All the hoopla of people saying it was worthless that came up when I posted the Altoids tin CS generator got me to wondering so I did a lot of digging. I found plenty of scientific data about its efficacy like maybe..
Silver Bandages FDA Approved
MISSISSAUGA, Ontario -- Covalon Technologies Ltd. ("Covalon") (TSX VENTURE:COV) announces that it has received 510(k) approval from the FDA, for CovaClear Ag(TM), Collagen with silver Antimicrobial Gel Sheet Dressing. CovaClear Ag(TM) is the only hydrated collagen dressing with antimicrobial

In this paper, we fabricated silver-coated polyurethane foams and used it as a bacterial filter for contaminated drinking water. Flexible PU foams were soaked in silver colloidal solutions for 10 h, then washed and air-dried at room temperature. The prepared silver colloidal solutions and silver-coated PU materials were characterized by several techniques including TEM, FESEM/EDS, UV-VIS, ICP-AAS, and Raman spectroscopy. The TEM images showed that the size of silver nanoparticles in colloidal solutions varies from 6 to 12nm. The Raman, FE-SEM/EDS and ICP-AAS data illustrated that silver nanoparticles were stable on the PU foam and were not washed away by water. Furthermore, the microbiological tests (tube tests and flow test) were carried out on silver-coated PU materials with the Coliforms, E. coli, and B. subtilis. The obtained results showed that the bacteria was killed completely with antibacterial efficiency of 100% being observed. Our research suggests that silver-coated polyurethane foams can be used as excellent antibacterial water filters and would have several applications in other sectors.
The United Nations Environment Program (2004) has
listed silver-treated ceramic water filters as an appropriate technology for water
purifications in developing countries and regions affected by natural disaster.
So if NASA, The FDA, and The United Nations is involved with CS
and people still deny it's questionable...
Well, hope that works out for them...
