How Mirrors Could Solve our Energy Problem

Saturated steam, is the most common type, it just means it's I'm equilibrium with the boiling liquid at whatever pressure it's at. All boiling water is making saturated steam. Beyond that there is super heated steam where the steam gets more heat input after boiling. And finally super critical steam, where the pressure and temperature are so high there is no phase boundary between water and gas so it doesn't really boil any more. Weird!
