Abstract
We propose a new method to generate electricity by either harnessing the motion of a rotating fan or harnessing the wind energy produced by the rotating fan. This electricity is used directly or is stored in battery banks to be used later to give basic lighting using LED's or to run small devices such as radio, mobile battery chargers, etc or other devices as per our requirements. We propose a new system to generate electricity by either harnessing the motion of a rotating fan or harnessing the wind energy produced by the rotating fan. When the fan is in motion we couple it with a generator or use small blades which are rotated by the wind generated by the rotating fan. This in turn produces electricity which is stored in a battery bank. This stored energy is later used to run LED lighting providing us basic lighting or small devices such as radio or charging mobile phone batteries etc irrespective of the fan being 'ON' or 'OFF'. During motion of the fan, the energy produced can be used directly for running LED lights or small devices via a full wave bridge rectifier circuit. Ceiling fans, table fans, exhaust fans and similar devices can also be coupled to our system.
Description
FAN FOR POWER GENERATION - A NEW TECHNIQUE FOR HARNESSING THE ROTATIONAL MOTION OF THE FAN TO GENERATE ELECTRICITY.
The invention is a new method of electricity generation by tapping motion of the fan, which farther charges a battery bank. The charged battery bank will be used to provide basic lighting to the user and also to run small devices such as radio, mobile battery chargers, etc.
PROBLEM ATTEMPTINGTO SOLVE;
A major part of world today still doesn't have reliable power supply. Energy is getting costlier by the day and power cuts today are becoming a crude reality even for people living in cities across the globe. A huge chunk of population living in the so-called rural areas of the world are reeling in regular power cuts and fossil fuels are being burnt for basic lighting in these areas, which create air pollution, and adding to the already polluted environment. This is the current scenario.
We propose a new method to solve the above-mentioned problems for basic lighting by the proposed new method and device. Our system essentially uses a very small fraction of the energy from the motion of a rotating fan. Our proposed devices made by the new method do not involve any use of fossil fuel and is simple in construction and the materials used are also simple and readily available. Hence the construction and use is very simple and anyone can use it. The invention can be very useful in providing a simple method to provide basic lighting.
PRIOR ART OR ARRANGEMENT:
There is no precedence to this innovation.
ADVANTAGES:
. AU components can be locally produced, easily maintained.
. No specialized materials or skill sets are required.
. Ready to use, when assembled.
. No emissions or consumption of any fossil fuel or dependence on any natural resources like wind, sun, waves etc.
. It can replace lantern which use fossil fuels to provide lighting also during power cuts. It also will lessen the burden on the major power grids supplying majority of power to most of the world today and help its user to save money by reducing electric bills
. Different versions of the devices can be produced for all kinds of fans such as exhaust fans, table fans etc
LIMITATIONS.
The amount of energy generated and stored is directly related to the time of the running of the fan or any similar devices which are used to drive the power generation system.
DESCRIPTION
The following describes the construction of the proposed system.
There are broadly two types of fans used, they are as follows,
Fan type one: AU types of fans in which the fan blades are fixed to the outer rotating case-of the motor, e.g. ceiling fans, Denoted by 'F'.
Fan type two: AU types of fans where the fan blades are fixed on to the rotating central axle of the motor e.g. table fan, Denoted by 'F.T\
Now, the rotational motion of the above mentioned two types of fans is harnessed in two different ways, dividing them into two categories for simplicity,
Category One: The axle of the alternator has to be rotated to generate electricity; this rotational motion of the alternator axle is achieved by harnessing the rotational motion of the fan. The rotating part of the fan is directly coupled to the axle of the alternator with the help of gears or other transmission systems.
The coupling can be done on both sides of the fan, front and back, depending on where the alternator is coupled.
Hence there are two sub types.
A] Coupling in front of the fan.
B] Coupling at the back of the fan.
Both these sub types are applicable to 'Fan type one and 'Fan type two' respectively, hence we have the following types of devices for category one. They are as follows:
1] CATEGORY ONE / FAN TYPE ONE/ COUPLING IN THE FRONT OF THE
FAN.
2J CATEGORY ONE / FAN TYPE ONE/ COUPLING AT THE BACK OF THE
FAN.
3] DESCRIPTION OF CATEGORY ONE / FAN TYPE TWO/ COUPLING IN
THE FRONT OF THE FAN.
4] CATEGORY ONE / FAN TYPE TWO/ COUPLING AT THE BACK OF THE
FAN.
