The drones and cameras that could keep homes secure

The pandemic lockdown was not a good time for burglars, who rely on people being out to make a living. But now, with near-normal life returned, the opportunistic thief may soon find that, having wrenched open the back door, they are greeted by a whirring drone shining a torchlight and filming their faces. Just a few years ago, it was only the wealthy and overly cautious who had security cameras on their property. Today, one in five UK households has a video doorbell to monitor visitors to their home. And with the advent of artificial intelligence (AI) and drones, home security devices are about to rise to new heights. Amazon’s home camera pioneer Ring, based in California, has started consumer trials in the US for its latest product, the ‘Always at Home’ autonomous indoor drone. Expected…

Global power sector emissions may have peaked in 2023, study finds

According to the Ember think tank, emissions from the sector plateaued in the first half of 2023, with just a slight increase of 0.2 per cent compared to the same period last year. During this time, wind and solar were the only electricity sources that significantly increased both their generation, as well as share in the global power mix. Across the globe, 50 countries set new monthly solar generation records in the first half of 2023. China continues to be the leader in solar generation, providing 43 per cent of global growth, while the EU, US and India accounted for about 12 per cent each. But China also approved more than 50GW of new coal power in the first six months of 2023 – despite commitments to reduce its carbon emissions – and now consumes more than 50 per cent of the world’s…

EU opens anti-subsidy probe into Chinese electric car imports

The EC has published a notice of initiation , officially kickstarting its investigation into possibly illegal Chinese electric car subsidies. The document states that the EC has found evidence of loans at favourable rates, tax exemptions and components bought very cheaply. Should it consider this enough evidence of unfair practices, the bloc could impose tariffs on Chinese car manufacturers above the standard 10 per cent EU rate. The probe was first announced last month, in EC president Ursula von der Leyen’s State of the European Union address. In the speech, von der Leyen warned that global markets were being “flooded” with cheaper Chinese electric cars. “The EV sector holds huge potential for Europe’s future competitiveness and green industrial leadership,” she said. “EU car manufacturers…

Budge up: making space for the next generation

Society is far from fairly represented in STEM, portraying a false sense of elitism that deters diverse, budding young talent. The Making Spaces project, led by Professor Louise Archer at University College London, launched in 2020. Funded by Lloyd’s Register Foundation (LRF), the initiative focuses on the growing global phenomenon of ‘makerspaces’ – physical locations designed for people to come together to create and collaborate. The project strives to bridge the inequalities in STEM and to encourage participation from under-represented communities through working in collaboration with practitioners. In 2020, the UK government acknowledged the importance of STEM with £179m of investment in the future of UK science. Funding is vital to fuelling growth and success in STEM but doesn’t directly…

Sunak axes northern leg of HS2, but promises billions for transport links

After weeks of speculation , Sunak confirmed the scrapping of “the rest of the HS2 project” during his closing speech at the Conservative Party conference, held in a former train station in Manchester. Sunak explained his decision to scrap any HS2 connection that is not in the London–Birmingham leg as a result of changing circumstances and rising costs. The move goes against the warnings of former prime ministers, political allies, regional mayors and businesses. “I say to those who backed the project in the first place, the facts have changed,” Sunak said. “And the right thing to do when the facts change is to have the courage to change direction. “So I am ending this long-running saga. I am cancelling the rest of the HS2 project.” HS2 was a central part of Boris Johnson’s levelling…

Regulator forces Hitachi to sell train-signalling arm before Thales merger

The rail arms of both Hitachi and Thales are major global suppliers of signalling systems for mainline and urban tracks. In August 2021, Hitachi announced a €1.7bn deal to acquire the Thales Ground Transportation Business. Last year, the Competition and Markets Authority (CMA) warned that the merger could lead to higher fares for consumers. The body’s independent inquiry group concluded that if the merger was allowed to go ahead, few credible competitors would remain. In response, Hitachi has offered to sell its signalling business in the UK, France and Germany. The CMA said it would still need to approve the purchase, and Hitachi’s key customers in these countries will also need to agree to the transfer of the relevant signalling contracts. But it said that once this requirement is met…

AI designs new robot from scratch in seconds

T he team tested the system by giving it a simple prompt: “Design a robot that can walk across a flat surface.” The computer started with a block about the size of a bar of soap. Knowing it was unable to walk, as instructed, the AI began making iterations of the design. With each new version, the resulting robot improved on previous flaws. After nine tries, the AI algorithm designed a robot riddled with holes and with three legs, rear fins and a flat face. It generated a robot design that could walk half its body length per second – about half the speed of an average human stride. The entire design process – from a shapeless block with zero movement to a full-on walking robot – took just 26 seconds on a laptop. “We discovered a very fast AI-driven design algorithm that bypasses the…

