Power engineer shares 'correct' method to use fans cools rooms down much faster
Most UK homes are designed to keep the heat in which makes getting to sleep in the summer especially tricky - one expert has shared the right way to use a fan to help cool down a room much faster A power and cooling engineer has shared the 'correct' way to use your fan to ensure a room cools down much faster and more effectively. As the warmer summer weather continues, and looming heatwaves remain on the forecast, many people are eager to find methods of keeping their homes as cool as possible. Most UK homes aren't equipped for rising temperatures as they're often designed to keep the heat in. Air conditioners still aren't a common feature in many homes, so many turn to using a fan and keeping it going all night long in a bid to get some decent sleep in the sweltering heat. Lots of people look to social media on a quest for answers or tips on better methods to reduce the temperature at home. And one woman caused a stir after sharing a tip from her partner, who works as a power and cooling engineer, on TikTok. In the simple six second tip, a fan can be seen in front of an open window. Over the top of the footage, the woman added the words: 'When he says if we point the fan out the open window, it will cool the room down quicker and he's right'. In the caption accompanying the clip - which has racked up more than 162,000 likes so far - the woman simply penned: 'That's on living with a power and cooling engineer'. Hundreds of people shared their thoughts in the comments section. One person said: 'Bernoulli's principle - fast moving air sucks in even more surrounding air. So pointing it out the window (at a distance) will draw a lot of the air in the room out the window with it'. Another joked: 'Why am I learning more on TikTok than I learned in school?' Someone else shared: 'We only have AC in the living room, that's what we do to redirect the cold into the bedrooms. I thought my boyfriend was crazy too when he said it but it works." Les Roberts, energy expert at Bionic, commented: 'Opening opposite windows or doors allows air to flow through. For even better airflow, you can place a second fan facing inward at the opposite opening to pull cooler outside air into the room, creating a strong cross-breeze. 'Positioning the fan to face outward pushes the hot indoor air outside, which helps draw cooler air in from the other opening.' Les continued: 'This method works best when it's cooler outside than inside - usually in the evening, overnight, or early morning - as the temperature difference creates a natural flow of air. 'The temperature gradient enhances the movement of air, allowing the fan to more effectively push hot air out and pull cooler air in, resulting in a more comfortable indoor environment. 'This approach is energy-efficient and can significantly cool your living space without air conditioning by exchanging hot indoor air for cooler outdoor air through natural ventilation enhanced by fans. It's a simple trick that could make a noticeable difference, especially at night, when outdoor temperatures drop.' On the topic of air conditioning, Roberts added: 'On average, portable air-conditioning units cost around £8.40 to run per day, whereas a fan could cost you as little as 71 pence. 'By utilising a fan to its full advantage with this hack and forfeiting air con, households could save nearly £55 a week.'

RHINOSHIELD Launches CircularBlue™: A Groundbreaking Marine Debris Cleanup Initiative
TAIPEI, June 12, 2025 /PRNewswire/ -- RHINOSHIELD, the global leader in sustainable phone accessories, proudly announces the launch of CircularBlue™, a pioneering marine debris cleanup initiative designed to combat ocean pollution. As part of RHINOSHIELD's broader sustainability platform, this initiative reinforces the brand's commitment to creating a circular, waste-free future through innovation, design and environmental stewardship. Each year, more than 12.7 million tons of plastic enters our waters, endangering marine life, coral reefs and the global food chain. Alarmingly, 80% of floating waste washes ashore within a month, often in coastal areas neglected by conventional cleanups. CircularBlue™ is RHINOSHIELD's bold response: a scalable, low-energy system designed to target these high-impact zones and drive long-term environmental change. According to Eric Wang, RHINOSHIELD co-founder and CEO, "Plastic pollution is the heavy legacy left by decades of human neglect and abuse. Through CircularBlue™, we are facing this challenge head-on — from coasts to rivers — using bold innovation and scalable solutions to clean up the past and protect the ocean's future." Anchored up to 3 kilometers (approximately 1.86 miles) offshore, the CircularBlue™ platform is a modular, autonomous, three-part system composed of: Solar-powered Floating Platforms that passively collect debris using water jet propulsion based on Bernoulli's principle AI-enabled Scout Drones that detect and signal the location of waste GPS-guided Surface Vessels that retrieve debris in active collection mode The platform's autonomous, energy-efficient design allows for continuous operation in high-waste coastal zones and includes onboard labs for water-quality testing, ecological research and environmental education. Technology Meets Circular Thinking: True to RHINOSHIELD's circular-design philosophy, the plastics collected through CircularBlue™ will be reintegrated into the company's manufacturing cycle — transforming waste into durable, recyclable consumer products and supporting broader circular-economy goals. Built to Scale: From Experimental Project to Global Solution: The platform's prototype — named ChangeMaker Wave Breaker — was developed over 18 months, with an initial hardware investment exceeding $2 million. It reflects RHINOSHIELD's transformation from an accessory manufacturer to a materials-technology lab and, now, a pioneer in marine waste management solutions. Using a blend of fluid dynamics, solar energy and automated collection, the system showcases how industrial design and sustainability can merge to tackle one of the planet's most pressing environmental challenges. It also aligns with RHINOSHIELD's ambition to transform cleaned marine waste into resources, contributing to a truly circular economy. Sustainability at RHINOSHIELD's core: CircularBlue™ extends RHINOSHIELD's longstanding commitment to reducing environmental impact, including: CircularNext: Taiwan's first fully circular phone case, made from recycled SolidSuit phone-case materials RHINOLOOP: A closed-loop program enabling product reuse and recycling Sustainable packaging: Eliminating more than 56 tons of single-use plastic annually and replacing it with FSC-certified paper and vegetable-based inks From product materials to large-scale marine interventions, RHINOSHIELD redefines sustainability by engineering solutions that are both physically resilient and environmentally responsible. "Like our journey over the past 12 years, CircularBlue™ is built on creativity, resilience and a belief that sustainability can be both bold and collaborative," added Wang. "Together with partners around the world, we can restore the ocean we all cherish." RHINOSHIELD invites environmental organizations and technology leaders to collaborate on expanding this platform globally — to restore ocean health, protect biodiversity and reshape the future of sustainable innovation.
