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
What to the Slave Is the Fourth of July? that slavery could be eliminated with the support of the church, and also with the reexamination of what the Bible was actually saying. You profess to believe, "that, of one blood, God made all nations of men to dwell on the face of all the earth," and hath commanded all men everywhere to love one another; yet you notoriously hate (and glory in your hatred) all men whose skins are not colored like your own.
