electricity -column -turbine air sea wall chamber electricity wave sea wall air column turbine chamber wave Figure 5-3. The tide and ebb create the pressure that rotates the turbine of the structure. The use of an ocean thermal energy conversion or OTEC is another way of producing energy using the ocean water. It uses the temperature difference between surface water (25°C) and deep ocean water (5°C). The surface temperature vaporizes a low-boiling point fluid like ammonia. The vapor expands and spins a turbine. The vapor is then condensed by deep ocean water into liquid so that it can be reused.
Answer (1)
Answer:1. Tidal Power Turbine- Utilizes tidal cycles (ebb and flow) to generate electricityComponents: - Seawall - Air chamber - Turbine - ColumnProcess: 1. Tides create pressure, rotating the turbine 2. Turbine generates electricity2. Ocean Thermal Energy Conversion (OTEC)- Exploits temperature difference between surface and deep ocean waterComponents: - Evaporator (surface water, 25°C) - Turbine - Condenser (deep ocean water, 5°C)Process: 1. Surface water heats fluid (e.g., ammonia), vaporizing it 2. Vapor expands, spinning turbine to generate electricity 3. Deep ocean water condenses vapor back into liquid for reuseOTEC offers several benefits:- Reliable, constant power generation- Low visual impact- Minimal environmental disruption- Can provide baseload powerHowever, OTEC also faces challenges:- High upfront costs- Technical complexities- Limited suitable locations (tropical waters)Tidal power turbines and OTEC represent promising renewable energy solutions, harnessing the ocean's potential to reduce our reliance on fossil fuels.
