corrosion protection

I wonder if this would work on the early cars. Im always a bit suspect of the things i see on TV

Very little useful testing result information on the site and what is there has the typical qualification phrase: "as much as x amount of improvement". Testimonials are generally worthless; I spent good money on this system therefore it has to be working. Capacitive coupling is likely only to give benefit in the immediate area of the electrodes. Being patented doesn't mean it has to work except in the case of machines that violate the laws of thermodynamics in which case the patent office insists a working model be provided. Jim

OK, so ya put this negative charge on the surface of your car. If ya measure the pH of an acid is is like 3 or less. The definiton of pH is the concnetration of the H3O ion which is positively charged. If you have a negative charge on something, the positively charged things (like an acid ion) would be attracted tot he negative charge. By this reasoning, you are attaracting acid to the surface of your charge not repelling it.

On the cathodic protection stuff, you impose a current on a metal system and your sacrificial metal electrode goes away while you protect your desired metals. If you look in your water heater, you will usually find a passive cathodic protection system.

bottom line... This this has lots of mumbo jumbo and not a lot of good science.
