Growing vegetables using seawater.

Architects from the Spanish firm Forward Thinking Architecture are planning to design a three-story floating farm on the sea that will use seawater to irrigate the crops.

This farm, covering an area of ​​204,000 square meters, will combine vegetable cultivation on the upper levels with fish farming below, creating a sustainable system capable of producing nearly 10 tons of feed per year.

According to the plan, the top floor of the farm will be covered with solar panels and skylights to generate electricity while allowing sunlight to reach the plants.

The second level is where vegetables and aquatic plants are grown. Waste from the growing area is used to feed fish on the level below, and the fish waste is then used as fertilizer.

The floating farm is equipped with wind turbines as well as wave-powered generators to maximize the use of natural energy. The design also includes a seawater desalination plant, processing and packaging area, so that products can be shipped directly to stores and consumers.

This isn't the first time the idea of ​​a floating farm has been proposed. Last year, a group of independent architects in Spain suggested a taller version of a floating farm. Additionally, engineers in Japan and India are also building floating solar power plants.
