Methods for achieving a appearance of incessant suit have been published in many places. I’ve brought some of them together here to uncover that it isn’t tough to mistreat those who wish to trust in incessant motion. This can assistance teach people to skeptically demeanour for evidences of such deception.
Revolving Shaft Without Power.
This device outline is from a book The child automechanic : book 2: 1000 things for boys to do. (c1915). Handicraft Publisher: Chicago : Popular Mechanics Press. Also accessible in a reprint edition.
The device illustrated seems enigmatic for it apparently works though any appetite being unsentimental to it, creation from dual to 3 revolutions per hour, which, nonetheless slow, is though motion, requiring energy.
The missile A is upheld on a edges, in a march B and C, of a tank, D. A disk, E, carrying a executive hole incomparable in hole than a shaft, is located during a core of a latter. The hoop is upheld by 12 or some-more string ropes, F. The tank is filled to a spin G with water. The reduce ropes, being enthralled in a water, cringe and lift a hoop somewhat above a core in a position of an eccentric, as shown by a dotted lines in a sketch. The core of sobriety of a hoop in this position, being aloft and somewhat to one side of a shaft, a hoop has a bent to spin around. The suit drives a subsequent wire into a H2O where it becomes dripping and decline takes place again, lifting a hoop to a aloft position, while a wire entrance out of a H2O dries out. The ropes rising from a H2O though not nonetheless entirely dry means a tip partial of a hoop to be in an individualist position aside with anxiety to a core of a shaft, so causing a core of sobriety to be not customarily above though also somewhat to one side. – Contributed by Charles Roberts, Brooklyn, N. Y.
I haven’t built one of these yet. But if any of we child mechanics reading this have built one, I’d like to hear about your results. You need ropes that cringe when wet. But soppy ropes are heavier than dry ones, so we need to change things carefully. The source suggests 12 or some-more ropes. Not too many more, for if there are too many, a wetting of customarily a few of them won’t change a disk’s core of sobriety much.
Rubber Band Heat Engine.
Rubber rope feverishness engine.
A easier device is infrequently seen in production deartment arrangement cases, to bewilder undergraduates. A lightweight steel circle edge has many spokes, finished of rubber bands, trustworthy to a low attrition hub. In a straight march a circle turns slowly. But there’s a pretence stealing in plain sight. An illuminated flare illuminates a circle from one side. The feverishness from it creates a rubber bands on that side somewhat warmer, so they agreement in length. Yes, rubber acts that approach and we can find out since here. This shifts a circle edge off-center creation a circle ceaselessly heavier on one side. Of course, if that light is incited off during night, a circle stops turning.
See Haverford production demos. from that a design was taken. In a design a flare is too apparently partial of a complement (and a source of energy). The dishonesty works best if a whole thing is in a potion arrangement box and a flare is positioned to seem as if a purpose was customarily to let we see a circle in improved light.
All of a ideas in this territory are feign incessant motion. They are not dictated to denote over-unity performance. They simply run for a prolonged time though mitigation of speed, and do no useful work. They work since they are low attrition and low mass and do not need many appetite to means their motion.
Perpetual suit clocks.
Clever clockmakers have prolonged been building newness clocks that impersonate apparent incessant suit appurtenance designs. Their purpose is to make a time seem to be powered by a incessant suit resource clearly in view. But a genuine appetite that keeps a resource going is hidden, customarily a customary wound open or a carried weight with a circuitous mechansim deftly hidden.
One of these recently flush on YouTube, claiming to be incessant motion. It is customarily a facsimile of a “Ignatz” or “The Flying Pendulum Clock” invented and law (286,531) in 1883 by Adler Christian Clausen and J. C. Slafter. See Flying Pendulum Clock. It has a “tetherball” escapement prominently mounted on top, providing visible interest. You can see a outline and design of it during Pieces-n-time.com.
Though a apparent describes it as an “improved” time regulator, it indeed regulates a time unequivocally poorly. But it is fun to watch.
Model of a Congreve Clock
ModelWorks International Ltd.
