=WAVE ENERGY! =  -A wave energy converter transfers the rise and fall of sea waves or pressure changes from below the surface into a generator that makes electricity.  //There are different ways to collect wave energy: // - There are two types, horizontal & vertical. The movement of the buoys creates mechanical energy which is changed to electrical energy.  2) **OSCILATING WATER COLUMNS ** - This is where a water filled column generates energy. The rise and fall of water moves air or fluid which spins a generator at the top of a column to generate energy.  3) **FOCUSING DEVICES** - Channels near the shore letting waves into an elevated reservoir, then letting water flow back out, turning a turbine that generates electricity.   -The energy change is from kinetic energy (the movement of the waves) to electrical energy (from the generator)  <span style="font-family: Eurostile; mso-ansi-language: EN-US; mso-bidi-font-family: Verdana; mso-bidi-font-size: 17.0pt; mso-bidi-font-weight: bold;"> <span style="color: #e36c0a; font-family: Eurostile; mso-ansi-language: EN-US; mso-bidi-font-family: Verdana; mso-bidi-font-size: 17.0pt; mso-bidi-font-weight: bold;">-In the USA, there is a wave power park at Reedsport, Oregon. The project uses PowerBuoy technology that consists of ocean going buoys with a diameter of 4M and 16m long each. The rise and fall of waves moves the buoys creating mechanical energy that is then converted to electrical energy, which is then transmitted to the shore. They are installed about 8km offshore in water about 60m deep. <span style="color: #244061; font-family: Eurostile; mso-ansi-language: EN-US; mso-bidi-font-family: Verdana; mso-bidi-font-size: 17.0pt; mso-bidi-font-weight: bold;">-On shore, ocean wave generators may occupy extended lengths of coastline with significant wave activity. However, most of these are residential areas or wilderness. Building in these areas will be met with resistance. -Ocean environments change: storms can make small waves huge in a very short time, so a wave energy device has to be made very durable to survive harsh ocean conditions. -Wave energy systems may either be in the ocean or offshore, so the electricity has to be transferred via undersea cables which are costly both initially and when being fixed or checked. -Even in active wave areas, there are days with little activity. -The potential is enormous as most of our planet is water. -Water is capable of transferring more kinetic energy than wind power, and would therefore be more efficient. -Even small energy devices can produce large amounts of electricity. || http://en.wikipedia.org/wiki/Wave_power http://www.energy-consumers-edge.com/ocean_wave_energy.html [] [] [] []
