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 The Situations and Names of Winds The Situations and Names of Winds (; ) is a spurious fragment traditionally attributed to Aristotle. The brief text lists winds blowing from twelve different directions and their alternative names used in different places. According to the manuscript version of the work, "The Situations and Names of Winds" is an extract from a larger work entitled "On Signs" ("De Signis") likely written by a pseudo-Aristotle of the peripatetic school. "Situations" is notable as an ancient text which reproduces the concepts of the Anemoi or "wind gods" and classical compass winds, both of which have
