Israel continues to steal water and soil
from Lebanon [
3 October 2006 ]
Why pay when
you can steal it? If they complain you can always murder them. The UN observers
have confined themselves to observing. It means they are less likely to be
murdered too. The Izzies are keeping al-Ghajar
so that they can steal the water for themselves. The main
stream media have said nothing. The main stream media are Zionist owned and
controlled.

The only viable political stance for [ Australian ] governments

Water pricing is a sensible answer. Paying what it costs makes farmers move to
more effective crops. Growing rice in semi-arid areas does not make sense.
State politicians are the problem in urban areas. They like restrictions and
bullying the users.
Water Trumps Slaughter
[ 4 October 2008 ]
Taking The Salt Out Of Water [ 1 December 2009 ] Ben Sparrow and Joshua Zoshi met at Simon
Fraser University in Vancouver, while completing their MBAs. Their company,
Saltworks Technologies, has set up a test plant beside the sea in Vancouver
and will open for business in November. Existing desalination plants work in one
of two ways. Some distil seawater by heating it up to evaporate part of it.
They then condense the vapour—a process that requires electricity. The other
plants use reverse osmosis. This employs high-pressure pumps to force the
water from brine through a membrane that is impermeable to salt. That, too,
needs electricity. Even the best reverse-osmosis plants require 3.7 kilowatt
hours (kWh) of energy to produce 1,000 litres of drinking water. The process begins by spraying seawater
into a shallow, black-bottomed pond, where it absorbs heat from the
atmosphere. The resulting evaporation increases the concentration of salt in
the water from its natural level of 3.5% to as much as 20%. Low-pressure
pumps are then used to pipe this concentrated seawater, along with three
other streams of untreated seawater, into the desalting unit. As the diagram
explains, what Mr Sparrow and Mr Zoshi create by doing this is a type of
electrical circuit. Instead of electrons carrying the current, though, it is
carried by electrically charged atoms called ions. Salt is made of two ions: positively
charged sodium and negatively charged chloride. These flow in opposite
directions around the circuit. Each of the four streams of water is
connected to two neighbours by what are known as ion bridges. These are
pathways made of polystyrene that has been treated so it will allow the
passage of only one sort of ion—either sodium or chloride. Sodium and
chloride ions pass out of the concentrated solution to the neighbouring weak
ones by diffusion though these bridges (any chemical will diffuse from a
high to a low concentration in this way). The trick is that as they do so,
they make the low-concentration streams of water electrically charged. The
one that is positive, because it has too much sodium, thus draws chloride
ions from the stream that is to be purified. Meanwhile, the negative,
chloride-rich stream draws in sodium ions. The result is that the fourth
stream is stripped of its ions and emerges pure and fresh. It is a simple idea that could be built
equally well on a grand scale or as rooftop units the size of refrigerators.
Of course, a lot of clever engineering is involved to make it work, but the
low pressure of the pumps needed (in contradistinction to those employed in
reverse osmosis) means the brine can be transported through plastic pipes
rather than steel ones. Since brine is corrosive to steel, that is another
advantage of Mr Sparrow’s and Mr Zoshi’s technology. Moreover, the only
electricity needed is the small amount required to pump the streams of water
through the apparatus. All the rest of the energy has come free, via the
air, from the sun.
Cyprus Will Be Independent Of Rain Water In 2011 [ 20 March 2010 ]
Why kill off your enemies when you can stop them breeding in
the first place? Cut off their water. Their crops fail and they starve. That
is the point of the
United Nations' operation called
Agenda 21. The doings of the Santa Cruz Board of Supervisors sound minor
until they are put in context.

A fresh way to take the salt out of seawater
THERE is a lot of water on Earth, but more than 97% of it is salty and over half
of the remainder is frozen at the poles or in glaciers. Meanwhile, around a
fifth of the world’s population suffers from a shortage of drinking water and
that fraction is expected to grow. One answer is desalination—but it is an
expensive answer because it requires a lot of energy. Now, though, a pair of
Canadian engineers have come up with an ingenious way of using the heat of the
sun to drive the process. Such heat, in many places that have a shortage of
fresh water, is one thing that is in abundant supply.
Mr Sparrow and Mr Zoshi, by contrast,
reckon they can produce that much fresh water with less than 1 kWh of
electricity, and no other paid-for source of power is needed. Their process
is fuelled by concentration gradients of salinity between different vessels
of brine. These different salinities are brought about by evaporation.

This presumably makes sense. It is simple
to prove by experiment. It could make a lot of difference in hot countries. What is curious
is
that the men coming through with this one are not chemists, engineers or
scientists. Are they chancers on the make? Pass but it is possible.

CYPRUS hopes to meet all its water needs through
desalination by 2011, when two new plants for the process are completed. The
total demand for water in Cyprus amounts to 90 million cubic metres annually,
which works out at approximately 140 litres [ 30 gallons ] per person per
day. “One of the government’s priorities was freeing the water supply from its
dependence on rainfall,” said Aegli Pantelaki, from the Agriculture Ministry. By
the end of 2011 this aim will have been realized with the four permanent
desalination hoped to be operational by then.

This makes lots of sense. Saudi Arabia has probably had to do something of the
sort already. The Jews will deal with the issue by robbing Palestinians as part
of their programme of Ethnic
Cleansing in Palestine.
