PDi Regenerative Acceleration and BiTT Principles

[JulienVictor]

Dear

I would like to build a larger BITT, means one that support 100 VA. Do you have an idea if I could use steelwire for lower frequencies (50Hz)?
I guess th efficiency would be poor, but I would compare it to a conventenial design made with same wire.

Here is the latest bitt I constructed, used ferrite to elim eddy losses and drove it with only 50vac to keep below saturation and keep input current wave pure sine.  Used borrowed 2ch scope with phase and power calculated to take data and found only lossy transfo action.  Was very disappointed as I had seen what appeared to be current drop on primary when load applied to sec when using cheap meter across shunt on input of previous devices that turned out to be false when measured with scope.  Distortion a in sign wave fool these dvms people.  Tried to make sec paths much larger than primary path for best results, not convinced on this one people.

I've just seen this. That's really disapointing. Do you have a shot of the waveform?




You said you made shure to stay under saturation, but didn't Heins say the primary core needs to be close to saturation? (to force the back mmf to the outer core).
A further test may be to use a cap in series with the primary, as I already stated elsewhere, i achieved  some interesting results that way. Just find the right capacitance that will let everything trough, but bring the current +90° out of phase.

Dieter;
At 50vac 60 hz both the current and voltage into the primary were nice clean sign waves.  From what I have read on this device (darn near everything I could find), this test should have shown the Heins effect.  I also tried it with 120vac 60hz but was energy destroyer due to saturation that could be seen in the current waveform of the primary as distortions.  These distortions are what was tricking my digital meter in previous tests.  I did take notes and readings on all the tests but it is in notebook hand written at the moment.  All tests showed under unity.  The rod for core under primary core is .5" ferrite and the primary coil is a wire spool full of 30awg wire.  To me this calls into doubt thane's claims as I should have seen some sign of the effect.  I even tried it at different frequencies on freq generator and could not find any sweet spots showing Heins effect.  Primary current was between 9 to 12 ma at 49vac input from what I recall, 12 being loaded, 9 unloaded.  Phase angle shift towards resistive powerfactor when load applied was seen as well.  I didn't grab any pics of scope screen however as it was sinus at 50vac.  Very disappointed with this one after so many iterations and waits on large ferrite toroids from china.  I even am still waiting on some parts to arrive still but seems kinda pointless now. 
This was not a waste of time however, shows there is something missing from the models for "flux" in my openeion or else some heins effect would have shown.  On to my gabriel/tesla shield transfo experiment it is!

Boots,


so the outer core was a wire spool? I have to say this chanches things significantly! I also made a BiTT with iron wire toroids, the outer one massive, the inner one winded in a 8-winding mode. This device had the worst efficiency I could imagine. Using Ferrite in the primary and iron in the secondary is not promising, the oppisite would make more sense. The permeability of a iron wire spool and a ferrite core is significantly diffrent, maybe more than 10x, so there may be hope .   


Also, unlike many OU concepts, this one did not have NO EFFECT at all, but really altered the behaviour of inductive coupling fundamentally. Not shure if it's OU, but it is something.


.I have also seen vids of people, showing scopes , power factor clearly zero, then hit the load connection switch and the scope remained in that phase angle, only the tip of the voltage came down by maybe 10%. Didn't bookmark, but I've seen it on Youtube..


Well if the gabriel device is going to work (what if not BiTT tech is the principle in your view?), then you don't have to worry anyway, otherwise use the ferrite toroids and give it one more chance.


Probably think about metglas, two pounds ribbon is 33$ on ebay.


If there is free energy, then the lobbies will suppress it, by ruining the inventors. Especially when they use reactive power, which is for free, but needs a lot of investment to be provided by the power plant and grid.
