i don't know if this is relevant or not, but while I was researching this,
there was a youtube video that was flagged.

https://www.youtube.com/watch?v=rDusf5sjb2MThis seemed so entirely ridiculous that I had to try it, and...
low and behold, tap water does seem to possess an electrical charge separation, when you put foil in it.
at first, there is in the 2-3 hundred millivolt range (short current 0.5 microamps+/-)
3 cups in series I was able to achieve 0.4V potential, for a short time.
it seemed the charge was going away, even when I was not taking measurements,.... hmm
perhaps it was balancing out between the cups. so I let it sit for a long time. 3 cups in series, with the ends shorted out with a small wire, as suggested in the video.
when I returned to measure again, the charge difference was almost entirely gone from the terminals.
HOWEVER::
there was approx. 0.5V potential, to ANY of the 3 cups of water, obtainable in the CENTER of the cup!!!
I remembered what Dr Pollack had said about the E-Zone.
and I made an ad-lib center tap configuration that placed all 3 cups in parallel.
(while the outer terminals were still shorted in series)
I was able to obtain 0.5V and up to 50 milliamps short current, which appeared to be sustainable.
the precise location in the cup to place the + terminal was asymmetrical, im assuming because of the construction.
I plan to make a new test-bed with equal area foil plates, and try to center the charge separation within the cup.
also, I had an alternative theory, if this turns out NOT to be EZ water.
these measurements were made using a digital DC meter
which does not pick up any (A/C) high freq. radiation that foil likes to reflect.
this could be simply picking up peak voltages from a certain bandwidth related to the distances between the foil plates.
using water to store the charge.
in either case, this simple design seems to be a viable power source, if you don't mind a bunch of cups of water laying around somewhere....
