Breaking AI & Tech News Analyzed

Why Fans Are the Smart Summer Cooling ChoiceThe Guardian’s award‑winning tech journalist measured 16 fans and several evaporative coolers to see how they perform against a typical portable air‑conditioner that draws 1,000W (about 26p per hour). Fans in the test consumed between 8W and 60W, delivering a far lower electricity bill and carbon footprint while still moving enough air to make a noticeable temperature drop.Power Consumption Numbers Show Fans Beat Air‑ConditionersAirCraft Lume – 18W on top setting; could run 56 hours for the cost of one hour of air‑con.Dreo TurboCool misting fan 765S – 22W, best overall cooling performance.Devola desk fan – 12W, cheapest at £64.99.Shark FlexBreeze Pro Mist – 30W, premium misting option at £249.99.Swan Nordic evaporative cooler – 15W, lowest‑energy water‑based cooler at £69.Cooling Comfort Meets Carbon Savings for UK HouseholdsRunning a fan instead of an air‑conditioner can cut summer electricity use by up to 95 %, translating into lower bills and reduced greenhouse‑gas emissions. For a typical UK home, swapping a 1,000W air‑con for an 18W fan saves roughly £23 per month and avoids about 0.12 tCO₂ of emissions.What’s Next for Home Cooling in a Warming Climate?As heatwaves become more frequent, manufacturers are likely to focus on quieter, smarter fans with integrated sensors that adjust speed automatically. Expect more hybrid designs that combine low‑energy misting with airflow optimisation, giving consumers a wider menu of carbon‑friendly cooling solutions.

The British Solving Championship: An Opportunity for Chess Enthusiasts This week’s puzzle is a chance to enter an annual national competition in which Guardian readers ­traditionally perform well and in ­considerable numbers. White in the diagram, ­playing as usual up the board, is to play and checkmate in two moves, against any black defence. The Event Details The puzzle is the first stage of the annual Winton British Solving Championship, organised by the British Chess Problem Society and sponsored by the investment ­managers ­Winton. This competition is only open to ­British ­residents and entry is free. To take part, simply send White’s first move by post to Nigel Dennis, Boundary House, 230 Greys Road, Henley-on-Thames, Oxon RG9 1QY, or by email to [email protected]. Entry Requirements and Deadline All entries must be postmarked or emailed no later than 31 July 2026. Entrants must provide their name and home address. Juniors under 18 on 31 August 2025 must also give their date of birth. The Competition Structure The best 15-20 players from the postal round, plus the best juniors, will be invited to the final at Harrow school on Saturday 13 February 2027, where the prize money is expected to be at least £1,600. The winner of the final will have the right to represent Great Britain at the 2027 world ­solving championships, an event where GB are often medal contenders. A Note on Chess and Professionals Back in the 1950s most top English players were amateurs, often civil servants or teachers, who competed in tournaments during their vacations. After the 1970s Fischer boom and English successes brought an influx of sponsors, chess professionals could earn a decent living, but the tide turned again during the 1990s. The breakup of the Soviet Union brought harder international competition, while Nigel Short’s world title defeat and the move to screen rather than print marketing drove sponsors away. A New Grandmaster: Harry Grieve Harry Grieve became England’s latest grandmaster on Tuesday when the 25-year-old, who was British champion in 2022 and helped CSC/Kingston finish second in this season’s UK 4NCL League, won first prize in Budapest with a 7/9 total.

The Inevitable Relegation West Ham's relegation to the Championship has been confirmed, a bitter pill to swallow for the London club. Despite a convincing 3-0 victory over Leeds, the team's fate was sealed by Tottenham's win over Everton. This marks a disappointing end to the season, with the club's struggles on the pitch reflecting a deeper malaise. The Executive Failure The root cause of West Ham's downfall lies in its executive leadership. The club's ownership, led by David Sullivan, has been criticized for its complacency and lack of vision. The team's failure to adapt to changing circumstances and improve its performance has led to this point. The Financial Implications The financial implications of relegation are significant, with estimated losses of £100m in the first season alone. This will likely lead to job losses and a reduction in staff, as well as a decrease in the club's overall value. The Way Forward As West Ham looks to the future, it is clear that changes are needed. The club will likely undergo a period of restructuring, with potential changes to its management and playing staff. The appointment of a new manager and the departure of key players, such as Jarrod Bowen and Mateus Fernandes, are already on the cards. A New Era for West Ham? The relegation of West Ham presents an opportunity for the club to rebuild and rebrand itself. With a new approach and a renewed focus on developing young talent, the club may be able to recover and return to its former glory. However, this will require a fundamental shift in its approach to the game and its relationship with its fans.

