Small power: a homemade wind generator

Sources of energy of natural origin are very popular both abroad and in Russia. There are enthusiasts who support the idea of clean energy. It can be obtained from solar heat or wind. Let's talk in more detail about how a small energy can transform the life of a person who lives in a private house or at a dacha, and how to make a wind generator.

Windmills are of two kinds. Some are similar to weathercocks, others are more complex structures, in which work electronic devices are included. But first things first. The energy received from the wind can serve to generate electricity for various needs, for example, for lighting or heating water. In order to make a homemade windmill, You can take a stepper motor. An old fan is suitable as a propeller. It must be planted on the axis of the engine. The propeller is very sensitive and reacts even to a slight blow of the wind, and this is necessary when building a windmill. An I-beam from the duralumin is suitable as a supporting crosshead. Cuttings of aluminum with a thickness of 2 mm will take the place of the motor holder, and the keel can be made from the duralumin remaining after the installation of plastic windows. The material selected in this way is not only very light, but also not corroded. And this is very important. After all, the whole design is designed to work all year round in any weather. When a small energy comes into the house, its owners can not worry for their comfort. In addition, windmills help save money on electricity.

But in order to ensure that the structure is durable and in any weather could react even to light wind, you can consider another technology. A wind power plant takes the minds of many amateur craftsmen who create their own designs from improvised means. A beginner sometimes can think that this is a rather complicated process. However, in practice, everything is not so scary. Initially, it is worth taking care of choosing a generator. There are options for using DC or motor magnets from a computer. To make a wind generator with your own hands, You need a engine designed for high voltage and low speed, capable, for example, of lighting a lamp of twelve volts.

When creating blades, some craftsmen use a tree. It is much more effective and easier to use PVC pipes. To get the blades fifty centimeters long, plastic pipes with a diameter of ten centimeters are suitable. The pipe must be cut along into four parts. Three will be used in the device, and the 4th will remain as a spare. Finished blades need to be treated with emery. Now, when the main parts of the wind generator are prepared, it is necessary to build a wind power station from them. In order for small energy to be effective enough for you, you must carefully think over all the details and fastenings. Blades and a disk from aluminum can be fixed by means of bolts. From a piece of plastic pipe, you need to make protection for the windmill engine. The device itself is best fixed on the board, which will act as a support for the wind generator. A heavy aluminum sheet attached to the tail of the windmill will act as a guide. She will be able to turn the windmill after the changing wind. In order for the windmill to turn freely towards the wind, it is better to place it on a tower, in which the iron pipe fits. It can have a diameter of 2.5 centimeters. Wires coming from the generator, you have to pass inside the tube and take it out at the base of the tower. The base of the tower is a disk made of plywood with a diameter of 60 cm. To make a shape resembling a horseshoe from the pipeline fittings, put a tee in the center. He will be free to turn around. In a wooden disk, it is necessary to drill holes, where the steel inserts will enter, to fix the device on the ground.

Thus, a small energy, so skillfully implemented by yourself, will not leave you a disappointed result.
