You should be living in a windy environment in order to be able to take advantage of wind turbines that generate electricity. Mostly, we think of windy places as being found in the open fields of the country. While that may be true, it is no less a fact that in the most crowded metropolitan areas, strong gusts of wind may blow regularly. If you are living in such a location in the city, nothing should be stopping you from availing of free power.

Everything you need in terms of materials and instructions is easily acquired. After some years, you…and your kids…will be enjoying the fruits of your resourcefulness.

Acquiring your materials for wind turbines won’t be difficult

You can assemble your materials from things you can readily find in a hardware store or special equipments store. The list is extremely short, a mere 5 items. Item number (1) is the generator for your power system. You can select a permanent magnet dc device for this. Item number (2) will be the blade assembly. Item number (3) is the base support of your wind turbine. Item number(4) is the rod that holds the blade assembly, and item number (5) is your storage battery.

Selecting an appropriate motor for the wind turbines

Specifically, your motor should be capable of outputting enough electricity with fewer revolutions per minute. You should remember that, however strong the wind is, it will not be capable of turning your blades at the rate of thousands of revolutions per minute. So look for a dc motor that produces, for instance, 50 volts of electricity with, say, a rotation rate of 350 rpm. In case, if the wind is only able to achieve 150 rpm, you will at least have produced 20 – 25 volts of electricity.

The different types of turbine blades

Two types of turbine blades exist and are characterized by their rotational axis. Horizontal blades resemble airplane propellers. They rotate perpendicular to the rush of the wind

Blades that spin around an upright axis are called vertical blades. The inner side of each blade needs to be curved to maximize the push of the wind.

If you prefer making your own blades to buying them, you can find DIY procedures for that on the internet. For convenience, use fiberglass as your material.

Getting the wind turbines a good stand and support

The size of the stand has to be good for the size of the blades. You will need a stand that can be attached well to the flooring. The material of the supporting tower needs to be rigid while at same time break-resistant.

You could do it faster than I thought up and wrote this article

Any tinkering that needs to be done can be accomplished using basic tools that you have in the house. Kidding aside, I really probably wrote this article faster than you can put up the wind turbines, but that will be sooner than you expected. Then what? Then you should tally all your expenses for putting the generating unit up. Offset that total amount with all the power savings you will be getting monthly (if you use the generator regularly). In one or two years, your disbursements should be recovered. And the next cash-out for maintaining your power system will usually be in 8 or 10 years.
