Construction: NaCl + Cu + H2O A large, open glass container nearly filled with rock salt, pieces of copper laid on salt, then container filled with enough water to submerge the copper - and probably charged with natural DC. All help will be greatly appreciated PS - if this thing works, it would emit Chlorine gas while effervescing so don't try this at home, kids!

The electrons have to flow from one plate to another. Plate Rock Salt/water Plate However, seeing as the rock salt will make the water conduct like crazy, this won't be a very good capacitor. Maybe if you use distilled/deionized water it will work. Or even better, oil. 96 Green Mystique Zetec ATX No mods yet (wife's car but I drive it all the time) "If you want something done right, do it yourself or use an SAE mechanic you can buy beer for."

I agree that it's not a very good capacitor for modern uses. Since natural DC is probably what they were working with, it seems that they were deliberately trying to attract the maximum environmental EMF by making this thing highly conductive... rebuild courtesy of Haines Motorsports, Inc.

You could also "spike" the plate charges with the use of a small Emf resulting in more complete charge separation for Na-Cl ions. If you are interested, aerogels provide excellent dielectric properties. Move only if there is a real advantage to be gained...when you move, fall like a thunderbolt. -Sun Tzu, The Art of War '98 SVT E0 Superchip Y-pipe KKM filter custom 2.5 cat back exhaust UDP linux fish
