2. What is it? It is a form of Hydroelectricity that turns tides into electricity It is a predictable, clean, and reliable energy source Used since 787 A.D.
3. How does it work? The energy of the tidal waves can be harnessed by Mechanical to Electric energy in many ways.
4. Barrages Barrage: When the water levels on both sides of the barrage are significantly different (7m), gates are opened, allowing water to flow through and power the turbines. This also the most common way to harness tidal power
5. Turbines Tide turbines: this is similar to a wind turbine but placed underwater. They are placed where the currents are moving fast like a mouth of a river. This is used in sea water because it is more dense which will move the turbines faster.
6. Tidal Reef It is similar to a barrage but does not disrupt the movement of water as much. It will allow fish that migrate to pass through and will allow mud flats to be exposed in low tide.
7. Push Plates These plates are in a chain and connected to a oval-shaped channel. When one plate gets pushed from the tide of a river, it hits another plate and with this motion it powers a generator.
