u cannot have a perpetual motion like tht.first we need is a frictionless inertial system which can accelerate for infite time upon the application of a single force.
this kind of system is very much in dreamland in the exa-universal system. but deep down inside who knows how some unknown particles behaving or behaves..

You dont really need a perpetual motion machine.What you need is just a machine that does a lot of work for very little input.The birdie which drinks endlessly a toy we see in most houses is a good example of a near perpetual motion machine and that should be enough.It would be great even if we just found some gift motion machines , which use inexhaustible natural forces to do work , eg: hydroelectric power station under waterfalls , solar sails , etc...

That's what the magnet motors supposedly are- very low power input force amplifiers.

Anything that puts out more than you put in is by definition a perpetual motion machine. IOW, it is a violation of 2LOT.

Like the country bumpkin said when he saw his first giraffe at the zoo: "There ain't no sich animal."

Hydropower is "free energy", because we don't pay the sun to shine. But even the sun is not a perpetual motion machine.

What about a compass yes it reads an ouside magnetic source but its the natural "pole" of the earth and its rotation?

A compass has an external force acting on it creating the impulse.

The closest thing we have to a Perpetual Motion machine is a pendulum. The basic idea is no loss of KE, which is impossible as no process can be 100% efficient nevermind have greater efficiency, according to thermodynamics. It's not really possible to get closer then a pendulum in minimizing inefficiencies, sorry.

It doesn't have to do with the fact your car will require refueling and maintenance preventing it from running indefinitely, which is analogous to a compass as you used it.

The Chap

"Perpetual" is the key. As has quite rightly been alluded, it is in theory possible to create a device that will simply continue to function within a closed environment until such environment ceases to exist. "Perpetual" suggests, nay requires, an open system in positive and negative temporal terms thus necessitating a steady state universe.

Even within the bubble universe that is The Orthodoxy within the cosmological
and indeed astronomical community, infinities are paradoxically confined within the space-time posited.

Getting useful work out of something that goes on and on and on is an experience confined to the yack and credit card bills of my ex-girlfriend.

You know you were all waiting for that.

On a more local level many over parity ( in terms of thermodynamics ) devices
involving such eclectic disciplines as hydrodynamics, civil power engineering, comercial electronics etc. continue to through up the most disturbingly consistent anomolies.

Very high tension coupled with very high frequency is the most recalcitrent of any mugs line up.

To dismiss this - as is usual - as Tesla madness is idiocy of the highest order. In my lowley estimation.

Recently in New Scientist there was an artical ( Fortean Times reported yonks ago) about a reactionless drive that exploits, quite cunningly, relatevistic asymetry.

More things in heaven and Earth Horatio ... !

why not our own earth is spinning (sun gives it energy), so why can't we make a machine that uses the same energy as earth.

The Chap

You may need to re-phrase that sir.

Nanovae

science have proven for century perpetual motion is a myth.
It's not a question to know if it's possible or not, it's a question to know why it's not possible.
thermodynamical laws answer that easily.

evolution of perpetual motion ?
I don't get it Omon, could you refine a bit please (the thread link is sooooo big ...)

You would be right if both theories would contradict each other . Alas, the writer of the original article has 2 fundamental flaws in his thinking.


1. Earth isnt a closed system
2. Even in a closed system you can increase the order in a part of the system as long as the order of the whole system goes down.

Believe me if two well accepted theories contradict each other scientists are the first to yell and discuss about it... Not resting until they find a better way to explain both... They don´t say: God made it that way dont question it.

They ask and ask and sometimes they come to conclusions which contradict common sense and well known truths... This is why so many people dont like scientists.

In a finite scale it seems we are seeing perpetual motion in the fluctuation of our universe. The ebb and flows from hot and cold, creation and destruction always seem to be in constant flux. Will they someday come to equilibrium and cease to exist? It is anybodies guess. But who started that pendulum rocking? That is the greater question. Science is always changing its views because it lacks absolute knowledge, this is why scientist can not be absolutist. When we plumb the depth of the heavens for answers we will be doing so infinitely, because the stuff of the universe is infinitely changing, changing ones point of reference. So the answers are like humanity, they are but a vapor, here today and gone tomorrow. Science is for the day but G>D is forever, His ways never change, He is absolutely infinite.
