- Now, lets not get smart, here...
-
- But does Mr. Lydick have it right?
- Would there be any advantages at all of an external-combustion gas turbine over
- an internal-combustion model?
-
- Emmisions is the only possiblity I can come up with... but if the gas
- temperatures were the same in both systems, it wouldn't really make a
- difference, would it?
-
- That settles it. 'Looks like we'll have to use a liquid.
-
- Damn.
-
- Becuase a liquid working fluid means:
- A condenser
- A bigger boiler
- Lubricant separation before condensation
-
- Can anyone explain the nessecity of this? Why does lubricant have to be
- mixed with the steam, like the book on the GM Steam Car said?
-
- I suppose that just like the best IC engines burn a _little_ oil,
- a _little_ lubricant would leak into the fluid system of a steam car.
-
- The book said that if the lubricant stayed in the water after condensation,
- the boiler would be damaged. How's that? Would the oil break down in
- the 1000 degree + boiler?
-
- Could the lubricant be separated AFTER condensation, BEFORE boiling?
-
- HELP!!!
