GM teams up with Redwood Materials to power data centers with EV batteries

techcrunch.com Tim De Chant 2025-07-23 15:00:00

GM is sending new and old EV batteries to recycler Redwood Materials, which then repurposes the packs for stationary energy storage, the two companies announced today. Second-life batteries from GM have already made their way through Redwood’s process and into a 12 megawatt microgrid at the company’s Sparks, Nevada, headquarters. Electricity from that installation then flows to a nearby 2,000 GPU data center owned by Crusoe. The microgrid is part of Redwood’s new energy storage division that l

Amogy raises $80M to power ships and data centers with ammonia

techcrunch.com Tim De Chant 2025-07-27 08:00:00

From tariffs to the recent reconciliation bill, climate tech startups have been grappling with a rapidly changing landscape. Brooklyn-based startup Amogy has managed to avoid turbulence induced by U.S. politics by keeping its sights on more promising foreign markets. Amogy’s ammonia-to-power tech and its focus on Asian markets, including Japan, South Korea, and Singapore, has helped it land a fresh $23 million in funding.

Roomba J7 Plus (Out of stock): Roomba may still be the most recognized name in robot vacuums, and that's not only because it was a pioneer in the space, but because it continues to make very good robot vacuums. The Roomba J7 Plus may not be the newest model on the block from iRobot, but it still offers solid performance.

Dyson Dyson V8 Absolute: The V8 Absolute is one of the more affordable Dyson vacuums you can buy. Normally $520 at full price, it's currently on sale for $350. That still makes it more expensive than most of the vacuums on this list. In testing, it did great on hardwood, removing nearly 98% of sand, but it didn't do as hot on carpet. The Absolute was able to remove 68.3% of sand from low-pile and 52% from midpile, falling short of many competitors, including the Levoit LVAC-200 and Shark Strato

Oldest wooden tools in East Asia may have come from any of three species

arstechnica.com Unknown 2025-08-08 23:05:05

Someone made very sophisticated wooden tools in China 300,000 years ago, and it might have been Denisovans or even Homo erectus. The digging sticks, curved root-slicers, and a handful of somewhat puzzling implements were all found at a lakeshore site called Gantangqing. They are the oldest wooden tools from East Asia so far. All the previous Pleistocene tools found in the area were made from harder material like stone, bone, or antler. But logic suggests that hominins must have prepared and use

Wooting 80HE Review: Pinnacle of Hall Effect Keyboards

wired.com Henri Robbins 2025-08-16 07:00:00

Wooting was one of the first analog keyboard brands to break into the mainstream. When the original Wooting One TKL launched, it was a big deal—optical switch technology was still new to most people, and the idea of a keyboard with hyper-fast, adjustable key actuations was both novel and revolutionary at the time. Later, when it debuted its Lekker Hall effect switch in the Wooting Two, it was one of the first companies to utilize the technology for gaming. Things ramped up in 2020 with the rele

In the middle of March 1931, Virginia Woolf wrote a polite letter to a woman sixteen years her junior. The recipient, a feminist writer named Winifred Holtby, was embarking on a book-length study of Woolf’s work. ‘I should much prefer that the book should be, as you say written impersonally, from material in the British Museum,’ Woolf wrote. ‘My feeling is that when people are alive, so much personality is bound to creep in, that it is better for the critic to keep aloof as far as possible.’ By

The European wood pigeon helped me appreciate its omnipresent city cousins

As I read more about the Columbidae, though, I came to appreciate pigeons for more than just their beauty. Their big appetites are crucial to the health of forests around the globe. Researchers observing fig trees in Malaysia once found that green pigeons consumed far more fruit than any other animal in the jungle, visiting some trees more often than all other animals combined. Most animals defecate seeds near the parent tree, but pigeons are long-distance fliers who retain seeds in their guts l

Scientists Just Solved a 14,000-Year-Old Puppy Mystery

In 2011 and 2015, two approximately 14,000-year-old pups were pulled from northern Siberia’s permafrost roughly 25 miles (40 kilometers) from the village of Tumat. Within the same layers of icy soil, researchers found woolly mammoth bones with evidence of human processing. This led some to wonder whether the “Tumat Puppies” may have been tamed wolves or even early dogs waiting around for scraps at a prehistoric butchering site.

We are talking about $80 (or more) T-shirts here, so this is valid question. I think merino T-shirts are worth the investment. They offer considerable benefits over cotton and other natural fibers, as well as synthetics. Merino offers great temperature regulation, excellent moisture wicking, and they don't smell, which means you can wear them more and don't need as many of them.
