Old hat to many (hello Shannow) I'm sure but the GE 9HA gas turbine got my interest today as I was coasting around the interwebs. The thing is behemoth. About a half a gigawatt per each, that's some electrons brother. Apologies for plowing old ground here but these things amaze me. 64% net efficiency, Wow (combined cycle but still, Wow). Any guesses as to how much a single installation costs?

Probably (!) pretty durable, GE offers 21 year service agreements.
As an aside, I recall my grandfather telling how his plant shipped the best steam turbines in the world to the USSR during WWII as part of the aid package. The Russians have bought a 9HA too but I can't guess how many pieces of it have been (non)destructively "tested" since then. Putin threatening us with nuclear war in the last few days (he likes to frighten the Europeans ahead of things like the G7) reminded me that Lenin was right. We never learn, we will sell our very best to those who would harm us. It's our version of fighting with one hand tied behind our back. But caution to those who would take advantage - we still tend to win even in that configuration.
Definition of geek - finds curve of turbine blade oddly appealing.
Cheers, sorry for the tangent.
