ACKNOWLEDGEMENTS
SINCE 2006, Dr. Dennis Leung AND Dr. Michael
Leung, FROM THE HONG KONG UNIVERSITY, LEADING
EXPERTS IN RENEWABLE ENERGY, HAVE SUPPORTED AND
WORKED ON THE MOTORWIND
Dr. Dennis Leung
Dennis Y. C. Leung received his B.Sc. (Eng.) in
1982 and Ph.D. in 1988 from the Department of
Mechanical Engineering, the University of Hong
Kong. After obtaining his Ph.D., he worked for
the Hong Kong Electric Co. Ltd. as an
Environmental Engineer. He returned to the HKU in
1993 as a lecturer and course coordinator of
environmental engineering. He is currently an
Associate Professor with expertise in air
pollution control, dispersion modeling and energy
conversion. Dr. Leung is a chartered and
registered professional engineer, a fellow of
IMechE, Institute of Energy and HK Institute of
Acoustic, and a corporate member of HKIE. He is
the past Chairman of the Institute of Energy (HK
Branch), an editor of the HKIE Transactions, and
a regional editor of the Journal of Global
Environmental Engineering.

ACKNOWLEDGEMENTS
Dr. Michael Leung
Dr. Michael Leung received his B.Sc. from Oregon
State University in 1990, M.Sc. and Ph.D. from
the University of Florida in 1992 and 1995,
respectively. He subsequently conducted full-time
research as a Post-Doctoral Associate at the
University of Florida and as a Research Associate
at the University of Hong Kong. Between 1997 and
1999, he served as the Energy Conservation
Manager in Cable Wireless HKT. He then joined
the Department of Manufacturing Engineering and
Engineering Management at the City University of
Hong Kong as a Lecturer for two years. He joined
the Department of Mechanical Engineering at the
University of Hong Kong in 2002. His research
interests include indoor air quality, energy
efficiency, and heat transfer.

THE MOTORWIND - INTRODUCTION
Born in the year 2005, The Motorwind is a
totally new technology, still at the experimental
stage. In view of the first presentations, the
Hong Kong University decided to fund the project
and opened a research program to get more
accurate data and theorize the process.

GENERAL PRINCIPLE
Wind turbine technology is very mature and very
well documented . There is many companies
manufacturing wind turbines and there is already
many sites exploiting wind energy . All wind
turbines use the same design China has the
objective of producing 30 000 MW by the year 2020
using wind turbines
9
HOW MUCH ENERGY CAN WE GET FROM WIND?
Pe ½ D2 x V3 x E in watts example if D
30 meters V 10m/s E 20 average Pe 90 KW .
In the above equation, D represents the diameter
in meters , V represents the wind speed in meters
/second and E represents the efficiency .
10
WHERE ARE WE TODAY?
WIND ENERGY IS STILL VERY EXPENSIVE IN TERMS OF
INITIAL CAPITAL INVESTMENT . NATURAL GAS POWER
PLANT 500 TO 600 US PER KW WIND ENERGY
1500 US PER KW THE OTHER PROBLEM IS THE
EFFICIENCY . WIND TURBINES NEED WINDS OF AT LEAST
10 M/S TO GENERATE ELECTRICITY AND THEY HAVE TO
BE SHUT DOWN FOR WINDS OVER 30 M/S . THE AVERAGE
EFFICIENCY AROUND THE WORLD IS ABOUT 20 WITH A
TOP IN TASMANIA WITH A 40 EFFICIENCY. SO THE
PROBLEM IS QUITE SIMPLE TO MAKE WIND TURBINES
MORE ATTRACTIVES BE CHEAPER AND MORE EFFICIENT

11

TO ANSWER
A) MANUFACTURING PRICE . SINCE THE TECHNOLOGY
USED FOR MANUFACTURING WIND TURBINE IS CLOSE TO
AERONAUTIQUE ,MASS PRODUCTION TECHNICS CAN NOT BE
USED . B) DUE TO THE ACTUAL DESIGN AND WIND
ENERGY AVAILABLE THE EFFICIENCY CAN NOT BE
IMPROVED . We have therefore tried to solve
this problem by changing the size and design
. A) the actual design of wind turbine uses the
two or three blade propeller because of the
speed involved and weight limit . The propeller
design is the most suitable for high speed tip
.(like a airplane propeller )but perform very
badly for low speed . The multi blade design (8
to 12 blades) performs very well if the rotating
speed is kept low B) the best size for a mass
production by injection machine is about 0.50 m

One turbine (clockwise)

Yellow turbines rotate clockwise and green
turbine anti clockwise
15
Based on that design we can collect energy from
winds as low as 1 or 2 m/s . the efficiency
increases to about 70 (instead of 20) . the
assembling and maintenance is very low . If there
is a problem with one of the turbine we just
replace it . The production cost of one turbine
is only about 4 US . We can build complete walls
of turbines of any shapes . For the same power as
an actual wind turbine the manufacturing cost of
a turbine wall is about 20 times lower . Due
to the space between two turbines ,the frame
holding the turbines can deform giving a great
flexibility . Energy can be collected on any part
of the turbine wall . turbines can be
injected in different materials and colors
(including transparent ) .
16
By using different colors we can create a new
media

Since we are currently investing all our
resources in our new wave energy technology we
did not proceed yet with the MOTORWIND project
. We just need to make the molds and start real
scale testing . The estimated cost is around 2
million HK . We are interested to find a
partner who can help us to develop this
technology . The business potential of our
technology is extremely high because we can
power also very small units like individual
housing and at a cost that poor countries can
afford . Collaboration with United Nation or
World Bank or third world countries government
could be very productive .
