First post. Had to chime in. I've been doing the colloidal silver thing for about 4 years. I'm the type of guy who thinks it's better to know how and why things work, so... The "generator" is nothing but four 9V batteries hooked in series to make 36 V. If you feel more comfortable shelling out the buks, fine, but here is what I found and use.

Go to a hobby/craft/jewelery store to pick a foot or two of 14 guage .999 fine silver wire.

Pick up some 9V battery connectors and alligator clips at some electrical supply store.

Buy four 9 V batteries and tape the batteries together (separate with boxboard).

Bend an "L" into two 6" peices of your wire, and suspend them through two holes drilled into a thin slice of wood so that 3-4 inches are immersed.

Use and elastic to hold the batteries onto the side of your glass, and attach the alligator clips.

Use only distilled water, NEVER add salt of any sort, and it must be in a glass or ceramic cup.

Particle density depends upon time. Usually 10-15 minutes makes a 6" tall glass full.

The bulk of the design came from this article, but it doesn't tell you everything. The first thing you will notice is I use 4 (36V) batteries instead of their 3 (27V). I backed that decision with much reading, and so should you.

Hope this helps.

I'm holding a position in ECU, missed my stink bid by a hair on Fri, but have been weathering the storm. I'll pipe up if I have something to offer, but mostly learning from those wiser. Tnx.
