Question Would this be a good idea for perpetual motion?
I got this idea while studying about water clocks -- http://en.wikipedia.org/wiki/Bernard_Gitton --. Basically I want to run a siphon system over a water-wheel: Take an open water tank (Tank A) filled with a reasonable amount of water, then raise an air-tight tank (Tank B) over the other. Tank B should have a spout of some kind to let water flow out, as well as a hose leading into Tank A to allow water to flow in. If the spout on Tank B let water fall into Tank A, then the motion of water would continue forever, right? So if you were to place a water-wheel under the spout, you could use it to power other things. ... If that wouldn't be classified as perpetual motion due to evaporating water, could you substitute something oily instead?

Best Answer No, this would not be an example of perpetual motion due to the counter-effects of gravity. If Tank A is lower than Tank B, it will take more energy to raise the water back into Tank B than you would gain from the motion of the water wheel. Thus, your system is losing energy during the process. You could get it to run for a long time with a large enough tank, but eventual entropy wins and the system will stop. Even if you wanted to dedicate 100% of the energy generated by the water wheel to a pump to push the water back up into Tank B, the amount of energy generated in the water wheel is less than the energy necessary to move the equal volume of liquid back into the elevated tank. Energy would be lost by the friction of the water particles as they fell through the air, the loss of energy to heat as the water droplets impacted the blades of the water wheel, the loss of energy to heat and friction as the water wheel spins on its axel, etc. Unfortunately, a practical perpetual motion machine just isn't possible in an environment where friction and gravity exert an influence. Hope that makes sense!

Question Why are perpetual motion machines impossible?
How can it be impossible? I have an idea that involves a water wheel and it keeps going in a circle. If I had the right equipment, I would build it but I don't so I would like to know HOW it is impossible. How is it impossible to make a machine machine NEVER stops going? I mean, If you use water and do it right, then the machine won't stop, so HOW?

Best Answer If you are thinking about hydro-electric power or the "drinking bird"...both of these may appear to be the perpetual motion machine. However, both of them depend on nature's power cycle to operate, which involves evaporation of water caused by the sun, condensation of water vapor into droplets, and rain. The drinking bird will continue its repeated motion as the water dries off its head. Once fully dry, the bird will take a dunk in the dish and absorb water. When the dish is fully empty, or the background begins to fog (which ever comes first), this will no longer be a perpetual motion machine.

Question Can "free energy" (perpetual motion) be achieved through buoyancy?
The easy answer is "no, because of the law of conservation of energy", but I would still like to scientifically discuss the following idea: Imagine an underwater "ferris wheel" inside a large water tank such that there are upside-down cups on the outside perimeter of the wheel. At the bottom of the water tank, there is a small hole through which air is pumped, so that it fills the cups with air as they pass over it. This results in circular motion of the wheel as the cups are filled as they pass over the hole, and emptied as they reach the water's surface. What I am wondering is how much energy would be required to get air bubbles through a hole in the bottom of the aquarium into the cups, and how much energy could be produced by the rotation of the wheel. I would be interested in seeing actual calculations. I do not have the background in physics necessary to answer those questions, but it seems to me that it would take very little energy to pump the air through. The wheel is connected to some kind of electrical generator, which is used to power the air pump. The real question is whether enough power can be extracted from the wheel's rotation to power the air pump.

Best Answer First of all, this is not free energy. You have to pump air into it. The energy required to pump the air depends, among other things, on the resistance to the air motion. You also have to consider the resistance to the cups when they are moving down. Now if all the cups have air, then you reach a point where the clockwise moments = counter clockwise moments. With the resistance, the ferris wheel will eventually reach a state of zero motion. Even if there is no resistance (purely theoretical), then the wheel will attain some constant angular velocity, and will thus have a certain amount of kinetic energy. That's still fine, UNTIL YOU START EXTRACTING ENERGY FROM THE SYSTEM. If you want to put that energy to some useful purpose, then eventually you'll extract all the kinetic energy it possesses. So it will give you some energy for a short period of time, and you will find that this energy is equal to or less than the energy you put into it via the air. RE: the additional details you posted. Look at it this way. If you input 5 J of energy into a system (via the generator). At best the system will give you 5 J of output. In reality it will be less. So if you take all of this 5 J and re input it to the generator, then you have nothing left to output. And in reality there are losses during energy conversion. These problems work best when the rotation is caused by some natural means e.g. flowing water from a river or waterfall, or wind etc. That way you don't have to provide the input. Nature does that for you. You might be interested in the article below.

Question Do magnets affect perpetual motion in space?
(in space) if a metal magnet ring surrounds a rod of metal that you set spinning, will the magnetism eventually slow down the spinning rod, or will it just center the rod inside of the ring and allow it to spin as long as it is undisturbed?

