Why does windmill have only 3 blades?
Windmills only have 3 blades because if there were 4 or 2 it would not spin!!! I HATE MATH!!!!! Windmills do have more blades sometimes, I've seen plenty.
Do windmills blow?
No. Windmills have their blades angled in such a way as to catch moving air or wind. When the wind hits the blades it pushes them and they spin, which then gets other gears of the windmill turning, which then generate energy for whatever it is they need that energy to do. So the windmills themselves do not make wind or "blow".
How is wind energy collected from nature?
Wind energy is collected by the use of turbines or windmills. The blades on these windmills are designed like airplane wings, and they produce 'lift' that turns the blades. The blades are connected to electric alternators, generating electrical energy for use in home and industry.
Can you find windmills in America?
Yes, you look for the giant towers with blades that are spinning.
How do windmills catch the wind?
The blades are shaped like air plane propellers and use the airs force to push on the shape of the blades.
How many number of blades are there on a wind turbine or windmill?
there is three or four
Why are wind turbines three bladed when more blades should catch more wind?
the reason there is only three blades is because four blades would add weight and wind resistance, in some countries they use two or four bladed turbines though. \
What is the difference between fans with 3 and 4 blades?
nothing a fan with three blades is just weaker and smaller than a fan with four blades! <3
How do wind mill?
Windmills use blades to gather wind that flows over it. Just like an airplane uses wings for lift, windmills use their blades for lift as well - in this case to turn the windmill. Windmills are pretty simple structures; their blades are connected to a drive shaft that is connected to an electric generator. As the blades turn, this turns the drive shaft and creates electricity. Electricity is sent through wires and collected.There are several different types of windmills, categorized by the direction in which their blades rotate. Two different types of windmills, most commonly called turbines when producing energy, are the horizontal axis turbines and the vertical axis turbines. Horizontal turbines are by far the most popular type of turbine and are the traditional type of windmill with blades that are similar to an airplane's propeller. These are the windmills we often see pictures of - the Holland variety. On the other hand, vertical axis windmills have blades that resemble an egg beater. They are far less popular than horizontal windmills only making up a very small overall percentage.In addition, wind mills can be used to harness energy without producing electricity. An example is the type of windmill that takes the mechanical motion induced by the blades to turn millstones that grind corn and other grains, hence the term "windmill". Other examples of non-electrical windmills include those that pump water. (These have been around for a long time.)

Why do fans have 3 wings?
An electrical fan can have two, three or four blades. The main thing is that the number of blades must be balanced to avoid juddering.
How many windmills are destroyed during the story?
Three windmills are destroyed during the story.