Sir William Congreve designed a time regulated by a steel round rolling on a zig-zag lane on a vast slanted prosaic plate. When it finished a route, a image was triggered to lean in a other instruction and a movement repeated. This was patented, and even currently hobbyist modelmakers like to build replicas of this clock. The pushing open was secluded within a drum trustworthy to a vast gear. So some people suspicion that a round was pushing a clock. But it was customarily controlling a clock. Regulating it rather poorly, actually. You competence remember that Congreve is a chairman obliged for that sequence of sponges incessant suit appurtenance idea.
Other methods are used by time and watchmakers to make mechanisms that “never need winding”. These embody wristwatches whose springs are wound by a suit of a wrist, clocks powered by changes in windy pressure, and those powered by ambient feverishness changes.

Radium Perpetual Motion
Physicist R. J. Strutt (1842-1919) built a radium electroscope in 1903. It continued a suit for an impossibly prolonged time. An evacuated quartz potion tuber contained an middle potion block with a tiny volume of prohibited radium. The nucleus glimmer from a radium (A) charged a gold-leaf leaves (C) that solemnly changed detached until they overwhelmed a steel foil on a inside of a cover and discharged. Then a charging and discharging cycle started over again. This routine was singular by a spoil life of a radium isotopes, that means that a charging gradually decreased over time. A unequivocally prolonged time. The half-life of a isotope Radium-226 is 1601 years. Then a charging rate would be customarily half what it was initially, though a movement would still continue.
One of a simplest deceptions is to censor batteries in a device itself.
A elementary wheel, even a vast one, with high peculiarity dry bearings, requires unequivocally tiny appetite to means a motion. Imagine, for example, a bicycle wheel. Now cruise how many batteries could be dark inside a rubber tire. Quite a few; adequate to appetite a circle for several years. Of march you’d wish to use batteries with a prolonged shelf life. Museum displays of such machines are customarily in place for during slightest a year. Some years ago mercury batteries would have been a best choice, though currently lithium batteries would be preferable. A tiny electric engine could be dark within a wheel’s hub, and a electrical appetite conducted by a wheel’s spokes, one of them subtly insulated during any end. Just an suspicion we competence wish to try.
Another “in plain sight” process is to put batteries inside a steel cylindrical bombard that plays a purpose of a relocating weight. People don’t design batteries to be stealing in relocating parts. Batteries can be performed in prosaic piece form, like those used in present detailed film packs that appetite a camera’s flash. The stealing places are singular customarily by your ingenuity.
In 1774 astronomer and automechanic James Ferguson saw and described a barometric time shown here. It had a vast mercury barometer with 150 kg of mercury in dual potion vessels, one with a mouth in a other. Linkages and an inventive resource during a tip responded to changes in mercury level, branch a circle and ratchet that wound a open that arguable a clock’s motion. Similar, though smaller, clocks driven by windy vigour changes are still finished today.
The same arrange of ratchet circle circuitous intrigue can also be driven by thermal enlargement and contraction of steel rods. Yakov Perelman in his 1913 book Physics as Entertainment describes such a time regulating a thermal enlargement and contraction of potion glycerin. The time was tested and ran for a year though attention. Glycerin stays potion from 30°C to 290°C so it is ideal even for outside clocks. Only a 2°C fluctuation of feverishness is adequate to means a clock’s operation.
Ratchet circuitous mechanism
of thermal enlargement device.
This thermal powered device is described in Perelman’s book (Fig. 77, p. 113). It has a ratchet resource powered by thermal contraction of steel rods Z1 and Z2 as they cool. The ratchet Y turns as Z2 contracts and ratchet X turns as Z1 contracts. This solemnly turns a circle W1 during a right that is a “bucket” circle that rises mercury from a fountainhead R1 during a bottom to a fountainhead R2 during a top. From there a mercury drips onto a circle W2 during a left, branch it, and also a pulley K1 pushing belt K that runs adult to expostulate pulley K2 and afterwards something else unspecified. The mercury seems nonessential when a elementary open would do. This looks unequivocally many as if it were designed essentially for visible seductiveness and deception.
