• View from India: The circular path to net-zero supply chains

    The supply chain by its very nature, leaves behind a trail of wastage. A circular supply chain would mean that the waste could be treated for reuse or remanufactured, providing a source of revenue. It probably makes sense for supply chains to alter their outlook and look at circularity for environmental reasons. However, a circular approach needs to be integrated into the supply chain right from the early stage. This topic was discussed at the recent UK India Webinar on Digital Manufacturing and Connected Supply Chains . “Circularity is essential for India to achieve its net zero target. The remnants of the supply chain can be repurposed and this function as an allied industry to the supply chain. Waste to repurpose systems need to be put in place. This could create new economic opportunities…

  • Broadband cables to be routed through water pipes in new trial

    The trial has the potential to connect up to 8,500 homes and businesses to faster broadband and the technology will also be used to power new 5G masts to connect people in hard-to-reach areas. Civil works, in particular installing new ducts and poles, can make up as much as four-fifths of the costs to industry of building new gigabit-capable broadband networks. The 'Fibre in Water' scheme will demonstrate what could be a greener, quicker and more cost-effective way of connecting fibre-optic cables to homes, businesses and mobile masts, without the disruption caused by digging up roads and land. The network will also be used to set up 5G masts to bring fast and reliable wireless broadband to hard-to-reach communities where wired solutions are too expensive to deliver commercially. The…

  • Solar nanowire-nanotube filter offers easy access to clean drinking water

    Even today, clean water is a privilege for many people across the world. According to the World Health Organization (WHO), at least 1.8 billion people consume water contaminated with faeces, and by 2040 a large portion of the world will endure water stress because of insufficient resources of drinking water. Meanwhile, the United Nations Children’s Fund (Unicef) estimates that around 1,800 children die every day from diarrhoea because of unsafe water supply, which causes diseases such as cholera. It has thus become imperative that efficient and cost-efficient ways to decontaminate water can be developed. With this need in mind, a team of scientists at Ecole Polytechnique Fédérale de Lausanne (EPFL), led by László Forró, has come up with a new water purification filter that combines titanium…

  • Building Europe’s next ‘Channel Tunnel’

    We take it for granted now, but the opening of the Channel Tunnel was the engineering of a miracle. In an instant, the centres of London and Paris grew closer, as travel times between the two fell to under three hours. Since the link first opened in 1994, an estimated 450 million railway passengers have taken advantage of the connection, transforming business and tourism alike. And now 30 years on, ground has broken on a tunnel that arguably lays claim to being Europe’s next Channel Tunnel. The Fehmarn Belt Fixed Link, as the 18km (11 mile) tunnel is known, is a planned road and rail connection that will create a new link between Germany and Denmark beneath the Baltic Sea. By joining the German island of Fehmarn with the Danish island of Lolland, it will cut what is now a 45-minute ferry…

  • Why electrifying your classic car probably doesn’t make environmental sense

    Electrification of classic vehicles, especially cars, is a divisive subject. The position of the Historic and Classic Vehicles Alliance (HCVA), which is dedicated to ensuring the long-term sustainability of a UK industry with an annual turnover of £18.3bn, is that if a vehicle owner wishes to change the propulsion system in their classic car, then that is their choice. However, they should carefully consider the total environmental impact of a conversion that can often make no logical sense; in fact far from it! If one regards the embedded carbon dioxide from the production of a classic car as a ‘sunk’ environmental impact, adding an electric powertrain and energy-storage system is re-embedding new CO 2 that is unlikely to be recovered due to the very limited use classic cars receive. The…

  • Britain’s energy system gets ‘Future System Operator’ to help boost network resilience

    The new body will boost security and resilience of UK energy supplies and support the transition to net zero emissions. The proposal follows a period of consultation with the energy industry, which backed the creation of the new public body. The FSO will be launched once the necessary legislation is passed and timelines have been discussed with key parties. It will look at Great Britain’s energy system as a whole, integrating existing networks with emerging technologies such as hydrogen. The FSO will be a new public body founded on the existing capabilities of the Electricity System Operator (ESO) and, where appropriate, National Grid Gas (NGG). It will work with energy suppliers and networks to balance the UK’s electricity systems and ensure continued energy resilience and security of…

