The given diagrams depict how a machine is used to produce electricity by utilising the power created by waves.
The whole structure is built very close to the sea shores as to be able to utilise the waves as much as possible.The first step in this process shows how the waves come into the chamber. While the tide is high, the force created by the waves, pushes or channels the air through a metallic column which is set up on a cliff or a sea wall. There is a turbine inside the column. The air causes the turbine to rotate in a clockwise direction. This rotatory mechanical energy is converted to electrical energy. The electricity thus generated does not cause any pollution as it solely relies on the simple nature of the tides. This is used to power various appliances like light bulbs.
Subsequently, when the waves recede, the air moves back from the atmosphere into the chamber and thus keeps the turbine in motion. As the turbine moves, electricity is produced which is utilised by humans.

The diagrams show a structure that is used to generate electricity from wave power.
In the event of a high tide, the excess air pressure enters the turbine. These turbines are affixed to a column. These waves are made to go inside the chamber and from there, massive columns of air rotate the turbine that produces electricity. The cliff or sea wall could also be denoted as helpful since they act as barricades and help the water to get inside the chamber.
However, the situation changes drastically in the case of a low tide. When the wave goes away after hitting the cliff or sea wall, the same amount of air pressure creates a suction inside the chamber that causes the turbine to rotate in the same direction, which helps to generate electricity.
This continuous process of waves striking the cliff and retreating contributes to the maintenance of air suction pressure, which rotates the turbine to generate electricity.

The diagrams here depict the structure via which electricity is generated from wave power.
The structure seems to be built on the bank of a sea. A chamber in installed over a part of sea which starts the process, with high tidal waves towards the machine, water pushes the air and chamber retains that air within the structure to push it further towards sea wall. The air enters the the machine and aids the turbine to rotate clockwise at high speed to generate electricity.
However, when air flows in opposite direction than last scenario, the column attracts and passes the air through turbine to help it to rotate in same clockwise direction to generate electricity again only for air to push the water away from chamber this time.
In both the cases, the efficient structure generates clean, environmental friendly electricity with renewable resource i.e. air, which can flow in any direction.

The given diagrams explains that how the electricity can provide in two different ways by utilizing the power created by waves.
In First diagram, the first step is the wave enters into the chamber when there is a high tide, it releases some air pressure then the pressure which is formed by waves enters into the turbine which is fixed between columns next to the sea wall. When turbine sense air pressure, it starts rotating in clockwise direction at high speed and produces the electricity.
On the other hand, other diagram shows that the wave leaves from chamber with some air pressure, the pressure which was formed due to the downward wave it also enters into the turbine and rotates in clock wise direction at high speed to change the generated energy into electricity.
This continuous process of waves can generate the electricity by changing the mechanical energy to electrical energy using these natural resources like air, waves, energy etc.,

The given diagram shows mechanical arrangements of setup to produce electricity using wave energy.
The image-A and Image-B explain the process of generating electricity using natural wave effect of sea through rotating movement of turbine due to air inlet/outlet in the structure made of column and chamber.
As shown in image-A, sea wave coming towards cliff or seawall through the chamber causes flow of air upside in the column. Because of that the turbine which is fitted in the column starts rotating. Due to rotation of turbine the electric device which is directly connected to it, generate electric power.
When the wave goes away from the cliff or sea wall which is given in image-B, it also bring the air outside with it from the column.so, again the turbine start rotating and electricity produce by electric device. After that, the process is repeated again and again through the sea waves.

The diagrams given below depicts how electricity is produced from wave power.
Overall, figure A and B depicts the cycle of events taking place when the sea waves approach the sea wall and returns back and how this natural process is used to generate electricity.
This whole set up is generally located near a sea wall or cliff as it is the place where the waves come and goes continuously throughout the day. The set up consist of a chamber which leads to a narrow column where the turbine is located. Figure A depicts the process in which a high wave approaches the shore, enters the chamber and the positive pressure exerted by this helps in rotating the turbine which in return produces electricity.
Figure B depicts the process when the waves retreat back, thus creating negative pressure which again rotates the turbine generating electricity. So, electricity is produced both when the waves come to the shore or retreats back.

The picture portrays two events involved in the production of electricity with
the help of wave power. The first one including when the waves arrive and the latter
when they withdraw.
Initially, when the waves collide with the cliff they enter through a chamber with
full force bringing along a huge amount of air which dictates the direction of the wave
flow. As they hit the sea wall they come to a stop and the air that has carried them
moves forward and travels along with the thin columns all the way up to the turbine rotating
it in the clockwise direction. This will help pump electricity and the wind exits through
Secondly, when the air moves in the opposite direction (away from the cliff in this
event), the air enters into the narrow column where it has exited previously. Then it
turns the turbine and exits through the chamber along with the waves. The turbine is
in fact spun in the same direction in both the events.

