Burning gas always creates stuff you don't want to be breathing. These small portable turbines were allowed to run dirtier than a full-size NG plant because the premise was that they are small and temporary. But then xAI put 40 of them in a parking lot and fired them all up at the same time, which is quite illegal but xAI also controls the government of both Tennessee and the USA, so residents are fucked.

You hear AI folks including Trump's AI Tsar David Sachs frequently promoting what happened in Tennessee as the future of AI power generation. They're calling it "behind the meter" power generation. Understand that this is what it is: generating gigawatts of power with dozens or hundreds of "small" gas turbines all stacked in one place. Instant, on-demand toxic triangle coming to a data center project near you.
