I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
AI on laptops has created a new kind of battery problem. The promise of on-device AI processing, where the work stays local rather than routing through a cloud server, is genuinely useful for anyone handling sensitive data. But running a neural processing unit alongside everything else a laptop already juggles accelerates battery wear in ways…
Camera batteries are one of those accessories that photographers never think about until something goes wrong. They’re small enough to vanish into the bottom of a bag or a jacket pocket, common enough to own several of and regularly mix up, and important enough that losing one mid-trip can force an early stop to a…
Wireless gaming headsets have carried a quiet contradiction since they first appeared. Cutting the cable was supposed to mean more freedom, but the moment the battery dropped, you were plugging back in anyway, tethered to a wall or a charging dock and waiting. The industry’s answer has been to push battery life further with each…
Battery anxiety has become a familiar part of modern daily life. Smartphones, wireless earbuds, tablets, and handheld gaming devices all run down faster than most people expect, and the window between a full charge in the morning and a dead battery by mid-afternoon keeps shrinking. Portable chargers exist precisely to solve that, but most of…
Redwood Materials has laid off around 135 employees, or roughly 10% of its workforce, as it restructures to better accommodate its growing energy storage business, TechCrunch has learned. The cuts come just five months after Redwood cut 5% of its workforce, and three months after it closed a $425 million funding round that boosted the…
Venture capitalists have placed increasingly bigger bets on AI startups, investing over half a trillion dollars into the sector over the last five years. But these days, the smartest AI investment might be in energy, according to a report by Sightline Climate. Researchers found that up to 50% of data center projects that have been…
Modern homes depend on electricity for everything, from fridges and routers to medical devices and central A/C. Storms, rolling blackouts, and grid hiccups trigger a familiar scramble for flashlights and ice bags. Food spoils, devices die, and working from home becomes impossible. Most backup options either feel like camping gear with a couple of outlets…
Most homes accumulate a drawer full of dead AA and AAA batteries, and the uneasy feeling of tossing heavy little cylinders into recycling or the trash. Alkaline cells are marketed as single-use, even though the chemistry can often be coaxed back to life with the right kind of intervention. RegenBox 1 is a small, hands-on…
Your home is quietly bleeding energy right now. That Wi-Fi router humming in the corner, the TV on standby, the microwave clock glowing in the dark. They’re all drawing power even when you’re not using them, creating what’s known as “phantom load.” But what if there was a way to capture all that invisible waste…
Tesla is a business built, in part, on government regulations and incentives, from a Department of Energy loan guarantee in 2009 to the regulatory credits it sells to other automakers, which have driven a third of its $32 billion in profits since 2012. Now, the company’s energy business — a rare bright spot amid faltering demand…
