Researchers are developing textiles that could be used for large-scale seaweed farms off Europe’s coast.
Seaweed could be more commonly used as a source of chemicals and biofuel if researchers can work out how to grow it and process it efficiently.
Seaweed is normally grown on underwater ropes, but AT~SEA project researchers believe that textiles could be used to cultivate it more efficiently. They are experimenting with textures and surfaces that will produce the highest yields, and hope to grow 20 kilograms of seaweed per square metre, paving the way for large-scale sea farms in the future.
Horizon’s film crew travelled out to one of the project’s test sites off the coast of Galway, Ireland, to find out more from project coordinator Bert Groenendaal and fellow researcher Guy Buyle, from project partner Centexbel.
Treasure troves of raw materials are resting on the ocean floor and their potential abundance is driving the emergence of deep-sea mining, and throwing up concerns about the environmental impact.
For some people the issue of vaccination isn’t about facts, it’s a matter of faith, and this unshakable belief has become an opportunity for health workers to prepare for potential outbreaks.
Rich deposits of raw materials have sparked a modern day gold rush.
Researchers believe addressing ‘anti-vaxxer’ concerns rests in cooperation, not condemnation.
Re-engineering immune cells and modifying yeast to produce drugs are just two potential applications, says Prof. Toni Cathomen.
