Sundrop Farms in South Australia is using a combination of solar power and seawater to produce food in the middle of a desert and completely independent of nonrenewable resources.
Every day, seawater is pumped 2 km (1.24 miles) from the Spencer Gulf to the 20-hectare farm. The water is then run through a desalination system that produces up to 1 million liters of fresh water every day, which is then used to irrigate 18,000 tomato plants inside a greenhouse.https://www.youtube.com/watch?v=6pAhSU-EvnI
The whole process at Sundrop Farms is less about creating new technology and more about combining existing technologies in a new way, and while the farm’s system has been criticized as unnecessary by some since tomatoes can still be grown in non-desert parts of Australia, that may not be the case 20 or 50 years from now.