Electricity is one of the important utilities man has ever discovered after the wheel. It is defined as the flow of electrons from one point to another in a conducting medium. The process of generating electricity usually involves a turbine, a moving medium like air or water that rotates the turbine snd a system to convert the kinetic energy into electrical energy to transmit it to the destined points.
The figures given here depict the generation of electricity from sea waves by a system constructed near the shoreline to utilize the velocity of the incoming sea waves. Figure A shows how the system works when a sea wave enters into the generating system while figure B illustrates how the system changes when the entered sea wave retreats from the system back to sea.
In Figure A, when a wave enters, it is channeled through a vertical column that contains a turbine. The wave enters the column at a high velocity making the turbine within the column rotate at the speed of the incident wave in a clockwise direction. The circulation of the air in this section will be in an upward motion. The rotation of the turbine results in the generation of electricity in the system.
In Figure B, it is clear that as the wave reaches the maximum height, it recedes back to the sea through the column by the influence of gravity. As the water runs in a downward motion, the velocity is transferred to the rotation of the turbine in the clockwise direction which results in the generation of electricity in the system. Since such systems are constructed in shorelines with frequent high-velocity waves, simultaneous generation of electricity happens.

The diagram illustrates how electricity is being generated from wave power.
We can clearly see that how location and construction is important for a Tidel Power Plant . As in this case generation of electricity possible whenever the waves enter and recede also.
The Part A depecits how electricity is being generated when the waves enter the chamber , the massive air pressure of the waves makes the turbine rotate which are affixed to the columns and generate electricity .The cliff or sea wall helps to streamline the pressure of the waves towards the turbine. In Part B ,when the waves recede ,the air pressure developed is being again used to rotate the turbine inorder to generate electricity.
Thus electricity is being generated in both inward and outward movement of the waves inside the chamber.

The diagram shows the working procedure of machine which generates electricity with the help of tidal waves and air.
The machine is build at the bank of the sea wall, as it need tidal waves and air to generate the electricity. The process in A – Diagram shows the tidal waves come into the chamber which makes the air push inside the column which it make and allow the turban rotate in clock wise direction. This rotation of the turbine generates the electricity and this electricity can be use in appliances like electric bulb.
The similar process in B – Diagram shows the tidal wave moves away from the sea wall which makes the air moves back from the chamber which make rotation of turbine in clock wise direction.
This continuous process of tidal wave in and out of the chamber make makes the turbine to rotate and the rotation of turbine leads to produce the electricity.

The Picture illustrates how electric power is produced from a structure constructed near the sea wall, where the energy from the sea tides is converted into electrical energy.
Overall, two main stages are involved in the power generation where the air, which was accelerated by the tidal waves, plays a key role in the power plant.
The power plant consists of a chamber built on the sea bed. From the chamber, a narrow column is raised on the cliff or the on the sea wall with an opening in the top for free air flow. The turbine, which is being rotated by the air is mounted inside the column.
During the high ocean wave, the tide enters the chamber, thereby pushing massive amount of air into the column in upward direction. The pressure of incoming air rotates the turbine in a particular direction. When the wave resides and moves out of the chamber, the air move in the opposite direction towards the sea, still moving the turbine in the same direction. The energy which is created by turbine rotation is in turn converted into electricity for powering equipment.

The diagram illustrates, how the electricity is generated from the sea wave power.
Overall, the structure depends on the air and water pressure which helps the turbine to rotate and produce electricity. This can be done in two stages.
According to the diagram, the whole structure which helps to produce power is placed near the sea wall. There is a curved chamber extended towards the sea and it is responsible for maintaining the air pressure in it. The Turbine which is placed between the column is connected to the bulb to test electricity flow.
In stage one, when the seawater enters the chamber, then water pressure increases and air pressure decreases due to this, the air is kicked out of the chamber through the column and helps the turbine to rotate and produce power. In the stage two, when the wave exits the chamber then, due to huge air pressure air enters into the chamber through the column with great force and rotates the turbine to produces electricity.

