Nanofilters could stall looming water crisis 2011-06-02 0:00
Carbon nanotubes may revolutionise the process of converting salt water to fresh water and provide an energy-saving solution to the increasing global demand for fresh drinking water, researchers say.
In a new report, computer modelling was used to study how fluid flows at the molecular level. One of their aims was to find the optimum design for a carbon nanotube (CNT) membrane that can be used in the desalination process.
Thee simulations suggest that this membrane may be 20 to 5,000 times more permeable to water than current commercial scale reverse osmosis membranes, depending on tube density.
“If a new material is found that can maximise water transport through the separating membrane, while at the same time rejecting dissolved ions and other particulates in seawater, reverse osmosis would be a much more efficient process,” said lead author Jason Reese, professor of thermodynamics and fluid mechanics at the University of Strathclyde, Glasgow, Scotland.
Demand for drinking water on the increase
With the global population predicted to reach 9.5 billion by the latter half of this century, the demand for drinking water is only going to increase. Already, more than a billion people are faced with insufficient fresh water resources.
This week, 20 former heads of state, including former U.S. president Bill Clinton and former Japanese prime minister Yasuo Fukuda, warned of an impending "water crisis", and will establish a panel to tackle a worldwide leadership gap on the issue.
Trends in climate change have been shown to predict a redistribution of rainfall globally, with dry regions of the planet only getting dryer.
Huge costs of desalination
Most desalination plants convert salt water to fresh water using reverse osmosis. Pressure is applied to the salt water solution forcing the water through a permeable membrane that separates the pure water from the salts.
There are huge costs associated with desalination plants, however, as they require expensive infrastructure and large amounts of energy. With current technology, it is five times more expensive to desalinate water than to extract groundwater, but CNTs may change this.
Carbon nanotubes are sheets of graphene – one-atom thick carbon – rolled into cylinders. Their versatility lies in the fact that they can be a nanometre in diameter, with a tube length many millions of times longer. They are highly efficient at repelling salt ions. In solution, salts are surrounded by hydrating water molecules, which must be shed in order to pass through the CNTs.
This process takes a lot of energy and as a result doesn’t happen very often. Therefore, the right sized nanotube will optimise water transport while minimising salt ion permeability.
ISIS on the Run: Russian Airstrikes Totally Obliterate Terrorist Forces in Just 72 Hours 2015-10-06 4:38 Russia has just achieved, in 72 hours, what the West failed to do in an entire year.
The Su-34 – World’s best machinery for annihilating terrorists.
Numerous news outlets are now reporting that ISIS forces are in total disarray and even, in some cases, completely on the run following the start of Russian airstrikes last week.

Oregon Gunman Left Hate-Filled Note and Long Struggled with Mental Issues, Sources Say 2015-10-05 23:21
The gunman who carried out the deadly attack on Umpqua Community College was described Friday as a “hate-filled” individual, with anti-religion and white supremacist leanings who has long struggled with mental health issues, law enforcement sources said.
Officials said Friday they had recovered 13 weapons tied to the shooter, Chris Harper Mercer, 26. Six were found at the college, seven were ...

Secretive Trans-Pacific Partnership Trade Deal Has Been Reached 2015-10-05 23:13
After years of negotiations, the Trans-Pacific Partnership trade deal has been reached. The exact details of this deal have been kept secret which leaves little doubt that this deal is bad for White working Americans.
Let’s face it, each one of these so called “free trade” deals in our lifetime has been bad. Remember NAFTA?
