Yes I've seen those vids by GotoLuc (tho I frequently fall asleep due to his voice, but that is an other issue).


As you seem to be into magnetic shielding, I'd be glad if you take a look at my shielding challenge in my "Searching for Buddy..." thread, tho, no strings attached etc. ^^

Maybe we can continue this topic on a general level about all aspects and findings about shielding.


I am currently confronted with that, once again ^^


Well isn't it that we all wish we had a shield that shields, but is not ferromagneticly attracted by the magnet it should shield? Not only because of the huge losses by the coghing.


So that is on mY wishlist. But how to achieve it. Let's see. Probably I could use several layers, alternating thick diamagnetic layer, thin ferrogagnetic layer, and by doing so, compensate the attraction. Only diamagnetics are very week, at least the available materials.


What diamagnetics do we have anyway? I got some pyrolytic graphite here, is there something better?

Yes I'm committed to doing good science.

Once bitten twice shy. 

I'm still sometimes in too much of a defensive mode, here (others are as well I think).
Many trolls are highly knowledgeable, and effective.
A two week long multi troll siege on ones topic is not much fun.

I prefer to keep my topics available to the non expert ( as I am non expert myself).
This presents its own kinds of  difficulties. 

I welcome expert advice, expertly, non expert presented. smile

Sinc you are committed to doing good science, I dare to present some good science about magnetic shielding:

http://www.magnetic-shield.com/pdf/how_do_magnetic_shields_work.pdf

I cite from this document: "Magnetic shielding materials re-direct a magnetic field so it lessens the field's influence on the item being shielded. Shielding does not eliminate or destroy magnetic fields, nothing does."

http://www.magnetic-shield.com/pdf/will_magnetic_shield_block_the_fields_effects.pdf

I cite from the document: "There is no known material that blocks magnetic fields without itself being attracted to the magnetic force. Magnetic fields can only be redirected, not created or removed."

There you find many good articles:

http://www.magnetic-shield.com/faqs-all-about-shielding.html

I hope you are not offended by some real science. You may call me troll, but you should read good science. It might help you to avoid years of useless work. Sorry for my trolling. I may look like an attack, but my intention is charitable.

I always hope for good arguments against well known science. But since I read the OU Forums I only have seen childish misconceptions. And the reason for this stupidity is because the "inventors" have not read the most simple science books or articles. One has to know what is allready known before going beyond.

Greetings, Conrad

Well, Conrad, I've been there may years ago. But the simple matter of truth is that there's more to it, things beyond the standard teachings and simplifications for economical reasons.


You can shield a magnet with an other magnet in repulsion mode, that will no longer attract it. A combination of both can nullify that force. And that goes for both sides of the shield, independently. Then there are also diamagnetics, some new nanotube materials with cpmpetitive strengths may be soon available.


Yes, what goes in must come out, however, there may be a way to sneak out.

Let me just remind everyone that for more then 100 years those who have learned "good science" have not come up with anything new to replace fossil fuel.

It's also a shame that the established "good science" can't even explain electricity, gravity or magnetism after studying it for more then a century.

It continues to fascinate me how those who claim "good science" can keep their head up so high even if they fail to explain the above three effects.

I just don't get it!... could it be they want us to be like them so we can also fail?

Yes, you are right "good science" does not know most of the world, but that is not a secret and every "good scientist" knows the very narrow limits.

But have you ever seen a good answer to your big questions in any of the OU forums or in any of the OU books and articles?

I have nothing against looking for new answers, but please do not announce OU or anything new before you really have it. The so called "inventors" in the OU forums always claim something without delivering anything useful. The only things I ever saw were unsubstantiated claims and most of them were pretty stupid, fodder for wishful thinkers.

So for once please deliver or be humble enough to admit that you have no answer either. I really do not like claims which are not supported by facts. Words cause warm air or take up space in a useless post but never generate energy.

You may wish, dream, hope or believe whatever you like. But all this is useless without facts. Please do not mix dreams and facts. The result is nonsense.

I have to say, trough the various failures of me and others I have learnt much more than from the textbooks. I agree, none should sell (figuratively or literalry) a theory as a working prototype.