The diagram illustrates the process of generating electricity from a turbine near the sea wall.
In the first phase, the sea wave entered the column chamber with accumulated air, however, the forced air creates a positive pressure difference that helps to pass through the turbine in an anti-clock wise direction. When a turbine moved fast it will start generating electricity in the bank situated in sea cliff.
In the last phase, sea waves move in the opposite direction along with flowing off atmosphere air through the column in the same direction. This process of producing electricity is seasonal depending upon the high air pressure in sea waves. The idea of producing light through a renewable source of energy is highly effective and cost-friendly.

The given diagram illustrates how water energy is harvested into electrical energy with the help of a turbine which rotates as air moves in and out of the column .
The appropriate location for the structure is a cliff or a sea wall near a water body with waves. Further, the structure is built in such a way that whether the waves move into the chamber or away , it will cause the turbine to move and produce electrical energy .As water moves into the chamber air is pushed out of the column causing the turbine to rotate ,also when wave leaves the shore air is sucked into column again causing the turbine to move ,hence producing energy in the process .
To summarise this structure uses clean energy and coverts it into electrical energy which can be used to light bulbs or for other purposes.In comparison to using coal for production of electricity this is a far better and cleaner alternative for source of energy.

The two diagrams illustrate how a specifically designed man-made structure is used to generate electricity from the force of the wave.
This structure consists of a wide chamber along with the long column consisting of the turbine.It is directly erected on the sea wall where it is subject to the movement of the waves.
The first diagram shows how the ocean waves are entering the chamber forcing the air to move upwards in the column.Here due the pressure of the air the turbine starts rotating which in turn helps in the generation of the current of electricity. The process does not stop here and this structure continues to produce power as the waves move out of the chamber.
As the ocean waves move out of the chamber the air comes down resulting in the rotation of the turbine once again and hence there is the continuity in the generation of the electricity.This process continues and the electricity is generated.

The figure shows the structure which generates electricity from wave power.
Here from figure A, we can understand that the electricity is produced when turbine is rotated. A turbine is a instrument which converts mechanical energy into electrical energy by movement of rotor around its shaft. In this figure, the mechanical energy is generated by motion of waves which indeed causes movement in turbine. the turbine is rotated by exerting the air pressure inside that chamber. As the wave enters it dislocates the air inside the chamber to move through the column obviously the pressurized air rotates the turbine with immense force. More the rotation greater the power generated.
In figure B, we can observe that when the wave flows out off the chamber eventually it creates a void space for air to flow back into the chamber. the turbine is again rotated due to the movement of air into of the chamber. On comparing both the figures we can understand that movement of air in and out of the chamber which is basically caused by wave power causes rotation on the turbine. Subsequently, the electricity is generated as the turbine has kept on constant rotation.
Hence, This is image depicts the basic analogy of generation of electricity using wave power.

The given diagrams depict the process of electricity generation by utilising the power of waves.At first glance,it can be perceived that when the waves move inside the chamber or leave it ,there is a movement of air in the column which leads the production of electricity.
To begin with,the structure is set up near seashore or is mounted on a cliff. It basically consists of a big chamber, one side of which is open to the sea through which the water waves enter and leave.Apart from the chamber,it has a vertical column in which a turbine is installed.One end of the column is open to the atmosphere due to which the air moves freely bidirectionally.
Initially the chamber is empty,but as the time goes by the waves enter the chamber due to which the air starts moving upwards through the column ,and subsequently the turbine starts rotating and ultimately electricity is generated.
On the contrary,the movement of the air is in the opposite direction when the waves depart but the turbine rotates in the same direction as earlier(i.e,clockwise) and eventually electric power is generated again.
So,in this process current is generated in both the cases,i.e,arrival and departure of waves.

The given diagram depicts the production of electricity by a model which uses wave energy. Overall, the mechanism of electricity generation depends on the direction of wave in the chamber. The structure is constructed along the cliff or sea wall and constitutes of an air column, a rotating turbine, a chamber and an electricity producing unit besides the turbine. The column is a narrow cylindrical passage which connects chamber (the largest sub-structure) to the environment.
When a sea wave proceeds into the chamber, there is movement of air from the chamber into the column from where it exits into the atmosphere. This outward movement of the air leads to clockwise rotation of the turbine thus producing electricity.
On the other hand, when wave recedes from the chamber, outside air is sucked into the column and then into the chamber, again rotating turbine in the clockwise direction and this further leads to generation of electricity.

