Offshore wind farms to test business in deep water

Advocates of floating offshore wind platforms say they are cheaper to run and install, less disruptive to sea life, and have greater output than near-shore alternatives.

As wind turbines become increasingly familiar sights along shorelines, developers of offshore floating platforms, which harness the powerful winds further out to sea, are seeking to establish their technologies as a major viable source of clean energy. Bottom-fixed offshore wind turbines – with foundations in the seabed – face depth constraints and can only be … Read more

Hydrogen use doesn’t emit carbon but its production often does. That could soon change

Trucks on Orkney carry hydrogen produced by wind- and tide-powered electrolysis in special lightweight high pressure cylinders, designed to adhere to the low weight limit of the island roads.

Hydrogen can be used to power cars, supply electricity and heat homes, all with zero carbon emissions. The snag is that the vast majority of hydrogen itself is derived from fossil fuels – a fact that scientists are now hoping to change. They plan to clean up production to kickstart a dedicated economy – something that … Read more

Models of dinosaur movement could help us build stronger robots and buildings

Researchers are using computer simulations to estimate how 11 different species of extinct archosaurs such as the batrachotomus might have moved.

From about 245 to 66 million years ago, dinosaurs roamed the Earth. Although well-preserved skeletons give us a good idea of what they looked like, the way their limbs worked remains a bigger mystery. But computer simulations may soon provide a realistic glimpse into how some species moved and inform work in fields such as … Read more

New tests identify contaminated drinking water in minutes, not weeks

Speedy, affordable water tests that can be used in on location and even run continuously will help scientists identify disease-causing bacteria in under an hour and potentially reduce the spread of common illnesses such as diarrhoea, which kills an estimated 842,000 people every year. Hundreds of millions of samples are tested each year to detect harmful bacteria … Read more

Hydrogen-powered boat plots course for the future of ocean travel

Every year, the technologies used to power the Energy Observer in its six-year round-the-world journey are being improved.

The first day that Jérôme Delafosse stepped aboard the Energy Observer, an experimental catamaran run on hydrogen, he knew the plan of sailing around the world on clean energy was a realistic one, he says. Now, the explorer and documentary maker is one year into a six-year odyssey around the globe with his friend Victorien Erussard, an … Read more

Electronic wool to take wearable tech from the catwalk to your wardrobe

Sandwiching doped zine sulphide between graphene in textiles can create glowing clothes.

Engineers are threading circuitry into clothes to create comfortable devices that could make electronic fashion the future of the textiles industry. Smart textiles, where electronics are incorporated into fabrics, have been around for some time, from sensor-laden shirts that keep you cool, to dresses packed with LEDs. Despite these innovations, even the most determined shopper … Read more
