This will be an interesting project. Having lived in Las Vegas for a few years I can certainly see how they expect it to work. However planting grass inside the greenhouse seems a bit much.
The plant will be limited by how much heat can be put into the air inside the 'greenhouse' and overall it will be interesting to see how the feed in replacement cool air without creating dust storms and sucking up birds and what not. I don't suppose someone with Mathematica can build up the spreadsheet using the perfect gas law and the air convection to see if their claims are close. 200MW is 200 sq kilometers of surface area at a nominal solar insolation of 1KW/meter but with an efficency of 10 - 15% and an actual insolation in AZ nearer 800W/m2 that is 1.6M sq kilometers of surface area for 15% conversion rate.
I'm wondering if they have the math they did posted somewhere.
