Engineers have figured out how to repurpose disused wind turbine blades to serve as bridges capable of supporting up to 30 tonnes of weight. Turbine blades have a lifespan of around 20 to 25 years, meaning hundreds of wind farms set up at the start of the century are now being upgraded. Decommissioned blades are typically sent to landfill or incinerated, with the thousands of non-biodegradable units now posing a major environmental challenge. In an effort to address the issue, five universities and research institutes in Ireland, Northern Ireland and the US set up the Re-Wind Network, which has come up with several ways the blades can be recycled. Potential solutions include bus shelters, street furniture and telecommunications towers, however bridges already offer a practical way to repurpose the blades, with two footbridges successfully built in Draperstown and Cork. “With so many of these blades due to reach the end of their lifespan, we need to find ways to transform them into something useful,” said Jennifer McKinley, a professor at Queen’s University Belfast’s School of Natural and Built Environment. “I am delighted that by working together we’ve been able to find a way to repurpose wind turbine blades. This can only be a good thing, as without intervention they would end up in landfill or they would have to be incinerated.” A third bridge is set to be built in Atlanta, Georgia, before the research team turn their focus towards increasing the length and size of the bridges. The researchers estimate that there will be around 8.6 million tonnes of scrapped wind turbine blades within the next 20 years, though the glass fibre reinforced polymer material could prove useful for building a huge range of objects, like motorway noise barriers and playground equipment. Three of the engineers from the Re-Wind Network project have also formed a spin-out startup called BladeBridge that will look to commercialise the idea, while also looking for new ways to reuse old turbine blades. “We are partnering with well-known designers here in Ireland to create a portfolio of durable and sustainable products, such as greenway furniture and bridges,” said BladeBridge co-founder Dr Angie Nagle.

ChatGPT has a new upgrade that lets the viral artificial intelligence tool “see, hear, and speak”, according to OpenAI. The update for OpenAI’s artificial intelligence chatbot will allow users to have voice conversations with the AI chatbot and interact with it using images as well, the firm said in a blog post on Monday. “ChatGPT can now see, hear, and speak,” the firm also said in a post on X/Twitter. The features will be rolled out “over the next two weeks” and enable users to “use voice to engage in a back-and-forth conversation” with the AI assistant. With the new features, ChatGPT can be used to “request a bedtime story for your family, or settle a dinner table debate,” according to the company, bringing it closer to the services offered by Amazon’s Alexa or Apple’s Siri AI assistants. Providing an example of how the feature works, OpenAI shared a demo in which a user asks ChatGPT to come up with a story about “the super-duper sunflower hedgehog named Larry”. The chatbot replies to the query with a human-like voice and also responds to questions such as “What was his house like?” and “Who is his best friend?” OpenAI said the voice capability is powered by a new text-to-speech model that generates human-like audio from just text and a few seconds of sample speech, the company said. “We collaborated with professional voice actors to create each of the voices. We also use Whisper, our open-source speech recognition system, to transcribe your spoken words into text,” the company said. The AI firm believes the new voice technology is capable of crafting realistic-sounding synthetic voices from just a few seconds of real speech, and could opens doors to many creative applications. However, the company also cautioned that the new capabilities may also present new risks “such as the potential for malicious actors to impersonate public figures or commit fraud”. Another major update to the AI chatbot allows users to upload an image and ask ChatGPT about it. “Troubleshoot why your grill won’t start, explore the contents of your fridge to plan a meal, or analyze a complex graph for work-related data,” OpenAI explained. This new feature, according to the company, also lets users focus on a specific part of the image using a drawing tool in the ChatGPT mobile app. This kind of multimodal recognition by the chatbot has been forecast for a while, and its new understanding of images is powered by multimodal GPT-3.5 and GPT-4. These models can apply their language reasoning skills to a range of images, including photographs, screenshots and documents. OpenAI said the new features will roll out within the next two weeks in the app for paying subscribers of ChatGPT’s Plus and Enterprise services. “We’re excited to roll out these capabilities to other groups of users, including developers, soon after,” the AI firm said.

The cost of solar power has dropped by nearly 90 per cent over the last decade, according to new research, taking it towards a key level that will make fossil fuel-generated power no longer economically viable. Calculations by Berlin-based Mercator Research Institute on Global Commons and Climate Change (MCC) found that the plummeting price of electricity produced by solar panels – down 87 per cent since 2013 – means the transition to renewable energy sources is “cheaper than expected”. The falling costs of batteries and other renewable technologies could also help supercharge the trend towards cleaner energy and meeting climate targets. “Some calculations even suggest that the world’s entire energy consumption in 2050 could be completely and cost-effectively covered by solar technology and other renewables,” said Felix Creutzig, who led the research. “This is an extremely optimistic scenario – but it illustrates that the future is open. Climate science, which provides policymakers with guidance in its scenario models, must reflect technical progress as closely as possible.” The publication of the research follows recent analysis that showed the cost of batteries fell by nearly 10 per cent last month. Energy analytics firm Benchmark Mineral Intelligence said the drop below $100/ kilowatthour (kWh) in August took batteries past a “tipping point” that puts electric vehicles (EVs) on a price parity with fossil fuel-burning vehicles. As well as accelerating the transition to EVs, the fall in battery prices is also a big boost for renewable energy technologies like solar and wind installations, as they use batteries to store excess energy during periods of overproduction. The falling costs for renewable technologies has been attributed to scientific breakthroughs that make them more efficient, as well as decreasing raw material costs. “Greenhouse gas emissions are higher than ever and the measures taken so far are too weak, but in this politically difficult situation, technological progress provides a ray of hope,” said Jan Minx, head of the MCC Applied Sustainability Science working group and one of the leaders of the latest research. “New scenario models, some of which are starting to be explored, are likely to demonstrate in the foreseeable future that the global climate transition might not be as expensive as previously assumed, and may even be cost saving – provided it is finally tackled.” The research was detailed in a study, titled ‘Technological innovation enables low cost climate change mitigation‘, which was published in the journal Energy Research and Social Science.

