Aerodynamic principle

Aerodynamic principle

In this document, I want to give you a short overview about the different aerodynamical principles based on which wind turbines and EneBird Wind Power Plants work. You won't need any special knowledge in physics to fully understand my invention and you will understand exactly how wind turbines work and why the EneBird technology is so superior! Wind blowing over a plane ground forms streams, it becomes streamlined. Air that is streamlined has the lowest internal energy level, which is why it is formed automatically and air that was stirred up, will eventually become streamlined, that is, fall back to the lowest internal energy level again. Now, when streamlined air hits an object, let's say, a tree's crown, the stream-line is destroyed, the air is stirred, small turbulences are all around - and the ability for another high energetic impact is reduced. In nature we see this principle when streamlined, fast wind is "crushed" by the outer trees of a forest, the inner ones remain untouched by the original high impact and storm is less likely to harm them. Crushed air is flowing on average in the same direction exactly as fast as the streamlined air before the crash, but creates less pressure on the objects on which it impacts.

The energy a wind-turbine collects from the wind, thus stems from this impact streamlines have on the rotor blades. Instead of the tree, the stream-lined air hits the blade and is twisted and whirled around. As they push the rotor into motion, they also crush the neat streamlines into chaotic swirls, dramatically raising their internal energy. One can understand a rotor as a stream-line-crusher. This chaotic, high-energy-level air, curling and whirling around has less pressure and thus becomes softer against the next obstacle. Good for tree protection bad for wind-turbines, as placing them near each other will obviously reduce their efficiency drastically. Today, there are basically two kinds of wind turbines. One has a propeller and horizontal axis, the other one has more wing-like blades with a vertical axis.

Both are, in the view of natures principles, obstacles in the way of the wind, so they work better, the more streamlined the wind blows, that is, the further they are from other obstacles. The implications are: 1. wind turbines work better, the higher they are placed, as wind is more streamlined there. 2. As they destroy the stream-line structure like a fixed obstacle (tree), turbines shield each other and cannot be clustered. They need to have huge distances between each other to let the air streamline itself, that is fall back to the lowest energetic level.

For those reasons, wind energy has not reached individual use: placing a wind-wheel into your garden near the ground will not give you much energy if any at all. Small wind turbines near the ground get a lot of crushed air and thus are only usable at places with high wind speeds. At such places, the maximum acceptable windspeed is quickly reached and the turbines must start braking or stop completely to withstand too high wind-speeds. To really generate acceptable amounts of energy, the pylons must be high and that again has an implication: the noise of the blades and generator sitting on top of the pole is heard in far distances. That is another serious implication: the destruction of the air-structure by the blades creates NOISE. Lots of noise! To conclude, traditional wind turbines work by destroying the stream-lined structure of the air and create a chaotic curly air-structure. By doing so they raise the energy-level of the air in the area behind them (=lower the air-pressure) and get a portion of the energy-rise back as kinetic energy put into the rotation of the blades. EneBird works on a completely different principle, the Waved Stream Lined Air Principle that birds use to fly and that does not have the mentioned disadvantages plus it is much more effective. This is important to understand: What is true for wind turbines, is not true for EneBird technology Wind Power Plants (EWPP). To name a few differences: - EWPPs can be placed close to the ground - EWPPs can be placed near trees, in small gardens - EWPPs can stand close to each other and then extract MORE energy from the air (that means: clustering is not only possible but favorable!)

Anyway, the technology is not complicated to understand, and I will show it completely to you! Before I describe you the EneBird Wind Power Plant itself, I will explain the Waved Stream-lines Air principle to you to make you understand, how the EWPP works. The bird is created by nature in such a way that the air flows around the body keeping the air's energetic level or lowering it to the prospect of the bird, by flattening the air-curls with its feathers. The bird can fly in curled and in stream-lined air. Flying in turbulenced air is less calm but no problem for the bird as it does not crush the stream-lines but builds up waved stream-lines from

crushed and stream-lined air alike. The wings of the bird flatten enough air with the feathers so that turbulences do not affect his ability to fly. As the bird moves its wings, the air is smoothed into waves and streamlined, not stirred and crushed. Instead of creating destruction to the air structure, the bird applies harmony and the result is waved stream-lined air. This is extremely effective, as you can see by watching a bird. Airplanes that fly up and down and up and down fast, create such waved stream lines air as well and it will be crushed apart by the huge amounts of energy the airplane would receive - so this is a fatal mistake all pilots must learn to avoid. The EneBird Wind Power Plant works like the flight of a swift, and it takes the harvested energy out by means of a generator. As any kinetic impulse effects both sides, the wave the EneBird Power Plant creates and swings on, presses it into motion and kinetic energy into the system. But, by creating waves instead of noise and chaos, we do not shield any other EWPPs standing near, instead they ride on this same wave and swing even more! Actually, clustering EWPPs will result in huge, stream-lined waves that will give us even more energy from the wind than the single EWPP and still no noise! Instead of building very high pylons with noisy generators on top, to be heard in far distances, we can rather keep lower to the ground and create fields with EneBird Wind Power Plants for very rich energy harvest. In the EWPP, the generator is sitting on the bottom and can be easily muted by noise protection. Generators can even be below ground level, so that their noise-emission would be completely absorbed. And what happens if there is too much wind? The wind turbines must start braking using up brakes shoes. Without brakes, the crushing of the air-stream would crush the whole machine! The turbine would be destroyed and fy apart. Another way is to tlt the blades, which is technically very challenging. EneBird needs to deal with the too much of wind energy as well and as it harvests more energy from the wind, as it is more effective, it reached the point of more than enough wind energy with lower wind-speeds than wind turbines. But it does not need to brake, it simply shifts the phase between the swinging elements and thus reduces the amount of energy to be harvested from the strong wind to what is actually needed. So, if there is more than enough energy in the wind, we harvest only what we need! Now you start to understand how big the advantages of the Enebird tech are: quiet & effective, it can be assembled close to the ground, just high enough that does not hit people in the head. It accepts curled wind, so it can sit low enough in gardens to not annoy neighbors. Trees do not shade it, correctly combined, trees can even make the output higher! The EWPP is no obstacle that destroys the streamline structure of the wind to get energy out of that destruction instead, it harmonizes with the wind, making it even more streamlined, it flies in the

wind and it looks like a glider rising and falling and rising again, always with the same frequency, independent of how strongly the wind blows. A glider flying this way would be crushed, as we learned before, but as we take the energy out from the system and turn it into electricity, we have a very effective device to harvest kinetic energy from the wind. The wings move in low frequency (about one to five times up and down within one second) that does not create any sound, nor does it endanger any kind of flying animals or people below or around. But it looks hypnotic-fantastic; it can be designed in many ways and can be placed close to where the electricity is needed. The Enebird Wind Power Plants can have many designs and become artworks of artists, can use light-effects and be placed nearly everywhere for many purposes. www.enebird.com
