Jam-resistant quantum navigation tech takes flight for the first time

Advanced quantum-based navigation systems that cannot be jammed or spoofed by hostile actors have successfully flown for the first time in commercial flight trials. Planes rely on satellite-based GPS (global positioning systems) for positioning, navigation and timing (PNT). GPS jamming occurs when a frequency transmitting device is used to block or interfere with radio communications that are stronger than the satellite-based GPS signals. Just last month it was reported that since August 2023 thousands of flights to and from Europe had been affected by suspected Russian jamming of GPS systems. While GPS jamming or spoofing GPS signals is relatively rare and does not directly impact an aircraft’s flight path, it has the potential to disrupt critical economic, defence and strategic activities…

How advancements in electric motor technology are bringing IE5 efficiency to more applications

Electric motors account for around 60 percent of the electricity demand in the UK industry. New developments in the evolution of the synchronous reluctance motor are helping to open up new types of application for use with IE5 motors, as ABB’s Richard Gee, UK Sales Manager, explains. The synchronous reluctance motor (SynRM) is one of the most efficient motors on the market. Compared to an equivalent IE2 motor, a SynRM achieves 50 percent lower losses, significantly reducing energy consumption and CO2 emissions. ABB’s latest generation SynRM is capable of achieving up to IE5 efficiency levels, which as recently as a decade ago were widely considered to be purely theoretical. SynRM and drive packages achieve their high efficiency levels through the use of a specially designed cageless rotor…

Tearing down the PlayStation 5 Slim

Sony released a new version of its wildly popular PlayStation 5 console late last year, which promises to shave off a few grams while reducing its TV cabinet footprint. The original was a bulky beast of a console, even compared with Microsoft’s chunky Xbox Series X, and received a fair amount of criticism for looking more like a router than a gaming machine. The PlayStation 5 Slim goes some way to addressing the issue while maintaining the aesthetics of the original. It is about 30% smaller and up to 24% lighter than the 2020 model, and now includes the option of a removable disc drive, which allows the footprint to be reduced even further. When taking the revised console apart, Sam Goldheart at iFixit noted that it is “built to be opened”. The side panels are all removable by the consumer…

Researchers identify effective method of upcycling PET to combat plastic pollution

Researchers in China have published a review that identifies innovative biotic and abiotic recycling and upcycling methods for PET plastic. The invention of plastics, particularly polyethylene terephthalate (PET), in the 20th century marked a significant technological milestone. Being lightweight, flexible and highly durable, this material could be used for a whole host of applications, from single-use plastic bottles and packaging to clothing and carpets. So popular was plastic that since the 1950s its production has ramped up. Scientists estimate that around 450 million tonnes of plastics are produced every year. However, this large-scale production has led to large-scale plastic pollution as its durability means it is resistant to natural degradation. While over 175 countries have…

North Sea oil and gas operators must keep on track with emission cuts, says industry regulator

As the sector transitions to net zero by 2050, UK North Sea oil and gas operators must focus on initiatives to cut emissions from their production activities, says North Sea Transition Authority (NSTA). Yesterday, the authority held its annual performance review of the 20 oil and gas operators in the North Sea. Oil and gas meet around three-quarters of the UK’s energy needs and, even as demand declines as renewables increase, the UK is expected to remain a net importer until 2050. While oil and gas are expected to remain part of the energy mix for decades as the sector transitions, NSTA works at ensuring targets to cut emissions are kept while meeting the UK’s energy security. Stuart Payne, NSTA chief executive, said: “While the argument for continued domestic production is strong,…

New plant lab will help scientists optimise crops for ‘tomorrow’s atmosphere today’

A unique £3m facility at the University of Essex will help scientists optimise plant performance and increase their resilience as our climate changes. The University of Essex has announced a new flagship Smart Technology Experimental Plant Suite (STEPS). This facility will feature a commercial standard vertical farm unit installed by the Innovation Agritech Group, an indoor field that replicates real-world environments and suites in which CO2 concentration and temperature levels can be raised to imitate a warming planet. As our planet warms, conditions will get hotter and drier and the risks of flooding will increase, all of which will negatively impact agricultural yields. Using this facility, scientists will build on the university’s extensive research into plant productivity, photosynthetic…

CHIPS Act to triple US semiconductor production by 2032, report finds

The US will triple its domestic semiconductor manufacturing capacity between 2022 and 2032 following the introduction of the CHIPS and Science Act, according to a report. CHIPS (Creating Helpful Incentives to Produce Semiconductors) was signed into law by President Joe Biden in 2022 and authorises roughly $280bn of new funding to boost domestic research and manufacturing of semiconductors. The aim of the bill was to strengthen the supply chain and help the US compete against China and Taiwan, the largest producers in the sector. According to the Semiconductor Industry Association (SIA), CHIPS will see the US will grow its share of advanced logic semiconductors (below 10nm) manufacturing to 28% of global capacity by 2032, up from 0% in 2022. China, on the other hand, is expected to produce…

As the Thames Barrier reaches 40, officials say it will need adaptations for rising sea levels

