WINDGIANT ENERGY TOWERS -25 kW to 15 MW & Free running WINDGIANT POWER PLANTS, 10 kW to 1,5 MW

Patent Granted 1st International patented invention of Patent Priority AT 1238 - free-moving wind turbine ........................................................................................................................................................... Free-propelled wind turbine for power generation with flow accelerating turbine construction by constriction of all turbine flow channels on the Bernoulli, Venturi and Laval nozzles principle. The flow acceleration in the turbines is between 75% and 100% depending on hub height for all wind speeds. Therefore, increased energy output per turbine m2 area between 400% to 500%. The flow accelerator ends turbine designs are absolutely silent through the vortex forming vortex effect. Expansion sizes: 10 kW to 200 kW as small wind turbines Expansion sizes: 0,5 MW to 1,5 MW as commercial scale plants ............................................................................................................... 2nd International patented invention of Patent Priority AT 1646 - Wind Energy Tower ........................................................................................................................................................... Wind energy tower for energy with flow- accelerating venturi-shaped air flow in forward compacting device of wind inlet opening to horiontal current single turbine or twin-turbine at the tower bottom . In sequence is / are the wind turbine (s ) constructions with the narrowing turbines fluidic channels on the Bernoulli venturi and Laval effect after 1238 used AT . In the flow- accelerating venturi compacting energy tower , the air flow by 150% is - 200% accelerated. The increased performance gained energy per m2 of air flow are 500 % to 600 % of the conventionally used turbines or rotor blade to the prior art systems The installation of the flow accelerating turbines from AT 1238 to the already increased wind speed in the energy tower increased again by a further 75 % to 100 % at all wind speeds . As a result , the energy output per turbine m2 surface also increase by a further 200 % to 250 % Increase in performance thus at least 500% in the venturi-shaped energy tower x 200 % to 250 % of the additional acceleration of the flow- accelerating turbine design . Total increased performance increase over the three -bladed rotor blade systems between 1000 % and 1250 % per m2 air inflow In our energy tower the flow accelerator ends turbine designs by the turbulence generating vortex effect are absolutely silent . Expansion sizes: Expansion sizes: 25 kW to 150 kW as a small wind energy tower Expansion sizes : 300 kW to 15 MW as a commercial wind energy tower Installation options into existing silos, and in multi-storey residential buildings and skyscrapers .................................................................................................... Principle of operation: ..................................................................................................................... 1 Bernoullie effect: Daniel Bernoulli discovered the relationship between the flow rate of a fluid and its pressure. He found out that, in a flowing fluid (gas or liquid), a speed increase is accompanied by a pressure drop. .......................................................................................................................... 2 Venturi and Laval nozzles effect: Venturi discovered that the flow rate of a flowing incompressible fluid through a tube is inversely proportional to a changing pipe diameter. That is, the velocity of the fluid is at its greatest where the cross-section of the tube is smallest. After Laval: In the convergent part of the flow is accelerated. In the divergent part of the flow is further accelerated, pressure and temperature fall off from the closest compression point. ................................... www.windgiant.com
