Scientific background

The Wind Lotus^TM turbine. The most aerodynamically advanced in its class. This page will explain important facts about wind turbines to you, and answer some common questions.

Types of Turbines

There are two basic types of wind turbines: vertical and horizontal axis. In general, each type has certain advantages and disadvantages. The Wind Lotus^TM is a vertical axis turbine. Vertical axis turbines are very quiet, safe, and do not need to turn towards the wind to maximize their power output. This makes them more economical for you.

Horizontal axis turbines tend to be more powerful per square meter of wind, but are noisier, vibrate more, present dangers to people and birds, require more empty space around them, and need to be elevated away from people.

Turbines can also be classified in two other ways: lift turbines and drag turbines.

Drag turbines simply rotate from the push of the wind. They start easily, but cannot move faster than the push from the wind.

Lift turbines are aerodynamically designed to rotate faster than the mere push of the wind but this class has more difficulty starting.

The Wind Lotus^TM, with its unique design, has the advantages of both types. The patent-pending aerodynamic shape as seen on the left is a computer model of the wind speed and one of the reasons for its superior performance. In addition the Wind Lotus^TM has five blades, whereas almost all lift turbines, whether horizontal or vertical, have three.

This means more starting power, better balance, and minimal noise.

The aerodynamic design of the Wind Lotus^TM increases the velocity at the point that the wind hits the blades and can produce more power than a physically larger turbine.

Is your site cost-effective?

In general, most locations have a good breeze of 3-5 meters per second for at least several hours per day. That is adequate for a reasonable return on investment. The Wind Lotus^TM has a lower cut-in speed than other turbines; as a result, your cost-effectiveness increases. The cut-in speed is the speed at which the Wind Lotus^TM starts to turn and produce electricity. The aerodynamic design improves its performance over other turbines so that not only does your turbine produce more power, but also the turbine starts turning at a lower wind speed.
