Generating electricity from sea waves

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.
