@gmeast.. cant post links coz im on opera mini compression on a phone.are you using lead acid batteries there gmeast.do they have openings that you can open up.theres a very nice way to gauge total power in lead-acid systems.


Presently I'm using the batteries I show on the forums.  They are SLA and/or AGM (Absorbent Glass Matt) and there is no access to the interior. What were you suggesting anyway ... specific gravity?


I'll post the Steven J. Smith link for you:

yes i was going to suggest specific gravity or chemical test or conductivity measurement for varification of unchangeing electrolyte concentration post-run.chek out the 'self-charging electric car'thread where i give details for a spot chemical test for sulfuric acid gauging in the bats.if you want total absolute varification of overunity to yourself or to the public this is best way gmeast,to use lead-acid open type cells as the totality of power usage or gain is directly proportional to acid concentration.

I'm not sure this would be definitive in that the batteries are expected to discharge. It's just that they discharge less than would be expected.  I've been very careful to run the Inductive Resistor Heater tests head-to-head with straight-up ohmic loading. It's the comparison of these two tests that are vital.

@gmeast.i see what you mean yes.is your circuit recharging the bats at all? If its straight electric to heat comparison then these electrolyte tests wont do yes.if any circuits are selfchargn bats then its a genius method for total proof.even for sake of improved efficiency proofs.

Just an update:


I'm still going to replace the batteries with a capacitor bank at some point, but the bank will have to be huge just to get a small enough voltage drop on the caps to allow for a a decent test duration ... hopefully 8-hours. If you examine the discharge curve for any capacitor you see it's the inverse of it's charge curve. On discharge, the cap voltage drops very rapidly over time for a given load. So the cap bank must be very big (wide - that is "parallel") if the voltage is to drop only .5VDC to no more than 1VDC over the test duration. As the voltage supply drops much below 24VDC to 25VDC, the performance drops off considerably. Lower voltage also affects the gate driver circuitry.



I'll first build a single 'series' bank for the supply voltage requirement (for 30VDC) and load it as I did during the battery tests ... around 3.2Watts. From this loading I'll be able to determine the rate of discharge of the bank for the particular capacitor specie. It then should be only a matter of arithmetic to scale the 'real' capacitor bank based on the same specie of capacitor. It could take well over 150 capacitor$ to get a sustained 3.2Watt draw for 8-Hours with only a 1VDC(max) voltage drop. It's possible to figure that out now just from the above requirements, but actual data is always best to have.


That's all for now ... only takes money.

Hi Greg,

Here is a useful link for estimating the Farads for the capacitor test: http://www.circuits.dk/calculator_capacitor_discharge.htm

My playing with some numbers brought this: you would need a capacitor bank in roughly 7750 Farad total capacity value and then starting the test from 25V and running it for 8 hours (i.e. for 28800 seconds) the cap bank voltage would drop to 24.5V and if you change this to allow the discharge down to 24V from the initial 25V, then the cap bank would need to have only half of the 7750 F   i.e.  roughly 3824 Farad.   I used Imax=128000 uA discharge current (3.2 W at 25V) and for capacitor ESR I used 0.1 Ohm (you have to consider later the real capacitors ESR value how they calculate in the series and parallel assembly and recalculate the result with the real ESR value).
I suggest looking for prices at ebay...   ::)   

rgds, Gyula

Edit: I found this offer, perhaps a good one at present, still not enough in numbers of the caps though: http://www.ebay.com/itm/20x-Maxwell-2600F-2-5V-Supercap-2600-Farad-Super-Ultra-Capacitor-BCAP0010-USA-/150699241350?pt=LH_DefaultDomain_0&hash=item23165fef86

Hi Gyula,


I very much appreciate your response. I also appreciate the time you spent on your calculations. The exponential discharge curve does mess things up a little. As you can see, the capacitor bank will cost $$thousands$$ of dollars. That's something I am not able to swing. But perhaps I will be able to provide convincing evidence using a shorter test duration. My goal is to run a system cyclically ... discharge and generate heat, then disconnect for a recharge and then repeat the cycle. I hope to eliminate the "Battery Effect" as mentioned in other threads by researchers such as M.D.


An important note: Some of Tesla's systems were isolated systems, or closed systems, and did not necessarily run in real-time concert with the grid. When attempts were made to do so, the systems became  ineffective ... no benefit.  I can't cite the patent, but I recall a street lighting system like this ... no true ground or neutral ... just 'floated'.


Thanks very much for your input Gyula,


Regards,


Greg

Hi Gyula,


Thanks again. It would take 12 of those to meet the voltage requirement alone ... about $7200.00. I hope those 'so-called' "experts" out there actually realize what it takes to "simply run it on a capacitor bank" to circumvent the "Battery Effect". It's NOT as easy as "simply running it on a capacitor bank" ... unless you're rich$$$$$$!


Now, I may be reading the EBay offer wrong ... if that's 20 Macwell 2600F 2.5V Supercaps then that's a good deal. I might be able to swing something like that, but I'd still need the bank to be pretty wide. I'll look into it.


Thanks again Gyula,


Greg


P.S. Did you ever watch the movie "The last Star Fighter"? Centauri (actor Preston Foster) mentioned someone by the name of "Gyula" ... cool name!
