Lower emissions could be a usefull benefit from such an application. <br /> <br />It is easy to see without complicated math that you are right about the flexibility of such a system being impaired, and also a compressor would still be necessary to get things started until there was enough heat to generate steam. <br /> <br />Also, when I had suggested designing a USC system with an unusually heavy heating chamber to provide a temporary overcapacity by a heat battery effect, I was thinking of very high temperatures, and understand that would be necessary to yield any benefit. I was thinking of possibly a ceramic material for construction if it could withstand the thermal cycling, if not then the temperature would have to be limited to some subcritical temperature for the given metal of construction. <br /> <br />Anyway, you did say this is not a problem in USC systems. <br /> <br />I guess such dialog can be part of a learning process, but a part of me feels uncomfortable making proposals that are beyond my ability to substantiate. At any rate, this is stuff that I walk around with all day in the back of my head, and I guess it can't hurt to unload. <br /> <br />Just out of curiosity, if a given amount of steam is allowed to expand and do work, then theoreticaly, shouldn't it return to a liquid state at a lower temperature and pressure if compressed, and once compressed could have heat removed more easily? It sounds very Carnot to me.
