“Venice could be saved from sinking into the sea by releasing fat globules similar to olive oil into the water that are ‘programmed’ to form limestone reefs, say architects.
The novel solution for the threatened Italian city, built on silty islands on the Adriatic coast, uses experimental technology that they have dubbed “smart salad dressing”.
It would work by releasing oil droplets into the water that are chemically programmed to react with carbon dioxide in the water, precipitating an artificial limestone carbonate.
Two British architects at University College, London, are among those behind the Future Venice project.
Rachel Armstrong, from UCL’s Bartlett School of Architecture, explained the “protocell” technology.
She said: “This technology is based on the chemistry of oil and water and has the special property of transforming carbon dioxide into a limestone-like substance.”
The globules would form “solid pearls” of artificial limestone that could protect buildings from future damage, she argued. ”
