Building the sickest ® VAWT ever. Brilliant minds unite please!!

the magnets do not show any signs of heat buildup what so ever.

NO that is not true. I can see some of heat transfer.

But by the time they have rotated it all has cooled down.


NOW this is ! BIG worry for me.

Because if we go full scale like we of course need to. Then there is no more opportunity for the many many things that allowed for these results to propagate to the large scale tests.

I am aware, I will admit that I sometimes did not see it coming.

Let us just just hold on till I am happy with the PMA.

 

[brandnewb]

and in case yo are wondering why it is soo damned cold there?

well that is because I stopped heating my gym.

So what ever the temp outside is. some of it will be matched by the amount we are leaking.

 

[brandnewb]

read them and wheep.



8.4 amps at 9.8 V



82 watts!!!!

not too shabby for a mere 5x litz 0.4mm wire at 35-70-35 coil now is it?

I just so long to be stood corrected!!


Until such time I am moving forward. Going full scale.

 

[justgary]

82 watts!!!!

Would that it were so simple. The RMS (DC equivalent) value of a sinusoidal AC waveform is 70.7% of half of the peak-to-peak voltage. This is because you also have parts of your waveform that are much less than the peak. So, half of 9.8V is 4.9V, and the RMS voltage is 4.9*0.707=3.5V.

Now the power generated is 3.5V*8.4A=29W. Actually less since you measured the open circuit voltage, not the voltage while under load.

[brandnewb]

if you are here for the party then why are you such a party pooper?

hahahaha

nah brother. keep it coming. ok less than 29 watts it is then. I will read up some more but even so.

I think this base line coil is not disappointing is it?

 

[brandnewb]

actually it is disappointing. when I extrapolate in my mind I get no where near the gazillion Terra watts that is the goal

 

[brandnewb]

so disappointing that I went and checked on how to calculate dc rms based on ac peak voltage in a single phase setting and came to
9.8 vACpeak = vDCrms * SQRT(2)
which works out to 6.92 vDCrms
which in turn works out to a wattage of 58.2 when multiplying by 8.4 amps.
Anyway since this was in an open circuit setting I am going to potentially sacrifice one of my lifep04 cells and hook it up directly to the base line coil and measure both the amps and the vDC at the same time to get things cleared up regarding this.

I fully believe now that pulse charging is not a problem based on the below research paper so all I need is a simple rectifier.

(this study reviews several earlier researches regarding this and no need to translate from Dutch as it is in English)

Should the base line coil be happy to provide too much power I can add another cell in series and just keep adding cells in series one by one until I get a better understanding of what this coil can do.

But your peak isn't 9.8v, your peak-to-peak is 9.8v. You still need to divide by two.

argg. I both love it it when my superiors are correct all(most off) the time(s) else risk me running after my own tail all the time.

But also hate it as it is slowing me down/ or even preventing me to get to where I want to get.

But this is just a joke of sorts.

I really respect the pushback otherwise we end up with garbage for a whole new generation of unsuspecting readers to just blindly follow.

Anyway Gary, I think you know more about how this stuff works that the internet does because when I started measuing your statment with the setup below I could do not nothing else than flame and admit you are correct.!!
Now do you see how close the word admit is to another one that conveys my emotions? hahah

damn{insert characters}....

My lord I hate infuencers!

I'll ask again! . How does one protect their offspring these days from this wildfire of nonsense?

Anyway back to the matter at hand.



Here we have the most recent configuration preparations for what I think in the meantime is a sane way of tackling this problem.

I have now stored into the freezer the simple method I proposed earlier. Rest assured it will thaw again at one point or another. I guess we all know by know that ideas will mostly be re entertained if not properly laid to rest. Just for the sake of being able to let things go.

Was it easy for me to admit that my wild ideas were misguided?
...
..
No of course not. I hated that. I had hoped to be the next genius out there.
..

did that determine me to understand that that is is only a bonus which we should not expect and that the goal should remain the goal?
(without a second thought) of course. lets get this on. where ever this leads us. I will take my pride from the fact that I was even able to get things done with the help of so many of you.

What we have here is a setup that can measure many data points in a single run. With the exception of the data points to be taken with an open circuit.

Now the start point is a Lifep04 cell single cell, But it is easy enough to add to it in series step by step.

Please scrutinize the following data points I think are relevant for the creation of solid charts.

If this is going to be the new standard then I am a bit sad.

Boy I wanted it to be just simple!!! even though I knew it was going to be HARD. I just once again thought that maybe with a little weird thinking perhaps things could become less difficult.

Hahha. well at least I keep trying.

Here goes

* motor Hz
* (open circuit) (Hz) while at vAC (below)
* (open circuit) vAC
* (closed circuit) vDV (after rectification)
* (closed circuit) aDC (after rectification)
* Coil temp (celsuis)

Now I already know I forgot one or 2. Please help me out here.

So I thought and go with 15 coil legs per unit rather than more as to make it more manageable to actually have them play nice while in service.

I do think you are going to have to take my word for it else risk to stand challenged by me

Now given my reserves have just recently been recharged again. I would advice to only do so if one has a good point.

You see that I today I found a new way of measure coil lengths to be able to wind them in larger strings.

Well here we go




this is a 35-(13 x 70) - 35 coil.

Ok sure I will have to admit that this casting is not the best. But even so it has regenerated my reserves again.

Ready and waiting. Poised to strike!!

 

[brandnewb]

ohh and of course I have a new hot topic.

The larger the resistance is in a wire. the more an iron filled core will do in terms of field enhancement.

this is my bold claim. And I am sticking to it for the time being.

 

[brandnewb]

I respect that it is a jungle in the picture.

But that is because I am not a realtor trying to sell a home.

I am a guy that tries to convey what is going on here.

Now I do welcome anyone that would like to see some things changed. like make it more obvious which wire is going where and stuff like that.

Other than that. This is the best I can do, for now until more education.

And still I hope it will be read them and cry in joy.
