Seriously our piddly little army doesn't stand a chance if korea, china, japan or America wanted to invade - its just there for looks and so we can be seen to 'support' other countries in wars. I think we would be better off without it - its not lazy, but minding our own business 
Dont mind me I'm just rambling on.. |
There are over 100 de-sal plants in Florida alone.
including the biggest
I would imagine Florida is a little wetter than Oz
We can't find drinking water for 21 Mil people?
I live on the Central Coast of NSW surrounded by power stations that use salt water to cool the plants.
I have often wondered (with 16% water in the dam) why the power stations can't also desalinate water
I talked to a Guy at a recent conference who worked for a big power Station up north.
I ran the "de-sal at power plant" idea by him and he thought it was a good idea.
Power Stations, as you know, need to keep a base load going.
At night, he said, they need to gradually "step down" their massive generators. CO2 wise, this is not very efficient use of the energy produced by burning the coal. A lot of energy is wasted gradually stepping down the massive generators over a period of hours.
Sometimes they need to expend a lot of energy going to get an extra power station on line to cope with peak demand.
He also said that seawater used for cooling is warmed to 50C anyway, so it is not a lot more to get to 101C.
I suppose it is a matter of economics, perhaps of perception, perhaps of conservative thinking; but the Professor's new technology (below) looks good.
What do you think?

Professor Discovers Better Way To Desalinate Water
Science Daily — Chemical engineer Kamalesh Sirkar, PhD, a distinguished professor at New Jersey Institute of Technology (NJIT) and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water. Sirkar, who holds more than 20 patents in the field of membrane separation, said that using his technology, engineers will be able to recover water from brines with the highest salt concentrations. The Bureau of Reclamation in the Department of Interior is funding the project.
Kamalesh K. Sirkar, PhD, is a distinguished professor of chemical engineering and the sponsored chair for membrane separations and the director for the Center for Membrane Technologies at New Jersey Institute of Technology.
"Our process will work especially well with brines holding salt concentrations above 5.5 percent," Sirkar said. Currently, 5.5 percent is the highest percentage of salt in brine that can be treated using reverse osmosis.
"We especially like our new process because we can fuel it with low grade, inexpensive waste heat," Sirkar said. "Cheap heat costs less, but can heat brine efficiently."

I would like to see a desal-plant for the Murry/Darling alone, -situated somewhere in the upper reaches in Qld.
This would restore some environmental flows, improve the environment and rescue most of Ozzs productive land.
No porn, no alcohol for NT aborigines
Check the web or digg for hundreds of posts.
This is the 13th report on Child abuse.
This one is special as it is 3 months before the election?
Prohibition works? where?
[B]
The latest Bonsi. AKA Howard. AKA Jackboot Johnny- his cleverest move yet
Invents new Tampa for next election?
What is the link/deal with pornography?
Have I gone to sleep and woken up in 1950?
Bonsai is buying 10 Billion$ in Boats
Where is the money coming for this?
Where are the trained staff?
The doctors the police who know about aboriginal culture.
You can't get doctors to work in the bush now so how?
(I went to the local hospital casualty on Sunday night. There were about 100 people waiting. The triage nurse told me some had been waiting 6 hours-this is in a Sydney suburb!)
Howard has 40 NT police working for federal police on border control.
It would be good if all kids in Oz could have a free comprehensive medical/dental/optical/psychological check.
If the impetus for this is sexual abuse why won't Father/Minister Abbot check for STDs?
His lame excuse was that this was not covered by medicare! He decides after all!?
What is he going to do with the people he finds need medical attention?
Where are the re-hab facilities?
You can't get psychiatric treatment
in Sydney unless you are VERY well heeled.
What is the $ budget for this exercise?
or
is the whole thing got some other agenda?
Why just the NT when he has the constitutional right to take over ALL states aboriginal affairs. Why are NT kid more at risk?
Does he need a new mine or nuclear dump on aboriginal NT land?
What about the new US, NT airbase?`
Is this where we are going to swap political prisoners from the USA to go to the new 60mil Christmas island facility?
In the crossfire between left and right commentators on this ; did anyone notice he slipped though the Australian ID card in the dying hours of the Winter Parliament session?.
No? Perhaps that was the point + He gets some 'right wing' and 'bleeding heart' brownie points for the election in 3 months time? by being "tough" on aborigines.
Give me a break!
This whole thing will be lucky to last 12 weeks and then go the way of his various other silly pronouncements on History and/or English teaching.
He is the master illusionist- "Watch here while I slip this one in over here".
The press, as usual, follow like the goats they are;
and Bonsai is home free.!
You have to admire his political astuteness. He is so devious and Machiavellian ++So clever!
He could teach Machiavelli a thing or two about dealing with the media and silencing dissent -within and without- his Party
It is a great pity that he is also a humourless, authoritarian, anti-democratic, anti-human rights, power-hungry, amoral, dissembling, evil, socially divisive, gouging,self-centered liar of the First Degree
Otherwise I'd vote for him
