The misguided search for a perpetual motion machine has run substantially longer than any attempted perpetual motion machine. |< <? > > XKCD has this right, both as an Internet phenomenon and regarding the alarming degree of scientific ignorance out there in the public. An example relevant to thermodynamics: About a decade ago, I was given the task of dealing with an enterprising young man who had designed and built a device that he thought would in fact be a perpetual motion machine Der zweite Hauptsatz der Thermodynamik besagt, dass man das nicht kann. Wenn Sie könnten, könnten Sie eine Perpetual-Motion-Maschine bauen. (Weitere Behauptungen, die ich hier weglassen werde) Ich glaube weder der Behauptung noch folge ich einer der Überlegungen. Erstens verstehe ich die Sache mit der Perpetual Motion Machine nicht Step one: Perpetual motion Step two: ??? Step three: Profit! Enjoy your pondering. Like Lik The non-existence of perpetual motion machines is a central tenet of physics, whatever people on the internet say. CQT researchers have found that you need the quantum world's uncertainty to uphold this principle. Comic by xkcd.com. Why should nature have this fuzziness? The new work gives us some kind of answer. Stephanie and Esther show that if we could break the quantum uncertainty principle, we could also break thermodynamics' second law. If quantum physics weren't uncertain.
Physics for Entertainment was written by Yakov Perelman in the 1920's (in Russian) and updated periodically through the 1930's. There are actually two parts to it, but Volume 1 is long out-of-print (though findable online — more on that later) First, let's get a few things out of the way: In real life, we can't put a metal pole between the Earth and the Moon.For one, someone at NASA would probably yell at us. The end of the pole near the Moon would be pulled toward the Moon by the Moon's gravity, and the rest of it would be pulled back. nothing which was what the inventors of the perpetual motion machines sought to achieve. It is supplied from an outside source in our particular case, the surrounding atmosphere where it is stored up by sunlight. To all practical intents a gift-power machine would give the same advantage as could be derived from a perpetual motion
Update: I'm finally home after a month or so of nonstop events, including several xkcd book fund-raisers/signings. I met tons of cool people, we raised a lot of money for the EFF and Room to Read, and at one point I signed a book for a robot. Thank you to everyone who ordered a copy, by the way! I hope you like it. They're shipping out nicely, and we're about ready to order a second printing First, I don't get the thing about the perpetual motion machine: If this is regarding the first law of thermodynamics (conservation of energy), then it's perfectly possible to lose energy while still heating up an object, which would avoid perpetual motion, so I don't get the argument Alt-text: The misguided search for a perpetual motion machine has run substantially longer than any attempted perpetual motion machine.

He also spends a lot of time discussing why various perpetual-motion machines won't work. it's interesting to see that there was as thriving a community of free energy people a century ago as there is now, many of their designs based on the same misapplications of physics XKCD 1166: arguments about perpetual motion; Abstruse Goose 319: Maxwell's demon; Fluids.

IF you can build a perpetual motion machine, it should work fine in space as well as on Earth as long as it doesn't depend gravity.

Even in space, there's a tiny, micro amount of friction--which would become very, very important as you accelerate. Effectively, in this case, externally generated electricity turns into thrust. Energy goes into the system. Thrust comes out. It's no different from a conventional rocket except that you don't.

Since perpetual motion violates fundamental laws of the universe, it wont work. The flaw in your idea is that it appears, from your description, that the magnets get pushed from one magnetic field to another, what you have ignored is the fact that at it enters the next magnetic field it will be slowed down again by the repulsion. Using magnets to levitate trains is an old idea and is actually.

Perpetual Motion in itself would be a nice curiosity if it were even achievable lol!! Problem gets even worse though. In order to get a perpetual machine to do work, you need (more energy out than put in) in other words it needs to make more power than it uses to keep itself running. Something has to propel the car or whatever load one places. Perpetual Motion. A perpetual motion machine is a machine that uses its own motion to fuel its own motion, and also performs work (i.e. applying force to move mass a distance, any distance) as a byproduct of this motion performed by the machine that perpetually performs the motion performed by the machine. Infinite Battle from EyesMaze. Renewable energy sounds so much more natural and believable than a perpetual-motion machine, but there's one big problem: Unless you're planning to live without electricity and motorized transportation, you need more than just wind, water, sunlight, and plants for energy. You need raw materials, real estate, and other things that will run out one day. You need stuff that has to be mined.
Hints on efficient mechanics: models based on Nathan's perpetual motion experiments could at least do something clever, and perhaps create free energy.

A perpetual motion machine is usually defined as something that moves perpetually while giving off energy. If you don't include that last bit, a pendulum in a vacuum is a perpetual motion machine (give or take the difficulties in producing a perfect vacuum). -- Tango 11:40, 27 October 2008 (UTC) It would have to be a pendulum in a perfect vacuum with a frictionless bearing - which is.
$\begingroup$ To put an experimental spin on it: no repulsive gravity has been observed and the accepted theory is modeled in such a way as not to allow for it. The theorists can explain to you how that works, but the gist is that one can only make theory for what has been observed.
