I have not looked in to Beck's work in probably 15 years if this is the same Robert (Bob) Beck. I have never been a fan of his. Some of the stuff I read back then really made me mad. An article on him was stating that he was calling Rife a quack while Beck was in essence doing a knock off of Rife. Rife's primary frequency was 666hz, while Beck was using .666hz.
And as I pointed out before the 9 volt "colloidal silver generators" do not have enough power to form a true colloid. This is why upon standing a few hours there is a silver mud on the bottom of the container as the non-colloidal particles settle out.