  • Book reviews: Jonglez ‘Secret Guides’ to Glasgow, Paris and Los Angeles

    The ongoing war in Europe has dealt another blow to a global travel industry already crippled by the Covid pandemic. Many would-be travellers, including myself, have had to put their plans on hold again (I have been planning for some time to visit my native Ukraine) and resort instead to vicarious travels using memories, imagination, maps and the internet. As well as guide books, of course. For many years, E&T has been writing about the multi-award-winning ‘Secret’ series of guide books from the international publisher Jonglez, now based in Berlin. For me, their main time-tested feature is that they are equally useful both for real travellers and for the so-called ‘armchair buccaneers’ – whether voluntary or forced. By pointing out the hidden and little- known features of towns, cities and…

  • Russian gas exodus will lower European carbon emissions, analysis suggests

    The research from DNV Energy estimates that 34 per cent of the energy mix in Europe will come from non-fossil fuel sources in 2024, two percentage points more than the pre-war forecast.  Overall, gas use is expected to drop an additional 9 per cent in 2024 compared to the pre-war model. The biggest percentage increase in alternative energy sources will be solar – up by 20 per cent in 2026.  The delayed retirement of some of the continent’s nuclear power plants is also an important component of filling the gap, DNV said. According to the research, although some coal is needed in the short term to meet Europe’s energy demand, by 2024 postponed retirements and higher nuclear utilisation will be important to cover the shortfall of natural gas.  Emission levels from energy are estimated to…

  • Artificial fingertips give robot hands human dexterity

    Typically, robot hands lack dexterity because artificial grippers do not have the fine tactile sense of the human fingertip, which is used to guide our hands as we pick up and handle objects. “Our work helps uncover how the complex internal structure of human skin creates our human sense of touch. This is an exciting development in the field of soft robotics - being able to 3D-print tactile skin could create robots that are more dexterous or significantly improve the performance of prosthetic hands by giving them an in-built sense of touch,” said Professor Lepora, a researcher from the University of Bristol. The sense of touch in the artificial fingertip was created using a 3D-printed mesh of pin-like papillae on the underside of the skin, which mimics similar structures found between the…

  • Treated plastic waste good at absorbing carbon, team finds

    The new chemical technique developed by Rice University researchers offers a potential method to turn waste plastic into an effective carbon dioxide (CO2) sorbent for industry. The Rice lab describes it as a “win-win for pressing environmental problems”. Rice chemist James Tour and Rice alumnus Wala Algozeeb, graduate student Paul Savas and postdoctoral researcher Zhe Yuan reported in the journal ACS Nano that heating plastic waste in the presence of potassium acetate produced particles with nanometre-scale pores that trap carbon dioxide molecules. These particles can remove CO2 from flue gas streams, they reported. “Experts can fit point sources of CO2 emissions like power plant exhaust stacks with this waste-plastic-derived material to remove enormous amounts of CO2 that would normally…

  • Hands-on review: Zhiyun Smooth 5 smartphone gimbal

    We've reviewed a number of Zhiyun gimbals in recent years, but that's not even the half of the Chinese firm's dizzying pace of releases, seemingly slotting a new gimbal into a specific niche every few months. If it's not an entirely new gimbal range, it'll be a refresh of an existing product, often including those with an immediate predecessor still decidedly fresh in many people's minds. Still, technology moves at a pace these days, you snooze you lose etc, so here we are checking out the Smooth 5, one up from the 4. What's new? Moving as it must in tandem with advances in smartphone capability - which in turn raises exciting new use cases for the hardware, which in its way begets heightened creative demands from users of peripherals - Zhiyun is firmly positioning the Smooth 5 as the…