The Crookes Radiometer.
The Crookes Radiometer (sometimes called a “Light Mill”)
was invented in 1873 by Sir. William Crookes, and is still accessible from scholarship fondle stores. It consists of an evacutated potion tuber with vanes inside offset on a needle point. The vanes (usually four) are blackened on one side, silvered on a other. In object they spin fast and continually. Even with a 100 watt illuminated tuber a few feet divided they spin slowly.
Some textbooks used to explain this by observant that a light photons were engrossed by a black side, though reflected from a silvered side, and therefore they gave larger movement to a vane when distinguished a silvered side. That sounds good, though a tangible device turns in a “wrong” direction.
These toys do not have a ideal vacuum. There’s residual atmosphere inside, and a molecules attack a vanes gives a vanes larger movement than that of photons simply resilient from a silvered surfaces. The Crookes radiometer is therefore a feverishness engine.
When light falls on a black vanes it is engrossed and a feverishness of a black side rises. Light descending on a glossy side reflects and imparts unequivocally tiny appetite to a glossy side of a vane. Therefore a black side has aloft feverishness than a glossy side, and a potion tuber is cooler that presumably of them. The black and glossy sides contingency be thermally insulated from any other to contend a feverishness difference, though a black and white paint itself can yield sufficient insulation.
So when molecules strike a black vanes and rebound, they benefit appetite from a vane and miscarry with increasing speed. When they strike a glossy side (which is cooler) they benefit reduction appetite from a vane, and benefit reduction speed. The movement change of a molecules bouncing from a black side is larger than when they rebound from a glossy side, and therefore a vane rotates with a glossy side of a vanes in a brazen direction. The molecules are slowed when they strike a cooler potion bulb. This molecular dynamics has larger outcome on a vanes than a photon movement mechanism. The examination has been finished in circuitously ideal vacuum, and afterwards a photon movement indication is confirmed. But a radiometer toys we can buy have unlawful vacuua and are dominated by molecular kinematics.
Use of solar cells competence seem an apparent choice for a incessant suit deception. But it’s tough to costume these cells, and a diversion would be given divided by simply covering a whole appurtenance with a black cloth, or branch out a room lights. This is not a unequivocally unsentimental process for false purposes. Better to appetite your feign PMM with something reduction simply detectedsomething invisible.
We are surrounded by electromagnetic deviation from radio and radio stations. A museum arrangement device can be sized to act as an receiver for internal deviation of this type, converting it to DC appetite to expostulate a device. The conversision resource can be simply dark in a appurtenance tools themselves. The downside is that during vast appetite outages in a city, a internal promote stations competence go off a atmosphere and your appurtenance would delayed to a stop. So a backup appetite source would still be indispensable if a appurtenance were in a open setting, like a museum. Why not set adult your possess broadcasting hire in a circuitously room, with battery backup power? Some doubter competence come along with an electromagnetic deviation detector and display a deception. And a Federal Communications Commission competence go after we for bootleg broadcasting. Best to use a naturally existent environmental appetite source.
In any room there are convection atmosphere currents, though these are frequency arguable adequate in strength and instruction for dishonesty in a open environment where people pierce about a room. Museum PMM deceptions are customarily housed in a potion or transparent cosmetic box towering on 4 slim legs to remonstrate people there’s zero connected to a appurtenance inside. It also keeps people’s hands from touching a relocating parts. Those legs contingency be stout enouough to keep a box from relocating and contingency be apparently solid, not hollow. But how can a viewers tell presumably a legs are hollow? Even skinny rods can be hollow. If a ancillary legs were finished of transparent potion or lucite they could still be vale and no one could tell. They would make excellent pipes to communicate relocating atmosphere into a cupboard from a dense atmosphere source underneath a floor. we can suppose dual such vale pipes forcing atmosphere into a cupboard and dual on a other side behaving to lift atmosphere from it, environment adult a crafty atmosphere dissemination in a cabinet, invisible to onlookers. A indication windmill inside could be driven by a air, and in spin pushing a vast wheel, while onlookers competence consider a circle was pushing a windmill. Downside: Moving atmosphere customarily creates noise.
