Osmotic differential across the membrane requires hydraulic pressure be applied to the salty side, in order to persuade the water molecules to travel through the pores. This energy expenditure is more efficient than distillation, but an ongoing needed input for the filtration process to occur.
Drinking water needs a minimum of mineral content for safe long term consumption. The body is not capable of maintaining sufficient mineral balances sans supplementation, when faced with ongoing consumption of mineral free water.

Graphene cannot be cleaned since it is only a few atoms thick. On top of the problem with nano particles, they are cancerous due to ther tiny size.
Let us bring back asbestos and lead amd mercury.

A cheap means of desalinating seawater would be a simply tremendous invention. On a large enough scale it could be used to meet immediate human needs and even to green swathes of the world’s deserts.
That said, I’ve been hearing a lot of cheerleading for Graphene for years. Thus far there hasn’t been much to show that it really is some kind of wonder material.

Comments? I hate that we still need water. We evolved and left the seas, what? 300 million years ago?

Sounds like a plan - currently using Berkey filtration for tap water because the local stuff sucks...maybe they can find cheaper ways to clean the sludge out of water...

They are two separate statistics, thus the “and” conjunction.

Like everything else, the scarcity of something is POWER.Which is why statists like to ruin things - this way they "have to" take it over, you know, for the children or whatever.

Exactly. If you could bet in Vegas on the truth, you’d win a lot of money if you bet the opposite of everything that spews out of the Leftist Lying Machine.
That’s one way to presume what’s true: the OPPOSITE of the Delusional Lying Leftist reports and accounts.

Is there a world water crisis or a world water MANAGEMENT crisis? Neither.
Nutty 'climate change' folks are looking around for a new 'SKY IS FALLING' issue to 'frighten for cash and grants'. Too many people caught on to the global warming hoax.
Now, crazy liberal 'elites' are moving toward 'GLOBAL WATER SHORTAGES' - we're all going to die of thirst's as a substitute.
