The Future of Energy
X-Wind-Technology
An energy source well known since 3000 years
• Wind availability for operation up to 90%
• Up to 3 x more efficient than common windmills*
• Grid independent, scalable and suitable
(for almost any territory)
• Operational costs comparable to fossil fuels*
The main facts

First flight with energy production Juli 11th 2012
Wind power plants usesthe same force which arenecessary for airplanesLifting force!
For example: Wind turbinewith 6 MW capacity ratingand a disc of 18.600 m², a capacity factor of 10-40% and an energy supply of5,2 – 21 GWh/a (depending on site)

Where does the power come from?
Die Kraft dahinter!
Lifting force
11
A plank in the windcreates a load
Lifting force
12
direction
This load (Fa) = lifting force,Is calculated byDifferent factors
Lifting force
13
direction
1. The wind speed (v)Slow wind = small load
Lifting force
14
directiondirection
Strong wind = high loadBut in square ! Double Wind speed means4 times of load !
Lifting force
15
direction
2. The face (A)Small face = low force
Lifting force
16
direction
Great face = great load
Lifting force

direction
3. The air density (r/2)Rare air = small load
Lifting force
18
direction
Thick air = high force
Remark: The air thicknes shifting close to ground (< 1000m) is insignificant!
Lifting force

4. The lift coefficient (CA)Bad aerodynamic = small force

Good aerodynamic = high force
Lifting force

Lift distribution on a rotor blade
V Rotor = 0 km/h V Rotor = 300 km/h
The rotor bladeleading edgesproduces:
The speed of the rotor blade heads to zero in the center.The lifting power squares with thethe wind speed. The reason whythe blade tips are responsible forthe main part of produced energy.
Where is the vast bulk from?
23
And what has this to do with airborne wind energy?
24
A cut through the rotor blade
25
Two tips together are comparable with a kite
26
Kites are „flying rotor blade leading edges“
27
The optimal flight patterns is a horizontal position of an 8.
How kites fly
Energy kites are able to fly in the optimal flight level ! High at weak wind, low if wind is to strong ! A conventionalwind turbine is not able to stoop down !
28
The horizontal flight pattern scheme

With increasing level not only wind speed is increasing but also the intensity

X-Wind power: Kites pulls powerhead = energy production, powerhead runs = give a lift or hold kite in the air

Wind energy costs comparable with fossil fuels
• 120 GWh/year = 1 NTS-plant• Starts at 2.5 m/sec, operates at 300 m
• 120 GWh/year = 60 x 1 MW windmill• Starts at 5 m/sec, operates at 120 m• Investment > 70 mil €
For the first time in history wind will produce energy comparable to fossil fuels!

Contribution to grid stability
• Technology is able to reduce its installed capacity within 10 sec. negative control reserve (switching from generation toengine mode)
• Is perfectly qualified for the provision of secondary and tertiarycontrol reserve
Therfore, technology can provide a substantial contribution tothe grid stability