Best Answer Depends on a couple things. The direction the rod is pointed and the direction it is spinning. If the axis of rotation of the rod, the axis of rotational symmetry of the cylindrical shape of the rod, and the magnetic moment of the metal were all pointed in the same way, no current would be induced in the metal rod and it would not slow down. But it would not automatically center itself. If the magnetic moment wobbles, or the metal moves in any way which is not along its axis of rotational symmetry, it will not be a maintainable situation. If there are any currents induced or if the magnet itself is producing a time-varying field seen by someone nearby who is not rotating with it, it will slow down.

Question Perpetual motion with earth magnets. Science Fair. Need examples DONT NEED STUPID or "CAN NOT HAPPEN" comments
I am trying to research a more in depth way of discovering perpetual motion. The best I can figure out is magnets. Although they because useless overtime it is the beset in terms of efficency. Any ideas that might work? Like the nail and 1/2 watt bulb?

Best Answer You can't make anything with "real perpetual motion", but you can make devices that keep extracting power from their surroundings as long as the power source is available and they remain in working order. A science fair project explaining the difference might work. In principle, you can extract energy from the earth's rotation. It would seem as though you could do so with a pendulum or gyroscope You could have a Foucault pendulum with a piece from an old-fashioned grandfather clock that keeps the pendulum swinging despite friction, only driven by the apparent rotation of the pendulum. Or you could have a gyroscope that's kept turning by its own precession. Either way, what would make or break the project is the writing along with it. You would need to write about Foucault pendulums or precession of gyroscopes, but you would also need to write about conservation of angular momentum, and explain why it's a problem for the device in question, and what in the real world actually *does* extract energy from the earth's rotation.

Question I need some blueprints/pictures of some perpetual motion machines that are powered by strong magnets. Help?
I am doing a science fair project on perpetual motion and free energy. The problem is, I am unable to uncover any pictures that are helpful. They must be of a perpetual motion machine that is powered by magnets, but it can't be powered by electromagnets. If you can find some please just post the link below.

Best Answer A lot of people seem to use the latin term "perpetuum mobile", so you might find that a useful search term as well. When I used that search term I found this very nice historic web page. http://www.hp-gramatke.net/perpetuum/index.htm Look around there, I assure you magnets are mentioned. Lots of diagrams too.

Question How is it that creating perpetual motion machines is impossible?
A violation of the laws of physics. I know that other impossibilities include time travel, telekinesis, and faster than light travel. Can anyone give me some examples of perpetual motion machines?

Best Answer it is not impossible it's very easy to do and yes it can be done without going anywhere near any 'laws of thermodynamics'......,,, i know because i made it without trying to, and without any @sshol3s telling me it's 'impossible' it's easy to do something when people don't tell you 'it's impossible' before you start

Question I want some good examples of a perpetual motion machine I have the answer.?
Magnetic force is the key simple but no has done it magnetic force repels to create rotation if applied right the force could be harnessed to create rotation this constant frictionless rotation could be used with simple coils for electricity. This would be perpetual motion no outside energy required its like using gravity minimal outside or no outside help would be required. Give me ideas if you think your smart?

Best Answer perpetual motion machines my magnetism even in a frictionless vacuum region will not work. first of all, energy is lost due to hysteresis. no need to concern about heat losses from friction. and because of lenz's law, any work you try to extract from the machine will lead to the slowdown of the machine because the magnet opposes its own movement. perpetual machines dont work because there is a concept known as entropy, which is listed in the laws of thermodynamics. as long as these laws stand, perpetual machines exist only in the universe of the mind.

Question Examples of Perpatual motion machines?
i need to make a perpetual motion machine for school i know it is impossible but i need to come as close as possible. with simple materials, what are some designs that might keep something moving afor the longest period of time possible. thanks

Best Answer Fake one. Get yourself a small motor, a strong speaker magnet, rig it up so that you can stick it under a wooden table, or make a hollow display box to conceal it. Get a so called "perpetual motion machine" and sit it above the rotating magnet on the table or display box. Make sure the PMM has another small magnet fixed to it, and can spin relatively free (use a bicycle wheel etc with bearings). Cheers. Exp.

Question Where is free energy? Magnetic motors, hydrogen motors, perpetual motion generators?
Why is it not on the shelves or in ebay catalogs?

Best Answer This kind of stuff is still not mass marketed mainly because of skepticism around the world, I have personally found magnetic energy generators to be the best option for alternative energy. They require no light, no wind or grid electric to even start, and once they are working they don't stop for years to come. Many people are unaware that you can easily build your own magnetic energy generator from common easy to find parts. It's a shame more people don't build magnetic energy generators as a device like this could rid us all of the current energy crisis. Check the source below for more information.

Question How does a Magnetic Generator work? (Magniwork)?
NOT a Perpetual Motion Machine, those do not exist. If you know how Magniwork works, then please let me know. That is really what i'm trying to find out! Could you please leave a source if possible? Thank you in advance!

