Elon Musk’s xAI faces second lawsuit over toxic pollutants from datacenter

A picture


Elon Musk’s artificial intelligence company xAI is facing a second lawsuit alleging it is illegally emitting toxic pollutants from its enormous datacenters, which house its supercomputers and run the chatbot Grok,The new pending suit alleges xAI is violating the Clean Air Act and was filed Friday by the storied civil rights group the NAACP,The group’s 40-page notice of intent to sue alleges xAI has been polluting Black communities near its facility in Southaven, Mississippi,The pollution comes from more than a dozen portable methane gas generators that xAI set up without permits, the notice alleges,The NAACP’s first notice of intent to sue was filed last June and involves similar allegations regarding the company’s datacenter in Memphis, Tennessee.

In order to file a lawsuit under the Clean Air Act, parties must file an intent to sue notice at least 60 days prior.The NAACP’s case in Memphis did not progress toward a lawsuit after xAI obtained permits for its generators there.“As we shared when xAI began its operation in Tennessee, this illegal pollution only exacerbates complications to frontline communities who continue to bear the brunt of environmental injustice,” said Abre’ Conner, the NAACP’s director of environmental and climate justice.“We cannot allow for companies to promise a better future while pumping harmful chemicals into the air we breathe.”xAI set up its first datacenter in Memphis in the summer of 2024.

It’s a massive facility, roughly the size of 13 football fields, and named “Colossus”.The company has since erected a second, even bigger datacenter named Colossus 2 in Southaven.The building of a third xAI datacenter, also in Southaven, just got under way last month.Southaven is in the Memphis metropolitan area, but located just over the state border in Mississippi.Community members in Southaven have complained about the noise and pollution coming from Colossus 2.

They’ve also circulated a petition demanding accountability from Mississippi regulators.The NAACP’s suit in Southaven is intended to challenge xAI’s use of unpermitted turbines.The group alleges that the company has 27 generators without permits at this facility, and it has documented more than a dozen of them being in use since last fall.Separately, a Guardian investigation published on Friday found that xAI has moved in 27 portable turbines at Colossus 2.Using thermal imagery, the Guardian concluded that 18 of those generators have been used since November.

These types of gas generators emit fine particulate matter that contains hazardous chemicals like formaldehyde and nitrogen oxide.These pollutants are tied to an increase in diseases, like asthma, respiratory illness and certain cancers.The NAACP says that xAI’s 27 turbines in Southaven have the potential to emit a “staggering amount” of nitrogen oxides, likely making the facility the largest industrial source of the chemical in the metropolitan area.Mississippi state regulators say the turbines fall under a loophole and don’t require permits because they are portable and temporary, which is how regulators in Tennessee first dealt with xAI’s generators there.But the Environmental Protection Agency maintains that such pollution sources do require permits under the Clean Air Act.

“xAI has once again built a polluting power plant without any permits and without any notice to nearby communities,” said Patrick Anderson, a senior attorney with the Southern Environmental Law Center, which is working with Earthjustice to represent the NAACP.“There are no loopholes or exceptions – xAI is breaking the law while leaving local communities to deal with the consequences.”If the intent to sue notice proceeds to litigation, the NAACP said, it is seeking injunctive relief, civil penalties and costs to cover attorneys’ fees.xAI did not respond to a request for comment.

AFL State of Origin return was no kick and giggle but spectre of injury hangs over its future | Jonathan Horn

Even for the most sceptical, there was never any question that the quality of skill in the State of Origin’s return game would be exceptional. There were three Brownlow medallists, two Coleman medallists, 29 All-Australians and 19 premiership players. Patrick Dangerfield and Max Gawn had 16 All-Australian blazers between them, more than the entire Western Australian squad combined.The doubt lay in how hard the players would go, and how seriously they would take it. How much would they be willing to risk? And how far down the well – in the middle of a Perth summer and with no serious game time in the legs for nearly five months – were they prepared to go?The game was heavily marketed, and backed with a lot of money from the WA government

Afterwards they had been so disappointed they had drowned their sorrows in the pub.But, on a glorious sunny day in Livigno, everything clicked for Team GB as Bankes overtook France’s Léa Casta on the final turn to win gold ahead of Italy, who came through to win silver, and France 2, who won bronze.Incredibly their victory meant it was also the first time that Britain has ever won two gold medals at a Winter Olympics

India beat Australia in rain-hit first women’s T20 cricket international – as it happened

Gah, we’re done here folks. The rain is still falling and has kiboshed India’s chase. They were sitting pretty at 50-1 in the sixth over. Shafali Verma looked particularly ominous, crunching two sixes (the only ones of the match) in her 21 before Molineux snared her with her very first ball as captain.Plenty to ponder for Sophie Molineux though as Australia don’t get that new captain bounce, quite the opposite

2025 NFL predictions revisited: Seahawks blindsided us, but we were right about Jets

We didn’t see Super Bowl LX coming, but some of us were early believers in Ben Johnson’s Bears, Trevor Lawrence’s Jaguars and the fallibility of the ChiefsIt doesn’t take long for the egg the start dripping from our faces. The early September headline accompanying our 2025 NFL predictions – Will it be Mahomes, Jackson or Allen in the Super Bowl? – was the ultimate hedge. After all, what were the odds that one of them wouldn’t emerge from the AFC?Then there was the reality. Mike Vrabel’s dramatic turnaround of New England. The Bears transforming from worst-to-first in the NFC North under Ben Johnson

Winter Olympics briefing: Pinheiro Braathen writes Brazilian fairytale

Hundreds of thousands of international tourists are expected to descend on Brazil over the next few days for carnival. But you didn’t need to go further than the Dolomites on Saturday to see somebody performing samba on a raised platform.Lucas Pinheiro Braathen entered Brazilian sporting folklore by snaring his country’s, and continent’s, first medal at a Winter Olympics – and a gold at that. The reigning champion, Marco Odermatt of Switzerland, who leaves these Games without a title after being fancied for multiple successes, was no match for Pinheiro Braathen in the men’s giant slalom in Bormio.Brazilian TV heralded this moment by overlaying on to its coverage the same music that ran alongside Ayrton Senna’s grand prix victories in Formula One
