Among Manchester’s proudest scientific developments has to be graphene - it’s very own homegrown wonder material first isolated by scientists at the University of Manchester back in 2004.
A material made from a single atom layer of carbon that is super lightweight, super conductive and super strong, it seems to have endless capabilities in the modern world - from smart clothing to intergalactic exploration.
Twelve years after its discovery via a sticky tape dispenser - and six years since its developers Andre Geim (pictured below) and Konstantin Novoselov were awarded the Nobel Prize for Physics - and interest in graphene has never been so high.
It’s that enthusiasm that a new exhibition at Manchester’s Museum of Science & Industry taps into from July 23, laying out the history of graphite and graphene, immersing audiences in its unique 2D world, and asking them to imagine the endless inventions it can aid....

The oceans are as full as they ever were. THERE IS NO SUCH THING AS A WATER SHORTAGE. There is only a lack of water at the price someone wants to pay.
Sounds promising.
As far a filtering the salt out of ocean water goes, there is a little thing called enthalpy of dissolution that might prove troublesome.
Warlords and statists will disagree with you.
The water is there, but you cant drink it straight from the source. There is an inherent cost to that. The Israelies have gotten the cost down considerably. I think they can make a cubic metre of water drinkable for about $48. Graphene, because it is very cheap, will make it even cheaper. It can bring the cost down into the $30’s.
There’s still the cost of pumping and distribution. But still, if the cost is bearable, imagine the interior of Australia becoming a breadbasket rather than a desert. Or the Sahara blooming.
An Israeli scientist has calculated that the world could support a population of between 45-50 billion people, if resources were utilized correctly.
God filters the salt out of ocean water for free. We refer to it as rain. Sll that needs to be done is capture the rain.
I’ve designed a system that seperates salt from ocean water using the sun via solar evaporation.
Please don’t think so far into the future!
By then all humans will have fried due to Globull Warming, and the surviving cockroaches won’t be able to read the instructions written by bad Chinese interpreters!
If we could free ourselves from environmental propaganda we would be investing heavily into smaller nuclear power generation using thorium (which can dispose of current nuclear wastes). Cheap energy benefits everyone.
If you like graphene thank a white male. Stupid auto correct.
Every part of the world needs potable safe disease free drinking water.
Energy will must be inputted into the system to do the filtering. Enthalpy is like a hooker, they give nothing away for free. Entropy is like a divorce and all is in chaos and greater disorder.
Israel can make 1,000 liters of seawater into drinking water for $0.58. http://www.nextbigfuture.com/2016/07/israel-has-desalination-fresh-water.html?m=1
There are places whee it just doesn’t rain much. On the other hand, the enirowhackos tearing down dams means that an awful lot of desperately needed fresh water is being allowed to flow out into the oceans. If all the rivers were equipped with locks, the fish could still swim upstream along with barge and boat traffic. While the locks were closed, the upstream water could be diverted into canals. If the Mississippi River was diverted 90% of the time, that would be over a billion cubic feet of water per hour. The Sacramento River fifty million cubic feet per hour. Columbia River half a billion. It seems incredibly wasteful to see all that rainfall going out to sea.
The amount of energy is the question. Reverse Osmosis systems require quite a pressure differential and that is generally provided by pumps pressurizing water. The graphene filters supposedly require very little pressure. Possibly so little that just letting ocean pipes 20 feet below sea level fill ground aquifers through a graphene filter would require nothing but gravity, and pumping water back up from the ground is the norm for utilities in places like CA.
