Hallo Reid,
A 12 volt lead/acid battery as found in vehicles makes an excellent voltage source for producing CS. If you want to, you could also connect two in series to get you 24v , which is very close to the 27v used by so many.

A model train or slotcar transformer is also an interesting variation,
giving adequate voltage from the wall power with a lot of safety built in.

Another thought is the output from a bicycle dynamo. Nominal 6v I seem to
remember, which is also OK. If you have enough wind you could perhaps rig up a wind charger. You could also purchase a solar panel, but that would be a bit dismal in the rainy or no sunshine season. The solar panel, windcharger combination might be a working plan.

Those 9v batts should last a very long time. Even the real cheapo's. Maybe
there is a short circuit somewhere, which is draining the power.

Dick,
Also....  in our part of the world, South Asia, the Duracell, Everyready
and other batteries tend to be expensive, crowded out of the market by
cheap, low quality batteries.  Something I've been meaning to ask the
list for a while:  can someone help me figure out how to make a battery
pack?  I'm supposing that constant voltage would be maintained for a
longer period if a number of batteries were ganged up.  Is this a
question of some of the batteries being in series and others in
parallel?  A couple of weeks ago I made a batch of LVDC, that took me
double the normal time.  Even though the cheap batteries were new the
voltage quickly dropped from about 27 down to 16.

Hi, Reid

I have checked the dw in production at 5 hours and had approximately 10
- 12 ppm. (This was at 65 degrees
room temp and dw that tested .5 to begin with.)  Alot depends on
temperature and quality of water.  This
process uses room temperature dw with no heating during the process.  It
is best to check the CS with the
Hanna PWT meter so you know where you are regarding ppm.  The above is
an approximate idea of what you
couod expect.

Dick