A major bank has recorded a 74% surge in the number of reports of vehicle scams in the first half of this year, with victims losing nearly £1,000 on average. The Ford Fiesta is the most commonly-reported model to feature in vehicle-related scams so far this year, according to Lloyds Bank. Bogus offers of BMWs and Audis also feature heavily among the fake ads, with motorbikes and classic cars also cropping up regularly, it added. There is also a thriving trade in fake ads for parts and accessories, such as alloy wheels, the bank said. According to the testimony of scam victims, vans are also often popular because people are seeking cheap models to be converted in campervans, Lloyds said. The findings were based on analysis of scams reported by Lloyds Banking Group customers during between January and June 2023. This was then compared with the same period in 2022 – and a 74% increase was found. Lloyds said victims are losing an average of £998, with people aged between 25 and 34 being the most likely age group to report being duped. Scams work by fraudsters creating fake posts on social media or online marketplaces to advertise vehicles that do not exist. They will include pictures of genuine cars or vans to convince the unsuspecting buyer that they are genuine. When a potential buyer responds, they will often be asked to make a deposit to “secure” the car, or even sometimes to pay the full amount, alongside excuses as to why the car cannot be physically viewed ahead of the payment being made. The fraudster will often apply pressure-selling tactics, telling the buyer the car is very popular, that they have several other offers, or that the payment must be made by a certain deadline, Lloyds said. Victims may be tricked into sending money via bank transfer. As soon as the payment is made, the buyer will be blocked and the seller’s profile will disappear. Occasionally, a fake address will be provided at which to collect the car, leaving buyers with a wasted trip alongside the financial loss. Ford Fiestas have been highly popular in the genuine sales market. Figures released by the Society of Motor Manufacturers and Traders (SMMT) in August indicated that the Ford Fiesta was the UK’s best-selling used car between April and June. The manufacturer recently ended production of the car at its factory in Cologne, Germany. If you do want to buy something you've found through social media, only transfer funds once the car is in your possession Liz Ziegler, Lloyds Bank Liz Ziegler, fraud prevention director at Lloyds Bank said: “Buying directly from approved dealers is the best way to guarantee you’re paying for a genuine vehicle, and always use your debit or credit card for maximum safety. “If you do want to buy something you’ve found through social media, only transfer funds once the car is in your possession.” Here are some tips from Lloyds Bank to avoid vehicle scams: 1. Fraudsters use social media to advertise vehicles that do not exist. Always do your own research and do not part with any money until you have viewed, and tested, the vehicle in person. 2. Check documents. Always ask to see the seller’s logbook, to verify that the seller is the legitimate owner. 3. The safest way to buy a new or used car is often from well-known, approved dealers. Organisations such as the AA offer specific guidance for buying cars unseen. 4. Low prices and pressure selling tactics are often used to target victims. Question if a deal looks “too good to be true” and compare prices from trusted sources. 5. Always use your debit or credit card when you shop online. This helps to protect your money should something go wrong.

Scientists have found that one of the key pillars of theory around how life works – that it depends on carbon – may not be the case on other planets. Here on Earth, life depends on organic compounds which are composed of carbon, and often involve other elements such as sulphur, oxygen, hydrogen, nitrogen and phosphorus. With organic compounds, life is partly sustained by chemical interactions called autocatalysis, which are self-sustaining. That means they produce molecules which then enable the reaction to happen again, and do not need any outside influence to keep going on. In the new study, scientists looked for autocatalysis in non-organic compounds. The theory is that if autocatalysis helps drive a process called abiogenesis – the origin process for life – then this origin process could also come from non-organic matter. Betül Kaçar, an astrobiologist, bacteriologist and evolutionary biologist at the University of Wisconsin-Madison, told news outlet Space.com: “It's important to explore these possibilities so that we have an idea of what all forms of life can look like, not just Earth life.” "One of the major reasons that origin-of-life researchers care about autocatalysis is because reproduction — a key feature of life — is an example of autocatalysis. “Life catalyses the formation of more life. One cell produces two cells, which can become four and so on. “As the number of cells multiply, the number and diversity of possible interactions multiplies accordingly.” The scientists searched in a huge trove of existing scientific documents for examples of autocatalysis, and found 270 different cycles of the reactions. Most of the 270 examples did not feature organic compounds, but rather elements which are rare in life forms such as mercury, or the radioactive metal thorium. “It was thought that these sorts of reactions are very rare,” Kaçar said in a statement. “We are showing that it's actually far from rare. You just need to look in the right place.” Now, it means scientists can test these cycles to get a better understanding of how autocatalysis can work. “The cycles presented here are an array of basic recipes that can be mixed and matched in ways that haven't been tried before on our planet,” said study author Zhen Peng, also an evolutionary biologist at the University of Wisconsin-Madison. “They might lead to the discovery of completely new examples of complex chemistry that work in conditions where carbon- or even silicon-based cycles are too either combusted or frozen out.” The scientists published their findings in the Journal of the American Chemical Society.
