The same process could potentially be used to help the 2 billion-plus people around the world who lack access to safe drinking water. They lack access because of their corrupt governments.
Kenya has one of the world's largest supplies of fresh groundwater. There's water everywhere. Just need to get the corruptocrats and Marxists out of the way.

Wonder how fast it will take the sailing water-maker industry to adopt this?

Their product is also made from soybean oil, making it more sustainable than graphene made from fossil fuels. In the future, the researchers say, it could be made with waste oil. Please. Dont you think youre getting a little ahead of yourself, worrying about the quantity of petroleum that will be used in producing your filters??? I mean, how many supertanker loads of petroleum do you suppose would be required to make all the filters you can sell in the next three decades????

Yeah, sounds absolutely wonderful. Per square foot, how much does it cost and how durable/fragile is it?! Technology is getting better and better. And this is just 2018. The Model T about 100 years ago. What will there be 100 years from now?! Oh yeah, the flying car was in Popular Mechanics in about 1966. Every college physics dept. should have a tech fair just like the typical high school science fair. The college kids would have to design a toy or a widget which could do something. And then each college physics dept would compete in the national arena. With the entire school chipping in, the physics toy competition could be amazing.

Membrane filtration has been around for a long time, including heating the feed with solar energy. The only thing new here is the graphene. The article says nothing about graphene being better in any way than existing technology.
If membrane filtration offered lower energy costs than reverse osmosis, then it would used in large desalination plants. So far it has not; RO rules.

This is such bad news for California because it would actually solve a problem but government always finds a way to create misery from prosperity and happiness.

They talk about a one-square-inch piece of graphene, but it's not clear if they actually have pieces of graphene that big. If and when we get to square-foot-sized pieces of graphene, maybe they'll be used in desal plants.

They’re just now able to manufacture the graphene coated membrane filters large enough for commercial scale operation, that was how I read it.
My question is, how often does it need to be cleaned and how? I can see tremendous application for this, in the marine and RV industries alone. Potable water practically on the spot regardless of facilities, unless you’re in an absolute desert.
To: upchuck
I would love to have that filter to assure the purity of my well water.

Actually they did mention one thing better than other filters, and that is othr filter get clogged with oil and chemcals and reduce flow to the point they stop worki g and either need replacing or cleaning, and graphene filters still alow good water flow regardless of how much oil and chemicals they are blocking.

I’ve read that graphene filters which can be swapped in to existing RO technology plants are incredibly cost effective, and the South Koreans are working on 3D printing of the graphene filters which will make them even cheaper.
This convergence of these technologies will revolutionize water filtration.
