An Experimental Investigation on A Simple Direct-Drive Wavepower Generation System Utilising an Oscillating Water Column
This study investigates the performance potential of a simple direct-drive wavepower generation system utilising an oscillating water column (OWC). The OWC was selected due to their ability to operate in places with low wave power density, low wave height, and shallow water. This is owing to the fac...
