Graphene, the much-hailed wonder material, may be the solution to the world’s water crisis.
One in nine people around the world do not have access to clean, safe water close to their homes and at least 2 billion people are forced to use a drinking water source contaminated with faeces.
Dirty water is a serious public health concern and drinking or washing in dirty water spreads diseases such as diarrhoea, cholera and typhoid. Contaminated drinking water causes over 500,000 deaths each year from diarrhoea, a leading killer of children under five.
First developed by scientists at the University of Manchester in 2004, graphene, an ultra-strong material composed of a single layer of carbon atoms, has been tipped for many uses from hair dye to super long-life batteries.
But one of the material's most exciting properties may be its ability to filter out even the tiniest impurities in water.
Researchers at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) in Sydney have recently found a way to turn ordinary cooking oil into graphene to create what they believe is a much more effective filter than standard methods.
Their breakthrough consists of a thin graphene film that attaches to a conventional filter.....

Neat!
Is there a “world water crisis” or a world water MANAGEMENT crisis?
Neat until some turd world heathens decide it’d be fun to rip them up. You know they will.
A cheaper method would be to not poop where you drink but apparently that’s over some folks’ heads.
Does it filter out salt from salt water?
I went to read the article but got hit with a paywall.
True dat. Municipalities here want to control everyone’s use of water... and they still cannot guarantee its quality...
And they add fluoride for your health :wink
You might not want to research too much then where our drinking water comes from. Remember that fish have to poop too. People forget that.
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.
Like everything else, the scarcity of something is POWER. Controlling water is a big deal.
...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.
Good point.
Right. The Left, the lovers and purveyors of totalitarian power, will use every excuse to obtain it. Totalitarian power is also shown to be the #1 cause of critical shortages in a society.
The Left always has been, is now, and always will be, the CAUSE of misery, oppression, and shortages.
Based on what I read, grapheme potentially can remove salt from water in ONE step, which would be a MUCH less expensive process than distillation (which requires a significant energy input to both heat and cool the H2O).California will outlaw it long before it reaches that point.
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.
Outlaw the idiot environmentalists and there would not be any shortages here in the U.S. Knock off a few dozen dictators and there would not be a food or water shortage on earth.
They’ve been saying this for years. Time to put up or shut up.
