hey i made this mod turbines ++ ,which utilizes 750°C and 900°C steam for a more efficient power output.
Feel free to chek it out - since i think u could maybe add a boiler which supports that?

Neat mod, but I think adding new boilers for that is beyond the scope of this mod.

I did look in to adding superheaters for reactors but there's no convenient way to give an efficiency boost without messing up the neat reactor:boiler ratios unless I make changes to the existing entities, which I do not want to do.
