For optimum efficiency you’ll want several cascades of these, all of which converting the mechanical rotation in to different forms of energy.
#1 Stored Water Pressure Turbine: Mechanical energy can pump a working fluid to store energy as pressure.
->Energy stored as pressure can be accessed by converting it to mechanical rotation in a turbine.
–>Pumps can be replaced with CD-ROM tesla turbines, which can also be used as the generator turbines.
Proposed Conventions used for Drag Type Turbines
It is very difficult and time consuming to describe how the wind (or water ) interact with a drag type turbine. In some phase of rotation sail moves at the same direction with the wind, while in the other it moves against it. The sail also has two faces. While the wind acts on one face at one half of the rotation, it acts on the other face in the other direction. To simplify description of the wind and turbine interaction we come up with the following conventions in this site. Please note that, older pages are not written with this convention in …
The newly released Delta Series, which includes the Delta I and Delta II, are truly revolutionary in the wind industry. Since the wind has blown, and man has tried to capture it for energy, it has been widely known that the fixed 3-blade VAWT has great potential for very powerful energy production…unfortunately, it has also been widely known to have two major design flaws. It cannot self start in low wind speeds, nor can it self regulate in mid to high wind speeds; thus, causing greatly reduced efficiency (due to starting and stopping …
There is more reason than ever for everyone to exercise more caution regarding the world around us. Not only are you going to save the environment, you will also save money.
Maybe you have never considered the possibility of building your very own version of a DIY Vertical Wind Generator. These structures are similar to other wind generators but the blades are vertical instead of horizontal.
You can easily build your DIY vertical wind turbine by using the plans that are available to help you build wind generators. You just have to make sure that blades are vertical when you attach them. …
From Wind Energy wiki
Horizontal-axis wind turbines (HAWT) have the main rotor shaft and electrical generator at the top of a tower, and may be pointed into or out of the wind. Small turbines are pointed by a simple wind vane, while large turbines generally use a wind sensor coupled with a servo motor. Most have a gearbox, which turns the slow rotation of the blades into a quicker rotation that is more suitable to drive an electrical generator.
Since a tower produces turbulence behind it, the turbine is usually pointed upwind of the tower. Turbine blades are made stiff to prevent …

A wind turbine is also referred to as a wind generator or windmill. Though the terms are used interchangeably, there is a minor difference. The wind turbine is the device that uses the wind power to create mechanical energy. This mechanical power is then used as is or switched into electrical energy. A windmill applies the mechanical power as is for taking out water or for grinding purposes while the wind generator is the one that produces electrical power.
What are the different types of wind turbines? Wind turbines are classified into two kinds based on their orientation:
DIY wind turbines are used to utilize the energy of the wind and a lot of work has been done to make them more affordable. However, buying a wind energy system still requires a large investment, but there is a way in which you can cut costs significantly.
This technique to cut costs involves making your own wind energy turbine. Wind turbines are available in large and small sizes. Building your own turbine means that you will be able to control costs to a certain extent.
Wind energy systems have different components like a generator, rotating shaft, …
