Earth Electrical Energy Datalogging Experiments

Jeanna:

I know you have seen this before but here it is again in case it helps other folks:

http://www.ngdc.noaa.gov/geomagmodels/IGRFWMM.jsp

This will compute the dip angle and deviation for your area.  Very easy to use.


@Smokey:

The best materials I have found is carbon (north) and magnesium (south).  But your report of the college experiments reflects what we have learned on our earth battery topics research.  When folks used to say that this was only galvanic action between two dissimilar metals, I would reply that I originally used two copper pipes cut from the same pipe and got both voltage and mA's when aligned properly so, to me anyway, this ruled that out.  There is much to be learned here and you can get amps...many of them.  I did not know this when I started the Kapandze topic but, evidently, there are several others that have replicated his work.  And, hopefully soon, some from Overunity.com will do so.  I would try but, I am honest in sayng the electrical stuff employed is over my head at the moment.  I have learned a lot and hopefully will learn more and then, we shall see.

Please feel free to jump in here and make a small EB and if you have access to a scope, post your findings.  As far as the joule thief goes, I can help you with the basic design but Jeanna is the one to go to for the advanced stuff being experimented on over there. (she is way ahead of me)  The basic ones are simple and easy to do.  I have converted 2 flashlights using these circuits and I can light more leds with less batteries than the original design can.

@SmOky,

This is very good information you have posted below.
It is something we could file away in somewhere labled Tools to use with a earth battery.

@Jeanna

if you dont know the dip angle in your area you can make a make-shift  "compass" with a needle and string.

first place the needle so it rotates horizontally to find the 'magnetic north' from where you are.

then turn it so it rotates vertically to find the 'dip angle'

it should be fairly consistent with depth up to about 40ft deep or so. ( most people dont go down quite that far.....)

occasionally i have come across areas with a magnetic anomoly, where the dip angle varies greatly within a short distance, this is usually near 'hot spots' where the magma is closer to the surface.
such as throughought california or in the desert.

but for the most part, if you use the 'compass' in the spot where you are making your battery you should be good to go.


@ Jim

when i first was taught about the EB in college, we used 2 pieces of copper.  it was not until 10 yrs later when someone showed me that 2 different metals can increase the voltage. i believe this is due to an ectrochemical reaction between the metals when there is a voltage potential already present.  This seems to be in line with the electrochemical series of metals, though i have not tested every existing metal and possible soil compositions.

voltage also increases with size and depth.

current on the other hand, i have not had much success with at all. if i space them far enough apart (or in seperate cans) they can be run in parallel, but with very tiny incremental results (not the current doubling one would expect). in series the voltage will double as expected.

in college we had a 20v setup with about 3 dozen dirtfilled cans on a tabletop.  (again using copper on both electrodes)
there was very little curent though.

i'll have to take a good look at this "joule thief" thing.  i scanned the threads briefly a while back but was confused by the issue, and decided to leave that one alone.. I  have no clue how they are even constructed...
  If something like that can drive the current of an EB to usable levels, then i have a list of 3,000 other places such a device could be utilized.... i.e. anywhere there is a voltage potential...

BTW, magnesium and copper works a lot better than copper and steel. ( at least until it oxidizes and has to be replaced)

Ha ha, the Joule thief topic is fairly full, with a lot of information, lol, If you need assestance finding exact info, try asking Jeanna, she is the best of remembering where it "might" be.

@all,

I'm having a little trouble here in the screen to make posts, where you write the words into, I have noticed this back at the house first, then here at another location in another town, on another computer.

When I get to the bottom of the screen, the words will not scroll up so you can see the line you are typing on, rather it bounces around a bit, I had difficulty in my above post, the last bottom lines I did not being able to see them.

Has anyone else noticed this hapenning, I thought it was my PC back home playing up, but it is hapenning here in a completly different location, on a completly different PC, one has Dialup, the other has Broadband.

Problem is the same,m so its either in Aussie, or does everyone have it.

I also have probs getting a linkup to OU, I see Stefan has done a maintenance thing tooo.

Jim:

No problems here like you describe.  Stefan did do a back-up earlier today, I guess about 6 hours ago and I could not get on but, as of now, no problems on my end here.

Keep up your great work my friend.

I am not having the same problem that you are describing, but for several days now, I have had to push a button 2 times.
The first time I get to a screen that tells me the connection was not made, along with an invitation to try again.
I do and it does; but since you are asking, I am now also wondering if it is not the site.
This thing I just described only happens here on ou.
It never happens anywhere else I go, just here.

nite,

jeanna
