A windmill is a renewable energy source that converts the wind’s force into mechanical energy, which can in turn be transformed to electrical energy. If you need to design a suitable windmill for your home, then a number of considerations should be made before you start to build your windmill.
The number one consideration is unquestionably the wind speed. Once you have determined the average wind speed in your location, choosing the right design is simple.
If the wind speed averages around 8 mph in your location, then you can benefit from a vertical windmill design. Vertical blades turn easier even on the presence of the slightest wind. You can also add a gear box to speed up the rotation at the generator if required.
If the wind speeds average around 12 mph in your area, or rather a little faster than that, then a horizontal windmill design is highly recommended. The three blades horizontally facing the wind will enable you to catch more wind energy which will in effect turn the generator shaft faster, usually at speeds of 600 rpm.
Location is your next important consideration for when considering using this renewable energy source. This element is crucial, particularly if during the first step you have decided that a horizontal blade design was most suitable. As the blades face the wind, and often with a rotational perimeter of six feet or wider, the entire turbine should be able to get up into the wind. If trees, buildings or other structures block the wind, it would be better to choose a vertical blade design.
A vertical blade design requires only a little wind to get it turning, and will be the best option if some issues are preventing your turbine from turning properly. The disadvantage of vertical blades is that they don’t turn as fast as they should and thus won’t be able to generate enough renewable energy without the help of a gearbox to speed up the rotation at the generator.