Cheap malaria vaccine receives WHO go-ahead for global roll-out

The R21/Matrix-M vaccine could help reduce the 500,000 malaria-associated deaths that occur each year. The vaccine was developed by researchers from the University of Oxford, the Serum Institute of India and drugmaker Novavax. It is expected to become available by 2024, at a cost of between $2 and $4 per dose. R21 is the second malaria vaccine to receive WHO approval. The first one – known as RTS,S – was developed by GSK and has been sold under the brand Mosquirix since 2022. However, the difficulty in producing doses of RTS,S has made pharmaceutical firms unable to meet the high demand for the vaccine – presenting R21 as an equally effective but cheaper alternative. “As a malaria researcher, I used to dream of the day we would have a safe and effective vaccine against malaria. Now…

Satellite TV company hit with first-ever space debris fine

The Federal Communications Commission (FCC) has issued its first space debris enforcement fine, officials have revealed. The agency has fined DISH $150,000 (£124,000), stating that the company relocated its direct broadcast service EchoStar-7 satellite at the end-of-mission to a disposal orbit “well below the elevation required by the terms of its license”. The move could pose “orbital debris concerns”, according to the regulator. “This marks a first in space debris enforcement by the Commission, which has stepped up its satellite policy efforts, including establishing the Space Bureau and implementing its Space Innovation Agenda,” the FCC said in a statement. The FCC added that DISH admitted liability and will adhere to a compliance plan. However, the satellite TV has issued a statement…

Engineering workforce skill gap threatens UK’s net zero goals

Bill Drury is a former technical director at Control Techniques, a £300m-turnover engineering company. “I can’t remember a time when there hasn’t been a shortage of engineers,” he says. His reaction is one common among engineers when asked about the sector’s notorious skills problem: it’s par for the course. The industry, for all its problem-solving expertise, has never cracked the skills supply/demand conundrum. The IET’s most recent survey on skills found that 47% of respondents reported a technical skills gap in their workforce. This is similar to a 2021 report stating that 49% of engineering businesses were experiencing difficulties in the skill-sets available to them when trying to recruit. This is a problem expected to worsen as the UK works towards its legally binding net zero goal…

Comment: Supporting Gen Z with talent training

Gen Z are the next generation of tech talent. They are increasingly taking up roles in the workforce, with data showing that people under the age of 25 will make up over a quarter (27 per cent) of entry level roles within just a few years. With this new influx of talent comes great potential to transform and disrupt the technology workplace. It is crucial that we give these young workers attention, and invest in their development to champion the skills of the future. But despite being known as “tech-savvy”, the generation who didn’t know life before technology may actually be less equipped for a technical future than we would expect. Traditionally, we see Gen Z attending university to build their skills in technical areas, but university alone won’t meet the market demand for tech skills…

Birmingham to Manchester leg of HS2 expected to be scrapped

Sky News announced the rumour minutes before Chancellor Jeremy Hunt took to the stage at the Conservative Party Conference. Speculation about the future of the project has been circulating for weeks, but both Hunt and Sunak have refused to comment on the future of this section of the high-speed rail link a number of times. HS2 was given the go-ahead in 2020, despite a decade of sharply rising costs and repeated delays to the original project timeframe. The cost of completing the project has ballooned from £33bn a decade ago to an estimated £100bn today. The Independent recently reported that ministers were considering shelving the northern phase amid concerns about increasing costs and severe delays. It said a cost estimate it had seen revealed that the government has already spent £2…

Extreme weather: the technologies used to combat climate change

At the end of last year, the United Nations Foundation reflected that 2022 was a “split screen” in terms of climate change. The world, it said, had taken “several important steps to curb the climate crisis while its impacts continued to worsen”, reminding us of the “increasingly severe and irreversible consequences” of an increase in temperature with floods, record-breaking heatwaves, severe drought in Africa, forest fires and cyclones throughout the year. Cyclones Cyclones are tropical rainstorms with strong, rotating winds, formed when low pressure is created in the oceans near the equator. Thunderstorms move across the surface of the ocean and if the surface water is warm (i.e. 27°C/80°F), the storm sucks up the heat energy from the water and carries it in the converging winds. The…

MoD approves £4bn in contracts to build UK’s next-gen submarines

The submarines will be built under the AUKUS pact – a trilateral security agreement between Australia, the UK and the US, designed to assist Australia in acquiring nuclear-powered submarines. The pact also includes cooperation on artificial intelligence, quantum technologies, undersea capabilities and electronic warfare. The UK’s next-generation nuclear-powered attack submarine programme, known as SSN-AUKUS, will see the construction of the largest and most powerful attack submarines the Royal Navy has ever operated, which will replace the Astute class currently in operation. BAE Systems started early design work in 2021, but the £3.95bn funding will cover development work up to 2028. It will enable the defence firm to move into the detailed design phase of the programme and begin to…