Best Answer An electric generator is a device or machine that is used to convert mechanical energy into electrical energy. It is based on the principle of electromagnetic induction, a scientific law that was discovered by British scientist Michael Faraday and American scientist Joseph Henry in 1831. The principle states that when an electric conductor, such as a copper wire, is moved through a magnetic field, electric current will flow through the conductor. The mechanical energy of the moving wire is converted into the electric energy. Faraday and Henry found that when you move a magnet in a coil of wire, electric current is generated. # Faraday's law of induction shows that a moving magnetic field will cause electrons to move. Generators create electron movement in the copper wire coils contained within by moving them through a magnetic field. Faraday built the first electromagnetic generator, called the Faraday disc, which was a simple copper disc rotating between the poles of a horseshoe magnet. It produced a small DC voltage and large amounts of current that was inefficient, but a good start for future generators. # Generator magnets apply pressure to the electrons to push them and create a flow or current of electricity. The number of moving electrons is called the amperage or the current and is measured in amps. The pressure pushing the electrons is called the voltage and is measured in volts. # A generator is basically created by a mechanical force that turns a conductive wire or bar within a magnetic field. The force used to spin the conductive object can be provided by many sources, such as moving water, steam, wind, gas engine or even hand-cranked levers. The electricity then flows into an electric motor or other electric-powered device, which reverses the process and the electricity makes it move. Small generators create a magnetic field with permanent magnets. Larger generators create a magnetic field with a set of metal coils with electric current flowing through them; this is an electromagnet. # There are many types of generators. Each is based on the method it uses to either spin a conductor through a magnetic field or a magnet through a conductor. Some include the following generators and/or examples of devices using generators. Magnetohydrodynamic generators creates electric power from hot gases moving through a magnetic field. Pre-1960s vehicles used DC generators with electromechanical regulators but have been replaced with alternators, which are cheaper, to recharge the batteries. An alternator is a type of generator that creates a magnetic field that rotates and passes through coils to create an electric current. Engine generators are the combination of electrical generators and engines that are used in piston engines or gas turbines, such as small portable gas-powered units to large turbines. Hydroelectric power plants use falling water to turn a turbine, which provide the mechanical energy to turn the generator and create electricity. The electricity is then sent through transmission lines to deliver electricity to homes or buildings. Some sail boats use water or wind-powered generators to charge the batteries through the use of small propellers, wind turbine or impeller. Human-powered electrical generators are used in devices such as portable radios or flashlights with a crank. Small generators are used in bicycle lights and powered by riders see yaaa sanjo

Question I "Want" to buy a magnetic Generator. oh please may you help?
im like having an Obsession trying to find a sight that can sale these things even if they are prototypes. im totally interested to almost near desperate! if i get any worse i would be forced to build my own witch is the last thing in my life! Medium or big doesn't matter. just hoping to cover our fridge and heater. they work by perpetual motion with a little electricity added for more power.

Best Answer Have you tried going to google and typing "magnetic generator" in their search box? Oh, and there's no such thing as "perpetual motion". Good luck with your scheme, but I'm quite sure you'll wind up needing to use electricity from the electric company to keep your household appliances running.

Question where can i buy perpetual motion generators?
i want to know where i can buy a perpetual motion generator? I need to know where i can buy a kit for it. Please help. Thanks in advance... Lukeaduke200

Best Answer There are lots of "perpetual motion" toys. For example: http://www.sciplus.com/category.cfm/subsection/1 You can generally find them by googling things like "magnetic toy" "perpetual toys", etc. This one is a radiometer; it uses momentum from sunlight to rotate a low friction rotor. There are also neat ones that use water or batteries. Of course, these "perpetual" machines are not really perpetural. They are just using a clever or hidden power source. No such thing as a real perpetual motion generator, though lots of people have spent lots of money trying to get one (most of the money was scammed from investors).

Question How to build a perpetual wheel?
Hi everybody in in grade 7 and am doing a science fair and need some help. i need to now how to build a perpetual so i can build it.if you can can you put some pics that will help me a lot. thanks a lot to everyone who who helps.

Best Answer Jimbo, let me introduce to you the laws of thermodynamics. Specifically law #2 "The second law of thermodynamics, which states that the entropy of an isolated macroscopic system never decreases, or (equivalently) that perpetual motion machines are impossible.." I.E. in layman's terms you never ever get more energy out of a system than you put into it, and in fact you can never ever get as much out as you put in because there are ALWAYS losses in the system. Friction, air resistance, gravity, hysteresis. all of these sap energy from the system. Ergo, entropy MUST increase.

Question do you think that it is possible to build a perpetual wheel?
I been giving it a lots of thought and I think it is possible and I will attempt to start building one about 2 months from now when I am less Bessy.I will be using magnets to unbalance a wheel. Joel- No,my project will not be related to the motor effect in fact it will not have anything to do with electricity yet. Benjamin - Thanks for your support.

Best Answer Although it defies the very law of conservation of energy, personally i do believe that it can, and will be done. Eventually. Will your project be somehow related to the motor effect?
