10th century

The first windmill was seen in Persia. They were used for grinding grain and pumping water to low lying land.Slide3

Windmills of the 12th century

The earliest form of windmills appeared in 12th century Persia.

Located in the center are post mills which would turn to face the windSlide4

Dutch Windmills similar to the windmill pictured were used for milling grains, sawing, and pumping water out of lakes. They were also used for producing boards, paints, oil and paper, and even bread and mustard.

Dutch Wind TurbinesSlide5

Tower Mills

A refined version of the postmill, the tower

mill grinded and stored grain, along with

large sails.Slide6

Fantails

Fantails are small vertical fins, added in 1745 to the back of the windmills to keep them facing oncoming wind.Slide7

Post mills were made of timber based on a single vertical post.

The Earliest European Windmill

They used wooden shafts and ring gears

to achieve a horizontal movement.Slide8

Different Number of Blades

Blades are a key factor to the turbine. Up to 24 blades can be used to power, but four seems to be the best option.Slide9

The Use of Windmills, Water and Grain

Early windmills in both the eastern and western parts of the world were used for the pumping water and the milling of wheat. Even today smaller scale windmills are still used to pump water.Slide10

In this century, people in the United States of America began to use windmills to pump water for the irrigation of farms and the watering of livestock at ranches.

19th Century WindmillsSlide11

U.S. Windmills

Wind engines (also known as American Windmills) are designed to self-regulate and keep their annular sails facing the wind.Slide12

Charles Brush

1888

Brush graduated at the University of Michigan in 1869 and constructed a wind-powered turbine in his backyard in 1888.

It produced 12 kilowatts and lasted for 20 years.Slide13

Poul la Cour

Poul La Cour built the world's first wind tunnel for aerodynamic tests.

In 1891, he invented the Kratostaten, which regulates movement such as wind and the Poul la Cour Key which regulates the power from wind turbine.

1846-1908Slide14

Smith Putnam Design

Palmer Putnam designed a wind turbine in Vermont in 1941 with two steel blades that produced 1.5MW and withstood wind speeds up to 140mph.

The electric control circuit was designed to stabilize the current if the turbine becomes desynchronized from wind. Slide15

200kW Gedser

Wind Turbine

The Gedser wind turbine was built in Denmark, 1957, by Johannes Juul.

It was equipped with an aerodynamic tip that breaks on the rotor blades.

This three-bladed turbine inspired later designs.Slide16

Gedser Wind Turbine & NASA

The Gedser Wind Turbine was used until 1976 then it was refurbished by NASA’s request during the mid-1970’s.Slide17

Wind Turbines and Fossil Fuels during WW2

The use of wind turbines goes hand in hand with the use of fossil fuels. As prices for fuel rose and fell, interest in wind turbines waned and increased accordingly. Slide18

Middle East

The Middle East are innovators in wind turbine designs.

They are one of the first, to build Wind Turbines onto a building. Slide19

Jimmy Carter’s Energy Proposal

President Carter decided to face economic problems by cutting the use of resources and gaining energy through the use of environmentally friendly practices.

Slide20

Wind Turbine Grid Connections

Wind power's wind turbines which is then connected to an inverter that outputs energy to power lines and buildings. Slide21
