Plunge into the waters off the coast of Noli in northwestern Italy, and you might just come across some bubble-like pods lying 6-10m beneath the waves.
These biospheres are the brainchild of scuba diver Sergio Gamberini of Ocean Reef Group, who wanted to find a viable new way of producing food. The open-bottomed biospheres, dubbed ‘Nemo’s Garden’, provide a selfcontained environment for plants to grow, and contain crops such as red cabbage, basil, garlic and strawberries.
There’s no need for expensive heating and watering systems, because the ocean offers protection from temperature fluctuations, while the plants are hydrated by seawater that condenses on the internal surfaces, as seen in this image. The biospheres receive plenty of sunlight, and are protected from pests and fungi that can wipe out crops on the land.
In 2016, the biospheres were rigged up with cameras, fans, intercoms and Wi-Fi, and this year the team aims to establish the feasibility of the project.
