Given the lack of fresh water and its harsh climate, traditional horticulture isn’t feasible in this area. Using technology, they have been growing delicious produce using seawater and sunlight instead.
Their 20-hectare greenhouses require no soil to grow the food and since there is no fresh water, the company has built a 115m high solar tower with 23,000 mirrors pointing to it to power up a desalination plant.
The facility processes over 1,000,000 litres of water per day, turning the Southern Ocean seawater into fresh irrigation water, to produce 17,000 tons of tomatoes, accounting for 15% of Australia’s annual produce.
The hydroponic farm with the desalination plant is ideal for places with no fresh water, inhospitable land or harsh climate. It requires flat land, access to seawater and sunlight to grow tomatoes, cucumbers, peppers and more.
