Under otherwise similar conditions (including equal cross-sectional areas through which the flows pass), water has far more potential for generating electricity than air because of its greater density. for example, a 5 km/hr (3.1 mi./hr or 1.4 m/s) ocean current could theoretically generate power equivalent to a 47.5 km/hr (29.5 mi./hr or 13.3 m/s) sea-level wind. additionally, from an engineering viewpoint, because the ocean currents speed and direction are variable than those of wind, the actual ocean-current generation of power is likely to be substantially greater.
