Re: saltwater capacitance

Hi Daniel,

An often quoted figure is 0.9nF per bottle for fairly standard 12oz beer bottles.. That number goes from 0.8 to 1.1 nF/bottle depending on many things. So, 12 x 0.9nF gives a value around 10.8nF.

The bottles need to be in salt water too to get a very good connection on the outside.

Cheers,

        Terry

Hi, the bottles are 12 regular Kokanee bottles (regular tinted beer bottle), and the salt is near supersaturation in the water. I will probably be using copper 12 AWG wire. Also, should i put the bottles in a water filled bucket (for second plate), or should i just put them all in a box with aluminum foil on the bottom? Thanks
Daniel

"Hi,

If the construction and bottle type can be described so we all
understand it, I bet one of use with meters and a few similar bottles
or whatever could quickly test it and come up with a pretty educated
number....

Cheers,

         Terry"

        I wonder if any of the standard "beverage" bottles have specs on
average wall thickness?  Or for that matter, do beer bottles in
California have the same dimensions as beer bottles in New York?  If
they came from the same batch and the same brewery sure, but otherwise I
wonder what standards are used?
