The vertical axis home windmill is the better choice of designs over the horizontal style. The vertical axis design windmill allows the blades to turn around a vertical axle.

Vertical Axis Benefits

This design has many benefits that the horizontal design lacks. For example, it takes less wind to generate electricity and is more effective since it pulls wind from every direction. There’s no need for the wind to change direction and a vertical axis is safer during high wind events. The generator is at the bottom for easy access too.

A vertical axis home windmill can be blended creatively into the yard making it easier for the neighbors to accept. It doesn’t usually destroy birds like the horizontal axis home windmill does.

Horizontal Axis

The horizontal axis design is effective at producing energy. However, the design takes up more room on the property. It is noisier and the blades safety is questioned in high winds. Some zoning boards won’t allow them.

Three Blade Design

The three-blade design is the best type for a home windmill. It is more durable and efficient. This optimizes the balance and gives the windmill an extended life. The blades can be constructed from a long-lasting wood such as cedar, or PVC pipe. A small DC-powered motor is used to generate the power.

A DC treadmill or washing machine motor will work.

You can build a small home windmill of less than 400 watts. It is cheaper and simpler to build. You can use a kit or gather used parts for your design. There are two kinds of kits. One has a building guide for those knowledgeable that can read schematics. This plan type provides a step-by-step process.

Home Wind Turbines

This is a three-blade windmill design that doesn’t store the energy with batteries. The energy they produce can be used while the wind is blowing. They come in horizontal or vertical axis design. This system usually has an output of one to six kilowatts. It doesn’t require rewiring your home.

Safety and Handy Parts

Put off switches on your power route for safety. It is a practical maintenance technique. A charge controller will keep the battery from overcharging. A meter that measures the fullness of the battery lets you know the battery charge at all times.
