OK very crude first sketch let me try to explain and you tell me if it sounds remotely workeable.
Likemany other eco nuts after the holy grail of energy, I'm trying to brainstorm a low cost solar CHP system. I'm of the opinion that passive solar is always going to win on a BTU/$ collected and...
Ok not a great title, but let me try to explain the idea.
Imagine that you have say a parachute attached to the top of a flag pole. In the center of the parachute a hole is cut and connected to a plastic tube that goes to the ground. When the wind comes up the parachute exerts a drag on the...
angl_gk,
Thanks for the welcome to PF. I'll have to recalculate using ideal rankine cycle and state point enthalpies. I agree with your superheated calculation, but I think that the nonsuperheated cycle is overestimating it, because that steam is saturated and you do not actually know the...
Thanks for the replies ank_gl and Q_Goest,
ank_gl,
How did you come up with those efficiency numbers? Here is my method, first off for the non superheated cycle I'll assume my T_low=550 Rankine (R) and my T_high=600 R. Then using carnot efficiencies as a limit and assuming that my actual...
Ok bear with me as this sounds a bit bizarre, especially for a first post. For a while I have been thinking of how to take advantage of the fact that a black passive solar collector can collect low temp BTU's at low costs, but due to the low temperature it can not be utilized in a steam cycle...
