A few questions on the power tower;
1. What exactly is the heliostat field multiple?
2.According to SAM help, the fossil dispatch mode/setting of fossil fill fraction should be in the power cycle page but can't seem to find any such option
3.Is the receiver set to external by default,looks like there aren't input parameters for cavity type
4.Is there any reference or indicative value of fossil back up cost ($/kWe) assuming you're using natural gas?
5.For the tower fixed cost,any indication on how this would vary with height?
