> efficiency of the generators with jet engines could be increased a lot if the heat from the exhaust gases would be recovered and used to generate extra electric power, with a steam turbine

I'm guessing most gas power plants use the combined cycle, otherwise you'd be wasting the energy of the exhaust gases. That uses a steam turbine heated by exhaust gases from the gas turbine. https://en.wikipedia.org/wiki/Combined-cycle_power_plant

Yeah, the combined cycle gas turbines are the most efficient known method of generating power. That’s been proven for a long time.

But they do have certain drawbacks, and may not be the most EFFECTIVE for a given application.

You do have to look at a long list of constraints and use cases.

And sometimes, time to market is the most critical factor so you take whatever you can get your hands on. Which xAI has repeatedly proven that they will do, regardless of the environmental consequences.
