Vertical windmills aren't such a new idea. In fact, regardless of that we're accustomed to seeing horizontal axis windmills, the first windmills introduced were the vertical ones. The first functional types were invented in the ninth century, but their design has changed a lot over time in order to get a higher efficiency from them.

Vertical windmills have various advantages. Among them is the low sound that they make. Horizontal windmills usually are extremely noisy, a fact that's proven by their settlements in non-populated or low populated places with not a lot of habitats around. Due to their silent work, vertical windmills are most of the times used by humans for their homes, metropolitan areas or commercial buildings.

Another benefit that vertical windmills have is that they can catch additional wind than horizontal windmills. No matter the direction from which the wind blows, vertical windmills can capture it and convert it into energy. We can not say the same about the horizontal axis form windmills.

A vertical windmill is less difficult to maintain. It is also safer to do it, also. We owe this to the truth that the location of the generator is at the ground level. As it's in such a convenient place and simple to repair, we save a lot more time & energy when we give it maintenance or when we fix it.

Using the vertical windmills' design also brings benefits for the birds. Birds often fly into the horizontal axis windmill. From this point of view the vertical axis type is secured and there are minimum possibilities for birds to fly into its blades.

Vertical windmills can also have an extremely anesthetic look, as they can be adapted to the surrounding area. They don't have a pre-established pattern to pursue when building them. You can find them in plenty of shapes.

The most common vertical windmills are the Savonius & the Darrieus. The Savonius windmill is largely used for pumping the water or for grain grinding. If you look at it from above, you notice that its model is the one of the letter "S". Unlike the Savonius, the Darrieus windmill is used for producing electricity and not for pumping water. Its blades are in model of the letter "C", providing it the aspect of an eggbeater.

We are living in a world where the electrical energy is not only starting to become increasingly more expensive, but we are also becoming more aware that various sources that produce it are affecting the environment. Begin thinking at building your own vertical or even horizontal axis windmill so you can save money and aid save the Earth in the process.
