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.
Applying a coat of paint on the walls of a house may soon help to heat it, saving energy and reducing CO2 emissions. It could also clean the air that we breathe, breaking down chemicals and pollutants, and eliminating harmful pathogens.
In the zero-carbon cities of the future, commuting to work may take the form of hailing a driverless shuttle through an app which ferries you from your door to the nearest public transport terminal. In fact, autonomous shuttles have been in development in restricted areas for the past few years. So what will it take to make them part of our daily commute?
Male seahorses not only become pregnant and give birth, but do so in ways that take different forms, which make them unique research subjects to understand the evolution of pregnancy, according to Dr Olivia Roth from the Helmholtz Centre for Ocean Research Kiel (GEOMAR) in Germany.
Demonstrating safety and changes to city regulations are needed to integrate autonomous shuttles with current systems, say researchers.
Dr Olivia Roth talks about her research on the evolution of male pregnancy.
