Sundrop Farm, a $200 million infrastructure located in a South Australian desert, is the first of its kind. The creators had a revolutionary - almost difficult to believe - idea of growing vegetables using sun and seawater. In doing so, they avoid the use of any added chemicals, pesticides, fossil fuels, groundwater, and even soil. The solar powered farm utilizes desalination to remove the salt content from the water - producing fresh water that is then used to irrigate the 180,000 tomato plants inside the greenhouse. It is a marvel of technical advancement.
