Time for Bradfield's scheme?

[Bobby]

Just think in the US they pump oil 100s of kms from Alaska in about 2m diameter steel pipes.

The Chinese would have the whole Bradfield modified scheme up and going in about 3 years and be growing rice in the great North Food Bowl.

I think internally coated steel pipes can be used for water as this would be vastly cheaper than stainless.

I suspect it is a bit fanciful to think solar panels could supply the pumps as they would require a fair bit of power and would run day and night I imagine.

It is a bit like imagining spare power from windymills could power the gigantic pumps on Mal's Snowy 2 Scheme.

But now ScoMo is on the job anything is possible as he will be there for the next 20 years at least.

When will he start the HYDROGEN FUEL REVOLUTION ?

Stainless steel - do it once - do it properly.
Solar cells are OK - the water would be pumped in the day only.

I honestly don't like the idea of desalinisation. Too many chemicals are required for the process along with even more chemicals to stop fouling and scaling of the membrane.

Eventually they will end up poisoning us. No thanks!

Pretreatment chemicals used for brackish and seawater desalination include pH adjusters, coagulants and flocculants, deposit control agents (antiscalants, dispersants), biocides and reducing chemicals. In post-treatment, chemicals include chlorine, anti-corrosion additives and compounds for remineralization. Cleaning chemicals are also required.

I am thinking fresh water too.
So, that is seasonal from the top end.

Distance from Gulf of Carpentaria to Lake Eyre - 1,677 km

Bobby's daylite robbery!!!

Huge pumps would run in daylite only ? Very doubtful if that would happen. You are talking about a lot of water and not just a trickle.

And the amount of solar panels would be huge to even just turn the big pumps over for a few hours at midday.

You might need an acre of solar panels at each pump site but so what?
Think big - have vision.

yes, that will be a problem.
The more areas we have that flow downhill the better.
can't have a lot of pumping stations. Some will be in isolated areas

[sprintcyclist]

I am thinking of pumps where required to raise the water height.
Then let the water flow down a pipe.

.............For efficient drainage, paved surfaces should have a minimum 1-percent slope. Turf or landscaped areas should have a minimum slope of 2 percent........

http://grounds-mag.com/drainage/surface_water_drainage/

ok. So try using 1 percent slope.

So, supposing we pump the water up to a 10m height and have a 1 degree slope.
The water will run downhill for 570 meters

oooooowwwwwwww, for a 1 degree slope over 1600 kms, we need an overall height of 28 kms.

lake eyre is 15M less that sea level. Not much help there .

HI Brian,

Are you trying to tell us that an invisible harmless gas, that is vital to every living thing on earth, that is in our atmosphere at 0.04%, is going to make our World end?, and is somehow causing a "greenhouse effect" ?



Cuckoo Cuckoo!

The visibility or not, is immaterial, Serial. Most gases are colourless and many are deadly. CO^2 is needed in much smaller quantities than we are presently seeing it accumulate in our atmosphere. It is accumulating at a far higher rate than the earth has seen in it's history. While the amount of CO^2 will not poison us, it will drive the Greenhouse Effect and that in turn drives Climate Change. We will see increased numbers and intensity of storms. We shall see increased numbers and the rate of Drought. We shall see the increased rate of ice melt in the glaciers and ice caps of the Earth, this in turn will increase floods and a rise in sea levels. These are all scientific facts. All we are arguing about essentially is the rate that these will occur. All we are arguing about is the ability of humanity to cope with these effects. Climate Change denialists are scientific nincompoops. They refuse to accept reality.
