The country wide drought

Hard call to spend $11 on the book for drought hit farmer .Anyway I have some suspicious about title.
Australia Landscape preservation ? I think that in era we talk about processing whole Mars into Earth like planet , Australie deserve also some geo engineering.We don't want to preserve 90 % surface as a dry desert if we could convert into green pasture, bush or lakes.Australia is driest continent on Earth but don't need to be.

Ok there is another solution I've heard to irrigate the interior & its to build a kilometer high moutain range down the west coast inland a bit .
This would create the conditions to give us rainfall in the interior buy changing our climate.
Ireland has less average rainfall than Australia its how we use & store it thats the problem .
But if we did use the desalination plant in Sydney at least it wouldn't be a total waste of money like it is .

The planets flat, let's leave it that way

It's really very simple. There is more than enough water to feed the nation if we all turned to eating mainly fruits and vegetables. Whole food is totally sustainable ,its healthy and economically sound . Hospitals would not be swamped with sick people who have done it to themselves .
And yes I was one of those people but have made the necessary changes and feeling great at 70.
We don't need to be rescuing graziers who are using valuable resources and in many instances exporting their animals to foreign countries by the boatload.
Stop importing food from overseas countries that we can easily grow here in Australia. We have more than enough land but it's being wasted by graziers who understandably are just in it for the money.
What I don't get is the government help out to these drought stricken people giving them money to sustain an unsustainable business.
Simplistic view I know but there is definitely a better way and it's not farming cattle and sheep.

I have always wondered what would happen if we pumped salt water from the coast to somewhere like lake Eyre... Its already salt so no issues with contaminating the ground but would that water then replenish aquifers and/or create a change in climate to induce more natural rain in the area?? More rain, more moisture, more vegetation and then boost the cycle to self sustainability??

Massive cost for sure and no direct payback but would it work??

Fake meat ...plant based & its cheaper to produce ..

Its already here , sources say farming meat animals will be minimal by the end of the century , Air NZ has introduced meatless patties already much to the farming communities dismay ...

16hr 35mins flying farm to sydney dosn't sound right .

Reading through this again, it seems crazy that they can produce 15 million Kgs of tomatoes per year, yet they are in an area that is otherwise useless. Heaps of solar energy though and heaps of salt water to turn into fresh water using that solar energy, so it actually seems like a good idea.

I hope the people in Adelaide like tomatoes as 15 million Kgs sounds incredible. I guess you can always process them down into something else locally if that is an issue, but given that Coles have signed up for the tomatoes must mean that they think they can use that quantity cost effectively.

So, maybe the future is pumping salt water inland a bit and then using a similar setup? Producing freshwater from salt and then selling both? I guess the economics of pumping come into it again, so maybe again it is not financial?

It works for high value crops. Not for growing grain and grazing.

Yeah, I agree. Anything else does not make sense.

This also brings up the argument of whether our traditional farming and grazing could get more efficient easily. If you have rainfall that is light but falls across a large area, I guess that land is capable of of supporting a certain number of cows. The same land probably wouldn't support crops as there may not be enough water for that.

The land support also kangurru and rabbits. So alternative to sparse cattle could be kanguru meat and minced rabbits.

My criticism regards only small technical side of the project, Concentrated Solar.seems to be outdated thinking, no longer economical, Thousand of a drawback if you go into detail: from airplanes, bird killing to many others.If your mirrors are stack by a chance your mirrors are now free to reflect to everything around etc.I saw desert base greenhouse producing veggie from sand, salt water and sun possibly anywhere in Israel.But without solar tower.Maybe SA should ask Israelis experts from the field accustomed with the desert environment, not the Norwegian that most likely use solar melt their ice bergs.But it looks that power tower manic on high decision-making level live in SA as another stupid Aurora solar plant is base on similar nonsense.To be build there 2020.Google initially supported a similar project in US but quickly withdraw when calculations shower that PV solar panel is more cost-effective.

if you read the article, it is a very new installation (2015?) and not a failed attempt at anything else. So, any discussions of other projects are not relevant.

Its funny that for a guy that comes up with all sorts of wacky ideas that you are now criticising an actual build that is actually delivering product on a commercial scale.


Sure, turn up and tell them 'they are doing it wrong' but I think their business seems to be running fine.

Kudos to anyone that can take a novel concept and get it through to a commercial solution.

Will see once tomato shows up in my nearest Coles.At $20 per kg
Concentrated solar! again was good 50 years ago when nobody thought about other means of energy storage.
Now we have Tesla lithium battery in Australia already and a new generation of flow batteries will flood energy market soon.
Besides I look at Port Augusta map and see some hills nearby, So you could pump sea water up the hill and create pumping storage on a massive scale, proven technology.

Nah, if Coles have already signed up to exclusively take their 15 Million Kgs of tomatoes each year, you know they won't be selling them for $20 a kg. Unless of course Coles sells all of its tomatoes for $20 a kg.

Coles or Woolworths don't appear to favour producers when buying goods, so you can bet they think its a good deal.

See, this is where people can over complicate things. Sure photo voltaic is getting cheaper, but in this case you want heat to convert salt water to fresh water. Why convert it to electricity first? even if you could use desalination, is the added complexity worth the minute increase in efficiency?

Again, sometimes what you think are simple ideas may not necessarily be so. In order to pump salt water into a dam for hydro storage, the local producers or farmers or whatever, are not going to be happy about your salt water pushing into the fresh water water-table. So you need to line that dam, which no doubt will increase your costs a lot.

Sometimes its better to put your money where your mouth is. You can come up with all sorts of ideas. Some may be good, some may not be, but to see someone that has actually deployed an idea is far superior to someone saying "I would have done it this way...".

Me personally, I think it would be an awesome idea to have solar powered desalination plants every 10kms, where the heat of the sun evaporates the water, and then condenses it at a higher point, so that you don't need to pump it. You can then use that pressure to pipe it further to the interior. Would it work? NFI. Would it be economical, again, no idea, as without proper costings and feasibility, its just a hare-brained idea.
