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.

A new breed of emergency shelter with built-in solar power, a backpack that gives access to mobile charging and a bag that converts manure into cooking gas are among the new generation of emergency response kits that could help people survive in the wake of a disaster that knocks out their energy supply.
The promise of personalised medicine is not only that it could increase cure rates, but also that it could save people from undergoing treatment when there is no hope of it working, according to Dr Daniela Thorwarth from the University of Tübingen, Germany.
She is working on targeted treatments.
