Over Unity NOT Achieved!!!

Hi Rich,

Thanks for mentioning Page 31 where your alternator circuit setup is shown. This is what I did not recall as a way for extracting power from the alternator.
Have you considered to continue your test with adding further 2 loads to the other two legs of the alternator? for you so far used a single leg tuning. 
Does the current draw of your prime mover change when you switch on the load at one leg of the alternator? 

On Page 32 there is a Note: "be careful with a combination of smaller bulbs (parallel and/or series) as there is a mass radiation parameter that must be taken in consideration using series/parallel connection, some filaments being partially
magnetic will not glow at all even having same ampere loading character (resistance ). Ohms law does not cover this nor other book data.
I wonder if the 1000W bulb was slightly magnetic so that it could explain the lower brightness... 

Also this text from the same page I quote for the frequency change problem at the alternator because the windings with the motor laminated core are inductances whose Q quality factors (their figure of merit) are changing with frequency and for any geometry/size/core type there exists an optimal frequency where the Q is the highest and this frequency is desirable to look for to get the highest circulating resonant current. Here is the text:...That is 1000W must be run with 618W at input at unity PF; same luminance as lightbulb directly connected 220VAC. These experiments were done using 60CPS; as frequency increases so does efficiency. The idea is to series resonate LCR as to make virtual power becoming real manifest within
physical entity of bulb to create a pure current node were voltage drop of bulb is less than 19.8 VAC
So it is wise to change the PM's RPM and always look for a resonance with the cap bank at the alternator side while monitoring its circulating unloaded current to find the biggest current which would mean you have found the sweet frequency where the highest quality factor for your particular alternator inner inductance manifests.  This is possibly NOT corresponding with the original frequency the motor you use as an alternator was manufactured but this should not bother you for the moment.

I think Doug Konzen from the EVGRAY yahoo group made prony break test on an RV setup and he is convinced having OU (maybe Stefan included this results on the Forum) and I can accept Doug's measurements.  I personally have not dealt with such because I do not have a shop where I could store such motors and do experiments, sorry if this disappoints you, for how dare I suggest anything without hands-on experiments...  I have other knowledge in EE and it can help in this area I think and so far I have not said anything wrong on RV for you

Well, a little good news.  I started playing with my o'scope and it reads to 600V.  Not enough time to duplicate my earlier tests and use the o'scope plus DVM but I'll get to it eventually.

Well,  I'm really confused at this point and will need to think abit.  Here are readings from a quick test, no great tuning just something to compare the DVM to the o'scope.

PM: 4.7 amps @ 121VAC

Alternator without load:  398VAC @ 7.5 amps @ 116.2hz

TRUE FULL BEAUTIFUL SINE WAVES

I want to believe and the meters say it is there but this is just out right strange.

Hi Rich, what load do you drive, so you get the 7.5 amps ?
What is the phase angle between voltage and current at the load ?

Hiya hartiberlin,

This is without load, basically shorted and testing across the parallel cap bank.  My caps are on double pole/double throw switches so this is not a residual charge in an unused capaciter but the active capaciters.  My scope is only a single trace and I have no shunts in place.

Oh yeah, the DVM measured 2VAC less than the o'scope.

Now, a theory.  The o'scope and DVM measure peak-to-peak voltages but cannot distinguish non-current carrying pontentials from current carry potentials.  Let's say we have 200amps @ 1VDC with 120VAC potential riding on it, this would show-up as 120VAC on a DC potential but the amp meter would indicate 200 amps with a wattage of 12,000.  This seems to explain exactly what is going on in the videos and why no one can manage a similar load to what the instruments are indicating.  It could very well be possible that due to the three phase set-up, the capaciters changing the phase angle, and the o'scope being basically blind to anything but an outline form that it is combining the residual voltages of the other two phases and super imposing this static charge on the true current carrying voltage sine wave thus making it look like something it is not.   This only way to veryify this would be to remove two of the three coils from the alternator.

This is the only thing that makes sense to me at this time.
