SoftBank will partner with South Korea's Cosmos Lab and DeltaX to enable mass production of large-scale battery cells from the fiscal year starting next April. SoftBank Group's mobile unit said it plans to begin large-scale battery cell manufacturing at its plant in Sakai, Osaka Prefecture, to address growing power demand for AI services. SoftBank Corp. will partner with South Korea's Cosmos Lab and DeltaX to enable mass production from the fiscal year starting next April, the company said in a statement Monday. The aim is to output energy storage systems at a scale of one gigawatt-hour per year, SoftBank said, which would make it one of the largest facilities in Japan, according to data from BloombergNEF. SoftBank could scale up to a capacity of several GWh, Bloomberg reported last month.

Send the pool guy packing. One of these robotic buddies can maintain your water quality instead. Cleaning swimming pools is not fun. I learned this simple logic as a kid growing up in and around pools--it's the only way to survive summer in Houston, Texas. Four years ago, I became a pool owner myself, and I found that the rule still holds. Jumping into the pool on a hot day remains a rare treat, but if the pool is filled with leaves and dirt, that treat becomes a lot less delightful. And when the thermometer is reading over 100 degrees Fahrenheit, the thought of laboring on the pool deck, scooping out debris with a net, is downright cruel.

Will fusion power get cheap? New research suggests that cost declines could be slow for the technology. Fusion power could provide a steady, zero-emissions source of electricity in the future--if companies can get plants built and running. But a new study suggests that even if that future arrives, it might not come cheap. Technologies tend to get less expensive over time. Lithium-ion batteries are now about 90% cheaper than they were in 2013.

The Download: Early adopters cash in on China's OpenClaw craze, and US batteries slump Hustlers are cashing in on China's OpenClaw AI craze In January, Beijing-based software engineer Feng Qingyang started tinkering with OpenClaw, a new AI tool that can take over a device and autonomously complete tasks. Within weeks, he was advertising "OpenClaw installation support" on a second-hand shopping site. Today, his side gig is a fully-fledged business with over 100 employees and 7,000 completed orders. Feng is among a small cohort of savvy early adopters making serious cash from China's OpenClaw craze. As users with little technical background want in, a cottage industry of installation services and preconfigured hardware has sprung up. The rise of these tinkerers shows just how eager the general public in China is to adopt cutting-edge AI--despite huge security risks.

The souped-up G-Wiz EV has a range of 18 miles and topped 40 miles per hour. The G-Wiz, one of the earlier electric vehicles, technically seats four passengers. Breakthroughs, discoveries, and DIY tips sent six days a week. Anyone who's walked through the grounds of a music festival or even peeked into a public trash bin has likely noticed a deluge of discarded, single-use nicotine vapes. These vapes have surged in popularity, with the United Nations estimating at least 844 million of them were discarded by 2022 alone .

The inkless device works a bit like a printing press. Breakthroughs, discoveries, and DIY tips sent six days a week. Lego kits have become impressively intricate over the years, but the company really outdid itself with a 2079-piece typewriter in 2021. Part of its Ideas series, the brickmakers released the fully functioning mechanical keyboard. It's a unique and extremely well designed set, although not without its limits.

Technology Engineering Thomas Edison's failed rechargeable battery may get a second life The famed inventor's nickel-iron idea isn't suited for EVs, but it could help solar farms and data centers. Breakthroughs, discoveries, and DIY tips sent six days a week. A rechargeable battery based on technology pioneered by Thomas Edison may finally get its due. But while the famous inventor envisioned nickel-iron batteries powering the automobile industry over a century ago, researchers now believe the underlying concepts are more suited for renewable energy centers. According to a study published in the journal, a team including engineers from the University of California, Los Angeles have developed a prototype battery that recharges in seconds and withstands over 12,000 cycles of use--an equivalent to over 30 years of daily activity.
