Once upon a time, home computers were low-powered enough that they barely needed any cooling at all. An Amiga 500 didn’t even have a heatsink on the CPU, while the …read more Continue reading How Water Vapor Makes Smartphones Faster
We’ve studiously avoided any mention of our latest interstellar visitor, 3I/Atlas, on these pages, mainly because of all the hoopla in the popular press about how Avi Loeb thinks it’s …read more Continue reading Hackaday Links: August 17, 2025
Imagine cooling your building with the same principle that kept Victorian-era icehouses stocked with lake-frozen blocks, but in modern form. That’s the idea behind ice batteries, a clever energy storage …read more Continue reading The Coolest Batteries You’ve Never Heard Of
Although hot tubs may get all the glory, cold-plunge tubs are the ones that really help reduce muscle inflammation and soreness after exercise. The Snowcap tub makes that process more doable than ever, by chilling water without using any ice or refrige… Continue reading Cold-plunge tub chills water – and users – without ice or refrigerants
We’re caught in a vicious circle of facing increasing temperatures across the planet, and combating that with air conditioning – which in turn causes global warming. A problem worth throwing a whole lot of science at, if there ever was one.Continue Rea… Continue reading 48% efficiency boost brings eco-friendly air con a step closer
When it comes to keeping cool on hot days, it’s not so much a matter of wearing less clothing as it is a matter of wearing the right clothing. A new fabric coating could help in that regard, and it’s essentially made of chalk.Continue ReadingCategory: … Continue reading Cooler clothing may sport a snazzy matte white chalk coating
Nissan has demonstrated a new automotive paint that can drastically cool a vehicle parked in direct sunshine. Tests have shown that treated cars stay up to 21.6 °F (12 °C) cooler than untreated cars parked side by side.Continue ReadingCategory: Materia… Continue reading Nissan’s new paint cools cars by up to 21 °F in direct sunlight
Artificial-turf sports and playground fields may be more durable and require less maintenance than those covered in natural grass, but they also get very hot during warm weather. Scientists have devised a natural method of cooling them – and the cities… Continue reading Sports fields could cool cities via rainwater stored beneath turf
Whether you’re working outdoors or just taking a leisurely stroll, keeping your cool on a hot and sticky summer day can be a struggle. But a new Kickstarter campaign may have just the thing for a quick but lasting cooldown.Continue ReadingCategory: Wea… Continue reading Koojack vest keeps you cool when you’re running hot
Researchers have found a surprisingly simple way to build cryogenic coolers that reach near-absolute zero up to 3.5 times faster, or using about 71% less energy, than current gear. That’s big news for anything requiring seriously low temperatures.Conti… Continue reading Cryo-cooling breakthrough slashes the energy cost of serious cold by 71%
