The pollution issue isn't really possible to solve without using a proper power plant with a tall stack on each unit.

The portable gas turbine units are already very efficient and have surprisingly good emissions controls. Especially the aero derived variety. The problem is dumping the exhaust at ~ground level. This can create hotspots of nitrogen oxides. Especially with so many units running at once. If you exhaust at 100'+, the chances of hazardous accumulation are negligible by comparison.

There's really no clean way to do this fast. You typically need FAA approval to build a stack that would be tall enough to be effective. The best hope for local residents is a rapid crash sometime soon.
