Helix wind turbine, vertical as well as other types of vertical axis wind turbine (Foote) have become very popular now, but not be right for your home page and here is why ...
First, a couple of definitions so that we can agree that we are talking about:
Rotation of wind turbine rotor shaft vertical perpendicular to the ground. Rotation of wind turbine rotor shaft horizontal parallel to the ground.
Based verticals have nicknamed "agbitirs" because of the way they look and horizontal turbines resemble classic windmill.
Similar to the horizontal and vertical wind turbines in the following ways:
1. the same basic components: a blade and gearbox controller generator.
2. can be quite loud.
This is where the similarities end.
Here are the pros and cons of vertical wind turbine for the home, where you can decide for yourself:
Vertical systems advantages:
1. torbolint flow based verticals handle better than horizontal turbines.
2-based verticals is usually closer to Earth, so they are easier and cheaper to access when problems arise.
3. they're indifferent to wind-no "find" wind with tail
4. safer bats and birds.
Vertical windmills disadvantages:
1. cost much more.
2-based verticals running torque too high, so it's hard to get blades turning in low wind conditions.
3. Stresses the need to put them in this kind of winds it tends to work in much of the horizontal axis.
4. efficiency ratings less than vertical based verticals.
Discussion of deeper issues:
For small turbines for domestic use, not simply vertical axis wind turbines more efficient at making power as the horizontal axis systems.
There are 3 key factors contributing to the inefficiency of vertical mill:
1. non-aerodynamic supply in transfer "savonios"-like rotors.
2. a stress damage to the shaft and bearings due to the higher torque.
3. vertical axis windmills tend to load closer to the ground or on surfaces where the air is more unstable. Do not reside in the higher elevations, wind power provides a consistent rich is powered.
More about first-there are 2 main categories for vertical system design:
1. savonios rotors are similar visually 55 gallon drum in some respects, reduce to half. Savonios rotor systems are very effective (5-10% efficiency) because they have any help turning of aerodynamic surfaces. Most new vertical systems savonios type rotors.
2. Darius rotors, which look like agbitir. To deal with these systems efficiently because the horizontal axis systems designed blades with aerodynamic (an elevator). (Horizontal systems able to theoretically up to 95% efficiency). Wind turbine vertical Helix type, and can prove efficiency within 30 per cent.
Concerning the second factor, which negatively affected efficiency because of pressures at the vertical systems and the resulting wear. How vertical wind turbines are marketed to consumers that they can be mounted on the roof or very low to the ground, thus eliminating additional expenditure for the tower. Rising low negative impact on efficiency in two ways:
1. wind closer to ground unit leads troubled stop/start, and change frequently. Lead mechanical wear on the bearings at the top and bottom of the rotor shaft, reducing the useful life of the turbine.
2. manufacturers of way compensate for wear and tear up beef in turbine building materials. This of course makes the turbines cost more.
Finally the third factor: wind near the ground clutter and troubled because of interference from buildings and trees. Turbulent environment rather than almost anywhere in the turbine efficiency higher up above the tree line. This is where most all wind-top, where there are no barriers to slow it down or turn around objects and change direction.
If the vertical axis wind turbine efficiency in electricity production, why they became popular then?
I think there are 2 reasons:
1. it is more aesthetically appealing horizontal axis devices. Recent studies have shown in Europe they are Sandman even somewhat as "hesitation". Be calm like watching the waves on the beach on the human psyche. It does not shift and change trends such as vertical and tail. They revolve. Therefore, we must look to do their job.
2. the myth that they can work soon on the ground. We believe in theory, if we could deploy an army of such devices in all parts of the roofs, can solve the energy crisis.
They are simple combination, and get running and it's not usually portable control tower. That makes them attractive for those who want to participate in wind and renewable energy, but don't want the hassle of a major project to study the feasibility for improving wind, flowing mainly Tower wind, and maintenance costs associated with household energy systems.
Abstract snail wind turbines are vertical and the vertical axis wind systems for homes just aren't ready to go after.
If your goal was to create many electricity for your home price will allow faster payback in life, useful mill based verticals out. Is a good choice only so far to buy or build a horizontal axis tried and true.
However, if your goal started quickly and start making some electricity from wind and you won't obsess over numbers, vertical helix and other vertical axis turbines will make you feel good you participate in creating renewable energy and take some action.
Can hope only to vertical wind turbines manufacturers continue to refine their snail and overcome these drawbacks. He promised "wind turbine per plane" If that happens, it's getting cheaper, may be a reality some day.
