The Breezemill is a vertical-axis wind turbine that can generate power from low wind speeds starting at 3 kmph. It is designed to harness power from breezes which makes it suitable for urban, semi-urban and rural areas. Some key features include being omnidirectional, self-regulating, and having a telescoping tower that allows for easy maintenance by lowering the turbine to ground level. It has several advantages over traditional horizontal axis wind turbines including being able to generate power in low wind speed areas where 80% of India experiences breezes. The Breezemill has the potential to provide power to millions of households currently without electricity.

1. Breeze Power Mill
Empowering India
Patent Number 264499

2. What is the Breezemill?
1. A vertical-axis windmill that generates Power at low wind-speeds starting at
3 kmph (0.8mtrs/second).
2. Specially designed to generate power from a breeze.
3. Ideal for urban, semi-urban and rural habitats where buildings and
Geographical placing do not allow for high wind speeds
4. Generation can peak at 7 to 9 km/hr wind speed and continue at higher
windspeeds.
5. Completely idegineous in design, concept and construction.

3. Technical details - Performance data
1. Patent Number 264499
2. Confirmed starting wind-speed for power generation is 3 Kmph
3. Tested for power-generation and durability across seasons in dense urban
area for three years.
4. Scalable model based on power requirement (3 kW to 100 kW)
5. Designed for low-cost manufacturing, mass-production, and easy
maintenance.
6. Specially designed to generate power in areas where average windspeed is 3
km/hr

4. Technical Features
• Omnidirectional. Works irrespective of wind direction.
• Self regulatory, finds a balance between wind speed and load.
• Absorbs maximum power of the wind.
• Cost effective.
• A well designed telescoping tower that allows the user to lower the
Breezemill to ground level for maintenance purposes.
• Can be used as hybrid system with solar panels.
• Specially designed low RPM permanent magnet generator
• Designed for a 15 year life span.
• Can be designed for low, medium and high windspeed areas
• Maintenance once a year

5. Traditional Windmill Vs Breezemill
Traditional windmill
• Operates at 9.5-50 Kmph
windspeed
• Needs to face incoming wind to
be productive
• Hydraulically controlled blade
pitch and blade yaw required
• Blade pitch requires adjustment
for different wind speeds
• Works like a fan/ propeller
• Maintenance to be done in situ,
needs specialists
Breezemill
• Operates at 3-95 Kmph windspeed
• Omnidirectional - faces into the
wind at all times
• Has paired blades that open and
close by the wind power itself
• Automatically adjusts to wind
speed and load
• Works on drag principle
• Maintenance done easily by
lowering machine to ground since
it is mounted on telescoping tower.
• Maintenance can be done easily

Comparative Chart for wind turbines:

7. USP
1. Indigenous Design and Manufacture
2. Game Changer, Paradigm Shift
3. Simple Construction and Easy Installation
4. Possibility of Developing Mini Grids, which can be connected to Main
Grid.
5. Excess generated Power can be sold back to Grid.
6. No environmental Impact
7. No noise pollution.
8. Power generation from 3 KVA to 50 KVA

8. Some Target Areas
a. Smart Cities
b. Rural Areas,
c. Hilly Areas
d. Coastal Areas
e. Islands
f. Remote and border Military and Gov. Establishments
g. Corporate CSR
h. Model Villages
i. As a Hybrid Solution along with Solar

9. Why Breeze Power
a. Generates power in a breeze. More than 80% of India is low wind speed
or breeze areas.
b. 80 million homes without power, i.e. approx. 360 million people.
c. No grid connection, using Kerosene which has high carbon emission and
is polluting and causes chronic illnesses.
d. 20 million homes, i.e. 95 million people get less than 4 hours of
electricity per day
e. LED Initiative of the Got, further makes Renewable Energy viable and
attractive.
f. Lower capital cost of Breezemill

10. WIND DISTRIBUTION IN INDIA
1. The white and light
blue areas are the
target areas.
2. If those areas are
brought into the
wind generation
map we are looking
at a great increase in
generative area by at
least 3 times the
areas under red

11. Cultural Revolution
Potential to empower and create Lakhs of SMART
VILLAGES, TOWNS AND CITIES - reverse the migration
Sharing of power and collective empowerment will lead
to care, unity, empathy, collaboration and healthy,
cultural exchange. Decentralised power system.
