Marine current power the rotation of the earth. The sun acts as the primary driving force, causing winds and temperature differences. Because there are only small fluctuations in current speed and stream location with minimal changes in direction, ocean currents may be suitable locations for deploying energy extraction devices such as turbines. Other effects such as regional differences in temperature and salinity and the Coriolis effect due to the rotation of the earth are also major influences. The kinetic energy of marine currents can be converted in much the same way that a wind turbine extracts energy from the wind, using various types
The Situations and Names of Winds been historical components of western culture. "Situations" is the shortest piece traditionally attributed to Aristotle as part of the Corpus Aristotelicum, occupying a single two-column page (973) in Bekker's standard reference edition of Aristotle's complete works. The twelve winds, described in order in the text, are: In addition to these primary names, the document also gives partial information on other traditional names for the same winds, and geographic associations tied to various places. Although the document usually provides geographic context as opposed to cardinal directions, it is clear by comparing its scheme to other classical accounts that the listing starts