@fal please review
The diagrams illustrate the process which is used to generate electricity from sea wave.
From the figure it seems that whole structure is built on cliff or sea wall and electricity generates with the help of turbines, sea wave and air.
As shown in diagram A, when the sea wave comes through leakage free chamber to generate pressure which is further opposed by the air coming through column, as water pressure is much higher than air pressure it forced air to move backwards due to this turbine rotates in clockwise direction with gradually increasing speed and generates electricity.
However, the water wave is move backwards after some time because inclination of cliff or sea wall which allows air to come through columns with increasing speed as shown in diagram B. Now the pressure of air is more than pressure of water wave which help turbine to rotate with increasing speed which helps to generate electricity.
VimyMemberMarch 2, 2022 at 9:48 AM
The diagram shows how electricity is generated through wave power.
The figure ‘A’ depicts that we can generate electricity from high tide wave with the help of cliff or sea wall. As we can see here, when a wave hit the sea wall or cliff seems it creates an air pressure which goes into upward direction in the long passage denoted by column and moves the turbine anti-clockwise, due to this mechanism an electricity is generated.
On the other hand, in figure ‘B’ the situation changed drastically, when there is low tide, here when wave hitting the sea wall goes away, the process change its direction in downward direction creating an air pressure to go back towards the wave which makes the turbine move into same direction. This process helps in generating electricity.
Overall, the process of suction into chamber and retreating back with the help of sea wall or cliff which acts as a barrier to create this suction. Thus, this mechanism helps in generating electricity from wave power.

The following diagram depicts the process of producing electricity with the help of waves.
Overall, the above figure explains the process in two parts where the first one explains generation of electricity when waves move in an upward direction and the other part describes the production of electricity when waves moves in a downward direction.
In figure A, waves come from downward to upward direction through the chamber. After that these waves go through the column. Then these waves rotates the turbine which is there is the column. In the end, the electricity generates with the movement of the turbine.
Similarly, In figure B, waves passes through the chamber but in this cases waves come from upward to downward direction. The waves then rotates the turbine which is situated between the columns. Finally, with the help of the movement of the turbine, electricity is generated.

The above diagram shows a structure that is used to generate electricity from wave power. The diagram shows a comparison of two depictions which shows movement of a wave, in and out of the machine.
Overall, electricity is final outcome in both depictions, showing the process by which electricity is produced with water wave, air pressure and turbine in the chamber.
In the first illustration “A”, the water wave enters the chamber with the motion flow of the water and pushes air towards the turbine inside the chamber which rotates with the force of air, the electric device connected to the column, stores the electric energy produced in the process.
The second illustration “B” shows the water wave exiting the chamber with the external vacuum of the wave and again the turbine is moving in the same direction due to the suction of air by the water wave while leaving the chamber, which produces electricity in the same fashion.

The given map illustrates the generation of electricity with the help of wave movement.
Overall, the electricity is generated by the wave moving towards and away from the turbine. These waves cause the air to flow in and out of the column and make the turbine to rotate continuously in same direction. Finally, the rotational force of the turbine generates electricity.
Firstly, the wave moves inside the slope chamber which makes the wave to push the air trough column in upwards direction. The motion of air rotates the turbine inside the column in clockwise direction. Due to the continuous rotation, the coil inside the turbine contacts the generator right next to it and produces electricity.
Secondly, the wave moves away from the chamber and causes the air to move reverse direction inside the column. Due to both existing clockwise rotation of turbine and downward movement of air flow causes the turbine to rotate in same direction.

The diagrams A and B show how the turbine uses both air and water to generate power.
In the Image A the electricity generates with water in the same direction of the air flow by the use of turbine whereas in the Image B the flow of air and water are in reverse direction and rest the factors are same in the both pictures.
However, the electricity generates in the two ways by the hydro power plant. First of all refer to the Image A which consist of the parts such as column, turbine, water waves and the sea wall, in which the turbine fits into the column and that can be rotated in the clockwise direction, and the wave comes from the sea it strikes in the turbine from the same direction which turns to generate the electricity, by which the lighten up the bulb.
Although in the Image B turbine fits into the column same as the Image B but the direction of the Air & water which are reverse to the turbine directions( Anticlockwise) and it still generates the electricity. Even though the area of the sea wall in both the pictures are same location which is left of the Column that facilitates the support of the columns in both the situations.

The diagram illustrates a structure that is used to generate electricity by process of wave power.
In the first event, the air is flowing towards upward direction coming out of the column, causing the wave to flow through chamber and forcing turbine to move and produce the electricity
However, in the later case the air is moving towards the opposite direction and causing wave to flow away from the chamber and creating a suction above sea level, resulting the turbine to move again and produce the electricity with same efficiency.
It is clear from both the diagram that this setup for producing electricity is useful in both cases whether air flows inwards or outwards through column.
