wind rurbine history

Wind energy conversion is a spellbinding field to study, if

only because its past has been so checkered and its exact future is so vague.

But unlike many of these other industries, wind

energy has been around for thousands of years and it's a technology that has been

reinvented many times.

Have you ever wondered…

WHERE and WHENdid Wind Energy start?

LET’S GO ON A QUICK JOURNEY

HISTORYOF

WIND POWER

500 B.C.

500 B.C.

The development of sail boats led directly to the development of the first recorded

wind powered device in Persia (the Middle

East)…

Sails were used to drive a mill stone for the grinding of grain. These were seen first in Persia,

500 BC.

500 B.C.

Some versions were also used to pump water for

drinking water and for simple

irrigation of agricultural land.

1300 - 1850 A.D.

This type of windmill design became familiar

in Europe between 1300 and 1850 AD.

1300 – 1850 A.D.

The windmill design is much more like the

traditional windmills we see

even today.

1300 – 1850 A.D.

It was designed particularly for the large scale

milling of grain.

1300 – 1850 A.D.

19th Century

In the USA wind powered devices

like the one shown in the illustration

were developed to pump water.

19th Century

These were especially functional

in bone-dry areas where deep wells were essential to

find drinking water

19th Century

In the 1800s, the Halladay windmill

was very trendy with thousands made.

19th Century

This basic design was reliable and was

used even up to the 1940s.

19th Century

A large version of this design had

rotors (propellers) of 18 meters in length.

First Use of Wind for Large-Scale

Generation of Electricity

20th Century (USA)

With the development of electrical power,

scientists and technologists developed

ways of producing electricity through the use of wind generators

(also known as turbines).

20th Century (USA)

In the 1930s one of the largest experimental machines, called the

Palmer-Putman machine was first used.

20th Century (USA)

This was capable of producing 1.25

megawatts of electricity.

20th Century (USA)

However, due to the materials available at the time, its effectiveness was reduced to a great extent

and made the machine hard to maintain.

20th Century (USA)

It had 50 meter rotors which were large compared to

other designs.

Due mainly to the fast rise in oil prices throughout the

late 1970s and 1980s,

AND

the fact that using fossil fuels to produce electricity

causes pollution,

which can damage the environment and cause

global warming,

ACCELERATED!!!

THE RISE OF MODERN

WIND TURBINES

Modern wind turbine generators are robust, sophisticated high-tech machines designed to convert the power of the wind into electricity.

They generally consist of a rotor with three blades.

A nacelle, which typically contains a gear box, generator,

brake, yaw motor, and yaw drive.

And an anemometer for measuring

wind speed.

This is how it looks like …
