Exploring Perpetual Motion Machines: A Fun Site by AAAS and LHUP

[Mr. Robin Parsons]

This is a fun site, again brought/linked up to you by the People of the Journal Science, The "www.aaas.org"[/URL]

This is about perpetual motion machines that kinda don't quite make it, [PLAIN]"www.lhup.edu/%7Edsimanek/museum/annex.htm"[/URL]

 

[Mr. Robin Parsons]

BTW as a short notation, when it comes to "Perpetual Motion Machine, if we remove the word 'machine'. and simply look for Perpetual Motion, we find that, the Universe itself, as NONE of the Atoms that comprise the Universe has ever been proven to have stopped going/moving, is our only comparision for what is, (would be known as) perpetual motion.

(Insert age of Universe *here*, that is how long it has all been moving!)

Sorta kinda not really. See, while it's been going for some time, I believe it should eventually run out of expansion juice and things will start slowing down. Could be wrong though.

So then your professed belief is that (if) When (according to you) the Universe stops expanding, you think that therefore, then, the ATOMS are going to stop spinning, or cease motion altogether??

If that what you think/ Cause, "No offence", but it is wrong!

Ok,a lot of those tell us that their machines have frictionless parts...isnt that enough to disprove the claim of perpetual motion??

If they could come up with frictionless, then perpetual motion would be way more likely achievable, as friction is the main reason why 'perpetual' isn't possible!

Exactly..thats what I am saying..since its almost impossible (is it?) to have something be 100% frictionless, when they say "assume its frictionless" it kills their "invention"

 

[Mr. Robin Parsons]

Oh So sorry, I hadn't gotten that from your post.

Yes, I would suspect that once someone stated "Assume it is frictionless" I too would begin to doubt it, unless it had no moving parts, but then it wouldn't be doing any "work', now would it!

hmm, I didn't say that. You must remember I do not believe in fairy tales. Anyhow, I meant I believe I heard a theory which states something similar (more technical) that I said previously.

No offence taken, for its not something I care about that much, was just relaying something I've read either here or on one of the various websites, I'm sure someone could explain better then I.

I think the frictionless b.bs are nano tech right? Also I believe gravity has a good bit of play in not allowing pm machines.

 

[Mr. Robin Parsons]

Well, you have expressed it as a belief, sorta, but I can figure out that you meant matter, and perhaps were not thinking at the atomic scales were ceasation of motion is, to date, completely unknown, unseen, and thougth as undo-able.

 

[megashawn]

I think what i was talking to is one of the conclusions the 2nd law of thermodynamics leads you too. Entropy death or something like that.

I think me and you (mostly me) just misunderstand one another alot.

 

[Cummings]

it would be quite good if some of the machines worked..i would like to build em but some just a little to complex for a little phisics student.

For somthing to be frictionless, you would have to be working in a vaccume and with superconductors and electromagnets.

one day..one day.

 

[KillaMarcilla]

I think the thing isn't perpetual motion, but rather turning useless random (such as heat) energy into useful work

If you can do that enough to overcome the friction in your device, you're set, and then frictionlessness is just a calculational convenience
