Fake perpetual motion machines you can build.

Then the charging and discharging cycle started over again. This process was limited by the decay life of the radium isotopes, which means that the charging gradually decreased over time. A very long time. The half-life of the isotope Radium is years. Then the charging rate would be only half what it was initially, but the action would still continue. One of the simplest deceptions is to hide batteries in the device itself. A simple wheel, even a large one, with high quality dry bearings, requires very little power to sustain its motion. Imagine, for example, a bicycle wheel. Now consider how many batteries could be hidden inside the rubber tire.

Quite a few; enough to power the wheel for several years. Of course you'd want to use batteries with a long shelf life. Museum displays of such machines are usually in place for at least a year. Some years ago mercury batteries would have been the best choice, but today lithium batteries would be preferable. A small electric motor could be hidden within the wheel's hub, and its electrical power conducted through the wheel's spokes, one of them subtly insulated at each end. Just an idea you might want to try. Another "in plain sight" method is to put batteries inside a metal cylindrical shell that plays the role of a moving weight.

People don't expect batteries to be hiding in moving parts. Batteries can be obtained in flat sheet form, like those used in instant photographic film packs that power the camera's flash. The hiding places are limited only by your ingenuity. Atmospheric Clocks In astronomer and mechanic James Ferguson saw and described the barometric clock shown here. It had a large mercury barometer with kg of mercury in two glass vessels, one with its mouth in the other. Linkages and an ingenious mechanism at the top responded to changes in mercury level, turning a wheel and ratchet that wound the spring that maintained the clock's motion.

Similar, but smaller, clocks driven by atmospheric pressure changes are still made today. Thermal Clocks The same sort of ratchet wheel winding scheme can also be driven by thermal expansion and contraction of metal rods. Yakov Perelman in his book Physics as Entertainment describes such a clock using the thermal expansion and contraction of liquid glycerin. The clock was tested and ran for a year without attention. Ratchet winding mechanism of thermal expansion device. This thermal powered device is described in Perelman's book Fig. It has a ratchet mechanism powered by thermal contraction of metal rods Z 1 and Z 2 as they cool.

The ratchet Y turns as Z 2 contracts and ratchet X turns as Z 1 contracts. This slowly turns the wheel W 1 at the right which is a "bucket" wheel that lifts mercury from the reservoir R 1 at the bottom to the reservoir R 2 at the top.

From there the mercury drips onto the wheel W 2 at the left, turning it, and also the pulley K 1 driving belt K that runs up to drive pulley K 2 and then something else unspecified. The mercury seems unnecessary when a simple spring would do. This looks very much as if it were designed primarily for visual interest and deception. Solar Power The Crookes Radiometer. William Crookes, and is still available from science toy stores.

It consists of an evacutated glass bulb with vanes inside balanced on a needle point. The vanes usually four are blackened on one side, silvered on the other. In sunlight they turn rapidly and continually. Even with a watt incandescent bulb a few feet away they turn slowly. Some textbooks used to explain this by saying that the light photons were absorbed by the black side, but reflected from the silvered side, and therefore they gave greater momentum to the vane when striking the silvered side.

That sounds good, but the actual device turns in the "wrong" direction.

Classic Fakery Methods.

These toys do not have a perfect vacuum. There's residual air inside, and the molecules hitting the vanes gives the vanes greater momentum than that of photons simply rebounding from the silvered surfaces. The Crookes radiometer is therefore a heat engine. When light falls on the black vanes it is absorbed and the temperature of the black side rises.

Light falling on the shiny side reflects and imparts very little energy to the shiny side of the vane. Therefore the black side has higher temperature than the shiny side, and the glass bulb is cooler that either of them.

The black and shiny sides must be thermally insulated from each other to maintain the temperature difference, but the black and white paint itself can provide sufficient insulation. So when molecules strike the black vanes and rebound, they gain energy from the vane and rebound with increased speed. When they strike the shiny side which is cooler they gain less energy from the vane, and gain less speed.

The momentum change of the molecules bouncing from the black side is greater than when they bounce from the shiny side, and therefore the vane rotates with the shiny side of the vanes in the forward direction. The molecules are slowed when they strike the cooler glass bulb. This molecular dynamics has greater effect on the vanes than the photon momentum mechanism. The experiment has been done in near perfect vacuum, and then the photon momentum model is confirmed.

