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.
The pioneering solar flight foundation Solar Impulse has launched an ‘Efficient Solution’ label for clean energy start-ups and innovations that can demonstrate their profitability, in a bid to boost investment in the sector.
Milk-based edible food packaging and ready-meal trays made from wood could help reduce the pervasiveness of single-use plastic, a major cause of environmental pollution adversely affecting wildlife, habitats and human health.
Noise is one of the biggest pollutants in modern cities but the risk is often overlooked despite being linked to an increased risk of early death, according to research conducted by scientists.
The big data explosion, which allows scientists to analyse factors such as people’s lifestyles, genes and medical records to develop personalised treatments for conditions, has so far mostly benefitted rare diseases with simple causes. But now, complex problems such as cardiovascular disease and dementia are getting the big data treatment.
