Neat!
Is there a “world water crisis” or a world water MANAGEMENT crisis?
Does it filter out salt from salt water?
I went to read the article but got hit with a paywall.
I know this sounds very cynical, but I suspect the enviros will find something wrong with this material. They have an awful lot invested in their fake water “crisis.”
Graphene is becoming more practical all the time. Not there yet but it’s coming.
...at least 2 billion people are forced to use a drinking water source contaminated with faeces.
::::
Here’s a clue: Don’t defecate in your water supply. Is that really so difficult for people to understand? Sorry, but I have lost compassion for people who have not figured this out on this day and age. Survival of the fittest, I suppose.
Geebus... can't anyone do some basic math? There are only about 6 or 7 billion people. 2 billion would be 1/3 not 1/9th.
They’ve been saying this for years. Time to put up or shut up.
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.
I hate that we still need water. We evolved and left the seas, what? 300 million years ago?
Cut the umbilicus already!
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...
