That plant is subject to regulations. The xAI turbines have evaded regulations by claiming that they are portable.

You're not very off the the mark. To add in that extra detail, xAI is using portable gas turbines that are meant for providing emergency backup power in case of a catastrophic loss of power, like in the event of a natural disaster. Being portable, they lack the systems necessary to avoid polluting the surrounding air with oxides of nitrogen and formaldehyde - really nasty stuff. That shouldn't normally cause a serious issue, since the turbines are meant for temporary backup alone. But at Memphis, xAI is stretching the meaning of 'temporary'.