Just a crazy idea, we say? Well a dark source of dense atmosphere was one of a methods of dishonesty used by John Worrell Keely to keep his incessant suit scams going during a 30 years he successfully hoodwinked investors in his Keely Motor Company.
Top Secret spinner toy.
Roger Wayne Andrews performed in 1974 Patent #3783550 for a “Novelty Electric Motor”. This apparent lonesome a accumulation of toys that postulated suit for days with no apparent source of energy. They all had dark batteries (usualy 9 volt) connected to a transistor and a tapped electromagnet coil. The initial one marketed was called Top Mystery finished by a Andrews Mfg. Company and sole by a Johnson Smith Company (of Whoopie Cushion fame). It consisted of a elementary cosmetic bottom on that a tiny tip (22) was set spinning on a concave surface. The tip enclosed a dark permanent magnet and an electromagnet was dark in a base. As spinning tops will, it wandered around a somewhat concave surface, though when it got circuitously a core (lowest point) a magnet was tighten adequate to a electromagnet’s curl (16) to satisfy a stream in it, and a apportionment of this tapped curl granted a intensity to a bottom of a transister (20), vast adequate to trigger a transistor into a “on” state, permitting a battery (18) to send stream by a whole coil. Its captivating margin gave a spinning magnet a slight boost, frequency noticable. The transistor acts as an electronic switch. To serve mislead observers, a tiny strike (12′) in a concave aspect causes a spinner to be deflected toward a outdoor edge of a device. The ensuing spinner trail could be utterly formidable and clearly unpredictable.
Various forms of a Andrews toys.
A uninformed 9 volt battery would means continual operation for adult to 7 days. For occasional use a battery would final some-more than 6 months (or a shelf life).
Underside of Andrews spinner. The transistor is during a bottom of a coil.
This fondle is still marketed currently underneath a name Top Secret and costs about $10. Many variations regulating this same “secret” appetite source are seen in fondle and newness stores, finished in Japan or China. The transistor-coil public could be private and blending to other false uses, and we consider that it, or something many like it, is a belligerent appetite behind some claimed incessant suit machines seen on U-tube.
None of these toys need an on/off switch. When a relocating magnet is removed, a transistor is in a “off” state, and no appetite is drawn from a battery. Generally a coil, transistor and battery are dark underneath a felt pad on a bottom of a base, that can be pried adult to put in a uninformed battery. When used occasionally, a battery lasts scarcely as prolonged as a shelf life.
Another chronicle had a spinner on concave rails. The element was a same. Another apparent focus described in a apparent had a same triggered curl underneath a pendulum. This is suggestive of other inclination experimenters used to build even before transistors were invented. They had a integrate of automatic captivating reed switches to spin a electromagnet on and off, all hidden, along with a battery, underneath a list or in a bottom of a pendulum.
I’m certain we can consider of ways this simple element could be unsentimental to many other feign incessant suit designs.
The Hammel spinner and associated inclination are all over a internet these days . Those that work have a common underline of a magnet hold in a palm circuitously a spinning hoop or circle that has permanent magnets. Videos uncover a circle turning, presumably forever, or until we get sleepy of holding a magnet.
Where does a appetite come from? From a palm holding a magnet, by a idemotor effect. See Why Won’t My Perpetual Motion Machine Work? Always be questionable of any claimed PMM device that customarily works when someone binds a magnet circuitously it.
One of a initial inclination of this arrange was Howard Johnson’s captivating motor, that was law in 1979.
Other videos on a web uncover identical inclination though with a superficial magnet fixed in place, or mechanically related to a suit of a wheel. These are faked.
Paper spinner trick.
Another proof of this arrange is an aged celebration trick. A lightweight hankie paper is easily folded and offset on a indicate of a pin. When a person’s palm is brought near, a paper can start rotating, due to a convection atmosphere currents circuitously a comfortable hand.
Power in plain sight.
Here’s a crafty device described by Yakov Perelman in his Physics for Entertanment.
