and freedom from power outages and the high cost of electricity will be yours. Another important benefit is that

A wind generator is loosely defined as any device that can
extract some of the energy from the wind and convert it into usable electricity. The terms windmill and wind
turbine are often used interchangeably to describe similar devices.
The generator is comprised of 5 main
- The Blades
- The Generator
- The Tower
- The Battery Storage Bank
- The Electrical System
The Wind Generator Blades
The design of the blades are the single most important
factor for determining how efficient a windmill generates electricity. The horizontal spinning,
airplane-propeller style blades can be one of the most efficient designs in consistently strong winds. Their
count, length and pitch are the factors that have the biggest impact.
When the wind tends to be lighter, inconsistent or
constantly changing an upright spinning blade design, often referred to as a vertical axis wind generator is
sometimes best. This type requires less energy to begin spinning and doesn't have to be reoriented when the wind
shifts. The vertical style is usually much quieter than its horizontal cousin which makes it more neighbor
Another version of the vertical axis windmill uses a
helical style of blade. This is ideally suited for rooftops where the wind becomes vertical as a result of
impact with a building.
This is the part of the wind turbine system that converts
the rotation of the blades into electricity. Direct current electrical motors are often used for this purpose.
When rotated backwards they change from electricity consumers to electricity producers.
For a wind turbine to work well, it needs to be exposed to
as much consistent wind as possible. The height of this tower is primarily determined by how much open space you
have, local community zoning laws, and how high you need to get the turbine to avoid
Towers typically range from 8 and 75 feet tall. The
shorter heights are more appropriate for areas with a high natural elevation such as a hill or a rooftop. Some
towers are designed with a hinge so that the tower can be lowered to ground level for convenient maintenance of
the blades and generator.
The Battery Bank
This purpose of the battery bank is to provide the freedom
to use the wind generated electricity whenever you want to instead of only at the moment it is produced. Deep
cycle batteries are often connected in combination patterns of both series and parallel depending on the voltage
you are working with.
A small electrical device called a charge controller is
usually connected between the batteries and the wind generator to prevent damage from
The Electrical System
Power stored in the batteries is in the form of direct
current. This usually is converted to alternating current of the correct voltage and amperage in order to be
able to run common household appliances. This is accomplished with a device called an inverter that is connected
between the output of the battery bank and the house.
The easiest connection with the house consists on not
connecting with the household grid system. Instead the wires from the inverter enter the house and are connected
to one or more new electrical outlets that are not integrated with the house wiring. With this method only
certain lower energy appliances like televisions, computers, lights or dvd players are plugged into these
outlets. The big energy consumers like the air conditioner, heater and stove would be left to the power
The connection with the house can alternately be
integrated into the household wiring at the main circuit box with help of a licensed electrician. This method
reduces the amount of outside electricity that is needed from the local power company. In some communities, any
excess electricity is sent out on the local power grid for other houses to use. Some utility companies will
actually pay you for this.
The Need For Plans
Because of the many variables it can be complicated to
design one yourself. It is wise, at least on the first project, to purchase plans where the specific dimensions
have already been worked out by someone else. Some of the best plans even show you where to scrounge low cost or
even free parts and materials. It is possible to learn how to make a wind generator in less than a week for just
a few hundred bucks.
