Best Window Air Conditioners 2025: 11 Picks to Cool You for Years

wired.com Julian Chokkattu 2025-10-26 20:29:35

The EcoFlow Wave 3 is not for the weak. I mean that literally, as it weighs nearly 56 pounds when attached to its 22-pound lithium battery. At 6,100 BTU cooling capacity, the Wave 3 is designed for a car, RV, tent, boat, or any space that might be either temporary or off the grid. The Wave 3 also has a slightly higher 6,800 BTU heat mode. I have a van and and a dog, so for me, the Wave 3 offers a specific type of assurance on hot or cold days. Portable doesn’t mean you can move it around a lot.

Engineering Breakthrough Opens Door to Cheap Hydrogen Power

gizmodo.com Gayoung Lee 2025-11-26 02:45:37

As an alternative to fossil fuel combustion, hydrogen fuel cells hold tremendous promise. But they’re also notoriously difficult and expensive to manage, which largely explains why we don’t see them everywhere (or anywhere, for that matter, except for a few initiatives that are “exploring” their efficiency). But that may soon change. In a Nature Materials paper published August 8, researchers announced the development of a new type of solid-oxide fuel cell (SOFC) that addresses an underlying pr

Meta previewed some of its latest virtual reality prototypes this week and plans to demo them at next week’s SIGGRAPH conference. The aim, according to Meta’s blog post, is to offer VR experiences “indistinguishable from the physical world” — something it says no present-day VR system has yet done. It wants to surpass what it terms the visual Turing test. “Our mission for this project was to provide the best image quality possible,” said Xuan Wang, an optical research scientist with Reality Lab

engadget.com Unknown 2025-11-30 16:51:32

Meta previewed some of its latest virtual reality prototypes this week, with concepts that are compelling on the specs and long on the design. Literally. The company shared some details on its Tiramisu project, dubbing it "hyperrealistic VR." This set promises three times the contrast, 14 times the maximum brightness and 3.6 times the angular resolution of the Meta Quest 3. In actual stats, that's up to 1,400 nits of brightness and an angular resolution of 90 pixels per degree. One of the goals

Deadly ‘Wet-Bulb’ Temperatures Are Smothering the Eastern U.S.

gizmodo.com Ellyn Lapointe 2025-12-19 11:00:40

An oppressive heat dome has gripped the eastern U.S. this week, prompting the National Weather Service (NWS) to issue heat warnings for nearly 170 million Americans. To make matters worse, severe humidity is making high temperatures feel even hotter. Extreme heat and humidity make for a deadly combination. The human body lowers its temperature by sweating, and when sweat evaporates, it cools the surface of the skin. Humidity slows this process down, increasing the risk of heat-related illness.
