Climate change ‘wreaking havoc’ on planet’s water cycle, report finds

A report led by The Australian National University has found that global warming is changing the way water moves around the planet, affecting entire ecosystems and billions of people. 2024 was a year of extreme weather. Simultaneous heat waves and catastrophic flooding were a theme of the past 12 months. In November 2024, data from the European Commission’s climate monitor Copernicus Climate Change Service revealed that 2024 was “virtually certain” to be the hottest on record, with warming above 1.5°C. A report – Global Water Monitor 2024 summary report – produced by an international team of researchers from universities in countries including Australia, Saudi Arabia, China and Germany has found that these consistently rising temperatures are wreaking havoc on the water cycle.

National Grid abandons costly and noisy T-pylon redesign, report claims

The National Grid has abandoned plans to roll out new designs for its electricity pylons because of their high cost and noise complaints from nearby residents, The Telegraph has reported. The T-pylon design was first unveiled in 2015 as the future design for Britain’s electricity grid. But since then, the new designs have only been installed in one location in Somerset as part of the new 35-mile Hinkley Point C to Avonmouth connection. Each of the T-pylons built so far support 12 conductors for a total of 460km of new power lines across the whole route. Their design sees six conductor spans attached to each diamond earring-shaped insulator on either side of the structure, with wires installed in sections of up to a dozen T-pylons at a time. But the £17m redesign did not feature as part…

Passive radar can be used for avalanche detection with signals from Starlink, study finds

Researchers at the Fraunhofer Institute for High Frequency Physics and Radar Techniques (Fraunhofer FHR) in Germany have proven that passive radar using signals from satellite mega-constellations is suitable for avalanche detection. The increased snowfall in mountainous areas during winter significantly increases the risk of an avalanche. To protect people and infrastructure, avalanche monitoring is critically important. To prevent an avalanche from occurring, controlled artificial detonations are carried out in the affected area. These trigger the release of huge masses of snow, which thunder down into the valley along a predetermined path. To confirm that the avalanche was triggered as planned, monitoring equipment is employed using methods such as mechanical wires that break when the…

Lidar-equipped robot creates detailed 3D models to assess dangerous areas in disaster zones

A lidar-equipped robot that can create detailed 3D models of its surroundings has been developed by researchers who believe it could be used to assess areas deemed too dangerous for humans. In disaster zones following a chemical plant incident or flooding, emergency services need ways to quickly get an overview of the situation. But in many cases, they are not permitted to enter the scene itself in order to avoid putting themselves at risk. Lidar, which stands for Light Detection and Ranging, is a remote-sensing technology that uses laser pulses to create 3D models of its surroundings. The new robot, developed by a team at German research institution Fraunhofer, uses lidar to produce geometrically accurate 3D environments that are then coloured in using camera images. The end result…

BMW and Yamaha back US firm Phoenix Tailings, which plans to decarbonise rare metals mining

BMW and Yamaha Motor have invested in rare-earth processing start-up Phoenix Tailings, which plans to open a $13m facility in the US by June 2025. In the shift away from fossil fuel reliance comes an increased demand for rare earth and metal elements. These materials have diverse applications in electrical and electronic components, and are increasingly needed for battery technologies including those in electric vehicles. However, production of these strategic metals mostly takes place in Chinese mines. The process of refining them generates a lot of harmful waste that poses significant risks to the environment. US-based Phoenix Tailings claims that each year the mining industry discards over 200 billion tons of waste (known as tailings). Its mission is to be the world’s first clean mining…

Eccentric Engineer: The non-existent N-Rays

How a suspicious physicist debunked the mass hysteria of this acclaimed ‘discovery’ Engineers are very good at designing systems to prove theories. Indeed, any modern physics laboratory could be said to be as much a temple to advanced engineering as it is to theory. But just because you are using all the latest engineering kit to prove your point, it doesn’t necessarily mean that you are looking at the truth. As French physicist Prosper-René Blondlot found out, even the most finely engineered experiment can fall victim to wishful thinking. The discovery of N-rays was announced to the world in 1903 to some considerable fanfare but no particular surprise. In the previous 10 years, invisible ultraviolet radiation, X-rays, radioactivity and electron (cathode) rays had all been discovered, so…