Category Two: The axle of the alternator has to be rotated to generate electricity; this rotational motion of the alternator is achieved by harnessing the wind flow which is generated by the rotation of the fan. A set of small set of blades similar to that of a wind mill are fixed on the axle of the alternator, which rotates when they interact with the wind which is generated by the rotation of the fan. As the wind generated is on both the sides of the fan, the placement of the alternator with a set of blades can be such that it can either interact with the flow of wind before it passes through the fan, or it can be placed in the path of the wind which has passed through the fan. Hence there are two sub types,
A] Placement in the front of the fan.
B] Placement at the back of the fan.
Both these sub types are applicable to 'Fan type one and 'Fan type two' respectively, hence we have the following types of devices for category two. They are as follows:
1] CATEGORY TWO /FAN TYPE ONE/PLACEMENT IN THE FRONT OF
THE FAN.
2] CATEGORY TWO / FAN TYPE ONE/ PLACEMENT AT THE BACK OF
THE FAN.
3] CATEGORY TWO / FAN TYPE TWO/ PLACEMENT IN THE FRONT OF
THE FAN.
4] CATEGORY TWO / FAN TYPE TWO/ PLACEMENT AT THE BACK OF
THE FAN.
In all the above cases we can have a reasonable number of such small alternators which can be paired to generate a greater amount of power to charge the battery bank.
Wind is generated by the rotating fan either in front, back or sides but we have explained in detail only the front and the back, as the wind generated at the sides of the fan is minimal as the plane in which the fan blades rotate is very thin hence essentially the placement of the alternator would fall in the category of front or back of the rotating fan blades, but to complete the entire spectrum of possible positions we also can place the alternator at the sides of the main fan blades. To place the alternator on the sides we would have to design the mounting means accordingly.

COMMON EXPLAINATIQN FOR ; CATEGORY ONE. CATEGORY TWO AND ALL THEIR RESPECTIVE TYPES.
Now, after a certain time the battery bank 'B.B' will be fully charged. A suitable cut off circuit will stop further charging of the battery bank ςB.B' here by preventing damage to the system. Suitable charge indicators will show the amount of power in the battery bank 'B.B' for our reference. During the working of all the types described earlier, the battery bank 'B.B' will be charged and during the evening time or when the lights are needed we can switch on the LED lights 'L' effectively using the stored electricity in the battery banks there by giving us light from the energy generated and stored by our system thus saving on our expenses for basic lighting. As the battery bank 'B.B' will be charged when ever the fan will be running there will be power stored hence even during power cuts or when the fan is not in motion we can use the stored power to give us reliable lighting back up. In an event where the battery bank 'B.B' become fully charged we can connect to the plug point 'P .P' and run suitable appliances like a small radio or charge mobile phone batteries or other batteries, or run any suitable devices. An adjustable clamp 'CL.1' is used but we can also mount the alternator on the rectangular plate 'P' without it. For simplicity we have described the mounting of the gear[ category one] or small set of fan blades which are similar to that of a wind mill [category two] directly on the alternator axle, but we can also use a suitable gearbox as an interface, the gear(category one) or set of fan blades(category two) are mounted on the input axle of the gear box, when rotated, will transmit rotational motion to the output axle of the gear box and further the output of the gearbox is coupled to the alternator axle with suitable transmission means. By the above method we have provided a system which will be a reliable source for basic lighting in places where a fan is being used A capacitor (known as a 'smoothing capacitor') is fixed after the bridge rectifier circuit to reduce the variation in the output voltage and current from the bridge rectifier circuit which charges the battery bank 'B.B'.
FOR CATEGORY TWO;
The alternator has been mounted on the rectangular plate, but it can also be mounted separately by suitable mounting means e.g. on a separate pipe fixed to the ceiling or a side wall etc to get optimum output from the alternator by placing it at the desired position. An e.g. is illustrated in Sheet 9 where the alternator is mounted on a metal plate 'P2' which is independently mounted by its one extremity to the ceiling and on the other extremity the alternator is mounted with the help of suitable adjustable clamp 'CL. V so as to ensure the placement of the alternator with small fan blades to rotate at its optimum power using the wind flow generated by the rotation of the main fan. We have mentioned placement of the alternator at the front or the back of the fan blades only as the wind generated at the sides of the fan is minimal as the plane in which the fan blades rotate is very thin hence essentially the placement of the alternator would fall in the category of front or back of the rotating fan blades, but to complete the entire spectrum of possible positions we also can place the alternator at the sides of the main fan blades by using suitable shape of mounting means. Hence suitable mounting means as illustrated in Sheet 9 can be used other than the types mentioned or the rectangular plate 'P' can be redesigned to achieve the desired placement of the alternator for maximum power generation.