As the Thames Barrier reaches its fortieth anniversary, officials have said it will need upgrades in the future to cope with rising sea levels and extreme weather caused by climate change. The structure – which has been operational since 1982 but was officially opened on 8 May 1984 – helps to protect areas of London lying in the floodplain from high tides and storm surges moving up from the North Sea. Discussions into building some form of enhanced flood protection along the Thames were spurred by the North Sea flood of 1953, which killed over 2,500 people across four countries. In its 40-year history, the barrier has closed 221 times for flood defence purposes, but a plan dubbed Thames Estuary 2100 is currently fielding options to extend its lifespan to the end of the century. At the…

Australia will ramp up production and use of gas until ‘2050 and beyond’

A new policy published by the Australian government promises to prolong the production and use of natural gas throughout the transition to net zero emissions by 2050. The Australian government has released the Future Gas Strategy, a long-term framework that maps the country’s plan for gas production and consumption, and how this fossil fuel will support the country’s transition to net zero by 2050. Australia is one of the world’s largest exporters of liquefied natural gas. While it currently accounts for 27% of the country’s existing energy needs, the bulk of it is exported to countries such as China, Japan and South Korea. The strategy outlines Australia’s commitment to supporting global emissions reductions to reach net zero emissions by 2050. But to do this gas production and exploration…

Microsoft signs carbon capture deal using controversial technology

Microsoft has signed a deal with energy firm Stockholm Exergi to help it meet its ambitions to become a net zero carbon company by 2030 by absorbing emissions from biomass power plants. The deal will see some 3.33 million tonnes of permanent carbon removals from bio-energy with carbon capture and storage (BECCS) at a plant in Värtan, Stockholm. But scientists have previously expressed doubt that this method of carbon removal is an efficient way to reduce global emissions. A 2018 letter to the European Parliament signed by nearly 800 scientists said that “cutting down trees for bioenergy releases carbon that would otherwise stay locked up in forests, and diverting wood otherwise used for wood products will cause more cutting elsewhere to replace them”. It called on the body to restrict…

A singular nuclear explosion in space would threaten a ‘significant proportion of satellites’

The explosion of just one nuclear weapon in space could destroy or permanently damage “a significant proportion of satellites” that are in orbit around the Earth, the UK’s ambassador to the UN has said. Dame Barbara Woodward, who was speaking at the UN General Assembly debate on the Outer Space Treaty, said: “The resultant radiation and debris would render many orbits unusable for a very long time. “There would be highly disruptive and possibly life-threatening consequences for those essential applications, maps, weather [and] risk-monitoring, which would affect all states, not least developing nations.” Woodward’s comments follow a vote from the UN Security Council in April that rejected a draft resolution introduced by Japan and the US that aimed to prevent the development and deployment…

UK government’s climate action plan is unlawful, High Court rules

The High Court has ruled that the UK government’s latest climate action plan to reach net zero emissions is unlawful as the plan does not provide enough evidence that there are sufficient policies in place to combat climate change. In March 2023, the Department for Energy Security and Net Zero (DESNZ) approved its carbon budget delivery plan (CBDP). However, soon after the plan was published, environmental campaign groups including Friends of the Earth, ClientEarth and the Good Law Project took legal action on the grounds that the CBDP fails to properly account for how it would meet the UK’s domestic climate targets, as required by the Climate Change Act of 2008. In February 2024, former chair of the Climate Change Committee Lord Deben provided a witness statement in support of Friends…

Uber faces £250m lawsuit from London’s black-cab drivers for ‘unlawful operations’

More than 10,500 London black-cab drivers have launched a £250m lawsuit against ride-hailing app Uber for alleged unlawful operations in the capital from May 2012 until March 2018. When Uber arrived in London in 2012, the San Francisco-based tech company had its sights set on a share of the thousands of taxi rides that crisscross the capital every day. Soon commuters were opting for the convenience of hailing an Uber via an app rather than hanging around a street corner waiting for a black cab to pass. This invasion of Uber into the capital started off a long-simmering battle between the tech company and London’s black-cab drivers. This was largely based, according to Warwick Business School, on Uber’s early “cavalier approach to rules around insurance and driver ID”, which led to Transport…

Partnership to recover used Nissan LEAF lithium batteries to give them a second life

A new partnership between Nissan and Ecobat Solutions UK will investigate how to recover, repair and repurpose used electric vehicle (EV) batteries from UK salvage operators for second-life applications. Ecobat Solutions UK has announced that it has formed a partnership with Nissan to investigate how used EV batteries within Nissan LEAFs, which were first launched in 2011, can still have a useful life as part of the circular energy economy. EV battery recycling is an issue. While traditional lead-acid batteries are widely recycled, the same isn’t true for the lithium-ion versions used in EVs. These batteries not only contain hazardous materials, but also have a tendency to explode if disassembled incorrectly. In an article featured on the BBC, it is estimated that only about 5% of lithium…

Researchers find way to convert methane emissions from landfill into sustainable jet fuel

A chemical process using non-thermal plasma could contribute to a circular economy by converting methane emissions from landfill into sustainable jet fuel, according to new research. As organic waste decomposes in landfills, it releases a great deal of CO2 and methane. Methane is a potent greenhouse gas that traps 86 times more heat in the atmosphere than CO2 over 20 years. Emissions from unmanaged landfills are set to double by 2050 as urban populations grow, which could seriously affect global warming. Indeed, satellite data has revealed that 1,256 methane super-emitter events from landfills occurred between January 2019 and June 2023. However, researchers at the University of Sydney have potentially found a use for all this methane gas in a chemical process that uses non-thermal plasma…