Stratospheric balloons offer space tourism’s alternative to glamping

Stratospheric balloons are cheaper and easier to build than rockets and spaceplanes. They can offer hours of magnificent views of the Earth from within a comfy space capsule. But something has been holding their developers back. This space race has been unfolding largely away from the spotlight. While the attention of global media has been fixated on the likes of Virgin Galactic and Blue Origin and their rocket-powered rides to the edge of space, a handful of companies have been working in the background to offer a more affordable alternative to space tourism, suitable for those with weaker stomachs and in less robust health than required to fly a rocket. Using helium- or hydrogen-filled balloons, these firms want to fly paying passengers to altitudes of over 30km. There, above 99% of the…

Interview: Humanist Chaplain at Massachusetts Institute of Technology, Greg Epstein

Humanist chaplain at Massachusetts Institute of Technology (MIT), Greg Epstein believes that technology – more accurately ‘tech’ – has become the 21st century’s most powerful global religion. He also believes it’s time it had its own Reformation. With a global market worth trillions, devices in the hands of billions, its reach unlimited and the appetite of the growing population of power users inexhaustible, Greg Epstein says: “Tech has become the world’s most powerful religion.” MIT’s humanist chaplain is careful not to use the general term ‘technology’ here: “There are many technologies. But there is only one tech.” The author of Tech Agnostic is talking about a post-digital sub-sect that includes artificial intelligence (AI) and machine learning algorithms, “the technologies that can…

UK must maintain 2030 ban on hybrid cars or become a ‘laughing stock’, experts warn

Labour has been urged to ban the sale of new hybrid cars by 2030 amid concerns that their continued availability will damage the UK’s shift to electric vehicles (EVs). In October 2023, the Conservative government under Rishi Sunak reduced ambitions on a number of green policies, including postponing the ban on sales of new petrol and diesel vehicles until 2035. But Labour reinstated the 2030 ban once it took power in the summer, following commitments made in the manifesto. Nevertheless, in December reports emerged that Labour was considering pushing the ban on hybrids back by five years as consumer adoption of EVs has been slower than anticipated. Now, the head of industry lobby group Electric Vehicles UK (EVUK) has said such a move would be highly damaging for the sector. “The inclusion…

UK’s ambitious sustainable aviation fuel mandate officially comes into force

A mandate on the aviation sector to supplant 2% of its jet fuel demand with sustainable aviation fuel (SAF) has come into force from 1 January 2025. The mandate was first introduced by the previous Conservative administration in 2022 and requires the sector to ramp up its usage of SAF until at least 10% of UK aviation fuel is derived from sustainable sources by 2030. In July 2024, then transport minister Louise Haigh said the Labour government would stick to the previous government’s plan after introducing a bill to support SAF production in the King’s Speech. Made from sustainable sources, including materials such as household waste or used cooking oil, SAF is considered a major tool in helping to lower climate change emissions from air travel – widely regarded as one of the most difficult…

AI assistants could enable ‘social manipulation on an industrial scale’, researchers warn

AI assistants could be used to forecast and influence the future decisions of the consumers that use them, with those ‘intentions’ later sold on to third-party companies, researchers have said. A team of AI ethicists from the University of Cambridge say the tech sector is at the beginning of a “lucrative yet troubling new marketplace for digital signals of intent”, which would include actions such as buying tickets to see films or voting for political candidates. In the future, AI agents including chatbot assistants, or even digital tutors and girlfriends, will have access to vast quantities of intimate psychological and behavioural data gleaned from their conversations. It could then use this data, alongside knowledge of online habits, to build levels of trust and understanding that…

IET Comment: Is e-voting in the UK on the horizon?

Steve Schneider, director of the Surrey Centre for Cyber Security, professor of secure systems at the University of Surrey and chair of the IET Working Group on e-voting. General elections in the UK, with their paper ballots, tend to be accompanied by calls for electronic voting. Yet there are good reasons to be cautious. In the early 2000s the Electoral Commission carried out several pilots exploring modernising the electoral system, which included electronic voting. Their final report made a strong statement that “the level of risk placed on the availability and integrity of the electoral process was unacceptable” and raised concerns around security and transparency of e-voting solutions. No further UK pilots have been carried out to date. The IET has been investigating this topic since…

