Studies on Wave and Tidal Power Extraction Devices

Electric power from wave and tidal power is a form of pollution free and echo-friendly renewable energy which has a huge potential. This potential has not been realized high capital costs and environmental concerns. This paper discussed how the two problems could be resolved utilizing small scale technologies, innovative financing, and involving local communities of the coastal areas to ensure that all key impacts are manageable. Bangladesh has 710 km long coast line and long coastal area with 2~8 m tidal head/height rise and fall, most of which is protected against flooding by embankment and sluice gates. Therefore, the potential for wave and tidal power in the country is significant because the barrages necessary for creating controlled flow through turbines (to tap tidal power) are also needed for flood control. The wave climate has been studied for a long time at the coastal belt of Bangladesh. It has been shown that it is feasible to generate electricity using the Bay of Bengal. Our research study showed that all twelve months of the whole year are not feasible for wave and tidal power production but 8 months of the year (from the late March to October) are most suitable, feasible and viable for power production
