Abstract :
Renewable energy is such a hot topic today that not only do articles appear in science journals but intelligently written articles concerning this subject also appear in fashion, celebrity, and weekend periodicals. Within this topic are many different solutions being researched and developed to solve the problem(s) of finding a source of enery that is renewable, sustainable, and profitable. Among the most popular are solar pv cells, wind turbines, wave and tidal turbines, nuclear, and even petroleum products derived from daily grown algae. Of all of these, only one solution offers a resource that spas nearly seventy one percent of the earth´s surface [1], about 361,300,000 km2, of the oceans of the world. The earth´s oceans contain two types of energy-thermal energy received from the sun and absorbed by marine waters, and the kinetic or mechanical energy of moving water: such as waves and tides. Tides are caused by the pull of the moon´s gravity field and its distance from earth´s surface. Waves on the surface of the sea are formed by winds that blow across the ocean imparting their motion and direction. Strong winds and those that last over long distances cause larger and more powerful waves, which are the type of waves that I hope to capitalize on.
