I wonder if this is Rose's sibling. the irrationality, the arrogance and the unnecessary rudeness certainly match. In the meantime it's diverted Dieter's thread.

There is nothing wrong with making assertions as long as they don't contradict what is known to be true already. If one makes a claim or assertion that does contradict something we think we know, that's fine too.... as long as _evidence_ is presented to support the claim. Real evidence, checkable, repeatable evidence. Once the evidence for a claim is presented, that evidence can be examined for validity and relevance, by reasoned discussion, experimental research and demonstrations, and references to checkable outside sources.

If one presents no evidence, but instead relies on ad-hominem abuse and more contradictory claims.... then they are fair targets for harsh criticism.

(Did you know that I have a herd of winged pigs in my backyard? They are invisible, silent and they don't smell badly, so I'm not going to show you an image of them, but I assure you that they are there (if they haven't flown away.) Now... prove me wrong, or you must be an idiot no-nothing.)

See what I mean?

I'd love to see a discussion between Atommix and Turbo. That would be a real hoot.

(snip)
Maybe you read it again so you understand you are in a place where time itself does not exist instead of dragging oscilloscopes and frequency counters to this place....
Becuse they are useless if there is no time then they will read 0 and i think you are a fool for not understanding that.
I was clear about what i ment.

By golly.... I do believe you are right!

@Dieter

Do you mean, for instance can one connect a (high amperage availability), 12 volt lead acid battery in series
with a (high voltage source) Vandegraff generator and get giant power ?

Current flows in loops (eventually).

Makes me wonder, has any body ever measured the resistance across their Vandegraff (not running) ?

I have, it's an open circuit. Sometimes the belt can become slightly conductive after long running, from carbonizing the  materials, or from moisture adsorption. Then, if the test voltage is high enough, like from a "hi-pot" tester, you may be able to measure some finite conductance. But since most VDGs don't make physical contact from the pickup combs to the belt, you need the HV test even to see this small conductance. An ordinary DMM will read infinite resistance, or zero conductance.

That's a good question. I don't know if the VDG, running, will allow the complete circuit from the 12 volt battery. I'd do the experiment instantly, but I don't have my VDGs available at the moment. Giant power? No, the most you could get would be the power from the VDG plus the power from the 12 volt battery. You will get (Vvdg x Avdg) + (Vbatt x Abatt) = Ptotal.  I really don't think you will get (Vtotal x Atotal) = Ptotal.

I have a question: Do the voltage and the current for a cetrain load have to come from the same source?

Or could I, example given, use two independent sources like photopholtaic and wind or whatever, then go out of phase with each one by -90 resp. +90 degrees with a cap and a coil, then ac- sync this so in none of them is actally both (v+a) present, then simply but these together , maybe trough some diodes, to get a complete, working source of V+A ?

I have wondered much the same. What would happen if you were to pulse a transformer primary with high current DC and smack that in the rear with an immediate pulse of HV AC, in effect giving it a single duration pulse?

Can't combine AC & DC together? Try telling that to this guy.

That whole thread is an interesting read.

Just who said that, please? But first... how do you define AC, and how DC?

Since AC involves current reversals, and DC does not..... well, I think you can see where this is going.

I was just asking because several projects mentioned it, eg. current from the ground an voltage from the sky, wasn't that tariel guy doing something like that? And it was mentioned in that 4 mb FE collection pdf from this other russian guy.


If we compare electricity to a river, voltage be the speed of flow, curtent the size, it would be absurd to say it flows down that hill overthere but it has never been there.

Sorry, but you are not even close.  The difference in height of the river from some starting point A to some ending point B would be like the voltage.  Voltage = height.   The amount of water flow in cubic meters per second would be be like the current.  The physical river itself would be like a large resistor.

That's right. Like charges repel, and this is the _source_ of what we call voltage. Pack a bunch of like charges together and they will repel with more force the more charges you pack in there. This is voltage.  Provide a path for the charges to relieve this pressure, and they will flow along the path until the charge pressure is equal everywhere. This flow of charge is current.  Charge is carried by free electrons, which carry the unit negative charge, and also by "holes" which are places where an electron "should" be in a molecular lattice, as in semiconductors. "Holes" are positively charged, electrons negatively charged. Because of the naming convention assigned originally by Benjamin Franklin, the electrons are called negative. This is somewhat unfortunate, because what we call "conventional" current is taken to flow from positive voltage regions to more negative regions... but the actual flow of electron charges is in the other direction, from the packed "negative" voltage region full of electrons and depleted of holes, over to the more positive voltage region, which is deficient in electrons and has a surfeit of "holes". This was not known in Franklin's time, though, and by the time the electron was actually characterized by several researchers like JJ Thomson and Robert Millikan in the years around the turn of the 20th century, we were stuck with Franklin's "negative" terminology.

"I am dead serious you do not even understand 0.0000000001% of this whole thing."

(Quoted from Turbo's PM) 

Wow! 

Check out the sig. digits here.  I wonder how this was calculated?  10 places...not 9...not 6...not 3...but 10.

 I
f it were me, I would have went 11 places out, just to be sure I got my point across.  12, of course, would have been overkill, but 11 would have done the job well.

Yeah, precision is important. Well, I guess it's time... or maybe NO time... to go out and feed my herd of invisible pigs. There are at least ten thousand of them in the back yard. I'm not sure how many, really. Have you ever tried to count invisible pigs? It's not easy. But it beats making Ainslie debunk videos, there's no percentage in those.

MileHigh, old sceptic I was starting to miss you. Not even close? Well, the speed of flow is determined by the height diffrence you mentioned, so you agree with me.


As for the cubic meter per second, that my friend, would be Watt and not Ampere, as you said so eloquently.  :P

No: the fluid flow rate is equivalent to electric current.  The applied or lost power is the product of force and flow rate.  The force is the result of the height change, the mass and the acceleration due to gravity.
