The sheer volume of air moved by high pressure gas turbines makes that large and costly. Not impossible, but very large. These units are 2 per container size,

The sheer volume of air moved by high pressure gas turbines makes that large and costly. Not impossible, but very large. These units are 2 per container size, intake and exhaust silencers would probably increase their footprint 5-8x. Not that it shouldn’t be done, just that there’s a lot of incentive not to do it.
