Hello Kim, Please don't make the mistake of thinking that just because of something belonging to history means that it was not technical in nature. Quite the contrary when you look at many past achievements. The basic principles of windmills are still the same today as in say early American history. The technological improvements have been more towards increasing their efficiency. I have included a link below that will describe the basic principles of windmill operation. And with these basic principles at had, you can build your own.
