I went fishing in the freezing cold yesterday with my son who picked up some hand warmers.
.... Could the EB have also been a basic pelteir junction using disimilar metals as part of it's operation to increase it's output. People are getting an output in ordinary soil maybe that extra umph to get it up to 1.5 volts could be realized with a bit of soil tweeking. Many things are considered a salt besides table salt
...

What a good idea!
I love those things and would like to have the recipe for hard times... if you know it.
I would be very willing to sacrifice one of them to a NS generator.
I won't be doing it in the rain or cold either.

QuoteIf it proves fruitful then you could have a series of eb's with every other in ordinary soil and string them together to make a useful battery.

, however, so it will have to wait til spring.
Unfortunately the ground is all shorted and you cannot get them in series, but stubblefield might be workable with a little iron/perlite boost.
thanks.

@jim,

I have a idea on how to use a switch arrangement to tune the joule thief, which I discussed with Bill, so I will post that on the JT forum.

That will be great.
I look forward to seeing it.

kevolts,

So far in my experience more mass has not increased milliamps.  I tried using large copper pipes instead of wire and it produced the same amount as my small copper wire.  What does seem to increase milliamps is extending the wire in length in a northern direction.  I will be doing another experiment soon on my south connection to see whether mass or length has the greater effect on increasing power on that side.  So far mass and even surface area has had a lot less effect on power than distance.  I would love to hear what others have found.  I have done nothing to my soil to try and increase the power of the earth battery.  I really do not like the idea of messing with the soil to get more power.  It seems to me that it might make the system more galvanic.

THAT
is really good to hear.
I was wondering about surface area.

So, all you did was extend the wire and the mA got higher.
If you drop the roll of wire into a place near the meter, the nA do not improve.
It is so good to know... It makes me want to try to go out in the cold rain
(... not really)

thank you,

@  lasersaber;  ah so distance is the key. I really hope that is the case even though that would be a disadvantage for me (not a lot of land) but it would make increasing MA cheaper than mass. When it gets warmer in my neck of the woods New York City, I will go to the beach and test if sand can give off a charge as well.

In my limited experience distance has been what has got me up to 40 milliamps.  It seems strange that after spending $50.00 on copper pipe I had no improvement over my $5.00 worth of copper wire.  I did run out of property going north so I can understand what you are saying.  I have a lot of room heading south so I am hoping for major improvements going that direction.  I will keep you posted.
