Tidal and Wave Power

  1. 1. Tidal Power and Wave Power How they Work<br />By Wave Power Inc.<br />
  2. 2. The Difference between the Two<br />
  3. 3. Wave power devices take energy directly from surface waves or from pressure fluctuations below the surface. Some analysts believe there is enough energy in the ocean waves to provide up to 2 terawatts of electricity. Wave power is of course powered by waves. As a wave goes by, the buoy rotates and transforms mechanical energy into electrical energy. <br />Tidal power is powered by a turbine under water that spins making the mechanical energy to electrical through a generator that send the electrical energy to peoples home stores schools and small businesses. When tides comes into the shore, they can be trapped in reservoirs behind dams. Then when the tide drops, the water behind the dam can be let out just like in a regular hydroelectric power plant. moving waves of the ocean. That energy can be used to power a turbine.<br />The biggest difference is one is on the water and the other is under<br />Differences<br />
  4. 4. There are two types of tidal power<br />Bio wave <br />Turbine <br />Bio wave is like a big flap that’s connected to the bottom of the ocean floor. Mechanical energy is generated from the wave pushing on the flap, which creates energy that is sent to a generator. The generator makes electrical energy that’s sent to homes and small businesses<br />Types of Tidal Power<br />
  5. 5. Tidal power is under water when a wave rises into a chamber. <br />The rising water forces the air out of the chamber. <br />The moving air spins a turbine which can turn a generator.<br />The turbines spinning is mechanical energy.<br />The generator converts the mechanical energy into electrical energy, which goes to schools houses and smalls businesses.<br />Tidal Power and How it Works <br />

  7. 7. Wave power is using the power of waves to make energy. <br />Wave energy is powered by waves <br />Buoys spin from the mechanical force of the waves pushing the buoys in a rotating motion.<br />Energy is generated by an electrical shaft that’s being rotated by a electric coil inside the rotating buoy.<br />Energy generated goes to houses small businesses and schools<br />Wave Power and How it Works<br />
