Yes, but what about the fish? The enviros want to know!

I wonder how they will tax and control this? I am sure the NY Slimes will have an article soon saying that we are going to run out of saltwater soon. /s
As a rising global population and increasing standard of living drive demand for freshwater......the only reason anyone reports about global thirst is to push the AGW agenda, rather than to actually save lives.
Why is electricity needed to get the activated carbon to absorb the Na+ and Cl- ions? Why can’t the carbon do that of its lonesome? Also how quick does the carbon load up and can it be electrically purged of the same ions into salt water?
Why is it when a lib discovers a freshman year chemistry experiment it is hyped as the discovery of the century?
It seems to me that you could use some highly reflective material developed by people smarter than me to push water from a liquid to a global warming gas and then just pipe it into a drinking well when it condenses.
The salt could be used for McDonald’s fries.
If there is a coast line or a source of gravity and water, you could use that energy to generate the power necessary to run the entire thing.
You might even be able to grow algae while you are at it.
Am I stupid or is this a simple process?
The sentence you quoted was talking about increasing population and standard of living. Neither of those mentions global warming. If large quantities of the oceans were to be converted to fresh water, we’d have deserts blooming, many more plants & food growing, converting CO2. Basically global warming would be a quirky thing of the past, like our ancestors worrying about not getting enough calories to survive winter.
On the same thoughts....how expensive are the electrodes to replace.....eventually they will need to be.

Don’t listen to the man
cause he’s filled the burning sand
with water.
Cool
clear
water.
I loved that as a kid and it was on a blue 45 rpm. too.
Drove my poor mother nuts.
The only problem with all that is there may be some
reason for all that salt water, we go messing with
the balance and who knows what would happen.
Just sayin.
I was thinking the same thing.
Well done!!!
Salt’s already banned in NYC, so it’s a cakewalk from there on in.
I find the carbon nanotube filtration more intriguing. The pores are literally too small for anything larger than water molecules to pass through. So it can remove salt from water, but it can also filter out microorganisms, poisons, metals, etc. Water flows through it 10,000 times more easily than through existing reverse osmosis membranes which require a lot of energy to force water through them.
They’ve been using membranes to convert salt water into fresh water for several decades. All these guys did was make the membrane into a tube. for convenience.
I hope the patent office wasn’t stupid enough to give them a patent on stuff that’s been around for decades.
I think you're giving the discovery too much credit. Middle School seems more likely to me. The article uses the word "could" 19 times. A REAL scientific article would use the word "did". The article also talks of electricity only using the word "volt". The critical word is "power". Voltage is irrelevant, if it takes too much power to run the operation.
Can someone help me with a half-remembered factoid?
It was many years ago and I was speed reading, and it may have been just speculative alternative history trash. But I seem to recall that there was a very low-tech way of desalinizing at sea. It had to do with dragging a small container of water alongside the ship, and the item was either made of a certain material or was designed in a certain way, and the action of passing through the sea in a moving ship was a factor.
Never could find it again but I’m positive I read it somewhere.