Phyllida Barlow's Disruptor Exhibition at Wolterton Hall Phyllida Barlow's exhibition 'Disruptor' at Wolterton Hall in Norfolk is a thought-provoking showcase of her unconventional sculptures and installations. The exhibition challenges the traditional grandeur of the stately home, transforming it into a space for contemporary art. The Exhibition's Concept and Curation The exhibition is curated by Simon Oldfield, Wolterton's artistic director, who has reinvented the space to make room for new ideas. Barlow's works, which seem to take on a life of their own, are a perfect fit for this vision. Her exhibition begins at the entrance with the installation 'Untitled: Stacked Chairs', a cacophony of red plywood chairs that feels like a statement about throwing things out and starting again. Barlow's Sculptures and Installations Throughout the exhibition, Barlow's sculptures and installations are displayed in various rooms of the stately home. Her works are made from unconventional materials such as latex, cement, hessian scrim, plaster, and rope. One of her early works, 'Loaf', is a tar-black glass and paper coated with latex, resembling a loaf of bread. Her recent wall sculptures, cobbled together with cement, hessian scrim, plaster, and other materials, look like big gobs of bubblegum stuck rudely to the wall. The Impact of Barlow's Work Barlow's work is about what materials communicate. The house says, 'I am here, I'm important – Barlow says, everything is precarious, nothing goes as planned.' Her works are a commentary on the impermanence of things and the challenge to traditional notions of art and architecture. The Future of Wolterton Hall The exhibition is part of Wolterton Hall's ongoing transformation into a space for contemporary art. The hall's owners, the Ellis family, have been working to reinvent the space, and Barlow's exhibition is a key part of this vision. The exhibition runs until 31 October and is a must-see for anyone interested in contemporary art and the transformation of traditional spaces.

The Unconventional Auction Artists Hilary Powell and Dan Edelstyn are auctioning off their work from the past decade and a half to help fund a community-led renewable power station in Nigel Farage's Clacton constituency. The big-ticket item going under the hammer will be the remnants of a gold Ford Transit van containing £1.2m in fake banknotes that the pair blew up in London's Docklands in 2019. The Blown-Up Van The van wreckage and charred banknotes were gathered up and reconstituted as an Alexander Calder-like mobile that, for a while, hung in Cambridge's Fitzwilliam Museum. Now, for perhaps £100,000, this sculpture could be the centrepiece of your living room. Powell hopes that the exploded van will be bought by a public institution. The Fundraising Goal The pair hope to raise at least £250,000 for the project. Alongside the in-person auction, they are hosting an online iteration that will run until 31 May. They currently have £750 and need about 250 times that to fund the project. The Purpose Behind the Project The pair call what they do Method Art. They aim to build a community-owned renewable power station in Reform's first seat as a response to the party's donations from oil and gas interests, highly polluting industries, and climate science deniers. The Future of Community-Owned Renewable Energy The proceeds from the auction will bankroll the work the pair are doing to set up in Clacton and to make a film about the project. If they sell the blown-up van, the proceeds will be core funding for their not-for-profit production company. The funding for the power station will come from issuing shares and other fund-raising to create a community benefit society.

The Lead The Museum of Homelessness in London is hosting an exhibition titled 'Criminal: An Untold Story of Homelessness, Resistance and Survival', which explores the criminalization of homeless people and nomadic communities over the last 400 years. The Exhibition's Powerful Message The exhibition features an installation by Romany Gypsy poet, performance artist, and journalist Gemma Lees, which includes a trim caravan with china decorated with Sun newspaper headlines criticizing Gypsy and Traveller encampments. The installation highlights the stark contrast between the cozy interior of the caravan and the harsh realities faced by nomadic communities. The History of Criminalization The exhibition takes visitors on a chronological journey through the history of criminalization, from the Egyptians Act of 1530 to the 2022 Police, Crime, Sentencing and Courts Act. It showcases how laws have been used to marginalize and criminalize homeless people and nomadic communities. The Impact on Homelessness London is currently facing a record high level of homelessness, with over 13,000 people sleeping rough in 2024-2025, a 10% increase from the previous year and a 63% rise over the past decade. The exhibition aims to raise awareness about the issue and provide a platform for discussion. The Future of Homelessness Support The Museum of Homelessness not only serves as a museum but also provides community support and acts as a cold weather shelter in winter. The exhibition 'Criminal' is a timely and powerful reminder of the need for better solutions to address homelessness and the criminalization of vulnerable communities.

