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.
How does that compare to this: https: //newatlas.com/new-desalination-method-egypt/39941/
My approach uses an electrically powered alloy pipe
to extract the salt from the sea water (make fresh water).
The salt can, perhaps, be used for consumers and for
manufacturing. This is a high volume/flow rate technology
that can be scaled up with larger pipes.
The other approach uses prevaporization with a new membrane;
a great idea. But then, the water must be vaporized and condensed.
How? With the Sun? If they use heat or electricity, it is not
cheap anymore. Worse still, it is not efficient in terms of quantity
or volume of water delivered.
Thank you for clarifying. What would you do with the sodium chloride byproduct?
It is sea salt. It would have to be filtered for plastic and other
unwanted stuff, but could be sold to people for cooking and eating.
You get a 2Fer; potable water and sea salt.
