The document discusses the potential for wind and solar energy projects in Rajasthan, India. Specifically: 1) Western Rajasthan has abundant sunshine, wind resources, and solar radiation, making it a preferred location for solar energy projects. The region receives over 325 days of sunshine per year. 2) Rajasthan has the infrastructure in place like transmission lines to support large solar and wind energy plants. It also has rich mineral resources that can support energy project development. 3) A hybrid wind and solar energy system called "Wind from the Sun" is described that uses solar heating to create wind inside pipes that drives turbines to generate electricity. This system aims to provide more consistent power than solar or wind alone

3. Rajasthan – Preferred State for Solar
Energy
 The state in its western part blessed with abundant
natural resource i.e. optimum sunshine and wind
 With more than 325 days of sunshine every year
 The state has the highest solar radiation in the country
 Jodhpur, popularly known as the SUN CITY of India
 Assured power evacuation arrangements in place.
Setting up 400 / 220 / 132 KV network for solar and
wind energy based power plants in progress.

4. Rajasthan – Preferred State for Solar
Energy
• Rich in mineral resources, viz. marble, granite,
rock phosphate, zinc, lignite, Lime stone steel
grade etc.
 Per Capita electricity availability – 561 units
 Vast potential for Power Generation from
Wind, Solar , Biomass, Petroleum and Natural
Gas in Western Rajasthan.

PLANT

8. INTRODUCTION
Wind From The Sun is a new technology for
obtaining power from the sun and wind.
This hybrid system turns the sun's light into
heat, then uses that heat to create a wind
within a horizontal large-diameter pipe.
The wind inside the pipe is converted into
electric power using a series of wind turbines.
Provides a greater degree of control and
predictability.

9. SOLAR COLLECTOR
MATERIAL
 converts the energy from sunlight into heat.
Must have low reflectivity, dark color.
Does not need to have high thermal mass.
Increase in temperature drives the entire
system.
Made of black ceramic gravel.
The higher the temperature of the collector,
wind power the system can generate.

11. SIZE :-
Optimum size depends on a number of factors .
It is similar to solar chimney power plant.
Solar chimney power plant-solar collector-.
4000m (dia) & 1500m high-600GWH/year
A wind from sun power plant is best located in
regions receiving 2300KWH/m2
/year.
Energy of the system is given by multiplying
area by amount of solar radiation.
Sufficient increasing area results in increased
power output

12. TEMPERATURE
Must be hotter than the surrounding land.
For sea-breeze difference is 100
C – wind speed
is 12m/s.
Hotter towards the centre & cooler towards the
perimeter. Large collector has fewer
perimeters/unit area.

13. AIR MOVEMENT
• HOT AIR RISES:
No. of factors makes the rising column
narrower.
 The collector is hotter in its centre making the
air hotter & rises faster.
The hotter air towards the centre rises faster
than that over the perimeter.
The rising air at the centre meets with least
resistance.

15. AIR CHANNELS
Air moves from high pressure to low pressure,
creating a wind within the pipe.
The amount of wind power generated by this
system depends on the air pressure difference
from the center of the collector to the
surrounding land.
The sun is higher in the sky and gives more
sunlight in the summer than in the winter.

16. The hot air rising from the center of the collector
creates and maintains a low pressure area in the
center of the collector.
The pipes have a constant difference in air
pressure from one end to the other. This difference
in air pressure moves air through the pipes.
Each pipe has pressure-staged wind turbines
which present a kind of obstacle to the air
movement.
The wind turbines remove mechanical energy
from the wind in the pipes and convert it to
electricity.

17. WIND TURBINES
 A series of very large wind turbines within
the pipe turn the wind into electricity with a
high degree of efficiency.
Operates over a wide range. When the speed
increases the turbine’s rotational speed increases.
Hence results in greater available.
Swept area is roughly proportional to power output
the output would be increased by 40% by using one
large wind turbine, instead of 7 smaller ones

19. CONCLUSION
This type of system produce power
Air must move from high to low pressure
through the air channel & wind turbines.
Has not been built & tested to determine how
much power will be produced.
Alternate Design: to increase efficiency, place
air channel so that one end is over a large body
of water. The water will be much cooler than
the collector and will increase the air pressure
difference along the air channel.
