11720158 Takahiro Yoshida Explainwhat is ocean tidal energy and how it can be used.
What is ocean tidal energy • The tide Rise and fall of ocean’s surface that we call “tide” The difference between “low tide” and “high tide” in japan. A low tide A high tide
What is ocean tidal energy • Causes of “the tide” The tide is created by gravitational tugs from the moon and sun. Moon Earth The ocean moves by gravitation of the moon Ocean
What is ocean tidal energy • Causes of “the tide” The tide is created by gravitational tugs from the moon and sun. High Tide At full moon or new moon, ocean pulled to moon and sun At half moon , ocean pulled to moon Low Tide
What is ocean tidal energy Tidal energy has very big energy. This is because a large quantity of seawater has potential energy by gravity Used for generation It is ocean tidal power plant
Structure of tidal power plant 1. At low tide Ocean side Reservoir side Generator Generator At high tide, reservoir side seawater flows into ocean side. And a generator is starts.
Structure of tidal power plant 2. At high tide Ocean side Reservoir side Generator Generator At high tide, ocean side seawater flows into reservoir side. And a generator is starts.
