Seawater Greenhouses Rock!

I read about this as a concept years ago. Now, it’s going commercial!
“It’s an inspiring project, more important, it could be argued, than anything else going on in the world. Agriculture uses 60-80% of the planet’s scarce fresh water, so food production that uses none at all is nothing short of miraculous.”
Not only that, but…

“So well has Sundrop’s 18-month project worked that investors and supermarket chains have lately been scurrying down to Port Augusta, making it hard to get a room in its few motels, or a table at the curry restaurant in the local pub. Academic agriculturalists, mainstream politicians and green activists are falling over each other to champion Sundrop. And the company’s scientists, entrepreneurs and investors are about to start building an £8m, 20-acre greenhouse – 40 times bigger than the current one – which will produce 2.8m kg of tomatoes and 1.2m kg of peppers a year for supermarkets now clamouring for an exclusive contract.”

And let’s not forget the lack of pesticides!

The Sundrop Farms System™ harnesses the sun’s energy to desalinate seawater to produce freshwater for irrigation, produce electricity to power our greenhouse and provide the energy to heat and cool our greenhouse. Our seawater drenched greenhouse ventilation cleans and sterilises the air, making it possible to grow crops without chemical pesticides.  The Sundrop Farms System™ system relies mainly on renewable inputs to achieve the best possible outcomes for our planet and the best possible produce for our customers.

They know how to convert the salt into one of the nutrients, or sell it on to other agriculturalists. The Israeli’s have also learned to do this in their desert oasis!

Deserts get little or no rainfall, but often there are aquifers deep below the surface that may hold an abundance of water. The problem is getting the salt out of this water so it can be useful for farmers to grow cash crops. The new oasis solves the problem with an ecosystem that produces a variety of freshwater and salt-hardy crops that feed on saline wastewater from the desalination process. It’s in tune with Mother Earth and affordable for some of the poorest farmers subsisting on areas of encroaching desert.

It just gets better. The Israelis then use the salty brine to grow… fish! Ornamental fish!
Nemo, in fact!
