The Seawater Agriculture Revolution

There's plenty of water — we're just running out of the kind we can actually use. This is how one company aims to tackle food insecurity and water scarcity at the same time.

Designed for hot arid countries where the main problem is lack of water

This company has a plan to tackle food security and water scarcity — simultaneously — in the most unforgiving climates. A revolutionary way to grow food in the most unforgiving climates. Seawater Greenhouse has pioneered evaporative cooling that uses non-potable seawater to create efficient coolhouses in regions where fresh water is scarce. Paton has brought this “drought-proof" technique to countries like Australia, Somalia and Tenerife.

“The approach people have now with the way they think about water. Now it's quite different to the way people thought about it a year ago. And we've seen this same thing happen with plastic. If you're somewhere sunny and you're too hot you might put a wet top of your head. And this is exactly the same process. The seawater greenhouse is designed for hot arid countries where the main problem is lack of water. We’re on the precipice of a revolution in the way we use water and consider water. People will say water is a finite resource and we have to use it more wisely. Well, yes maybe, but it's not a finite resource. There is no shortage of water in the planet. Two thirds of the globe is covered in water. It's just a bit too salty and in the wrong place. Converting it into fresh water and evaporating it and using it for cooling in humidifier and all of those good things and extracting minerals from it is not technically very difficult. But it's not what people do,” Charlie Paton - founder, Seawater Greenhouse tells Brut.

Using tomatoes as a reference, Seawater Greenhouses says it could produce up to 750 tons of crops per hectare — reducing costs up to 75% from regular heated greenhouses based on data from Seawater Greenhouse. Paton says even more innovation involving seawater will boost chances of achieving global food security.

    And when there is a problem not having enough seawater?

    That's just stupid. If you desalinate the sea water you have all the fresh water you need.

    This is just a big swamp cooler people been using them for years nothing special here

    Why isn't California doing this?

    we use swamp coolers in the west to do this.. same principal.. just a larger scale.. it only works in arid conditions.. where heat of vaporization can be dispelled efficiently to produce the cooling effect. Of course using salt water is useful .. going to need fertilizers as well.. sand is not fertile normally. maybe animal dung.. or composted shellfish etc.. a source of nitrogen.. diluted to not be too "hot" to burn up the plants.

    That's cool, but the salt buildup is going to be insane. I wonder how that works in the long-term.

    over population is the problem

    How about the socialist country of California?

    You mean like Solar and Wind power??😉

    Stop the population growth and you won't have water, food and land problems. Why have children only to watch them die a horrible death. Stop the madness.

    What would be done with the left over salt? Throw it back into the sea would throw off levels in the ocean.

    How about stop burning our food to make fuel!!

    Misleading. Water is not in short supply everywhere.

    Globally, farmland is becoming more scarce. That's why this tech company has turned to growing food out of thin air.
