Energy from the Ground - Self powered generator by Barbosa and Leal

Hi Clarence,

Here are some suggestions I have in helping you tune up your system.

(1) You say your circuit: "It works with batteries but doesn't work closed loop"
This is not correct because closed loop means: "contains suffient electrical storage
capacity to overide any loop instability". Your batteries provide this but you need
additional storage when the batteries are not present, so what you should
do is provide a supercapacitor always on the circuit between your inverter
and your 12VDC power supply. A 16Vdc supercapacitor would be available
at an automobile audio shop where they install high power 1KW audio amplifiers into
car audio systems. The supercapacitor has much more capacity then the electrolytics
in the powersupply but much less capacity then the batteries have.

(2) I would recommend a 120VAC Variac Variable autotransformer before your 12VDC power
supply so you can adjust the input voltage to the power supply up or down. This will allow
allow you to manually tune the system to optimal voltage levels and give yourself more
running margin.

Variac looks like  this, the red device in this farmhand picture from post #527:

Farmhand's variac is 240VAC you may want a 120Vac Variac for your system.


(3) A second variac could be used as a power spliter where you divide the total systems
power between two different AC pathways. The second pathway might be used to power
a second 12VDC supply to run a grid intertie inverter. Variac transformers because of the
way they are wired do not provide galvanic isolation. But you could purchase a 1:1 120VAC
input 120VAC output turns ratio transformer of adquate Kvar rating to ground isolate the
second pathway so the grid intertie inverter would have it's own seperate ground system
in the intertie (shouldn't influence other parts of the circuit).

Thus, it would really be sweet to see extra power actually going out to the grid from your
ground tuned up system. You would manualy set the second Variac just high enough so that
the supercapacitor voltage isn't discharging.

---

In effect your system would be a rather rare example of a self running system ouputting
all extra power to the grid, sort of independent of where the energy comes from. Once
started by batteries they are switched off and don't contribute to system energy.

Good Luck!

Dear Clarence,
If you think a 120VAC Varic would be benifical to you research I just happen to have an extra unit that I would be willing to donate to a good cause.
These devices are expensive even on eBay.
Send me an email at mmckay@simplexgrinnell.com with a shipping address and I can get it right out to you.

Hello mscoffman,

I know what closed loop IS and what it isnt!
what I said was that the system would not work CLOSED LOOP because the Tripp Lite power supply
which was supposed to be getting FULL voltage to it to make it operate properly was not happening!!!
The lack of FULL voltage was due to the GROUND GRID RETURN not supplying its leg of full voltage as this system is supposed to do.
the rest of the information was meant to convey the the fact that I could operate the TRIPP Lite power supply separate from the system
by means of my mains household voltage and doing this then in conjunction with the -  battery array - inverter - toroids - as an
open ended system to be able to operate everything and test the system to see what was happening and or not happening!
when I get the Ground supply problem solved then I will go back to configuiring it as a closed loop again

I do know what a variac is and I have the same RED type unit and have been using it for years.

I also know Member Farmhand as I was and still am a member of the ENERGETIC FORUM for many years working on Don Smith devices.

I do appreciate your thoughts and considerations and I appreciate also the information on the source for the super capacitors!
I am going to continue with this B&L build exactly as it was stated and shown in the patent info and their demos if it doesnt stay close
to their device then I wont persue it farther.

@ Spokane1 ,
thanks for the offer!

Hello Spokane1,

Again I thank you for your generous offer sir!
I do already have the exact same type variac and have used it for years.

Blessings and Cheers,

Clarence

Clarence,

The devices in the main loop of these systems always seem to be under a kind of stability stress they
don't experience when plugged into utility networks. Utility networks are very fast and very "stiff"
because of the way the are backed. DC to AC inverters are not so stiff. So devices used here need a
little more hold up time. But not necessarily 7Ah worth.

Ultimately the incandescent bulb will need to be removed from the circuit because it is wasting power
that should be made available to the user purposes. The variac can be helpful at doing so initially. Of course
all the variacs will be removed eventually and be replaced by fixed resources.

I was just hoping you don't let inherent circuit instability put you off when you come this far. The circuit
looks very interesting.
