Do you think it is possible to place generators on ocean currents?

The main problems of ocean physical energy, such as wave energy, ocean current energy, tidal energy, ocean temperature difference and salinity difference energy , are two: low power density and harsh ocean environment. Low power density requires very large or numerous equipment to collect energy, but the marine environment is harsh, including corrosion problems and storm impacts, hence the cost of large equipment. size in terms of structural strength, anti-corrosion and resistance. the prevention of biological adhesion is very high. Large quantities make maintenance difficult and hardly profitable. Tidal power is relatively promising because it can use the topography of the bay reservoir to enrich energy density (but is very sensitive to topography).phy and sediment) and can use large-scale cross-flow hydropower units with mature technology. It should be noted, however, that areas rich in tidal energy, such as certain bays (such as the famous Bay of Fundy) and estuaries (such as the northern branch of the Yangtze estuary in China) are themselves of great ecological importance, it There are therefore but also environmental concerns.
