Teams are losing parts of text chat conversations for me. Not sure if that’s issue of their PWA on Linux or just an issue in general…

You are discussing on a platform created by a man who praises people like Lenin & Castro. Richard Stallman resigned over some comments on Epstein victims. Free software is like that sometimes.

Compare that to the turbine in a coal or gas plant, which can archive up to 90% efficiency.

Nope, you might have seen 90+% efficiency when talking about steam power plants, but that’s the efficiency of the generator(converting the mechanical energy of the the rotating turbogenerator to electricity). You have to multiply with the efficiency of the turbine(converting the energy of the heated gases into the mechanical energy) and there the efficiency is much lower, ~40% for a coal fired and maybe <60% for a gas combined cycle.
