If you learn the ins and outs of how to make a home windmill, you will understand at the end of the process how it all works, whether you like it or not! Although things may seem complicated at first, they are really not that bad. It just takes some time and focus to make it work. The cool thing is that windmills have been around for centuries. They started out working as paddle wheels in the water either on a steamboat or turning a power turbine in a stream. Below are the major parts of a home windmill and an explanation of each: 1. Blades - this is probably the most important part of the whole design because the blades drive the system. Most are aerodynamically fashioned to most efficiently drive the turbine with the least amount of available air movement. Blades can cost a lot depending on if they last a short time or a long time. Metal blades are popular in harsh weather environments. 2. Generator - where the rubber meets the road. This part of the system actually turns the mechanical energy of the turning shaft rod into electrical energy that can be used in a battery or in your home. 3. Shaft - the shaft is the drive mechanism. It connects the blades with the generator. Of course, it is made out of high gauge steel so it isn't likely to wear out. 4. Grid tie inverter - if you are going to sell power back to the grid, you need this to convert to AC power. If you want to export power back to your electric grid, that is something that can be done even with a small turbine. It is wise to and in most cases necessary to have a utility trained technician to do the final hook up for you. That will allow you though, to sell the power you make in excess of your home requirements back to the utility. This can seriously offset the big bucks you are paying for power now at home. I am going to tell it to you straight - if you launch into building your own turbine, it will take some time. Time you would rather be doing something else in many cases. You just have to have the mindset that you are installing a system that will continue to provide you a return for years and years after it is paid for. Take the time to learn these basic parts and what they do. If you eventually learn how to make a home windmill then you will be miles ahead. Buy a set of plans and learn all you can about how the windmill works best. This is a cheap education that will payoff for years to come.
