Ocean currents: New source of renewable energy
Ocean currents, a source of energy that is gonna add up to the list of renewable energy sources in the years to come. Turbines placed beneath the ocean are able to rotate with the help of forces acting upon them, such as breaking waves, winds, tides caused by gravitational pull of sun and moon. These spirals developing beneath are able to generate mechanical energy that makes turbines to rotate, which cuts the magnetic flux. According to Faraday law, whenever a conductor is placed in the region of time changing magnetic field an EMF is induced into the conductor. This results in current in conductor which is valuable.
