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 Winds of Whoopie The Winds of Whoopie Steve Martin's The Winds of Whoopie, a.k.a. simply The Winds of Whoopie, was a 1983 one-hour comedy TV special on NBC, produced and written by Steve Martin.
