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.

The Slovak state then became Protectorate of Bohemia and Moravia

Just a small correction: Slovak state became nominally independent and the Czech part became the Protectorate.

Passenger information systems in public transport. Some might run some kind of embedded windows, but most run on Linux. Certainly here in Czechia, but I believe it's common at east throughout the Central Europe.

Followed by Propaganda accounts having shower thoughts not about Tiannamen Square.

Lemmygrad seems to be full of tankies and has been here for a long time...

Czechia has a racism problem sure, but that map has no data on actual Eastern European countries so there is no comparison possible. Also you can't reduce the question of being Eastern European on one metric. Was Belgium under Leopold II. Eastern European? Nazi Germany? USA before 1863?

Please do not refer to Czechia as Eastern Europe. It' simply wrong: Czechia rejected the Eastern Christianity even before the Great Schism, it never was a part of the Russian Empire and it spent most of the last millennium as a part of the HRE. The only connection - being part of the former Eastern block was so long ago that in only 4 years Czechia will be a EU member longer than it was occupied by the USSR.
