This farm makes tomato plants bloom in the desert using nothing more than sunlight and seawater. Needing no soil, fossil fuels, groundwater, or pesticides, Sundrop Farms grows crops in a hydroponic greenhouse lined with water-drenched cardboard. The 20-hectare farm officially opened on October 6th 2016 near Port Augusta, and their desert-grown tomatoes are already for sale in Australian grocery stores. Conventional farming will not work in the desert region, but that does not matter for this desert farm. It obtains water from the Spencer Gulf, and desalinizes the water using renewable energy. 23,000 mirrors reflect light to a receiver tower to generate solar power. When the sun is shining, the system can provide 39 megawatts of clean energy – that is enough to keep the desalination plant working and power the greenhouse, which is heated during the winter.