  • MPs want clarity on takeover of Welsh chip fab by Chinese-state backed firm

    In July 2021, it emerged that Nexperia – a Dutch chip firm wholly owned by Shanghai-based Wingtech – had confirmed plans to acquire the UK’s largest chip producer, Newport Wafer Fab in a deal valued at £63m. Prime Minister Boris Johnson had asked the National Security Advisor to take a look at the deal after the government initially decided not to intervene, despite admitting that semiconductors are critical to the UK’s national security and wider global interests. Now, the Foreign Affairs Committee has called on the government to clarify the circumstances in which the National Security Adviser was asked to engage in the review and why Johnson asked for it to be undertaken in the first place. They also question why the review was never taken. The Committee also urged for greater clarity…

  • Fire safety pledges cost housing developers further millions after Grenfell Tower

    Development company Crest Nicholson announced today that it would be signing up to the government’s new 'Building Safety Pledge', which commits developers to new guidelines for work on potentially unsafe cladding on buildings between 36ft (11m) and 59ft (18m) high. The firm became the first builder to commit to signing the pledge to fund retrofit works on buildings over 11m in height. Levelling-up minister Michael Gove had given house builders until today, April 5, to sign the pledge. He had previously warned of dire commercial and financial consequences - including blocking planning permission and even a potential ban on trading - for any company that failed to fix historical fire safety problems, such as dangerous cladding similar to that which caused the devastating fire at Grenfell. …

  • ‘Freeze-thaw battery’ stores electricity long-term for seasonal release

    The small prototype device, developed by scientists at the US Department of Energy’s (DOE) Pacific Northwest National Laboratory, could be especially useful for storing energy from intermittent sources, like solar and wind energy. “Longer-duration energy storage technologies are important for increasing the resilience of the grid when incorporating a large amount of renewable energy,” said Imre Gyuk, director of energy storage at DOE’s Office of Electricity, which funded the work. “This research marks an important step toward a seasonal battery storage solution that overcomes the self-discharge limitations of today’s battery technologies.” Renewable sources ebb and flow with natural cycles, which can make it difficult to include them in a reliable, steady stream of electricity. In the…

  • ISS to welcome first private astronauts

    Axiom, alongside Nasa and other industry players, has hailed the launch as a “turning point” in the latest expansion of commercial space ventures, collectively referred to by insiders as the low-Earth orbit economy: “LEO economy” for short. Weather permitting, Axiom’s four-man team will lift off on Friday (8 April) at the earliest from Nasa’s Kennedy Space Center in Florida. They will rise atop a Falcon 9 rocket furnished and flown by Elon Musk’s commercial space launch venture SpaceX. “It is the beginning of many beginnings for commercialising low-Earth orbit,” Axiom’s co-founder and executive chairman, Kam Ghaffarian, told Reuters in an interview. “We’re like in the early days of the internet, and we haven’t even imagined all the possibilities, all the capabilities, that we’re going to…

  • ‘At a crossroads’ to a liveable future: UN ‘file of shame’ urges rapid climate action

    The UN’s Intergovernmental Panel on Climate Change (IPCC) science body has today released the third part of its sixth assessment report, spelling out how to cut emissions by switching to increasingly cheap renewables and fuels such as hydrogen, as well as energy efficiency, capturing carbon and planting trees. The first "code red" part of the report, released in August 2021, was considered essential in sounding the "death knell" for fossil fuels . The second part, released in February this year and which followed the intense climate deliberations at COP26, was billed as " an atlas of human suffering ". Now the third and final part of the IPCC's report starkly positions humankind as being "at a crossroads". Meeting goals agreed by countries to limit temperature rises to 1.5°C or below 2…

  • First audio recordings of Mars made by Nasa’s Perseverance rover

    The team operating its SuperCam2 instrument (pictured below) believes that the study of the soundscape of Mars could advance scientific understanding of the Red Planet. Perseverance made its first sound recording on Mars on 19 February, the day after its arrival. These sounds fall within the human audible spectrum, between 20Hz and 20kHz. Image credit: nasa Despite the recordings, Mars is thought to be very quiet, with the team mistakenly believing that the microphone was no longer working on several occasions as it failed to pick up any noise. Apart from the wind, natural sound sources are rare. The team has also been focusing on the sounds generated by the rover itself, including the shock waves produced by the impact of the SuperCam laser on rocks and flights…

