Ocean Current

The utilization method for ocean current energy is to generate the electricity. Its theory is similar to the hydropower. Any hydropower plant can be rebuilt as the current power generation plant. But since the density of seawater is about 1000 times to air, and the plant should be put under the water, the current power generation exists a serious of key technology problems, including the installation and maintenance, power distribution, anticorrosive, loads under the marine environment and safe performance. Furthermore, the current power generation plant differs a lot with the hydropower plant in the fixing method and turbine design. The current power plant can be fixed to the seabed or the bottom of floating body, which can be anchored to the sea. The turbine design on the current is also a key technology.
