Power plants, may develop based renewable energy that exists in all coastal areas. Mareomotriz energy is an energy with more useful than other renewable energies such as wind, Solar. This tidal energy is similar to the energy, wind and hydraulic energy, that turns mechanical energy and then .in electric power, that is the solution for the entire planet. The sea moves all the time, that mechanical energy reaches the shores of beaches does not know how to use it, and all the continents are surrounded by sea, the mechanical energy that is more powerful. Solution of all our problems, this conversion is what I know, not is that more want. My name is Pedro Vargas peruvar@hotmail.com
