 * THE STUDY OF WINDMILLS AND WIND TURBINES **

==== The purpose of this study was to find out what position and what shape and size was the best for a windmill. The main parts of a windmill are the low speed shaft, the high speed shaft, the gearbox, the generator, the hub, and the blades. For one of the four experiments performed, the length of the blades was changed and the windmill was put in front of a fan to measure how much voltage was generated. The results, not being expected, were that the 4cm blades generated the most electricity (5.2762 V) and the 10 cm blades generated the least (2.6467 V). What happened is that 4 cm blades generated the most electricity because they were the lightest; being 9.5 g, while the ten cm blades generated the least because they were very heavy (17.1 g). ====
 * ABSTRACT **


 * EXPERIMENTAL IMPROVEMENTS AND FUTURE EXPERIMENTS **

Some things that could have been improved on during are a stronger plastic cup should have been used. Another experimental improvements are the method of keeping the windmill still when measuring. One future experiment that can be done to follow up on these experiments can measure for the most efficient angle of the blade of the windmill. Another experiment can test for the most efficient material of the blades of the windmill.
