What Is A Vertical Axis Wind Turbine?

Thinking of adding a wind power system to your home to lower your energy costs? Worried about putting up a large tower with guy wires spreading across your property to stabilize it, or are you on a smaller site where that type of tower isn't feasible? Let's look at a couple of options available that will let you take advantage of the wind no matter where you are living.

Vertical Axis Wind Turbines (VAWT) are windmills that have helical shaped blades mounted vertically to the generator. They are specifically designed to address the unique problems associated with producing electricity in urban or suburban areas where often a horizontal wind becomes vertical when it encounters the face of a building. The helical shaped blades of the VAWT utilize vertical or horizontal wind bursts coming from any direction (omni-directional). This makes it more useful in these areas than the more prevalent roof mounted Horizontal Axis Wind Turbine (HAWT) available in most home wind power systems.

The HAWT systems work well in more open settings, a rural area without trees or surrounding buildings that break up the flow of wind coming to the blades. There are a number of smaller designs built specifically for home use, a lot of these are DIY kits that allow you to set up the system yourself, saving on the cost of professional installation.

Studies have shown vertical systems generate energy at a lower wind threshold than a comparable horizontal turbine. They also will produce power past the point that the increasing wind causes the blades of a horizontal turbine to feather to prevent damage from over powering the system. The larger, helical designed, slower rotating blades are also more visible to birds than the thinner propeller style of wind vanes used in a horizontal axis system. The Savonos style of vertical axis wind turbines can offer magnetic levitation instead of traditional ball bearings in the generator to blade interface, drastically reducing friction. With less friction, less energy is needed to turn the blades allowing the system to operate with lower winds.

Vertical versus horizontal. Which system to use? Each has their own pluses and minuses, and no one type will be perfect in all wind conditions for all sites.

Learn about the alternatives before purchasing. Start with the Internet to learn about the options, including information on siting, required permits and net metering available to add your system to the power grid. Knowledge is power. Your research will help you on your journey towards energy self-suffiency and improving your environment.

Solar Power Water Heater

Did you know that a solar powered water heater installed in your home will reduce you your electric bill. The installation of the system is very simple, You can easily get the parts and make the solar heater in your home for less than $100.

I came across some information that will really assist you in building your own solar hot water system and how this benefits the go green environment our planet really needs. Solar powered water heaters has been given productive results in hot and cold climates.The design and construction of a solar water heater is very simple and only needs few days to complete it.

The latest guide from Diy Hot Water System has been released that will help you achieve the goal mentioned above. This is how the system works, the sun produces a vast amount of energy into the atmosphere. This energy is converted into electricity which in return used to heat up your water heater and will help save you hundreds of dollars on your power bill.

Most of the materials are available at your local hardware store and you can complete the entire unit for less than a hundred bucks. A beginner can easily understand the instructions given in the guide for installing this system.

Here are a few more reasons why should consider installing one for your home.

  • You can reduce your power bill by up to a third.
  • This is a practical way to help our environment.
  • You can use the system anywhere in the world.
  • It is a great project you will have fun building it

With the Diy Hot Water manual you are going to learn everything you need to know about installing a solar hot water system in your home. Download now!
