Abstract:
The invention provides wind power generation system for surface transport. The invention specifically uses bleeding high velocity air due to motion of automobiles by means venturi inlet (101) and directing it through venturipipesto drive an impeller (103). The impeller thereby driving a generator (104) to generate either variable AC power or DC power which is processed to generate regulated power. Each single system may be configured in a plurality of series, parallel, series-parallel configuration to get more power. In case of automobiles part of the outlet air from venturi can be allowed to pass through the engine thereby reducing the engine temperature. This helps in reduction of usage of coolants and reduces maintenance cost. Further the cool air from the venture outlet may be circulated to the air conditioned interiors of a vehicle on road,a rail car, In case of electric loco in a preferred embodiment outlet of venturi can be used for air circulation inside the loco pilot cabin. This ensures reduction in cabin temperature and comforts to loco pilot.

Abstract:
The invention relates to a traction kite control system that allows precise and reliable positioning of traction kites or rotating flyer wheels. Normal traction kites have 2 to 4 traction ropes for steering. In the device according to the invention, the pulling force should be adjustable in addition to the steering. To minimise the number of ropes, a plurality of traction kites are connected by means of connecting ropes (3) to form a group. Each individual traction kite within said group has only 2 traction ropes for transmitting and controlling the pulling force of the traction kite. The individual traction kites are connected to each other in a net-like manner by means of connecting ropes (3). To control the position of the respective group of traction kites or flyer wheels, positioning traction ropes (4), which run obliquely downwards, are braced at the outer traction kites in a similar manner to a known domestic tent. The traction ropes (5) then virtually assume the function of known tent bars. The traction kite group can also execute horizontal movements in the form of a horizontal figure of eight or also circular movements. Then only the individual screens rotate according to the movement direction and/or wind direction with the aid of rotary bearings (8) and rope rotators (9). The wind direction can be determined by comparative measurement of the individual pulling forces and lengths of the respective positioning traction ropes. By changing the relative pulling force compared with adjacent screens and the traction ropes, the position of the traction kite group can be adjusted to the wind direction and/or the desired movement direction. The distances between individual traction kite groups can then be minimised.

Abstract:
Die Anmeldung beschreibt eine Zugdrachensteuerung, welche ein genaues und zuverlässiges Positionieren von Zugdrachen oder rotierenden Flügelrädern ermöglicht. Normale Zugdrachen besitzen zur Lenkung 2 bis 4 Zugseile. In anbei beschriebener Vorrichtung soll neben der Lenkungssteuerung auch die Zugkraft einstellbar sein. Um die Anzahl der Seile zu minimieren, werden mehrere Zugdrachen mittels Verbindungsseilen (3) zu einer Gruppe verbunden. Jeder einzelne Zugdrachen innerhalb dieser Gruppe besitzt nur 2 Zugseile zur Übertragung und Steuerung seiner Zugkraft. Die einzelnen Zugdrachen sind netzartig mittels Verbindungsseilen (3) untereinander verbunden. Zur Lagesteuerung der jeweiligen Gruppe von Zugdrachen oder Flügelrädern werden an den äußeren Zugdrachen zusätzlich schräg nach unten verlaufende Positionierungszugseile (4) abgespannt ähnlich dem bekannten Hauszelt. Die Zugseile (5) übernehmen dabei quasi der Funktion der bekannten Zeltstangen. Die Zugdrachengruppe kann auch horizontale Bewegungen in Form einer liegenden Acht oder auch endlos kreisende Bewegungen ausführen. Dabei drehen sich lediglich die einzelnen Schirme entsprechend der Bewegungsrichtung bzw. Windrichtung mit Hilfe von Drehlagern (8) sowie Seilwirbeln (9). Die Windrichtung kann durch Vergleichsmessung der einzelnen Zugkräfte und Längen der jeweiligen Positionierungszugseile ermittelt werden. Mittels Veränderung der relativen Zugkraft verglichen zu benachbarten Schirmen bzw. der Zugseile kann die Lage des Zugdrachenverbundes der Windrichtung bzw. der gewünschten Bewegungsrichtung angepasst werden. Die Abstände zwischen einzelnen Zugdrachengruppen können damit minimiert werden.
