Natural energy sources 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 small energy can transform the life of a person living in a private house or in a country house, and how to make a wind generator.
There are two types of windmills. Some are similar to weathercocks, others are more complex structures, which include electronic devices. 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 mounted on the axis of the engine. The propeller is very sensitive and reacts even to light winds, and this is necessary when building a windmill. An I-beam made of duralumin is suitable as a supporting beam. Scraps of aluminum with a thickness of 2 mm will take the place of the engine holder, and the keel can be made of duralumin left after installing plastic windows. Material selected in this way is not only very light, but also not susceptible to corrosion. And this is very important. After all, the whole structure is designed to work all year round in any weather. When small energy comes into the house, its owners can not worry about their comfort. In addition, windmills help save money on electricity.
But in order for the design to be durable and in any weather can even respond to light winds, one more technology can be considered. A wind power station occupies the minds of many amateur craftsmen who create their own structures from improvised means. It may sometimes seem to a beginner that this is a rather complicated process. However, in practice, everything is not so scary. Initially, you should take care of choosing a generator. There are options for using DC magnets or a motor from a computer. To make a do-it- yourself wind generator , you need an engine designed for high voltage and low revs, capable of, for example, light a lamp of twelve volts.
When creating blades, some craftsmen use wood. It is much more efficient 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 lengthwise into four parts. Three will be used in the device, and the 4th will remain as a spare. Finished blades need to be processed with emery. Now that the main parts of the wind generator have been prepared, it is necessary to assemble a wind-driven power station from them. In order for small energy to be efficient enough for you, you need to carefully consider all the details and fixtures. The blades and aluminum disc can be secured with bolts. From a piece of plastic pipe, you need to make protection for the engine of the wind turbine. The device itself is best fixed on a board that will act as a stand for the wind generator. A heavy sheet of aluminum attached to the tail of the wind turbine will play the role of a guide. She will be able to rotate the wind turbine following the changing wind. So that the windmill can freely rotate towards the wind, it is better to place it on a tower, which is an iron pipe. It can have a diameter of 2.5 centimeters. The wires coming from the generator must be passed inside the pipe and brought out at the base of the tower. The base of the tower will be a plywood disk with a diameter of 60 cm. To make a shape resembling a horseshoe from pipe fittings, place a tee in the center. He will be able to turn freely. In a wooden disk, you need to drill holes where steel inserts will enter to fix the device on the ground.
Thus, small energy, so skillfully realized with your own hands, will not leave you a disappointed result.
