As I was looking on the net about 2 months ago I came across plans to build your own CS generator. This one had a twist, the inventor suggested that you put a hose that is connected to an air pump that is used in fish tanks into your water that you want to make into CS. They also said that you could use pure silver coins instead of the wire.
I can't remember where I say this and have only looked on your site, a little. I will keep looking. Does this ring a bell? Do you happen to remember where this is from? If you do could you please let me know? Thank-You Ed Cox
