Bright Idea.

I hardly ever watch TV but sometimes out of the blue something draws me to it.
In this case it was a story on landline and I thought what a cracker of an idea. And as the bloke on the interview said it's not rocket science.
I can't embed ABC video on my site but follow this link, make sure you click on the 'Play Video' Link just above the main story, have a look and I'd love to hear what you think.

From the ABC landline site:-  PIP COURTNEY, PRESENTER: Experts tell us that just 2.5 per cent of all the water on the planet is fresh and very little of that is accessible, locked up in ice caps and deep down beneath the earth. And with so much of the available fresh water used up by agriculture, it's becoming an increasingly scarce resource.

A group of international scientists. which has based itself in outback South Australia, has devised a system of growing crops which doesn't rely one bit on that diminishing fresh water supply.

And as Pru Adams reports, they're now ready to take their ground-breaking technology to the world.
