This is a really interesting idea: giant fresh-water lakes in deserts. We could build the many more desalination plants that would be needed, pump salt water through them to extract the salt, and pipe the fresh water into the sands of deserts, all across Western Australia and South Australia and the Northern Territory, four or five million square kilometres of it - all suddenly productive.

Better still, we could use wind power to power the desalination plants and the pumping stations. And, as somebody wisely suggests, we could stock those giant lakes with fresh-water fish.

People may laugh, but it could work: brilliant ideas are usually mocked at first .......

What are you going to do with all the salt?

The evaporation rate is tremendous out there. I suppose that would mean more rain for someone, somewhere. Hmmm... water vapour in the air, reflects sunlight & would cool the Planet counteracting Global Warming. Hmmm... Might work. ;-)