It is true that there is real junk science in this field. The whishful thinking followers are naive and have to learn their lesson.


But the fact that the deceivers lie does not automaticly mean everything else is true, such as the statement "there is no free lunch". The whole universe is one free lunch, waiting for being harvested.

thanks for an honest reply.

We are on the same page. I also dislike all the BS claims going around and try to avoid getting involved in such things. Much of my research are my own ideas. So I can only talk about my own experiments and feel over the years I've tried to do the best of my ability to build and test ideas and devices I put forward with measurement data.
If I make a claim that becomes proven wrong I do admit my error and correct the details provided through video or forum topic.

Have a look at the my newest device I've built and presently testing at this time: https://www.youtube.com/watch?v=oUlDMY1iE5A

@Luc,

I think that you have to take time into consideration. If you want a self turning machine, you have to do "work", to apply "force" is not enough. Force has to be applied longer than zero seconds in order to do work (something useful).


========= this post is wrong from here on =============

work = force * time      https://en.wikipedia.org/wiki/Work_(physics)

So, here comes my reasoning (why your measurement is inclomplete and why therefore your conclusion is wrong):

Yes, there is about 500 gramms force in the linear direction (lets call it fl)
Yes, there is about 300 gramms force in the rotary direction (lets call it fr)

But one has to know how long ("time") each "force" has to be applied in order to do the neccesary "work". "Work" is what has to be compared.

I have not figured out yet how you could incorpoarte a "time" measurement in your (very nicely crafted) machine.

One has to find:

tl = time neccesary to do the linear movement
tr = time necessary to do the roation

And then you can ask the real question (how much "work one needs to do" for each of the two movements, lets call it wl and wr)

Is             wl = fl * tl             smaller, equal or larger than         wr = fr * tr             ?

Greetings, Conrad

P.S.: Force is nice but you have to apply it for some time in order to do useful work! (Basic physics as tought in high school. But may be the oil industry has bought all schools and this standard science could be wrong. Or I am a troll paid by the men in black.)

I think you can exchange Time by Distance.


Whether you move it slowly or fast, it doesn't matter if the distance is the same. 1 bucket of water, brought from A to B, that is work, without a boss behind your back, bothering you, not to make lunch break of course.

======= this post is wrong ===========

Sorry, you can not exchange distance and time. This is the error done by Luc in his video (said in other words).

It is very important how much time is needed to move something over a certain distance. Try it yourself. You need much more work (please do not confuse work with force) to move a one kilo stone ten meters in one second than to move a one kilo stone only one meter in a second. You need exactly ten times more work. And to move one kilo over ten meters in one second of course also needs a bigger force than to move one kilo only over one meter in one second. The crucial point is the "one second". Longer or shorter distance in the same amount of time.

You can do with the same force of 1 kilo:

- one kilo over one meter in one second, the work is f * 1 second = 1 * 1 = 1
- one kilo over ten meters in ten seconds, the work is f * 10 seconds = 1 * 10 = 10

Or you can have f1 = 1 kilo and f2 = 10 kilo then:

- the work to move one kilo over one meter in one second is 1 * 1 = 1 (f1 * 1 second)
- the work to move one kilo over ten meters in one second is 10 * 1 = 10 (f2 * 1 second)

You should believe that "work = force * time" and absolutely not "work = force * distance". The time component is all important to compute work.

Time is yuge and total loosers who confuse time and distance or force and work, to say it like Donald Trump.

O.k., I am the total looser, because I confused "work" and "power".

Right, to compute work, the distance is important. It is work = (force * distance). And therfore the work was computed correctly.

But the power was not taken into consideration.

https://en.wikipedia.org/wiki/Power_(physics)

Power is the amount of energy consumed per unit time.

So, to compute the power of each movement (linear or rotary) one has to take time into consideration.

One has to know  (power = work / time), in other words one has to know the time for each movement in order to come up with the neccesary power for each movement. And then the two powers have to be compared.

So, the result of Luc needs a time component in order to do a useful comparison.

I leave my to wrong post above as they are. It allows the OU-believers to make fun of me which will produce OU.
