Yes, But it also costs approx. 1/5 capital for a gas turbine of Same MW. We will also wait to see how long 375,000 mirrors/motors last in the wind/dust swept desert
You forgot the fuel cost for cleaning mirrors with farm tractors and squeegies and pumping mirror wash water from...where? I estimate about 50 farm tractors running all month long. By the time they get all the mirrors washed it will be time to wash again :) I am also anxious to see how a utility scale boiler likes to cycle up/down with the weather/sunlight and thermal cycling will have on its lifetime. Of course I am an engineer and I have to think about these realties. Otherwise, Jed, I agree with you.
