Yes, why not make a wind generator today. Make a wind generator at home, use the electricity that is generated by it and you can even sell off any surplus power to the grid and earn some money. No raw materials are needed and no costly maintenance is involved in the process. And what more, it is cheap and easy too. So, go ahead and do it. Here are the basic instructions and all you have to do is to follow them.
First of all, let me tell you what components are needed to make a wind generator at home and then I will give you the idea for locating them. In order to make a wind generator, also called a wind turbine, you would need (a) a small DC motor; (b) Blades to run it when held against wind; (c) a battery or a battery bank to store the electricity generated by the turbine; (d) an electronic control system to save the life of the batteries; (e) a converter-cum-transformer to convert the DC current generated by the turbine to 120V AC for actual use at home; (f) Some electrical wires, terminals and fuses and (g) a tower to hoist the turbine so that it can convert the wind energy into electrical output.
As for the first item, your best hunting ground would be the local hardware store. Look for a small DC motor with high rated rpm. Or you may visit an automobile junk yard to fish out a workable alternator. This will be equally as good. Moreover, you could possibly bargain it at a throw away price since most junk yard stuff are destined to melting pots. However, please make sure that it does not create any untoward noise at a few turns as otherwise it could perform more as a siren than as a turbine when running in high velocity.
Motor selection part over, pay a visit to the hardware store again to get hold of a 6” diameter ABS pipe that is at least 24” long. When sawed lengthwise through the middle line, you get 4 four equal sized blades for the turbine. Now you need a hub to fix the blades and so another trip to the hardware store is necessary. Select a hub that goes freely into the motor’s spindle so that it can rotate freely. Now, bolt three blades onto the hub, maintaining the same slant and then screw the hub tightly to the spindle and your turbine is ready for testing.
Time now is ripe to look for the charge controller and the transformer-cum step up transformer, the ideal site for both the items being an e-bay outlet. Take your time and select the right type. The job of the charge controller is to divert current from the batteries to any dummy load when they are fully charged. Remember, overcharging will shorten battery life. The charge controller can also divert the generated electricity to the grid, whereby you may earn dollars from it. The line coming from the turbine should be connected to the charge controller so that it can function as desired. Since the duty of the converter-cum-step up transformer is to convert the DC output from the generator coming through the batteries to 120V AC, it should be connected at the battery output end.
All connections properly made, you should now hoist the turbine to at least 10 feet high so that it can interact with the availing wind.
Your personal wind power system can save you a lot of money on your electricity bills. Once it has been set up and it is running, the maintenance cost is almost nil, and it is hassle free as well. So go ahead and build your own wind power system and make your own small contribution to clean up the air. This manual will help you learn the essentials such as where in your home it will work best, how to set it up and complete the wiring, where to get the parts from cheaply and what are the safety precautions that are to be followed always.
