I will however make a supportative statement; near frictionless mechanics is fairly simple and easy.
Please do since the rules here require it. Simply making a claim that something is possible is NOT scientific at all. As a matter of fact the steady stream of unsupported claims we see here is very annoying so act like a scientist and post some proof.......NOW.

This is a gross and self-serving misrepresentation of the posts above. This statement indicates a either an intent--rather pointless I might say, given the audience--to gain sympathy for "persecution" of your opinion, or a complete misunderstanding of the meaning of "loss of energy" in an open system.

Conservation of Energy applies only in a "closed system". Any "machine" "loses energy" because it is an open system and loses it to the surrounding environment.

The challenge in a "perpetual motion machine" is that there is no way to capture that loss and harness or redirect it. Various machines do indeed use mechanisms to recapture heat and other elements of energy within the machine, however in most machines that ability to capture that energy before it is lost is quite low.

If you properly understand the terms "open system" and "closed system" then you will realize that the principle of Conservation of Energy provides no support whatsoever to the notion that perpetual motion exists, in fact it directly indicates that it is impossible, because it is not possible to create a perfectly closed system, and even if you did, it would do you no good! Don't you want to use that power for something? Then you'll need to "open" the system that contains your machine!

If you would like to borrow a mirror, I'd be happy to provide one.

You can save the planet if you provide this. So please do!

To keep this secret to yourself would be a crime against humanity.

Close enough for you doesn't mean that it actually is perfect. In any case, there's no point expecting to make much money from it, at the most you could use it as a storage of energy. No great novelty.

It doesn't even make sense to give a percentage, without a time scale. Could you say what fraction of orbital kinetic energy planet Earth loses? No, because it depends on the time period you're talking about. The fraction is very tiny, even over centuries; it's even tinier over a matter of hours. In a given time, it loses a much larger fraction of rotational kinetic energy due to tides, but again it's just a matter of what fraction in what time.

For others here, I'll try again to make the distinction. To what extent dissipation can be eliminated is a practical issue. The consequence of thermodynamics is that not all of thermally dissipated energy can be reconverted, but thermodynamics does not address the matter of how well dissipation may be eliminated in general. As far goes thermodynamics, a process may be reversible if it takes place in thermal equilibrium; this means infinitely slowly for a heat engine so, for these, one can only say the nearer TE the less irreversible it may be. It has no bearing though on non statistical mechanical matters such as reducing friction.

Entropy only comes into relevance once there has been a thermal dissipation. If Maxwell's demon could work, friction and the likes wouldn't be a such a concern but, without these, entropy wouldn't be a concern. Entropy alone isn't sufficient to prove the case.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
