The cycle repeats each time the pendulum passes over the coil hidden in the wood base, which keeps it swinging back and forth. Now my clock, is not an impossible perpetual motion machine, it's just a clock, however, it demonstrates how easily something can be hidden and keep something moving for a long time with very little power.

[@Виталий_Петров_Н]

Почему не вечный двигатель. Вы сделали параметрический маятник, который не нуждается в дополнительной энергии, акромя энергии небольшойй батареи.. Если его масштабировать, то можно построить мощный в несколько кватт генератор энергии. Для дома или квартиры в самый раз. А можно воспользоваться идеями Джона Бедини. И вместо небольшой катушки намотать большую для создания магнитного импульса и маленькую для подачи сигнала на базу транзистора. И поставить аккумулятор на 9-12 вольт.

[@raymorgan4657]

@@Виталий_Петров_Н Because you can never get out more energy than put in. With the pendulum, it still using battery energy that will run out. As soon as you tried to use the output of the pendulum to power something, in my case the clock, it needs energy to keep going that will run out.
