Food crops grown in underwater biospheres
Posted on Monday, 6 July, 2015

A new way of growing food underwater is being tested out beneath the Bay of Noli in Savona, Italy.
Designed to enable crops to be grown in regions where traditional farming methods are impractical, the appropriately named "Nemo's Garden Project" has been running now for three years.

The plants are grown inside special self-contained biospheres which are anchored to the sea floor approximately 30ft underwater. Despite the unusual location the crops still receive a significant amount of sunlight from the surface and the temperature is maintained at a respectable 25C.

As the sea water evaporates it condenses on the inside of the biospheres which produces a humid environment for the crops to grow. Overall the setup is low cost and remarkably sustainable.

So far the researchers have succeeded in growing several bunches of basil using the technique that have turned out to be almost identical to basil grown using traditional farming methods on land.

A video explaining the project in a little more detail can be viewed below.

OK - If the biosheres are air filled, how does sea water evaporate and condense inside the sphere. If the temperature is a constant 25C ther should be muchdew from the internal moisture. Am I missing something? Other than that, quite interesting.

Are these guys kidding us? Did anybody a part of this study do ANY studying on the sad state of the world’s oceans first? The late great did a great conservation study on the Mediterranean back in the 1970’s that produced some shocking readings. What is the state of this area of ocean today? We’ve got and the size of the state of Maine out there, not to mention islands composed entirely of garbage and plastics free floating as well. So, how about helping gather awareness for cleaning our oceans before rolling ahead to grow our next generation of food in places.

This would be a first step towards that. Get people to see the oceans as something more than the world's dumping ground.
