Specific pumping power dependence on water speed and pipe diameter

Kurokawa (2006) touts the benefits of carpeting desert regions with photovoltaic cells. Essentially, his proposals differ little from those made by TREC Australia (DESERTEC, 2008). Both TREC Australia and Kurokawa recognize that Australia s deserts are perfect places for such vast power generating installations. 

The energy provided per unit surface area by PV cells during a year, Epv, year, i is given by  

For example, for generating 204 MW of electricity, as the system no. 5 in Table 89.1 demands, the area would be 1,36-10 m. The top area (section) of the 

One denotes by gev, i the rate of evaporated water per unit surface (units cubic meter per square meter and per second). Then  

Here x is the fraction of lake surface covered (x = 1 means the whole surface is covered and consequently, no evaporation occurs).
