Joule Thief 101

[tinman]

Brad:



The rest of that posting is just plain silly as far as I am concerned.  It's a mish-mash rehash that has no value.

MileHigh

I already told you that as far as I am concerned that whatever it is that you are holding back may actually be nonsensical.

As you have said MH--it's time to use your own brain,and not be expected to be spoon fed.

I also told you that we are talking about a supposed "Joule Thief in resonance" and the true scientific and engineering definition of resonance.

So post your definition of true scientific and engineering resonance.
What do you have to gain from holding back information you deem to be of great importance?.

The simple fact is that I don't care about the issue of determining the top speed of the car and any possible missing piece of information.  I really do not care, it has nothing to do with the thread.

But it was you that bought this (nothing to do with the thread)into the thread

It was just a "learning tool" for you so that you could see that you could answer questions with concepts only, and not with specifics.

MH
Can you not see what you yourself is writing?. Look at what your saying.
All that definition does is describe an attribute of resonance.  It has very limited scope.  It doesn't even touch what the two wine glass questions are all about.  So, to answer those two questions you have to go deeper and truly understand what resonance is and how it works for the wine glass.

You want the specifics understanding of resonance,but described by using non specific concept's.

If that was your learning tool MH,then you are teaching the incorrect.
Why is anyone going to listen to what you have to say,after they have read this thread.

It's me bending over ass-backwards in an attempt to communicate with you.

Rubbish MH
You have done nothing but try to discredit and belittle me. Time and time again,you have disagreed with what i have said-just for the sake of doing so. Never have i seen such a display of willful ignorance from some one who once held my respect. Time after time i have had to spend my own time correcting your incorrect statements toward me.
The resonant systems in an ICE
The operation of the cool joule circuit
The !determining the top speed of a car! saga-->which i still cannot believe you do not know what you missed--->you are proclaiming to be the teacher here-remember?.
The operation of a JT at low voltage-which you did not even try and attempt to work out.

There are those here that wish to go further than the standard model-to do all that we can do-and be all that we can be. But you just bring nothing but disruption--that is all you have done to date on this thread alone. Im not even going to start to mention other threads,where you have done the same thing.

I (and many others here) have shown you your mistakes,and yet you still insist it is the rest of us that do not know what we are talking about.
How sure are you that there is nothing special in todays 2 stroke ICE's. How well do you know thermodynamics--> not the laws based around systems of the past,but of those that exist today-those like the two stroke ICE that have perfected resonant systems that have increased there mechanical power output by huge amounts.

I am going to leave you with this to contemplate.
For this we will go back 20 years,and look at the 2 stroke ICE of that era.
Lets say the efficiency of the ICE back then was 32%-meaning 32% mechanical HP energy out,and the remaining 68% percent as waste heat energy output. This as you know is in relation to the contained energy within the fuel supplied to the ICE,and we have accounted for 100% of that energy contained within the relative fuel amount.

Now,!!try! and leave the current laws out of this,and think hard about what i am about to say/ask of you.
Lets now move to this date,and look at the 2 stroke ICE's we have this day,and there use of resonant systems to increase both efficiency and output power.
How is it that some high end 2 stroke engines of today can produce far more HP,and also more waste heat,but still use the same amount and grade of fuel that our 20 year old predecessor did.
How is it that we accounted for all the energy input in our older design 2 stroke engine,in the way of HP and waste heat output,and yet todays engines produce far more HP and waste heat output,for the same energy input.
Where has all this extra energy come from in the new ICEs,when we had already accounted for 100% energy conversion in the ICEs of 20 years ago?.

We can discount wasted/unburnt fuel from the earlier ICEs,as even back then,the high end engines lost very little in the way of unburnt fuel. So this small amount(less than 5% of todays )of unburnt wasted fuel can in no way account for such high power increases.
We can also eliminate any major changes in the ICE unit alone,as even 20 years ago,we were already using things like chrome bores,high quality ring's,high compression ratio's and extremely well balanced cranks.
The only real advancements has been in the resonant chambers/resonant systems incorporated in those ICEs.

To add to this,go try and find any test data that refers to the questions above about todays 2 stroke ICEs. Data that shows us that the energy conversion from fuel in to HP and waste heat out,is still only a 100% conversion.

I have not included vibrational and sound wave energy in the above,but they must also be included in the output energy calculations--something overlooked quite often,but small in relation to the HP and heat output.

There is absolutely no conflict in what I am saying.  So you are either trash talking again or you have to work on your English comprehension skills.

You still bring up the Cool Joule circuit but it has already been discussed.  "Miller capacitance" does not explain it.  You have to do a timing diagram and really explain it, not do a "drive by" fake explanation.  Like I told you before, you would be sliced to pieces on any serious electronics enthusiast forum.  You have to teach yourself to effectively communicate a concept.

I can't comment on the evolution in the efficiency of two-stroke engines because I know next to nothing about that and I never claimed I knew anything about it.  It's not the subject of this thread.  We are talking about true resonance and a hypothetical Joule Thief in resonance.

You can rant and rave and stomp your feet and turn blue and trash talk and it won't make a single difference.  Give it your best shot at the wine glass questions and to do that you should do some research and stop and think about it and come up with the proper answers.  Because right now you are incapable of answering the two questions about the wine glass.  Instead of useless trash talk that just makes you look very ugly, you should be embracing the challenge.

MH can't go back on this [in his world]
he called you a clueless poser and many other things regarding you stance [and knowledge ] on an ICE.

which to all who can read and comprehend the written word has been shown quite clearly in your Harvest
of SOME of his quotes.

but he is sliding the goal posts in every imaginable Sqwirmy way to deny you your Truth and continue his assault
on you [making himself some victim of ignorance]

the stomach turns.
he will never apologize ,he would chew his own nose off to spite his face...

You however Brad have apologized many times here ,and I know they were not easy times.

MH has taught us a great deal here !




 

[MileHigh]

You are just a hapless biased groupie Chet.

[ramset]

let your audience read post 831 MH

I completely understand your position ,I have seen many children deny the words that just came out of their
mouth .

but here you attack a man ! well actually ,many men .

you have bitten off a very big piece of your "Karma" and it will choke you unless you
spit it out and do the right thing.

rechewing it hoping it will swallow is a very bad idea ..

and thinking your readers will swallow it for you ??
even worse !

apologize

I am certain a man like Brad will do what he does and move past that .
