3.3. Wave energy
Oscillating water column (OWC) may be an economic method
to harness wave energy in Malaysia compared with other wave
devices as illustrated in Fig. 8. The wave energy in the Straits of
Malacca and South China Sea may possibly be harnessed using
OWC devices. Air turbines are used almost exclusively by the
OWC type wave energy devices for converting fluid power into
rotary-mechanical power [49]
