they both provide energy through wind power. vertical wind turbines have more blades and can catch more wind,they also require less space so are more practical if you have a smaller area of land.
They are suitable for balconies or patios, and unlike horizontal wind turbines a vertical axis turbine can have the gearbox placed at the base of the structure.Vertical wind turbines also dont' need to face in the direction of the wind..
One disadvantage though is that you can't place a vertical wind turbine on the side of a steep hill. It has to be placed somewhere fairly flat. This shouldn't be a problem though if you are sitting it on a patio or balcony.
Vertical axis wind turbines don't need to be mounted on tall towers and this is another advantage if there are issues on your land with height restriction.
However being closer to the ground than a horizontal wind turbine there will be less wind available which could make it up to 50% less efficient. It will still produce energy from the wind though, and can certainly help reduce your electricity bills. The fact that it has more blades does help to catch lower wind speeds so not all is lost
There are different types of vertical axis wind turbines and the latest one has a rotation sail. This makes it look like the sails on a ship, and as the wind changes these sails can expand or contract. It has three sails and the speed is managed through a magnetic counter that can make them expand or contract.
The frame is very strong and durable and will stand up to very strong winds and storms. The sails though can sometimes tear, but are replaceable.
The aerodynamic wind turbine has an airfoil base that's designed to capture the kinetic energy flowing from an artificial current to the center. It can utilise most of the air mass that passes through by redirecting it over the top of the turbine. It can respond to wind, rivers, oceans and other free flowing water systems.
Darrieus wind turbines are efficient but due to their size and shape they can produce stress on the tower which may cause it to wear out quicker. It has three blades that perform well in high winds and they are supported by external structures that are connected from the ground up.
The Giromill has three vertical blades. It's self starting so doesn't need much maintenance. It has a low blade speed but performs well utilising the power of the wind very effectively.
Savonius wind turbines have two scoops that are used to generate wind power, although some have three scoops that make it self starting. They look like long helicopter blades that are bent in a direction. They are designed for high performance and work well in low wind speeds. Savonius wind turbines have to face into the wind and aren't suitable for residential property as they have a much larger turbine than other types of vertical wind turbine.
Windstar turbines have straight aluminium blades that are attached on each end of the rotating shaft. They have more than one rotor as well as their own dual braking system that has pneumatic disc brakes. Windstar Turbines are designed for very strong winds.
Horizontal wind turbines are the most efficient but usually require a far greater area of land and need to face into the wind. This type of wind turbine is often seen in large fields or off shore. They are often used commercially to power homes in the immediate area.
Installing a horizontal wind turbine in your back yard is usually not very practical. The swishing noise of the giant blades and it's large structure wouldn't make you very popular with the neighbours! The blades spin at a faster rate than a vertical turbine providing a greater danger to birds and anything else that gets in it's path.
Discover how you can create your own wind power system using materials bought from your local diy store. Build your own wind turbine for under $200 with very little diy experience by following an easy to understand step by step guide.
Generating your own power using a wind turbine is environmentally friendly and can save you $1000s in electricity bills.
Once you have done your research into deciding if it's practical to install a wind turbine on your land then you have to decide which type of turbine will be most suitable for your needs.
There are two types of wind turbine, vertical and horizontal and although they have their own advantages and disadvantages
