Joule Thief 101

[MileHigh]

Brad:

You clearly stated that there is no resonant activities in an ICE,and i proved you wrong.
Man up,and except the fact that you were wrong,as that is a fact.

It's completely retarded to go for specific definitions about "resonance" for an ICE after the fact when before that all you did was make a generic statement with no specifics.  You man up and start communicating effectively and with purpose - like a man.  The whole time I have been talking about true resonance and not "motor shop talk" "resonance."  We are talking about electrical circuits.  Man up to that.

Stop this ridiculous "stream of consciousness" nonsense.  LC resonator -> Joule Thief -> ICE -> ICE intake manifold -> Two-stroke engines -> Inertial supercharging  -> Rainbows -> Schumann resonance -> Ping-pong balls -> Beach balls -> Sandy beach -> Gong chanting on the beach, and on and on and on.   It's RIDICULOUS, stay on topic.

Some facts you need to learn before you go making a bigger fool of your self
1- MH dose NOT get to decide what a JT circuit is.
2- MH dose not determine how many different types of resonance there are.
These are facts MH--so suck em up princes.

It's universally understood what a Joule Thief is.  From the very beginning I have been talking about the scientific and engineering definition of resonance.  We are not taking any stream-of-consciousness walks with you, you suck up to that, biatch.

Be real.

Here's a great little video to explain it (resonance in a wine glass) to you.
https://www.youtube.com/watch?v=urYWaHfel6g

@MH Also you stated " And I will repeat again, why should a "resonant transformer" give you better results when by definition you have high currents and increased i-squared-R losses at resonance?  "

If that's series resonance, then yes, there will be higher current. Parallel resonance, then no, impedance will be at it's maximum and current at its minimum. A transformer/inductor cannot achieve resonance by induction alone, but in conjunction with both external and/or internal capacitance, the combined circuit conditions can.

Cheers

In fact the video doesn't explain the mechanism for how a wine glass resonates.  Now does it explain how the resonant frequency is determined.  Now if Brad could show some smarts and explain the process by himself, he would have done that already.  It's probably not an easy Google search, so I think it's almost a foregone conclusion at this point.  He couldn't explain the resonance mechanism for a child on a swing so he is shooting blanks at this point.

Yes about the series vs. parallel resonance.  If it is indeed parallel resonance, then something is acting like an AC open circuit at resonance.  It's even harder to imagine how something acting like an open circuit can "improve efficiency."

I will tell you why I said that.  The first of several statements said something like "An ICE is in resonance."

My actual first mention of an ICE
Quote post 510 :I dont think you grasp the reasoning behind resonance. The reasoning being much the same to that of having the timing correct in an ICE engine-done for best performance.
No where did i mention resonant systems in ICEs at this time.

Your next post- quote post 512:

Adjusting the timing of an ICE has absolutely nothing to do with resonance and there is no connection at all.

Like i clearly said, having the timing correct is !!like!! achieving resonance--both systems must be timed correctly in order to gain the maximum amplitude of power. Take the simple LC tank circuit,where you apply small pulses at the right time in order to gain maximum current and voltage amplitude through that tank circuit. That pulse of energy must be injected into that tank at the correct time in order to gain the maximum amplitudes.The same applies to the ignition timing of an ICE. That energy must be released at the correct time in order to gain the maximum power from the ICE,and that is done by igniting the fuel/air mix at the correct time.

You then said in post 513-quote:

No, an ICE doesn't resonate in any way, shape or form whatsoever.

So here you converted my description of how the ignition timing being correct being much the same as having the correct timing of the input energy pulse into an inductor in order to give rise to a resonant state-->into an ICE dose not resonate in any way,shape or form.
I then went on to show you the various resonant systems that exist in an ICE engine,so as you could learn from your mistake.

Re Quote: The first of several statements said something like "An ICE is in resonance
So no-once again you have tried to misdirect in order to save your ass,as it was you that made the statement about ICE's and resonance first--not me. But because you insisted on there being no resonance what so ever in an ICE,i had to set you straight on that--and i did.

What do you think I am going to do - I am going to take that at FACE VALUE and assume that you are saying that a whole gasoline engine operates in resonance.

Well you bought that ICE and resonance thing on your self,so i gave you several examples of resonant systems in an ICE that both increase the power output,and also the efficiency of the ICE.

And for what you are saying now, it's like talking about a bicycle and saying it is a resonant system and when somebody challenges you, you then post a picture of a bell on the handlebars and say, "See, a bicycle operates in resonance - look at the bell!"  That's retarded.

Whats retarded is the fact that you are now trying to justify your mistake,and incorrect statement.
It is very funny that you your self are the one that bought up the resonant thing with ICE's,and in the above quote,you are now trying to say that it was me,when we can clearly see in the thread history that it was you lol. There is also the fact that your above statement is stupid,as a bell has nothing to do with the performance of the bike,where as the resonant systems that exist in ICE's are there to increase the overall performance of the ICE.
By the way,the bell would add drag,and decrease the overall efficiency of the bike

Your lack of use of language or your abuse of language is ridiculous sometimes.

It's funny you should say that MH,as if we go back and read what actually was said,it turns out that you have an uncanny knack for changing things around to suit your need's. And when that fails,you then try to say it was some one else that said such thing's--even though it's all written in this thread lol. I said that the ignition timing being correct on an ICE,is much the same as a system in resonance--where the energy pulse timing is critical in both to achieve the best result's. Then you decided to switch that to--there is no resonance in an ICE
So once again,by showing several resonant systems in an ICE that increases the engines performance,and proving you wrong,you then do the old switcharoony,and try and say it was all my fault you got it wrong--and it's all on this thread lol.

And the fact still remains that we are not talking about an ICE and none of what you are saying about an ICE meets the scientific definition of resonance.

Lol-here we go again.
MH,everything i showed in regards to resonant systems in an ICE meets every scientific definition of resonant systems described. But be my guest at showing everyone here that im wrong--along with everyone else that provided the science behind those resonant systems in the links i provided.

How does a wine glass resonate?

By receiving pulses of energy at the correct !time!<--time MH) at it's natural resonant frequency.
These pulses of energy can be either pressure waves,or physical contact taps on the glass it self.When enough energy is stored in the glass,and the molecules of the glass are agitated,the glass then go's into resonance.
Whats your point?.

How is the resonant frequency determined?  Explain that and show that you know what you are talking about.

Of what?
Mechanical,acoustic,or electrical resonance?.
And you say i am no good at explaining things.

How stupid are you going to get MH,, the pistons motions as well as the gas charges are what transfer the resonant forces,, that is a force interaction,, I guess you would say a pulse jet is not resonant because the metal body of the engine does not change,,

We are talking about electrical resonance in the scientific and engineering sense.  We are talking about the real definition of resonance, not "the transfer of resonant forces" as in your quote above which is possibly "shop talk" and does not apply.  If you disagree, explain exactly what you mean by the "transfer of resonant forces" and what is resonating and the particular resonance mechanism.  Put some substance behind your words.

There are also many true mechanical examples of resonance.  You know like what Napoleon said about soldiers breaking step when crossing a bridge?

So MH,, How does a wine glass resonate?  what you can not answer the question??

Let's see if Brad can answer the question and show some smarts, show that he actually understands what resonance is for real.  After all, he is the all-over-the-map resonance man.

BULL SHIT ! Resonance is to Oscillate a petrol engine is an explosive device !  nothing to do with resonance !

Oh dear.

Wonder if MH will set you straight on this--Mmm
Probably not,as you are disagreeing with me,he would see you as an ally.
So right or wrong,he wont set you straight.
But your way out to lunch.
