Farm Uses Seawater and Solar Power to Grow Crops

Sustainability Problem: Combating hunger

Typically technology has focussed on improving what we farm: genetically modified seeds, better adaptability to climate change, etc. This approach hopes to change how we do farming.

About the technology:

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.

That desalination system is powered by solar energy. 23,000 mirrors focus sunlight onto a receiver tower 115 meters (377 feet) tall to produce up to 39 megawatts of energy per day.

There is no need for pesticides since the plants are grown in coconut husks and seawater sterilizes the air. Herbicides are also unnecessary as the employees weed the plants by hand

Stakeholders;

  • Farmers
  • Disributors
  • Suppliers

Deployment:

This is a pilot system for now. Scaling it is a concern.

If successful, this can be a useful model to farm in typically unfarmable regions of the world.
