harnessing water flow to drive turbines and electric generators
Tidal power is harnessed by constructing a dam across the mouth of an estuary or a bay.
Tidal power operates by damming the mouth of a river or other water source that leads into the ocean. When the tides come in (tides are created by the gravitational pull of the moon) the dam lets water flow through. At the peak of high tide the dam is closed until the peak of low tide. Then the dam is opened and turbines are powered by the water flowing out into the ocean due to the water level difference. To learn more about how tidal power works check the related link.
A dam used for tidal power is called a barrage. Such dams exist in a number of places: Rance River, in France Bay of Fundy, in Canada Kislaya Guba, in Russia Other barrages are under consideration. See the related link, below, for more information.
The tidal wave came during the earthquake and hurrican. Many people died in Flordia. Tidal Waves come from water.
There is amazing power in the ocean tides moving in and out every 12 and a half hours. The energy in the moving water turns turbines to generate electricity.There are two types:The barrage dam type, which works like a hydro-electric river dam, excepts it holds the water back at high tide and then generates power by releasing the water.The tidal stream system, which is simpler, cheaper and less harmful to the environment, consisting simply of turbines in the stream of moving water.

Because - the 'usual' function of a dam is to turn the movement of water into electrical energy. If there's no water flowing through the dam - the dam cannot produce power.
No. Tidal power cannot causeearthquakes. Unless the dam got bombed orsomethinglike thatearthquakes
Hydroelectric power
Can we produce power (electricity - www.powerfromgravity.com) from gravitaitonal (not from dam) force by using buoyancy from renewable source of energy?
yes
Four multipurpose dam were constructed during 1948 to 1959- 1- Maithon Dam 2- Panchat Dam 3- Tilaiya Dam 4- Kunar Dam
The Mullaperiyar Dam is constructed over the headwaters of the Periyar River in Kerala, India.
Hoover Dam.

Most power plants produce several Megawatts of power. A Megawatt is one million watts.
