What happened
The xAI "Colossus" supercomputer facility in South Memphis allegedly runs 33 methane-powered turbines, despite a permit for only 15. The turbines reportedly power AI training for Grok. The facility's massive energy use and alleged unpermitted turbines reportedly produce extreme nitrogen oxide and formaldehyde emissions, adding toxic smog to a predominantly Black neighborhood already burdened by pollution and health risks.
Editor's notes
Reported timeline of events: (1) 06/05/2024, it is reportedly announced that xAI will begin constructing and operating Colossus, a massive AI supercomputer facility in a predominantly Black neighborhood in South Memphis. (2) Throughout 2024 and into 2025, reports emerge that the facility is running 33 methane-powered gas turbines despite having permits for only 15, reportedly producing large volumes of nitrogen oxides and formaldehyde without public notice or pollution controls.
