This project is about Making of Energy on home with some motors.

What is Wind Energy?
Wind energy is energy from moving air, caused by temperature (and therefore pressure) differences in the atmosphere. Irradiance from the sun heats up the air, forcing the air to rise. Conversely, where temperatures fall, a low pressure zone develops. Winds (i.e. air flows) balance out the differences. Hence, wind energy is solar energy converted into kinetic energy of moving air.

Wind Energy Converters (WECs) - wind turbines - capture the air flow by converting it into a rotational movement, which subsequently drives a conventional generator for electricity

Step 1: How Much Power Is in Wind Energy?

When air mass is flowing through an area A with speed v, the power of that air movement at time t is given by:

Pic: 1 or

P(t)=1/2ρAv(t)3

where ρ is the density of air, which is around 1.22kg/m³. The energy (kWh) is the product of power and time

Pic: 2 or

E=PT=½ρAΔΣ(i=1...N)Vi3

Step 2: How Turbine Motor Works

Wind turbines operate on a simple principle. These pictures shows how energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. Wind turbines are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more above ground, they can take advantage of faster and less turbulent wind. Wind turbines can be used to produce electricity for a single home or building, or they can be connected to an electricity grid (shown here) for more widespread electricity distribution.

Step 3: Items Required

In this project we need some costly product:-

1. 8 motors(Simple toy motors)

2. 1 LM7805 IC

3. Some wires

4. A stand for 8 motors.

5.Female USB Hub

Let's start.....

Step 4: Theory

A motor can generate energy when you put a blade on it and put both thing in front of wind blow.

There are three cases:-

1. when we connect +ve terminal of battery to +ve terminal of motor and -ve terminal of motor to -ve terminal of battery then motor is in working process. And blade moves in clock wise direction.

2. when we connect +ve terminal of battery to +ve terminal of motor and -ve terminal of motor to -ve terminal of battery then also motor is in working process. And in this case blade moves in anti-clock wise direction.

3. When we put the motor in front of wind blow with a blade then -ve terminal of moter give +ve value and +ve terminal give -ve value. And in this case blade moves in anti-clock wise direction.

Step 5: Making Procedure and Small Demo!

Sorry Guys i'm giving small demo because of lack of motors and blade. I tried so hard but in the end i found 3 motors only because in my area no one keeps this type of motors.

Now, As you see in picture 1st picture it gives me 937 millivolt if we connect 8 numbers of motor in series then it will five 937*8=7496 milivolt i.e., 7.5 Volt (approx). By adding a LM7805 IC a constant voltage will be provided that is 5 volt. then you can use it any was charge your mobile, battery, Glow your LED Etc.....

Thanks for reading so much.

Make it and enjoy. And one thing if you made it then send me a demo Please........

<p>I am the instructables Grinch on people who claim to generate <br>energy ( or power ) and then just sight the voltage produced. This <br>is not valid ( <a href="https://en.wikipedia.org/wiki/Electric_power" rel="nofollow" style="">https://en.wikipedia.org/wiki/Electric_power</a> <br>). You need to add a resistor to the circuit and then measure either <br>both the voltage and current and then P = V*I or if the value of the <br>resistor is accurately known you can use ( P = V^2 ) /R. Your answer <br>will strongly depend on the value of R, and there is an optimal <br>value. There is noting wrong with your basic idea, but adding this <br>sort of data would be a major improvement ( in my opinion ).</p>
<p>Sir, As you can see in procedure picture 2 &amp; 3 a LED is glowing this LED is not glowing continuously because when i blow with my mouth wind flow is not constant it's vary up and down if we use high blowing machines like blower or vacuum cleaner that will give constant volt that's the problem. In that case it might be possible the voltage will increase and LED will burnt that's why we have to add a resistor to the circuit and then glow the LED. When the 8 motors then they will give 7496 milivolt i.e., 7.5 Volt that is a high voltage for that we use a Constant Voltage Regulator in the circuit to give constant voltage...... Now this is known thing that a LED cant take that much volt so use resistor to the circuit....</p><p>If i made some mistake then tell me... I appreciate that...</p><p>Thanks for comment </p>
<p>The point is you need to measure the current at the same time you measure the voltage. Having or borrowing a second meter is useful.</p>
<p>I know what you are telling my friend. I already checked it and I'm giving some pic as a proof that it's working...</p>
<p>Yes it it &quot;working&quot; but you have no real numerical value for the power just the idea that there is &quot;some&quot; </p><p>As Lord Kelvin said:</p><p>&ldquo;When you can measure what you are speaking about, and express it in numbers, you know something about it, when you cannot express it in numbers, your knowledge is of a meager and unsatisfactory kind; it may be the beginning of knowledge, but you have scarely, in your thoughts advanced to the stage of science.&rdquo;</p>
<p>I think now your are satisfied we my project...If not then tell me</p>
<p>and one thing more i attached both voltmeter and ammeter at the same time. But the current power is very low we can say negligible that's why i didn't mention it here. and i think that for no use...</p>
<p>http://energy.gov/eere/wind/how-does-wind-turbine-work</p>
<p>We know about it but we never apply this in home... I'll try this time...</p>
<p>Great job. nice innovation.</p>
My 12v dc motor won't light even a single led
My 12v dc motor won't light eveb a single led
Don't you have to use a DC motor to make electricity rather than an AC motor
<p>DC motor are producing electricity.. Than why to use AC motor!!!</p>
<p>between ac and dc motor which one is use for wind energy</p>
