Engineering teams are repurposing retired aircraft engines stored in Arizona's Sonoran desert to rapidly supply electricity for booming artificial intelligence facilities. These converted turbines burn more fuel than modern gas-fired power plants, leading to heightened emissions of hazardous air pollutants. For example, Elon Musk's xAI installed eight converted turbines to run a Mississippi data center under high-emission permits. The site now faces legal challenges from environmental lawyers over air quality standards and alleged undercounting of emissions.

At a time when the artificial intelligence (AI) boom has sparked a surge in electricity demand, American AI data centre companies are finding new ways to power their infrastructure. While some are turning towards massive solar and wind farms, others are striking deals to use nuclear power to keep the servers running. Now, they are reportedly turning to Arizona’s Sonoran desert where thousands of retired airplanes with jet engines mounted sit in vast metal graveyards. Those turbines are being resurrected to keep the servers running. The New York Times reported that a growing roster of engineering firms is stripping engines from decommissioned aircraft and converting them into stationary electrical generators with data center operators snapping them up as fast as they can be built.

“They’re getting creative. Just a few years ago, a traditional data center would have been like, ‘Are you kidding me? This is ridiculous’,” said Bill Kleyman, chief executive of AI platform and infrastructure provider Apolo. Today, attitudes have fundamentally shifted around project lead times. Data center developers are now singularly obsessed…
Popular content creator Kyle Thomas is joining veteran presenters Chris Packham and Megan McCubbin on the new year-round wildlife series *Naturewatch*. Produced by the BBC Studios' Natural History Unit, the programme aims to engage younger demographics and combat social media misinformation by providing reliable factual programming about British wildlife. The broadcast focuses on accessible outdoor nature and will feature interactive segments to directly connect with audiences.
The trial rollout addresses fierce domestic competition in Apple's Greater China market, where Western systems like OpenAI and Google cannot operate due to data sovereignty rules. By securing regulatory approval through a local partnership with Alibaba, the tech giant aims to modernize its ecosystem for more than 110 million compatible devices. However, local rivals are aggressively fielding their own artificial intelligence features, tempering expectations for a decisive commercial edge.
The collapse of the multi-billion-dollar enterprise hardware agreement marks a significant intervention by the Trump administration to restrict Chinese access to cutting-edge computing technology. By stepping away from the long-term computing arrangement with Tencent, the US enterprise software firm demonstrates the mounting geopolitical risks facing commercial cross-border tech partnerships. The move directly curtails international infrastructure expansion while aligning corporate operations with federal geopolit…