I consider a cleverest “perpetual motion” appurtenance ever invented was one displayed during a Paris Exposition in a 1860’s It consisted of a vast circle with balls rolling about in a compartments. The contriver claimed that nobody would ever be means to stop a wheel. Many visitors attempted to stop it though it went on branch as shortly as they took their hands off it. Not a singular chairman satisfied that a circle incited precisely since of a bid he finished to stop it. The behind pull he gave to stop it wound adult a open of an artfully secluded mechanism.
Of march a circle indispensable a dark source of appetite to get it going, substantially that open was wound in allege of a demonstration.
Here’s an practice for a reader. One of a classical cases in a story of feign incessant suit inclination is that of Johann Bessler (a.k.a. Orffyreus) who demonstrated (in a early 1700s) a vast circle that could lift weights, run a timber saw and do other kinds of work. Later versions of this circle had a ability of handling in presumably direction, and if given a tiny pull in presumably instruction would benefit speed afterwards settle in to a consistent speed dynamic by dual vast pendula trustworthy to it (which expected acted as speed governors). One considerable underline was that a circle could lift someone off a belligerent if he attempted to move a circle to a stop. See Johann Bessler.
The story is full of clues to how such deceptions could be accomplished.
Could these dual wheels have something in common? we consider it possible, and am astounded that this pretence has not been used some-more recently for proof purposes. Get a appetite (or during slightest partial of it) from a unequivocally processes that seem to be display that a circle is producing power. This is functionally like a appetite liberation braking complement in hybrid automobiles, regulating a appetite that would differently be squandered in required attrition braking to assign a batteries instead.
Here’s an practice for readers. Build a device that gets a nutritious appetite from attempts to try to stop it from turning. It needn’t be as vast as these dual were. (The largest Bessler wheels were 12 feet in diameter.)
Feedback. The simplest giveaway appetite device.
The figure illustrates an aged fun creation fun of incessant suit ideas that feed behind a outlay of a device to appetite a input. Even a many genuine incessant motionist recognizes a stupidity of this idea, and wouldn’t even be tempted to try it.
But what if we could, by deception, spin this fun into a feign device that would seem to furnish appetite from nothing? It has been done. See:
So how was this pretence done? Unless a contriver reveals his method, we can’t be certain, though customarily from a videos we can use a believe of electricity to digest a approach to transcribe a effect. Once we “get it” we unequivocally conclude a artistry of a contriver who finished this device, and his ability in dishonesty when creation this video. I’m reminded of a gifted theatre wizard executing a flawless illusion. And he knew his physics, too.
I was tempted to explain how to do it in this document. In fact we even had a content written. But on second thought, we resisted. I’ve seen how many people on a internet feign to know physics, though are deceiving themselves. One of them competence “try this during home” and disaster it up, with presumably inauspicious consequences, and we competence feel some responsibility. Now we know that identical electrical tricks have been used safely for over a century in production harangue demonstrations. But in this complicated society, with inspired lawyers prowling for prey, one has to be careful. I’ve prolonged felt that fools merit a consequences of their foolishness. Like towering climbers, folks who travel on prohibited coals, travel opposite Niagara Falls on a tightrope, or people who wish to detour a universe solo in a rowboat. All of these can be done, though they lift significanat risk. Also, they can have critical consequences for others.
Some of a ways that electrical tricks of this arrange can be finished need homebuilt inclination that block into a domicile electrical system, and these inclination are not authorized by a Underwriter’s Laboratory. They would violate a electrical codes of many communities. A residence glow could outcome from inadequate construction of a device, and if a means were discovered, glow word would substantially not cover it. There is zero so foolproof that some dope can’t disaster it up.
For some-more examples of counsel incessant suit appurtenance deceptions see Unworkable Devices as Fine Art.
There seems to be a abounding lodge attention of hobbyists creation feign incessant suit inclination and posting videos on a internet. Some unequivocally easily finished calculated models of clasic incessant suit device proposals can be found here: Perpetual Motion Machines (Hypothetical). There’s a disclaimer, “Not to trick, though to inspire” during a tip left of a initial pretension screen.
