Hi all,

I suppose its a little bit off of a seismometer topic; unless...you're a
science experimenter or could
even consider it a back up battery source for your seismometer
amplifier....or just for pure fun
confirmation or basic personal curiosity.

It uses carbon graphite plate/s, un-coated aluminum plates, water, a little
salt, and the key ingredient is...common
liquid bleach (!).  The bleach more or less amplifies the current ~ 10-13x;
its a relatively strong oxidant.   My big
shoebox size cell got up to ~ 1/8 ampere; which is considerably a lot more
than other small web sourced home
brew (1-2 mA ultra low current) batteries I've seen.  It could probably be
more considered as a "reserve"
type battery; unless one can do ~ frequent 2-3 day maintenance.  The web
site above is like a log of experiments
and comments over 4 days.  Its probably not really new so to
speak....but....enjoy....

Take care, Meredith
