Windmill or Wind Turbine Theory

submitted by enginedeer007 from self.AskSaidIt

I will say this first is that they are on purpose designed to be UNRELIABLE... one of the HUGE clues is how blade fans work. Just cutting to the chase those Wind Turbine blades are design to spin at thousand RPM not to "catch the wind breeze'... I believe an actual fan blade engineer knows this... chine in sir? We will figure this out eventually because collective minds always win!

In effect, wind turbines are design to fail on purpose. = "theory".

You can just look at all fan blade shapes for yourself.... to your living room ceiling fan to an industrial/commercial one. To even toys in my theory collection it all points out that the Wind Turbines have a blade FLAW design on PURPOSE. In my opinion if all homes had a wind turbine we would not need electricity to buy.....of course we also need batteries but my point here is to make that the wind turbines are flawed...

Before you say anything negative tell me why a helicopter can fly with thin fan blades?

A fan blade is not necessarily an airfoil. Propeller and rotor blades are designed for lift. They have a distinct shape to their profile.

Wind turbines generally work in places with maintained wind. If you live in a place with intermittent wind, there are wind turbines with a cylindrical shape that work better for that application.

WHat is an "airfoil"?

One side of the blade or wing on an aircraft is flat and one side is curved. This forces the air across the curved side to speed up so that both sides reach the trailing edge at the same time (curved side has farther to travel to get there). This causes lower pressure and "pulls" the wing, propeller, rotor in the direction of the lower pressure (think vacuum). You can look up Bernoulli's Principle for more on how this works.
