Tidal Power Chris Webber
Tidal power is dependant on tides created by the moons gravitational pull on the earth
Potential • Places with highest tidal range Bay of Fundy, gulf of Kutch in India
Types of Tidal Power Generation • Barrages • Tidal Streams
Tidal Barrage • Turbines • Sluice gates • Embankments
Benefits • Renewable • Can help protection of ports in storms • Can help navigation for shipping • Reliable, more so than solar or wind
Environmental factors • Change in currents • Change in sediments • Salinity and quality of water • Migratory species
Tidal streams • Instead of damming estuaries the tidal currents are harnessed using wind like turbines
Main methods of current generation • Marine current generator • Stingray • Tidal fence
Benefits of Tidal stream • Far less intrusive • Can generate same amount of power as wind with smaller blades moving slower due to density of water • More available sites • More reliable than wind • Usually less expensive than barrage
Problems • Fouling • Relatively new technology • Don’t get the funneling effect of barrages
