Vertical Wind Turbine Cheap Solutions

A Vertical Wind Turbine can be the best investment those days, not only for producing free electricity and saving lots of money but also for helping the environment. Yet Wind Turbines are quite expensive and not many of us are so fortunate and able to make such a wise investment. Should this stop you from trying to use a clean, sustainable form of energy like wind energy?
I think not. In my videos you can discover some cheap solutions to purchase a Vertical Wind Turbine and tapping into the power of new free electricity.

Micro Wind Turbines

Feasible, reliable and cost-effective Micro Wind Turbines are quickly becoming the next best investment for your home. Coming in all sizes and shapes, some micro wind turbines are more effective than others. Still keeping an eye on affordability, i've put together an informative list of the best Micro Wind Turbines here.

DIY Wind Turbines

Here you have two choices:

• a DIY Wind Turbine Kit where you get all the wind turbine parts and instructions; all you have to do is to build it in your chosen location and at your own pace.
• a DIY Wind Turbine Instructional Guide where you learn everything from where to get the component parts at very low prices up to how to assemble and install your wind turbine without much trouble.
  

Second Hand Wind Turbines

Like with every other product worth purchasing, huge savings can be made in the second hand market. Just Google "second hand wind turbine" and choose wisely. A word of caution: perform a through research in the field before making the final the decision and learn all the weaknesses of the chosen product.

Wind Turbine Components

Wind turbines come in many sizes and configurations. But no matter if they are big or small, horizontal-axis or vertical-axis, every wind turbine function on the same principle: extracts energy from wind, transfers this harvested energy into a spinning shaft which turns an alternator or generator to produce electricity.

So the basic components of a wind turbine are:

• Blades or rotor, which converts the energy in the wind to rotational shaft energy.
• Nacelle that houses a drive train, usually including a gearbox, a generator , support bearings and some other parts.
• Tower, that supports the rotor and the drive train.
• Ground-mounted electrical equipments, including electrical cables, controls and interconnection equipment.

Most traditional wind turbines have three large steel blades, but the rules are not set in stone. New blade designs and materials are constantly experimented and sometimes proven more efficient than the traditional ones.

The power available to harvest from the wind largely depends on both the wind speed and the area that is swept by the turbine blades.

• for a double wind speed the energy available increases by a factor of 8.
• for a double rotor diameter the energy available increases by a factor of 4.

However is not possible to harvest all the energy and turn it into electricity. By the Betz Limit formula there is a maximum of 59.26% that can be extracted from the available power. Also no alternator or generator is 100% efficient in converting the energy into electricity, and factors like friction, magnetic drag and electrical resistance losses will further reduce the wind turbine efficiency.

This means that no small wind turbines are 100% efficient even when running at maximum speed.

This is the reason why the rotor diameter and the generator model are the most important factors when choosing a wind turbine model. Hopefully realistic expectations will help you make the right choice and avoid unsubstantiated claims and products.
