Dunno

I would also like to know what enviromental impacts this has, converting large amounts of water to fresh - I guess its just a literal drop in ocean..

not too bad actually see ABC (Dr karl) links

Seriously our piddly little army doesnt 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

It is ajoke isn't it
21 million people by the end of July
WOW!
How many has Indonesia, China, India, have??
A nice neutral policy like Switzerland would save us a lot of $
NZ seems to keep their head down OK

Dont mind me Im just rambling on..

me too
What do you think of this? sent it to Dr. Karl but he is too busy

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."
