Thanks for the perspective. The reduced size is also dwarfed by however the CO2 is being heated. If by concentrated solar field of many acres, than the size of the turbine doesn't matter on its own. What matters is if the reduced size leads to reduced complexity/cost/maintenance burden.

There are different methods for concentrating the solar light, some of them are able to achieve only lower temperatures, for which it is more efficient to use organic Rankine cycles (i.e. like the steam turbines, but instead of using water some organic fluids, which are similar to those used in air conditioning or in refrigerators, are used in closed cycle), while other methods, e.g. the solar towers, can achieve higher temperatures that are suitable for supercritical CO2 cycles (e.g. up to 1000 Celsius degrees).
