For some grounding context: gas turbines are also century-old technology, and supercritical CO2 as the working fluid is pretty obvious and was extensively looked at in the 1970's [a] (and perhaps earlier). There's no qualitatively new stuff here; it looks more like a reopening of old and simple ideas due to shifting economics.
I'm definitely not trying to assign a pro-/con- valence on the tech—I just prefer clearly-grounded discussions, not puff pieces.