The digital build: Erecting Everton FC’s new stadium

Construction of Everton FC’s new £555m stadium has relied on the novel use of 4D modelling technology, which is credited with helping to keep the project on schedule and within budget. Football stadiums bear witness to spectacle and, often, pure drama. For Everton last season, there was plenty of both. With the club in the process of building a new 52,888-seat stadium on Liverpool’s Bramley-Moore Dock, they had a total of eight points deducted for breaching financial rules. It looked at one stage that this new ground would not be visited by Premier League clubs any time soon until a much-needed end-of-season surge saw the Toffees narrowly retain their top-flight status. Building stadiums can be equally precarious, says Simon Beards, the principal planner for the new £555m venue, which is…

How France rebuilt Notre-Dame: Blending medieval craftsmanship with cutting-edge tech

Notre-Dame Cathedral is set to reopen to the public this December five and half years after it was badly damaged by fire. The iconic building has been restored using a combination of digital technologies and medieval engineering practices. At around 6.20pm on 15 April 2019, a fire broke out inside Notre-Dame Cathedral in Paris. The fire burned until the next morning, destroying the roof, spire and a network of supporting oak beams so vast it was known as la forêt (the forest). The burning remains (including some 30,000 scaffolding poles, in place because restoration work was already being done on the spire) crashed through Notre-Dame’s limestone vaulting into the main cathedral, causing even more damage. Over 850 years after it was built, one of Europe’s most visited landmarks lay in ruins…

France's next-generation nuclear reactor begins operations after years of delays

France’s most powerful nuclear reactor finally came online over the weekend following years of delay and setbacks. While the Flamanville 3 European pressurised reactor (EPR) in Normandy achieved its first nuclear reaction in September, teams from EDF, France’s state-owned power company, have spent the last few months conducting various tests and inspections prior to its connection to the grid. These tests will continue over the following months as the plant slowly increases its power output to full capacity of 1,650MWe. “Starting up a reactor is a long and complex operation,” EDF said. “It requires the full mobilisation of teams and is carried out at each stage with the highest level of safety and industrial reliability.” The Flamanville plant’s first two reactors originally came online…

Edinburgh Airport to capture turbulent low-level wind energy with wind ‘panel’ tech

Edinburgh Airport has partnered with Scottish clean tech company Katrick Technologies to help it generate renewable energy at its airfield. The airport aims to meet 55% of its annual electricity demand through on-site green technologies by 2028. In 2023, it installed a 10MW photovoltaic solar farm on site together with a 1.5MW battery pack with the aim of this technology providing up to 26% of the airport’s annual energy needs. However, a mid-2024 analysis conducted by Edinburgh Airport revealed a significant rise in its average daily energy demand, increasing from 68.49MWh to 83.70MWh, largely driven by the growing use of electric vehicles and fixed electrical ground power for aircraft. The airport then partnered with Katrick Technologies to evaluate the potential of ground-level wind…

Local councils given £1.6bn to repair roads and fix potholes

The government has promised to fix the UK’s roads and fill potholes with an extra £1.6bn investment that will be distributed to local councils. The Department for Transport (DfT) said the money represents an increase of nearly 50% on local road maintenance funding from last year and goes beyond Labour’s manifesto pledge to fix the equivalent of over 7 million extra potholes in 2025 to 2026. Recent data from the AA found that the number of vehicles damaged by potholes reached a five-year high. In November 2023, the Conservatives announced that £8.3bn in redirected HS2 funds would be spent to try and remedy the issue, but while the funding represented an increase, the Asphalt Industry Alliance said that more than £14bn in central government funding would be needed to fix the backlog of repairs…

Government denies HS2 reports suggesting costs could overrun by a further £9bn

The Department for Transport (DfT) has said a report from the HS2 management team suggesting that costs could rise by a further £9bn are not “accurate or reliable”. An HS2 board paper released in June anticipated that the project was now expected to cost between £54bn and £66bn in 2019 prices – a marked increase from estimates the previous November of £49bn to £57bn. But in a written statement to parliament, the DfT said the estimates did not take into account recent changes to the scope of the project, including efforts to bring in private financing for the final London leg that stretches to Euston. “We do not think these figures are accurate or reliable,” the DfT said, while noting that transport secretary Heidi Alexander has asked the board of HS2 Ltd to provide new cost estimates…
