The below graph shows part of a spreadsheet that calculates the sum of radiation area and collector area for a 75% efficient Carnot engine running between 1400 deg K and the radiator temperature on the X axis of the graph.  The number must be multiplied by two for kW on the ground after a 50% transmission loss.  The spreadsheet is available from the author, hkeithhenson@gmail.com.