But the radiometer toys you can buy have imperfect vacuua and are dominated by molecular kinematics. Use of solar cells might seem an obvious choice for a perpetual motion deception. But it's hard to disguise these cells, and the game would be given away by simply covering the whole machine with a black cloth, or turning out the room lights. This is not a very practical method for deceptive purposes.

We are surrounded by electromagnetic radiation from radio and television stations. A museum display device can be sized to act as an antenna for local radiation of this type, converting it to DC power to drive the device. The conversision mechanism can be easily hidden in the machine parts themselves. The downside is that during massive power outages in a city, the local broadcast stations may go off the air and your machine would slow to a stop.

So a backup power source would still be needed if the machine were in a public setting, like a museum. Why not set up your own broadcasting station in a nearby room, with battery backup power? Some skeptic might come along with an electromagnetic radiation detector and expose the deception. And the Federal Communications Commission might go after you for illegal broadcasting. Best to use a naturally existing environmental power source. In any room there are convection air currents, but these are hardly reliable enough in strength and direction for deception in a public setting where people move about the room.

Museum PMM deceptions are usually housed in a glass or clear plastic case elevated on four slender legs to convince people there's nothing connected to the machine inside. It also keeps people's hands from touching the moving parts.

Those legs must be sturdy enouough to keep the case from vibrating and must be obviously solid, not hollow. But how can the viewers tell whether the legs are hollow? Even thin rods can be hollow. If the supporting legs were made of clear glass or lucite they could still be hollow and no one could tell. They would make fine pipes to convey moving air into the cabinet from a compressed air source under the floor. I can imagine two such hollow pipes forcing air into the cabinet and two on the other side acting to pull air from it, setting up a strong air circulation in the cabinet, invisible to onlookers.

A model windmill inside could be driven by the air, and in turn driving a large wheel, while onlookers might think the wheel was driving the windmill. Moving air usually makes noise. A generator [] 20 is mounted on an upper wall of the pendulum member 1. The generator 20 is operatively connected to the rotary support shaft 14 of the wind turbine 12 through a rotary transmission element 21 such as an endless belt.

Thus, the generator 20 is rotatable by rotation of the wind turbine It is preferable that, as shown in FIG. The reason is that the number of rotations of the wind turbine 12 may be greatly increased. A support cord [] 22 in the form of a string such as a wire or rope is rigidly connected to the piston 18 to extend right and left through the core of the piston As shown in FIG.

As shown in an enlarged portion of FIG. Specifically, each of the opposite ends of the support cord 22 extends through a receiving bore 24 formed in the support frame 23 to a position behind the support frame 23 , with a stopper 25 rigidly connected to each opposite end. A compression spring 26 formed of a helical spring is mounted on the portion of the support cord 22 between the support frame 23 and stopper The compression springs 26 apply a tension to the support cord 22 for constantly maintaining the support cord 22 in horizontal posture in the absence of an external force FIGS.

The piston [] 18 has gas sealing plates 27 rigidly attached to opposite, right and left sides thereof through mounting elements 28 to obstruct air flows between portions of the piston chamber 17 formed at right and left sides of the piston 18 and secure gas tightness for each of the right and left portions of the piston chamber A lubricant is applied to inner surfaces of the peripheral walls of piston chamber 17 to ensure smooth right and left sliding of the piston 18 and gas sealing plates 27 relative to the pendulum member 1. The gas sealing plates [] 27 , preferably, are formed of a flexible material such as rubber or soft plastic.

Numeral [] 29 in FIG. The guide rollers 29 prevent the support cord 22 from contacting peripheral walls of the penetrations 1 B to impair the smooth right and left sliding of the piston 18 relative to the pendulum member 1. A permanent magnet [] 30 acting as a field magnet is provided integral with a lower, transversely middle position of the pendulum member 1 , that is the lower surface of the support frame 2.

An electromagnet 31 is disposed in a transversely middle position on the upper surface of the base 3 A of machine casing 3.

