3.  The use of wind energy to propel boats dates as far back as 5000
BC, and wind-energy conversion systems in the form of windmills
have a recorded history from 200 BC.The first horizontal-axis
windmill for electricity production was built in Glasgow, Scotland,
in 1887 by Professor James Blyth of Anderson's College, Glasgow
(now Strathclyde University). In 1931 in the United States, George
Darrieus invented and patented the first vertical-axis wind turbine,
known as the Darrieus turbine.The 1930s became a turning point
for the wind power generation industry as several wind turbines
with high electric power-generating capacity were built. In 1941
the world's first megawatt wind turbine was built inVermont,
United States, and was connected to the power grid.This turbine
had 23-m (75-ft) blades and weighed 220 tonnes (240 tons). It was
not until the late 1970s, because of the fossil-fuel energy crisis,
that wind turbines started to spread rapidly across the globe, a
trend that has continued to the present.

4.  Invelox technology was invented by Dr.
Daryoush Allaei.
 Invelox is a wind injection system.
 It works by accelerating the wind.
 A large intake captures wind,funnels it down
using tapered pipes leading to a venturi section
and finally wind exits from diffuser.
 Turbines are placed inside the venturi section of
the invelox.
 The turbine converts kinetic energy into the
mechanical rotation and with the help of
generator we developing the electrical power.

5.  It works on hydropower principal.
 It separates the turbine from the intake like a
hydropower plant.
 In which to build pressure and use wind
density and gravity to reach turbine at high
kinetic energy level.
 Wind is concentrated and further accelerated
in the Venturi Effect* section of the
INVELOX system.

6. Invelox system consist of components:
 Intake system
 Pipe carrying and accelerating wind
 Boosting system of wind speed
 Wind energy conversion
 Diffuser

7.  The Venturi effect is the
phenomenon that
occurs when a fluid that
is flowing through a
pipe is forced through a
narrow section,
resulting in a pressure
decrease and a velocity
increase.

8.  Wind is captured at the top of the funnel
shaped INVELOX system.
 The omnidirectional intake area allows wind
collection from any direction.
 Wind is funneled through the system.
 Wind is delivered to the turbine/generators to
convert the accelerated wind to electrical
power.

12.  Economical of wind turbine power generation.
 Low Cut-inWind Speed .
 Reduce land use.
 No impact on bird.
 Reduce distance from grid.
 Turbine reliability is more.

13.  For wind power generation.
 Power generation will be vary with wind
energy.

14.  Thus,it is a better solution for increasing
efficiency in commercial renewable power
generation applications its also has good
architecture and can be installed ground level
application.
