A groundbreaking greenhouse that relies on sunlight and seawater to grow tomatoes officially opens next week, 300 kilometres north of Adelaide. The company Sundrop Farms spent several years developing the idea at a pilot plant on the outskirts of Port Augusta, before building a commercial facility that is 100 times larger.
"This is a very special project," head grower Adrian Simkins said. "It’s not just a first for Port Augusta, this is a first in the world."
The 20-hectare futuristic-looking facility includes a field of more than 23,000 mirrors that capture the sunlight and direct it to a central receiver at the top of a 127-metre "power" tower. At its peak it produces 39 megawatts of thermal energy, which is used for electricity, heating and making water.
All the water used for irrigating the crops is piped from the Spencer Gulf and converted into fresh water using a thermal desalination unit. Mr Simkins has spent more than two decades running tomato greenhouses in Europe and North America and […]