The electromagnet 31 has switchable right and left polarities, so that, as described hereinafter, the polarity is reversible between north and south with right and left swinging of the pendulum member 1. Though not shown in the drawings, the number of field magnet [] 30 and electromagnet 31 may be increased to form two, three or more pairs. An increased number of magnets, preferably, are arranged at predetermined intervals in the right and left direction. In the case of an enlarged apparatus, it is preferable that an increased number of magnets form two, three or more pairs in the fore and aft direction also.

Next, operation of the pendulum type power generating apparatus in the above embodiment will be described with reference to FIGS. When the pendulum member [] 1 is not swinging right and left, the various components are in their respective home positions shown in FIG. That is, the pendulum member 1 is in a lowermost position in a right and left swinging track.

The piston 18 is in a transversely middle position within the piston chamber The support cord 22 has the compression springs 26 at the opposite ends thereof compressed to keep applying a force for maintaining this support cord 22 in horizontal posture.

The parallel swing links 4 remain still in vertical posture. When a force is applied to push the pendulum member [] 1 right or left from this stationary state e. At this time, the piston 18 in the piston chamber 17 is fixedly maintained in the transversely middle position by the support cord Consequently, the piston 18 slides leftward relative to the pendulum member 1 , and ultimately reaches the left end of the piston chamber 17 as shown in FIG. With the relative slide between the pendulum member 1 and piston 18 , air in the portion of piston chamber 17 to the left of piston 18 is compressed.

Conversely, air in the portion of piston chamber 17 to the right of piston 18 is decompressed. The compressed air flows with force into the wind turbine chamber [] 13 above through the left compressed air passage However, the outlet 13 D of lower compressed air passage 13 B is closed by the switch valve 16 to block entry of the air.

US20040179958A1 - Pendulum type power generator - Google Patents

The compressed air flows with force only into the upper compressed air flow passage 13 A. As a result, the wind turbine 12 is rotated clockwise by the incoming compressed air. This rotation of wind turbine 12 rotates the generator 20 to generate electricity. The incoming compressed air pushes open the switch valve 16 which has been closing the outlet 13 C of upper compressed air flow passage 13 A, and flows into the decompressed region, i.

The pendulum member [] 1 having swung rightward and reached the upper limit position is then swung down leftward by gravity. The pendulum member 1 reaches the lowermost position shown in FIG. At this time, the piston 18 in the piston chamber 17 is maintained in the transversely fixed position by the support cord Consequently, the piston 18 and pendulum member 1 slide right and left relative to each other.

The piston 18 ultimately reaches the right end of the piston chamber 17 as shown in FIG. With the relative slide between the pendulum member 1 and piston 18 , air in the portion of piston chamber 17 to the right of piston 18 is compressed. Conversely, air in the portion of piston chamber 17 to the left of piston 18 is decompressed. The compressed air flows with force into the wind turbine chamber [] 13 above through the right compressed air passage However, the outlet 13 C of upper compressed air passage 13 A is closed by the switch valve 16 to block entry of the air.

The compressed air flows with force only into the lower compressed air flow passage 13 B. The incoming compressed air pushes open the switch valve 16 which has been closing the outlet 13 D of lower compressed air flow passage 13 B, and flows into the decompressed region, i. In this way, the right and left reciprocating swings of the pendulum member [] 1 continuously rotate the wind turbine 12 in one direction to generate electricity with maximal efficiency.

In the above operation, the piston [] 18 inevitably moves to an increased height above the ground as the pendulum member 1 swings right and left upward from the lowermost position to the right and left upper limit positions. As a result, the support cord 22 assumes a horizontal, straight posture FIG. The support cord 22 would become loose, but this loosening is effectively absorbed by the compression springs 26 pressing the stoppers 25 right and left.

Consequently, the stoppers 25 can constantly maintain a fixed position relative to the pendulum member 1. The right and left reciprocating swings of the pendulum member [] 1 are greatly influenced by the permanent magnet 30 disposed on the lower surface of support frame 2 and the electromagnet 31 disposed on the upper surface 3 A of machine casing 3. The working of these magnets will be described next with reference to FIGS.

