Hydro Power

HYdroelectric power is pretty cool and here is a diagram:

In hydroelectric power moving water turns spins a turbine. A shaft from that turbine sticks into a generator. That produces electricity. In a coal fired power plant coal heats water and steam from the boiling water turns a shaft that sticks into a generator. That makes electric power. Any source of power that can make a large shaft turn can produce electricity. The electricity comes out of the generator on wires. It goes to a power transformer. The transformer turns it into high voltage electricity. That way it can travel over transmission lines without losing energy. It is also called wholesale power. It is like a grocer who buys large boxes of cereal and cuts open the large cardboard boxes and then puts the family size boxes on the shelf to sell. You can not use this high voltage electricity. It is so powerful, it would cook you. It goes to a substation where it goes to another transformer. There is reduced in power to where it is safe to put in wires that run down the streets. Then it goes to another transformer where it becomes safe to put in the wires that go to your home.

The production of electrical power through the use of the gravitational force of falling or flowing water. It is a renewable form of energy. Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. This height difference is called the head. The amount of potential energy in water is proportional to the head. A large pipe (the "penstock") delivers water to the turbine. The spinning turbine produces the electricity.

This is called hydroelectric power, or hydro power.

To tap hydroelectricity, there must be a dam which can store water and let it flow rapidly through a sink hole. The pressure of the falling water can drive generator turbines and these will generate electricity.

Hoover Dam is the largest hydro electric dam in the world.

This Is Totally Wrong.

The Largest Hydro-Electric Dam In North America Is The Mighty Grand Coulee Dam In The State Of Washington Which Produces 3 Times The Megawatts As Hoover Dam. Grand Coulee Produces 6,809 megawatts And Hoover Dam Only 2,078 megawatts. The Mighty Grand Coulee Contains Nearly 12 Million Cubic Yars Of Concrete And Hoover Only 3,250,000 Cubic Yards. Grand Coulee Dam Contains In It's Third Powerhouse 3 Of The Worlds Largest Generators At 805 Megawatts Each. The Mighty Columbia River Flows 3 Times The Water As Does The Colorado. These Two Dams Are Not Even Close In Comparison.

There are a great many different kinds of power plants in the world. These power plants can be run by water for example.

The moving or falling water travels through a turbine, causing the turbine blades to spin.

This in turn, is used to drive a generator (in simple terms, this is a magnet that spins inside a coil of copper wire).

The rotating magnetic field produced by the spinning magnet induces an electrical current in the copper wire hence generating electricity.

no it does not cost to use Bluetooth ow ever Bluetooth is very slow on the iPhone 4

when water fiows from water resource then potential energy converts into kinetic energy. due to this water rotates to the turbines and conversion of kinetic energy into mechanical takes place . the shaft of turbine is connected to generator and in turbine due to rotation magnetic flux takesplace and electricity is produced.

Hydropower is the cheapest way to generate electricity today. No other energy source, renewable or nonrenewable, can match it. Producing electricity from hydropower is cheap because, once a dam has been built and the equipment installed, the energy source-flowing water-is free.

Although Hydropower does present a few environmental problems the inherent technical, economic and environmental benefits of hydroelectric power make it an important contributor to the future world energy mix,

Not thing it is powerful

Yes, but only because Hydroelectric generated electricity can be produced 24/7.

Nikola Tesla and George Westinghouse built the first hydro-electric power plant in 1895 in Niagara Falls and started the electrification of the world.

Hydroelectric energy is very efficient, yes? well the reason we dont use it more than we do is because hydroelectric isnt all good for the environment, or the economy.

Storage facilities can cause harm to the environment in surrounding areas. They can alter quality and amount of water flowing down the stream, which can affect plants, as well as aquatic and land based animals. Fish are killed from the spinning turbines in the river, although this can be avoided with the use of fish ladders and similar structures. Dams can block the migratory routes of fish such as salmon and others that live in the ocean, but come upstream to breed. When new dams are created, they can destroy the habitat of species in the surrounding areas, and even destroy forests. When these forests are destroyed, they produce methane, a potent greenhouse gas. C0 can also be emitted in the process of making the hydroelectric plants. Dams also reduce the flow of sediment and nutrient downstream, and they reduce the temperature of the water. These are the main arguments against hydropower.

Hydroelectric energy comes from the movement of water (the prefix "hydro-" means water.) Any transfer of energy from water movement to anything electrical or mechanical is a form of hydroelectric energy. The best examples are dams. A dam blocks moving water and forces it through a confined space, where it can do mechanical work or be converted to electrical work. Another example could be a mill wheel being used to grind corn. Yet another could be an old-fashioned paddle-wheel boat (although that's chemical energy from the burning of coal being turned into mechanical energy turning the wheel that results in the boat's forward motion.) Technically those last two examples are hydromechanical rather than hydroelectric, but you get the picture.

In permeable (porous) rock layers like sandstone.

u smoke it just like any other kind of weed :P hydro is used for many things such as computers, television, heat and many other things that you do on a daily basis. hydro is also used to cook keep you alive and it also helps you in many cases. It is used for many different things that you do.

when the water is flowing over the the dam with high velocity, it acquires great kinetic energy, when this water is used to turn the turbines, this kinetic energy will be converted into electrical energy. so, when the water flows over the dam, hydroelectricity is produced.

you get it from oceans or the hydroelectic plants will give it
