Totally unsatisfied with my new cut down MOT coils, I have been able to get okish acceleration from about 1,100rpm and up, it will jump about 5-7 rpm a reading at best (oh, and a very very tiny gap is required) but not as good as either of my previous coils so I think I'll go back to them. (that's with both in series, either alone is worse)

Why did it work so well for Thane when it works so poorlt for me? Or perhaps the question is why did my previous MOT core work so well for me when Thane had some issues with MOT's until he cut them down?

Rather than try and do experiments tonight I'm going to try and get everything working as well as possible for the morning, after I get the effect decently with some stator selection I'll attempt some of those experiments including hopefully finally for real the isolation test.

My current results are such that if it wasn't for some of the tests Thane and others have done I'd just put it down to reduction of vibration/cogging torque on shorting, it does become quieter.

So far to me more turns always looks better.

hmmm, I have a thought!
I wonder if you could take a high current coil (at least a low voltage one) and short it, not get the effect, and then put lots of such coils on the same core and short them all and get the effect?
Might work, might not.

Continuing on from that thought a bit more, the coils should really resemble HV coils, the same gauge of wire should probably be used and just as many turns only spread out over 10 or 20 individual coils, or one HV coil with lots of tap points. (My monster coil has too many turns between taps and the new one is too crappy)
Another thought is that multi core wire or litz wire may even be used possibly.

From an aetheric POV I'm not sure if that would be as good as a HV coil or not.

And not continuing on from that, I have verified that my 'poor but it works' coil will decelerate of you short the 2 closest points together, so if I short the start with the first tap point it will slow it, and the first tap point to the second and so on, now I just need to figure a way to connect about 8 wires together at the same time, either that or do it the slow way, but currently I don't probably have enough leads for the slow way.

Thanks for the welcome.

So the system is less than 30% efficient, so the electrical system has COP=0.3?
In what part of the system has a COP>1 (COP=70?, 7000% remember ) been observed?

Is it observed that torque decreases when RPM increases? hence Power = torque * rpm.

I am interested in this project, but this discussion is too long. Maybe progress and discussion should be seperated, by placing all progress and data on a seperate web page? (No rudeness intended)

Woohoo!

Ok, now how about this!

I theorized above that the voltage is not the thing but rather the number of turn in series or parallel.
And that if you had enough coils which above I called high current but in reality are just low power (volts and amps) that you would get the effect.  Actually high current would be valid as long as you only shorted one of them and had decent cooling.

Anyway I hoped to try it with my failed multitap HV coil, but I was going to have to short out every tap point with the one either side, it was going to use up all my leads and take a bit longer than I like to test with (you want to disconnect, reconnect again and again to see the rise and fall isn't chance).

But above I did point out another conclusion of this idea, that you could just maybe use a multistrand wire, sure the coils would not be insulated from one another but why would that really matter?

Well I just happened to have a length of a really nice fat multistrand wire (to clarify each strand is really think which is probably important to aether velocity), not sure how many wires are in it but it's gotta be over 100, maybe 200 or 300 (I have not even looked yet to see if it says).

I wound that over the free end of my monster coil core (it has a really really long tail!) about 26 turns (x ?00 strands) and put that as close to the (now 1x6 magnet)  rotor and I got it up to somewhere above 2,500 rpm I think and once the speed reading on the tach stabilized I shorted the fat multistrand coil with my fingers and the speed rose! I disconnected and it dropped, I reconnected and it rose, I disconnected and it dropped.

It did pretty well!

The inductance of the coil is so low there is no spark when you break the circuit, I checked it out and the voltage was just 0.86v but the current (shorted through my multimeter since Idon't have a clamp meter) is an impressive (unless you count all the strands) 5A.

I am going to try and wind a coil made of the same number of turns of the fattest (single strand) conductors I can get and verify that that does not work, hopefully it would have the same resistance and inductance and current but a deceleration effect.

This sure seemed like the same effect, but the coil was MUCH MUCH MUCH easier to wind!

This verifies why some such as Don Smith and Kipper coil dude stress the use of wire like this, lots of very high speed aether, oh and to a lesser extent Steve Marks TPU too.

Thane, get thee behind to Ye Olde Wire Emporium ASAP!

If you use the same amount of copper in both coils, then that would be a very interesting result.

To you the aether might as well be bubblegum, to me the aether might as well have been a turd so your cognitive dissonance should be a lot less than mine was.

Would have made the whole Photoshop idea far less appealing for sure...