For expediency of description, it is assumed here that the permanent magnet [] 30 on the pendulum member has the north pole at the right end and the south pole at the left end. First, as shown in FIG. At this stage, the south pole at the left end of the permanent magnet 30 of pendulum member 1 continues being attracted to the north pole at the right end of the electromagnet This promotes the leftward swing of the pendulum member 1 to a maximum.

Next, as the pendulum member [] 1 continues to swing leftward to reach a stage where, as shown in FIG. That is, the right end of electromagnet 31 becomes the south pole, and the left end the north pole. By switching the polarity of electromagnet. Further, the south pole at the right end of electromagnet 31 begins to attract the north pole at the right end of permanent magnet This acts to swing the pendulum member 1 further leftward. Next, as shown in FIG. At this stage, the polarity of electromagnet 31 is reversed right and left again.

That is, the right and left polarities of electromagnet 31 now coincide with the right and left polarities of permanent magnet With this polarity switching of electromagnet 31 , the south pole at the left end of electromagnet 31 and the south pole at the left end of permanent magnet 30 repel each other, and so do the north pole at the right end of electromagnet 31 and the north pole at the right end of permanent magnet Thus, no attraction occurs between the two magnets 30 and As a result, the pendulum member 1 becomes completely free from a force that brakes the swing thereof The pendulum member 1 continues being swung leftward lightly and smoothly by gravity and an inertial force acting leftward.

The polarity of electromagnet [] 31 remains unchanged until a stage shown in FIG. The north pole at the right end of permanent magnet 30 continues being attracted to the south pole at the left end of electromagnet This promotes the leftward swing of pendulum member 1 to a maximum.

Fake perpetual motion machines you can build.

Immediately before this stage, the polarity of electromagnet 31 is switched again. Thus, the electromagnet 31 now has the left end providing the north pole and the right end providing the south pole. With this polarity switching, a mutual repulsion occurs between the north pole at the right end of permanent magnet 30 and the north pole at the left end of electromagnet This results in a force that pushes the pendulum member 1 further leftward.

The pendulum member 1 continues being swung leftward lightly and smoothly by gravity and an inertial force acting leftward. The pendulum member 1 finally arrives at the upper left limit position shown in FIG. The pendulum member [] 1 arriving at the upper left limit position will swing in the opposite direction rightward next. The polarity of electromagnet 31 is switched in the order reversed from the above.

Under this control, as described above, the pendulum member 1 continues being swung rightward lightly and smoothly by gravity and inertial force. As a result, electric power is obtained continuously.

Revolving Shaft Without Power.

In the above construction, the parallel swing links for suspending the pendulum member may be pivotally supported in intermediate positions thereof by a machine casing, each of the parallel swing links having a balance weight attached to an upper end thereof. Would a pendulum swing indefinitely in a frictionless vacuum? Conventionally, electricity is obtained from varied sources such as nuclear power, thermal power, water power, wind power, solar radiation, fuel cells and so on. In the above operation, the piston [] 18 inevitably moves to an increased height above the ground as the pendulum member 1 swings right and left upward from the lowermost position to the right and left upper limit positions. These toys do not have a perfect vacuum. From there the mercury drips onto the wheel W 2 at the left, turning it, and also the pulley K 1 driving belt K that runs up to drive pulley K 2 and then something else unspecified. Send comments, corrections and additional ideas to the address shown at the right.

The balance weights [] 9 disposed at the upper ends of parallel swing links 4 are effective to produce the inertial force for the right and left reciprocating swings of the pendulum member 1. Next, the construction shown in FIGS. In the following detailed description, parts identical to those of the foregoing embodiment are shown with the same reference numerals, and are not described again.

The piston [] 18 is vertically movably supported by support poles 32 erected on the base 3 A of machine casing 3. Specifically, the piston 18 has support arms 33 formed integral therewith and extending fore and aft from a core portion thereof. Thank you for your interest in this question.

Magnum 1 1 4. Vatsal Manot 1 John Rennie k 41 Gravitational wave emission cannot be removed. Gravitational wave emission can be removed if the pendulum motion has no quadrupole or higher moments. True, but I must confess I can't visualise what kind of "pendulum" that would be. Not that I'm particularly good at visualising quadrupole moments. Actually, I'm asking this as a question: Does a pendulum emit gravitational waves?