  • Carbon tax on imported goods needed to stop ‘offshoring’ emissions, MPs say

    MPs on the Commons Environmental Audit Committee (CEAM) called for the tax as a way to stop domestic firms from “offshoring” their emissions. Taxes are currently imposed on carbon emissions from UK-made products. In a report, the MPs said that putting a price on imported carbon can incentivise sectors to move away from carbon-intensive practices and promote behavioural changes towards the creation of more low-carbon products. Currently, the UK’s emissions figures do not include carbon from imports, which understates the true picture of the carbon associated with UK consumption. CEAM acknowledged that the extra charges could be passed onto consumers without greater incentivisation for the development of more low-carbon products to ensure people are not adversely affected by higher prices…

  • Engineers returning to work after career break boosted by new partnership

    Aquila Nuclear Engineering, a Cyclife EDF group subsidiary, will offer a pilot STEM Returners programme at their site near Winchester, Hampshire, starting with the role of senior mechanical design engineer. The role will be open to engineers who have struggled to return to their career through standard recruitment channels. STEM Returners programmes act as a ‘returnship’, allowing candidates to be re-integrated into an inclusive environment upon their return to STEM. Annual research from STEM Returners (published as ' The STEM Returners Index ') has revealed the challenges that engineers face when looking to return to work following a career break. Recruitment bias is shown to be the main barrier to entry. The STEM Returners’ programme aims to eliminate such barriers by giving candidates…

  • View from India: UK and India synergise to foster prosperity

    India ranks 46th in the Global Innovation Index in 2021 by the World Intellectual Property Organisation, and occupies 63rd place in Age of Doing Business as per the World Bank Ease of Doing Business 2020. Several factors have made India conducive for global investments. It’s not just the diverse business landscape or the fact that the country is one of the world’s fastest growing economies. The Government of India (GoI) has chalked out policies for economic growth. A case in point is the Make in India initiative and Production Linked Incentive scheme (PLI) among others. The Ministry of Heavy Industry & Public Enterprises has rolled out an Industry 4.0 initiative titled SAMARTH Udyog Bharat 4.0. The endeavour is a step towards the creation of a sustainable ecosystem for leveraging Industry 4…

Taking everything he learned from three decades in pursuit of sonic excellence, his new company's first fruit - the TWS/1, reviewed here…

  • Europe pursues unified Russian gas payment response as supply threat eases

    European capitals have been on alert for a disruption to gas imports for weeks as Putin seeks retaliation over the West sanctioning Russia for invading Ukraine. A crunch point appeared to be in the offing when Moscow issued a decree on Thursday requiring foreign buyers of Russian gas to open rouble accounts in state-run Gazprombank from Friday or else risk being cut off. The Kremlin said on Friday that it would not immediately turn off gas exports to Europe, as payments on deliveries due after April 1 come in the second half of this month and May. With weeks left before bills are due, governments in Europe - which relies on Russia for more than a third of its gas supply - were talking to their energy companies about how to pay them. “Working closely with Member States and operators…

  • Extreme air pollution hampering India’s solar electricity generation

    Atmospheric pollution reduces solar power generation because it both absorbs and scatters the Sun’s rays, as well as leaving deposits on solar panels that reduce their efficiency. A study carried out by IIT Delhi calculates that between 2001 and 2018 India lost 29 per cent of its solar energy potential as a result of atmospheric pollution - equivalent to an annual loss of £635m. As of March this year, India had only reached the halfway mark of 50 gigawatts of installed solar capacity, according to the research group, Mercom India. “Put simply, aerosols - which include fine particulate matter, dust, mist and fumes suspended in the air - significantly reduce incoming solar radiation in what we call the ‘atmospheric attenuation effect’,” said study author Sagnik Dey. “This needs to be factored…
