Window-mounted air conditioning with a view

With record-breaking temperatures looming ahead like rippling walls of heat from sun-baked asphalt, it behooves one to check that air conditioning units are in proper working condition ahead of time. For those considering an upgrade, Philadelphia-based Likuma Labs has unveiled a new product that addresses the frustrations experienced with many window air conditioners. Noria is designed to be smaller, lighter, and quieter, while offering full-room circulation and smart connectivity.Read More

A powerful desktop PC that's completely silent? CompuLab's Airtop uses natural airflow to make it so

When you hear that a machine is fanless, you'll probably also assume that it's not extremely powerful, likely relying on mobile-focused components that don't pack much of a punch compared to high-end desktop gear. CompuLab's latest desktop PC, the Airtop, challenges that preconception, offering 200W of completely silent passive cooling, allowing for powerful CPUs and full-size graphics cards.Read More

First liquid-cooling laser could advance biological research

In a world where lasers are sci-fi's weapon of choice for melting away an enemy spaceship (sometimes even translating to the real world), researchers at the University of Washington have swum against the current and produced the first laser capable of cooling liquids. The technology could be especially useful for slowing down single cells and allow scientists to study biological processes as they happen.Read More

Transparent coating keeps solar cells cool and efficient throughout the day

Stanford engineers have developed a transparent silicon overlay that can increase the efficiency of solar cells by keeping them cool. The cover collects and then radiates heat directly into space, without interfering with incoming photons. If mass-produced, the development could be used to cool down any device in the open air for instance, to complement air conditioning in cars.Read More

New "smart window" material selectively blocks light and/or heat

In an effort to improve the energy efficiency of building, researchers have sought to develop windows that change transparency to let more light – and therefore heat – through when it's cold, and less when it's hot. Unfortunately, these methods tend to impede the passage of visible light, some by tinting panes and others by complete obscuration. But a team at the Cockrell School of Engineering at The University of Texas at Austin has developed a "smart window" technology that allows the passage of visible light while blocking heat, or vice versa.

Coated polymer stack promises to keep your roof cool in summer

Of all the scenarios you'd want to find yourself in a heatwave, being barefoot on a hot tin roof would be toward the bottom of the list. These exposed surfaces soak up sunlight to slowly but surely transform into corrugated hotplates, compounding the sweltering ambient temperatures and warming the living space below. But a team of Sydney-based scientists has developed a new material that's claimed capable of keeping a rooftop cooler than the air that surrounds it, saving energy and sweating residents in the process.Read More
