Eyre North and South monthly evaporation rates

For each of these macro-engineered components (i.e., covering the lake, ducts and pumping) there are two obvious associated costs  

The duct cost increases by increasing the pipe diameter, as expected. Obviously, it depends on the tensioned duct material, with composed fabric the least expensive solution. The same feature exhibits the cost of installing the duct, but in this case the dependence on duct diameter is weaker. The cost of the pumps comprising the pumping installation decreases by enlarging. However, it is obvious that the larger contribution to the macroproject cost is provided by covering Lake Eyre. 

The cost of the duct, the PV cells and of the electric pumps enabling steady seawater shifting, are estimated. The cost Cduct of the conducting tube is given by  

The cost of the pumping installation, Cpump, is obtained from  

The cost cpv of the PV cells is obtained from the cost per Watt of the PV cells, C(pv,w), and the total installed power
