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.
Concentrated solar power (CSP) could have the potential to energise remote areas of the world, but it faces one major obstacle – the amount of water it uses. Now, thrifty water sprinklers, tailor-made rotors and hybrid sunlight-biomass boilers could cut the water bill of concentrated solar power and even help generate electricity when the sun doesn't shine.
Imagine being able to hear, feel and think – but not see or move. Around you, you can hear doctors and family members saying that you cannot understand or make decisions.
It could help them communicate.
It could help bring affordable electricity to arid regions.
