> Power generation turbines are designed to work at ambient sea level conditions. They don't rely on ambient air being especially cold for cooling, they can keep cool thanks to the large mass flow rate

What could be contributing to this is recently Vertasium did a whole video on how jet engines operate at temperatures above their components melting point.

And how the cold air at altitude is what keeps it from melting.
