Harvesting Energy from Earths Electrostatic Potential
« on: June 20, 2010, 03:27:26 PM »
Imagine 2 huge conductive disc´s mounted lets say 1m appart isolated above ground, in between a 1F Capacitor.
After some time, the capacitor will be charged up according electric potential level near groud - about 200V/m - to 200V.
If charged, the charge of the capacitor will be about 200Coulomb, thats an energy of 20kJ.
By connecting a load I can harvest that energy - disconnect and recharge - ad infinitum.

The question is what diameter of discs would I need for what charging speed.


Any comments ?
lets try out.

well - will try that out somewhere in "free" space.
In my backyard there is only a bunch of mV using 1m2 disc 1m appart from ground.
That has a capacity of pF - so connecting a voltmeter is difficult.
If I add a capacitor - the wire of the cap distorts my field....
..Have to find my electrostatic meter in the lab ...

It will not. In order a capacitor to charge, charges must move away from an electrode and go to the other.
An electric field in space can't charge an isolated capacitor because there is no path for the electrons to flow.

If I have some caps in series - and charge them - the charge might distribute evenly on the caps - if they have identical parameters.
If I build a plate capacitor - with extra discs inside - this is an identical setup to caps in series.
Whats the difference between floating, isolated discs in an electric field in space and the inner caps of a series cap row ?
So if I have a huge disc cap in space - there is one parasitic cap between lower disc and ground - and another between upper plate and ionosphere.
Well - maybe a single disc which forms a capacitor to ground performs better.

I think the 1F capacitor is connected to the discs - respectively one disc for each pole on the capacitor. The electric current will flow from each disc and charge the capacitor.

A current can flow only in a closed circuit.
No closed circuit, no current, no capacitor charging.

instead of a closed circuit - we have charged particles.

"No closed circuit, no current, no capacitor charging" ; no lightnings ;-)))

Lightnings happen through ionized channels therefore the circuit is looped, like a capacitor that you discharge through a spark gap.

Your "idea" implies spontaneous creation of charges on capacitor plates. But charges don't appear from nowhere. They can't be created. They can only be separated, positives from negatives, and work has to be done against the coulombian attraction.

Fritz:

What you describe is just about what I do with my EER. (Earth Energy Receiver)  With two electrodes in the ground about 15 feet apart, I charge up my 650 Farad boost-cap and, when hooked to a JT circuit, it can run all sorts of stuff, floro tubes, 400 leds, Bedini motor, etc.

My cap is rated a only 2.7 volts and it charges fully pretty fast.  On my scope, I see huge spikes all over the place and I believe this is where the main charge is coming from.  It appears to be pulsed dc right out of the ground and the big cap stores it as useful energy.

Maybe this will help.  I have a series of videos on Youtube with my experimental efforts.

@ Pirate88179

You probably posted it somewhere and I watched your video http://www.youtube.com/user/Pirate88179#p/u/5/qjBAU4HAMfs (Amazing Earth Battery Scope Shots), but it is hard to find, so I ask my questions here:


1) Do you use diodes (e.g. a full bridge) when charging your super cap with the EER (Earth Energy Receiver)?

2) The two electrodes in the ground (about 15 feet apart), what materials are they made from?

3) Different material for each electrode, or the same material for both?


I want to see what sort of spikes I get here in Europe (Austria, near Vienna).

Greetings, Conrad

Conrad:

No bridge, no diodes at all.

Electrodes are:

North (meridian, not magnetic) Carbon rod
South("       ") magnesium block

I discovered by accident that I did not need any diodes.  The system puts out about 2 volts as read on a DMM but, it is pulsed dc so the DMM probably does not read it correctly, plus the spikes are so big they must keep the energy flowing into the cap and not back out of it. 

Since the beginning, I wondered why the energy did not flow from the cap back into the ground, but it does not.

A lot of this was being discussed over at the earth battery data logging topic started by Electricme (Jim) from Australia.

Ah, I hear Austria is a beautiful place, especially Vienna.
