Desalination is part of our world today, but has been in use for thousands of years. As water become more scarce, reverse osmosis desalinization has become the accepted technology for creating fresh water from salt water. It is used on ships, yachts and utility companies throughout the world.
The major problem with reverse osmosis is that it is expensive and not very efficient.
Here is a good question, “Is there an alloy that can attract the element sodium when DC Current is applied to it?”
The answer is yes, there is such an alloy. When a screen of this alloy is powered with DC Current, it attracts all of the sodium chloride that passes through it. The result is the collection of sea salt on the screen as the fresh water passes through. This alloy attracts sodium very much like a magnet attracts iron.
A scraper would have to scrape the sea salt off to allow the fresh water to pass through and the salt would have to be collected in several passes before the fresh water was 100% salt-free. If may actually be preferable to keep the fresh water at 98% pure keeping 2% of the sea salt minerals intact.
A device can be made from this desalting alloy that would allow a survivor in a life boat to pour a bucket of salt water through it to obtain instant fresh water.
On this site, I keep looking for different alloys that have significant new properties. Think about it, we went from copper to bronze and brass. All we did was to add tin to the copper for bronze and zinc for brass. Then we moved to iron and added carbon to it to make steel, Today, there are many different steel alloys using chrome, tungsten, vanadium and molybdenum; we get different properties with different alloys. The majik is in the new alloy.