The Timeless Allure of Tosca Gustav Mahler hated it, and its publisher was convinced it would be a commercial disaster. Critics complained it was mostly just 'noise' and predicted it would quickly be forgotten. But more than 125 years since Tosca's premiere in January 1900, Giacomo Puccini's fifth opera remains one of the most bankable in the business. The Opera's Turbulent Beginnings Puccini's work was initially met with skepticism. Mahler dismissed it as 'papal pageantry with continual chiming of bells.' The problem in 1900 was precisely that Puccini wove 'real-world' sounds of bells and screams, cannonfire and religious chant straight into his score. It was a groundbreaking example of an immersive soundscape, but for some, those sound effects were radically out of place in an operatic work of art. The Data Behind Tosca's Success Over 125 years since its premiere, Tosca remains a popular opera. It is known for its melodic appeal and gripping plot. The opera has been performed in numerous productions worldwide. The Impact of Tosca on Opera Tosca's enduring appeal lies in its combination of overwhelming melodic appeal and a sex-and-death nail-biter of a plot. US director Ted Huffman suggests that 'It's also a study of evil, which we find really entertaining in a horrible way.' The opera's themes of state violence and resistance are particularly relevant today. The Future of Tosca Productions Despite its popularity, there have been few bold reimaginings of Tosca. Most productions stick to the traditional setting in Rome. However, Huffman's new production at Glyndebourne, inspired by 1940s neorealist Italian film, offers a fresh take on the classic opera. The production explores realism and its relevance to today's world.

The Birth of a Classic The Mekons and Gang of Four emerged from the same fine art course at Leeds University. After being inspired by the Clash and the Sex Pistols, the Mekons formed and recorded their first single, 'Never Been in a Riot', on a two-track tape recorder in a living room. The Making of 'Where Were You?' For their song 'Where Were You?', Bob Last from the Fast Product label helped them record at Spaceward in Cambridge. The song came together quickly with Kevin Lycett strumming two chords, Tom playing a choppy counter-melody, and Jon on drums. Mark White wrote the lyrics, and Andy Corrigan sang them. The Impact of 'Where Were You?' 'Where Were You?' became a huge success, selling over 27,000 copies and receiving significant airplay from John Peel. The song gained even more popularity when David Bowie compared the Mekons to T. Rex on a Radio 1 programme. The Legacy of 'Where Were You?' The song has remained a classic, with the Mekons still playing it live almost 50 years later. The song's lyrics, influenced by Buzzcocks' Pete Shelley, deal with themes of loneliness and feminism. The Mekons' decision to include women in the band and their anti-macho approach to music set them apart from other rock bands at the time. The Song's Enduring Influence 'Where Were You?' continues to have an impact, with the song being used in an advert for Honda's Acura cars and generating a substantial amount of money for the band. The Mekons' story serves as a testament to the power of creativity and perseverance in the music industry.

The Legacy of the White Hotel The White Hotel, a Salford venue housed in a former MOT garage, has been a generator for underground culture in the north-west for over a decade. Its programme has spanned classical music ensemble the Manchester Collective, a celebration of Bertolt Brecht, and Andy Weatherall's last ever DJ set. The Event Details The White Hotel will shut up shop in January due to its location in a flood-risk zone. The venue's artistic director, Austin Collings, and caretaker, Ben Ward, decided it was better to close on their own terms rather than risk becoming a museum. The Data Analysis The White Hotel has hosted sold-out gigs from notable acts such as Damo Suzuki and William Basinski. The venue has a 300-capacity space that was overwhelmed by a 2015 gig with Detroit legend DJ Stingray. The Impact Analysis The White Hotel's closure will erase a rare club built from the ground up, fueled by a spirit of experimentation and collaboration, disregarding the profit motive. However, its spirit will mutate, and the team behind the venue are celebrating its legacy with a new three-day festival, the Black Lights, in venues around Blackpool. The Prediction The team behind the White Hotel are launching a film production company, with Collings' directorial debut, a short titled Wild Bodies, set to go on the festival circuit with a soundtrack by the Coral. The future of the Black Lights festival is dependent on ticket sales, but it aims to continue the White Hotel's legacy of experimental and underground culture.