Water firms propose billpayers fund a £96bn plan to improve infrastructure

“This investment is essential to maintain the highest-quality drinking water for a growing population, ensure the security of our water supply in the future and significantly reduce the amount of sewage entering rivers and seas,” said Water UK, which represents the sector. The House of Lords Industry and Regulators Committee recently warned that continued underinvestment would have serious consequences for the environment and the security of water supplies. It also found that Ofwat needed to go further to hold water companies to account for environmental pollution as well as ensure that companies invest sufficiently in infrastructure. Water UK said that under its proposed £96bn investment regime, for the 2025-30 funding period, the number of households receiving support with bills would…

Nasa validates a new AI-enabled form of energy

During the Energy & Mobility Conference & Expo in Cleveland, Ohio, the two organisations presented a lternating direct current (ADC), a hybrid of Thomas Edison and Nikola Tesla technologies. The research has been led by Nasa Langley Research Center scientist Narasimha Prasad PhD, with the goal of developing an AI-enabled technology that upgrades the entire foundation of energy. Currently, the energy sector relies on two different forms of energy: alternating current (AC) and direct current (DC) transmissions. In contrast, ADC has been defined as a hybrid form of energy transmission using AC and DC on the same wires. The new energy transmission option has been identified as safer and much less wasteful than the current two – especially when incorporating renewable energy sources. According…

The new Moon race: behind India and China's space ambitions

The race to the Moon is on – once again. Half a century after humans set foot on the lunar surface for the last time, nations are back at the drawing board, designing missions to reach the Earth’s only satellite. This time, they intend to stay. Towards the end of summer, two nations fought to become the first to land in a spacecraft at the Moon’s south pole. Luna 25 – the first Russian probe to set for the Moon in 47 years – was launched first. However, the spacecraft “ceased to exist” after suffering a technical glitch that sent it crashing into the lunar surface. Two days later, India launched Chandrayaan 3, becoming the first nation to land in the Moon’s south pole, and doing so with a budget of only $74m. Perhaps surprisingly, the US was not among the participants in the race, although…

Dear Evil Engineer: Could I hurl satellites into orbit with a trebuchet?

Dear Evil Engineer, After several years working for a reusable rocket start-up in the US, I feel ready to take a risk and start my own business. I am interested in stylish, sustainable alternatives to rocket launches – something to set my offering apart from all of those the other private space companies jostling for contracts. My big idea is to revive and reimagine an iconic bit of engineering history: the trebuchet. We have access to materials and techniques today that would allow for trebuchets of unprecedented size to be constructed, if there is a business case for it, and I know from my years in the industry that there is demand for cheaper, lower-carbon launches. But is it possible to launch a satellite into orbit with a trebuchet? Yours, Not quite a villain Dear Not quite…

Planning laws relaxed for undersea cable linking Moroccan and UK energy grids

The Xlinks Morocco-UK Power Project is a proposal to create 10.5GW of renewable generation, 20GWh of battery storage and a 3.6GW high-voltage direct current interconnector to carry solar- and wind-generated electricity from Morocco to the UK. As Morocco has far more consistent weather, it should provide consistent solar power to the UK, even in midwinter. The solar panels are expected to produce three times more energy than they would in the UK. Coutinho has confirmed that the proposal has been given the ‘Nationally Significant Infrastructure Project’ status, which means it can bypass normal local planning requirements in a bid to get it built faster. The designation is typically given to upcoming power plants, large renewable energy projects, new airports and major road projects. Xlinks…

Ban on various single-use plastics comes into force this weekend

According to the Department for Environment, Food & Rural Affairs (DEFRA), people living in England use 2.7 billion single-use plastic cutlery items and 721 million single-use plates every year, with only 10 per cent of them being recycled. From Sunday, businesses will be banned from using various items in England, while the supply of single-use plastic plates, trays and bowls has also been restricted. Plastic pollution typically takes hundreds of years to break down, inflicts environmental damage and spreads microplastics, which could be harmful to human health. “This new ban is the next big step in our mission to crack down on harmful plastic waste. It will protect the environment and help to cut litter – stopping plastic pollution from dirtying our streets and threatening our wildlife…

How mechanics found in nature could make quantum computing a reality

The travelling salesperson problem does not sound like a major quandary. The task? Compute the shortest possible route between a list of destinations and return to base. Unfortunately, although it’s conceptually simple to work it out, no one has come up with an algorithm that is efficient enough to run at speed for tasks with more than a short list of destinations. The naive approach of adding up the total distances for all possible routes results in a combinatorial explosion of calculations. Computer scientists have tried all manner of tricks to bring it down from the order of n-factorial needed for the naive approach. But you still wind up with a running time on the order of two to the power of the number of destinations. If you aren’t scheduling an entire lifetime of sales visits, that…
