@bolt : i have a feeling you keep saying the same thing and most of the people keep not understanding it over and over again. Maybe if you could try to explain it differently.
Try do design a mathematic circuit. Just take a desider wire, give some coil size ( turns.. length...) calculate for that coil and specific RPM the cap size, draw in paint the circuit for it and post it here. I bet there are a lot more people who can copy paste then think deeply enough.
Thanks if you consider doing this.

Neptune,  sorry no,  not in my textbook.
At resonance, both in series and in parallel, Xc and XL cancel each other out resulting in pure resistance.
In pure resistance, there is no phase shift between "i"and "v".

Bolt,  so when you say VSWR = infinite, that means that all the energy is reflected back as being in an open circuit/transmittionline  (sorry, thinking as a radio ham here), right?

Correct i know the HAMS here will understand this i speak HAM for a moment. When the VSWR is 1:1 all the power is conveyed along the coax as a 50 ohm load and a 100 watt dummy load will be pretty much 100 watts of pure resistive power. This is why HAMS are always tuning and playing with the antenna to make sure all the power from the PA stage is fully absorbed by the antenna and the antenna will soak up pretty much all of this power to give a max ERP we call this Resonance tuned.

If i  detune the antenna say  VSWR 2:1 then 50% of what im putting out is being returned as a Standing Wave Vector. Not only this but HAMS know if you run a rig over 2:1 you are most likely to destroy the power FETs. (unless it has VSWR protection)  This is not because of excess heat that normally does the damage is because the voltage increases dramatically from the 12v supply there could be as much as 90v pp on the Pi Tank circuit.

Now lets take this to extremes!

Tune the rig so the VSWR is infinity. Change the PA so it can handle 2000v then design the antenna that can support 1000 amps of displacement ground current using 1ft wide copper sheeting. Now you have a reactive antenna which has capacitance between the earth and the driven element but this time there is NO transverse wave radiated its now pure longitudinal scalar operation. This is now a  2 MVAR's scalar transmitter powered by 100 watt driver.   The ambient responds  with 2 megawatts of magnetic flux field and this is how HARRP is used to trigger earthquakes. Make it a 100,000 Megawatt scalar system then you can cause some shit:)



Dealing with about 120Hz, then one wavelength would be around 2500Km so when aiming for VSWR = infinite, i would need to be on a quarter wavelength = 625Km.

Having coils of 2x 300 turns on a sewing bobin = about 60 meters, i am way off, right?

So i am lacking inductance plenty, so need to add inductance, right?

You need lots of inductance if you only have small self capacitance or combination of the two to give the required phase shift to desired  90 degrees.

Sorry to push,  but there is so much confusion here, so any clear explanation would be welcome.

I am puzzled by the 900 mA because Romero's no load speed cannot be more than 1500 RPM judging from the video and with those components, the 'normal' current should not be more than 500 to 600mA. I think but I could be wrong. So, this extra current could be used to periodically slow down the rotor at resonance to pick up the most magnetic flux? The way it could be done is to bias some of the pickup coils to reverse(repel) the normal forward direction of the rotor. Just my guess.

Hi chrisC,

I have answered to you here but surely there were so many posts you may have not noticed:
http://www.overunity.com/index.php?topic=3842.msg292308#msg292308

Regarding your thoughts on the generator coils biasing I do not think it is involved here. Why would you furnish precious input energy to work against the main forward direction?

Gyula

bolt,

Are you a HAM, and/or have radio electronics background?

Hi all

@ david

Thank's for this opening, i must admit that it was necessary, because after so much tests with trial and error, and  especially also because Romero plays a not really understandable party.

And because (thank's to Wattsup and his really good work on analysing image frame after frame)  i have to accept that in the 3 video the BLACK AND RED WIRE are always present. What are they for i don't know. But they are there and of course this is not motivating at all without a really clear explanation from Romero.

By really clear , i mean exact connection of each of those wires in the 3 respectiv video.

So in video 1 what does mean  "not directly " connection to battery
     in video 2 how exactly are the wires connected to the bottom coil ( or other ) without any doubt.
     in video 3 those black and red wires seems to go upwards ( at  52 )  is it right and to what are they connected to .

I don't know what to think of all this

Be all sure that  i consider me as an apprentice in all this things and i can only be happy to participate. but the actual situation is not agreable at all , for my motivation of going on this experiment and as we can see also for the whole comunity

i dare to ask you Romero and really sorry to have to do, and  perhaps i will be banned here but i have to know



  Can it be really  true ,As you already stated when you first quit , that you fake it by adding a hidden  power supply or other mean  to power the muller Dynamo in your videos ?  And in the improbable "yes " Why ??




So David thank a lot for your info and as you can see good or not good anyway i will learn something from all this stuff

Here the pix of the david's proposal as i see it , it works very fine with my 30 magnet wheel (NSNSNS...as per lecture  Romero  video  ) adjacent magnets arround  fit on a HDD.

sorry for this post but absolutely needed

Good luck at all

Laurent
