  Using water is cheaper and easier. That is all that stop your idea from being IRL.

    well the Chinese already use co2 turbines irl so idk what you’re going on about

  shouldn’t it boil so that it can expands and makes pressure to move a turbine?

  why use energy to make a counter pressure

    Supercritical phase, it still changes pressure with heat, but there’s no abrupt phase transition. This increases efficiency somehow.

  different tool for a different purpose. water has a large heat of evaporation which is something that allows for more compact turbines

    sCO2 turbines are like 1/30th the size of an equivalent steam turbine.
