- The GM Steam car did 700*F*. At high superheats, steam is a terrific
- corrosive agent. 800C is really pushing the envelope of steam plant
- technology. You can't use leathers as rings at that temperature. Such
- dry steam is no longer it's own lubricant and you have to develop special
- oils complete with separators and high pressure injectors. Nasty complex
- problems.
