Water+Power

The Works of Water
By: Amy Roberts, Jordan Klein, Ardi Hakimi ( Robakein)



// __**Vocabulary Terms:**__ // Tidal power- a form of waterpower taken from the movement of tides, transferred into electricity power

Hydroelectric energy- production of electic power the the gravitational force of flowing water

Current- a flow of water or electricity

Water Current- Current which is produced from either hydroelectric dam power or tidal power

Dam- a barrier which can control/stop the movement of water

Turbine- a machine for producing continuous water power, a wheel revolves with fast revolving water

Generator- an engine/ machine that turns mechanical energy into electrical energy, creates a flow of water


 * __// Traditional Steps To Creating Hydrolic Dam Power Through A Generator: //__**
 * 1) Running water flows through a dam and causes the blade of a generator to spin
 * 2) The blade is connected to a shaft and when the blade is spinning it is atachd to a shaft and it causes the shaft to spin
 * 3) Located inside the shaft are a series of magnets and foils.
 * 4) The spinning of the shaft cause magnets to spin inside the wire coils and an electrial current is produced.

**__// Steps to creating Water or Tidal power: //__**
 * 1) Wave generators, also called nodding ducks, float on the open sea.
 * 2) The waves motion makes the generators bob up and down moving the central shaft
 * 3) The central shaft is connected to a turbine causing the turbine to spin.
 * 4) Inside the turbine magnets move around inside metal coils producing energy.

​
 * __// Conservation of energy for Hydrolic Dam power: //__**
 * 1) In step one gravatiational potenial eneregy of the water is transferred into kinetic energy of the blade.
 * 2) In step two the kinetic energy of the blade is transferred into the kinetic energy of the shaft
 * 3) In step 3 the kineic energy of the shaft is transferred turbine
 * 4) In step four the kinietic energy of the turbine converts mechanical energy into electrical energy.

In step 1 kinetic energy of the wave is transfered to the wave generators to the central shaft to the turbine and to the magnets. In step two the kinetic energy of the waves is transformed into the kinetic energy of the shafts In step three the kinetic energy of the shaft is transformed into the kinetic energy of the turbine The kinetic energy of the turbine causes magnets inside the turbine to move around metal coils producing electricity, this changes mechanical energy into electrical energy.

// **__Advantages__ There are many advantages to using Tidal power and hydrolic dam power in order to create electricity. Water power is reusable and reliable, it will never run out. Also water power does not pose any threat to global warming, water power uses natures natural powers in order to create electricity. ** //

The disadvantages of water power are that water power could cause a potenial problem towards animals. Water power would also be costly to make, it will cost a lot of money for hydrolic dams to be created as well as tidal power generators. However over a long span of time water power will make up for its original high cost to create. Another disadvantage is that water power might create possible flooding on some areas of land. **
 * __Disadvantages__

__Summary Of Water Power__ Water power is a renewable and reusable energy source. It is currently used to get less that 1% of the worlds energy power. The reason for this is because it can be costly to produce hydroelectric dam power and it is much easier to get other sources of energy such as petroleum. Despite the fact that water power is not used very often today there are plans for the earth to try and expand its dependency on water power. Water Powers advantages such as the fact that it is renewable and reusable and it will not cause an impact on the earth. Water powers advantages strongly out weigh its disadvantages as it will be costly to produce at first but over the long run it will be cheaper to produce than petroleum is to get. If the hydroelectric dams are placed properly they will also not cause an effect on marine life which is one its great disadvantages.
