how to make an working model of wind mills to produce electricity (by students)? Answered


Type "windmill" (one word) into the white search box in the upper right corner of this (or any) I'bles page.  You'll get over a dozen useful results, with many different designs, on the very first page.

Go to the website www.fieldlines.com  they have many many windmills built by knowledgable people.  It is an austrailian website... so some of their english is a bit odd.
