Aswan Dam

The problem:
The Aswan Dam has a surface of 5000 km2 with an annual production of 1010kW.h.
Suppose you want to replace the dam production by solar cells whose yield is 14%. The average sunshine is 290 days per year with an average power of 900W/m2.

a) What area of solar cells would be needed to achieve the same production with "solar" (solar cells)?

For 2570 kW.h / year requires an investment of 14,000 € (for individual house). Search the price of equivalent facility for the production of the Aswan Dam? Is it very expensive ? (read the American Nobel Prize Joseph Stiglitz in Economics)

c) Calculate the power dam in Watt?

This series of booklets propose a simple physics problem. Each book consists of a context to introduce the subject of physics problem and its solution in the form of video (screencast).
