How To Make A Windmill - Use Residential Windmills for Electricity
With ever-increasing utility costs, knowing how to make a windmill to accommodate a home's energy needs can be a big benefit. Over the years and decades, engineers and others quickly began to realize that harnessing the wind's potential energy to turn an electrical generator showed great promise. Using residential windmills for electricity is a good idea. The refinement and improvements to these wind-driven power plants continues even today. Some are massive in size, while many more are of small, efficient and personal dimensions.
It is actually not that hard to build windmills, but you should always take care to buy an illustrated set of plans and get the proper materials and tools. Most of the items in a windmill system are either very inexpensive or free, so don't feel any pressure to buy really expensive parts.
Windmills are typically made up of a few parts. They all have at least three blades, with a radius of about four feet. Five blades can be better, though. These blades are hooked up to a direct current (DC) motor, which sits on top of a tower. The height of the tower is dependent upon the strength of the winds in your area, and anywhere from 7 to 15 feet is common. To allow the blades to keep facing the wind, you need to make sure that a fin or rudder sits at the rear of the motor. The rudder will push the motor around on its axis.
After the electricity is created by the DC motor, it travels down to a storage medium. This is usually a collection of batteries, and they will store the power for future use. Always make sure that you select the controller module, so that the batteries will not be overcharged by the DC motor.
Bear in mind, though, that DC power is not readily usable for families, and you need to convert it into AC (alternating current) power. This is why all mills need to use an "inverter" to do the job.
You may like to consider purchasing a small meter which shows the amount of battery power available for use at any given time. This unit will show the power in the batteries and also while its being drawn upon to power the house's electrical needs.
A wind-powered household mill system can be as simple as that. You can either run it separately from the local power grid, or use it to supplement the power you derive from electricity power lines and the like. Also, tying in solar panels to the residential windmill can help you make and store power on windless days. At the very least a good windmill-power storage and monitoring system will lessen the cost of purchasing electricity by a significant amount.
