How Windmills Work

Understanding how windmills work is not that difficult. The traditional windmills are still available and are the objects that remain popular in people’s minds. But modern ones are now replacing them.

How do Traditional Windmills Function?

These rely on blades that collect the wind which goes over them. The blades look a lot like aircraft wings. The blades’ shape generates a pressure difference on the opposing surfaces. This turns the machine into a central drive shaft.

In traditional models, the shaft is linked to a grinder or stone. The link is made possible by several gears. Other models have power saws. To generate electricity, a generator is linked to a drive shaft. As the blades move, electricity is produced.

Wind Turbines

To learn how windmills work today, there are many things to bear in mind. The first is that they are now called wind turbines. They are also arranged in large clusters known as wind farms. Their placements are designed to maximize natural wind corridors.

Today turbines generate 40% of the electricity on the planet. The majority are powered by steam. The steam heat is courtesy of nuclear fission or burned fossil fuels.

Turbines are gaining popularity due to zero emissions. Unlike other power generators, the source is renewable. All modern turbines are linked to generators which make electrical potentials in the transmission wires move.

Turbine Powered Generators

These rely on motion to create electricity. In this regard, they are the direct opposite of motors. Some wind turbines can produce up to 100 kW of energy. Combined with machines in a windmill farm, the energy will produce greater amounts of energy. The biggest wind farm can power over 200,000 homes annually. This wind farm can be found in Texas.

Drawbacks

The biggest is the cost of production and maintenance. Relying on the wind also has problems. However, the limitations are being overcome by technology. Their efficiency is also being enhanced.

Other Information

There are basically two kinds of windmills; the vertical axis and horizontal axis turbines. The former is more common. The vertical axis types have blades resembling an egg beater. The horizontal axis have blades shaped like those on airplanes.

When studying how windmills work, keep in mind that electricity is created within. Even though there are variants, they are linked to the blades. As long as a breeze is present, electricity will be generated. In essence, that is how all these turbines function.
