Nope, sorry.

I'm not certain you understand the concept.
In order for something to be a perpetual motion machine it would have to create more energy than put into it. It has to be able to use that excess energy not only to overcome its own friction, but also be able to do some sort of "work." Not simply move for a very long time.
Even something like a fusion generator wouldn't be considered a perpetual motion machine because it uses a consumable fuel.

perpetual motion machines were conceived with the hope of them being upraded to tap energy from them above the amount required to keep them in motion . voyager wouldn't fit that concept , but most certainly is a man made machine in perpetual motion !

Well, by that definition, so is a cruise ship.

Sure there is; just go up. Gravity falls off (slowly) over miles. A large enough device could see a significant gradient.
But that doesn't matter. A gradient of any force (gravity, magnetism, charge attraction) won't give you energy, even with clever devices.
Yeah, taking it to an extreme, a black hole's gravitational field can have a very large "gradient" across atomic distances.
So?
Maybe some energy could be extracted from the so-called "Hawking radiation". A virtual particle/antiparticle pair appears, because of a vacuum quantum fluctuation, near the event horizon and one of them is sucked into the black hole and the other is emitted as radiation before they can zap each other. I suppose that is one way to "extract energy from the existence of gravity..." because of a gravitational gradient. Probably wouldn't be very useful for weight reduction, space drives or skydiving in the near future though.

QuoteOh, well now I'm not sure I'd agree with that Champu, after all, fantastic musings about this neat new force we don't understand yet in the 1800's eventually led to highly evolved and useful toys based on manipulating that force, like the computer you typed that message on.
Electricity ring a bell?
"What!? By using this com-PUE-ter I'm using 'lectricity!? Not on my watch!*"
But in all seriousness... there's a difference between musings and fantastic musings. A better understanding of the underlying nature of gravity may indeed allow us to create some cool technologies that we don't currently have, but that's no reason to revive all the snake oil claims from the 1800's about electromagnetism that didn't come true.

If you cut the engines on a cruise ship, it will coast along for half an hour or so. If you cut the engines on Voyager, it will coast along for centuries or so. But eventually both will come to a stop, due to either drag or running into something.

outer space is a vacuum , therefore no drag , voyager is no longer being propelled . all propulsion was cut prior to it leaving our solar system . the chances of collision are miniscule compared to the vastness of space. it will continue unimpeded to the end of time , or to the end of the universe , whichever comes 1st !

>outer space is a vacuum , therefore no drag . . .
Incorrect! Outer space is filled with gas (mainly hydrogen) and dust. Even in the cleanest part of space you see densities of 1-2 particles per cubic meter. That generates an infinitesimal amount of drag, but it is present, and will eventually stop Voyager. (Although as I mentioned it's more likely to hit something first.)

if it encounters drag constantly it will slow and eventually stop , collision odds are negligable. it might come close enough to a large enough body to be influenced by it and the likely result would be a slingshot effect. but remember there are many celestial objects that have been in motion since as far back as can be measured and will be as far as can be projected. voyager now joins them !

But on the other hand... the density of many posters in SC is severly affecting the entire solar system.

Voyager is constantly under the influence of "motive force". It is called gravity. Voyagers path is constantly being altered by the ever changing influence of the gravitational forces of countless bodies. Voyager may be perpetually moving, but it's motion is determined almost entirely by outside forces. This is just the opposite of what a perpetual motion machine is required to do, which is to operate for an infinite amount of time without energy being added once the motion has started.
