3. South China Morning Post quote March 14 th 2007 “” But wind power has one major problem: the exorbitant cost of power generation. At 0.5-0.6 yuan per kilowatt hour, real costs are roughly twice those of electricity produced in a conventional coal-fired power plant. Moreover, wind farms are not as reliable as traditional power plants. Vestas' turbines need a wind speed of 4 metres per second to produce power, and 15 metres per second to reach maximum output of two megawatts. The Dongshan turbines are active for roughly 35 per cent of the year, which is considered good for an onshore site. “” by Tom miller

4. Analysis on wind power. Wind power is a very mature technology,but still under used. Reasons : conventional wind turbine technology are designed for winds of at least 10 m/s At 15m/s the wind generator can be amortized in about 20 to 30 years at actual energy prices. wind turbines are very expensive and very large in size installation and maintenance are very complex.only professional trained staff can do it. so our research has focused on how to develop a technology that can solve these issues Small size wind generator that can work with low wind speed and that are easy to install and maintain

5. Performances of one of the biggest wind turbine manufacturer : Windpower of Denmark Real data are available from HK electric Lama wind generator

6. The red bar is the wind speed in Hong Kong and in the world in general

7. The blue bar is the wind speed in Tsim Tsa Tsui

8. The green bar is the wind speed in Ocean Park

10. A) Efficiency B) operating range C) performances for same surface and m/s kW

11. C) performances for same surface and D) for the same price m/s kW

12. And still these data about wind power do not reflect the reality. Wind does not blow at constant speed. Wind comes in “ GUSTS “. packs of air every 5 to 10 seconds. Example of wind Gust in a US wind farm

13. On a typical 3 floors 700 square feet house roof top we can install 60 to 100 turbines = 3 to 5 square meter. On a typical housing estate building we can install 500 turbines to 1500 = 25 to 75 square meter. (Lama wind generator = 2000 square meter (diam 50m) ) we just need 25 to 80 buildings to have the same surface and we can produce 2 to 10 times the same power (depending on Wind speed).

14. Next step : a 46 cm turbine for higher production and even lower cost 16 blades 8 blades

25. oops

26. What about showing a little bit of Hong Kong technology when 3 billion people are in front of their TV and demonstrating that we care about environment ?

29. Different possibilities

30. Water pump

31. Air pressure pump

32. Desalinisation by high saturated air

33. Desalinization by low temperature low pressure

34. Consumer product 8 turbines

35. Consumer product 20 turbines

36. Consumer product performances wind speed in m/s and power in watt

37. The first commercial application : to be build in March/April 2007 in Stanley. The Hong Kong SEA SCHOOL Mr William Hutchinson phase 1 setting : 360 turbines. 20 square meter rated 2.7 kW for 10m/s and 0.270 kW for 4.5m/s with 8 Batteries for storage of approx 8 kWh daily production :6.5 kWh. Annual production : 2.3 MWh. Saving in CO2 : 1 420 kgs. Phase 2 setting of 1240 turbines

41. WWF Hoi Ha Wan marine reserve Mr Eric Bohm

44. Mr Christian Masset Chairman CLEAR THE AIR What in practical terms this technology could bring to Hong Kong. How Green Groups could develop projects

45. WHAT IS SO GOOD ABOUT THIS SYSTEM? A) IT CAN BE MASS PRODUCED AND THEREFORE CHEAPER (10 TIMES CHEAPER) THAN THE OTHER EXISTING WIND TURBINES. B) IT WORKS WITH VERY LOW WINDS : STARTING AT 2 M/S WHERE CONVENTIONAL WIND TURBINES REQUIRES AT LEAST 7 TO 8 M/S IN HK THE AVERAGE WIND SPEED IS 5 M/S (18 KM/H OR 10 KNOTS) C) VERY HIGH EFFICIENCY : ABOUT 80% TO COMPARE WITH LAMA HK ELECTRIC WIND TURBINE OF 13.5 % D) IT CAN TAKE ANY SHAPES E) IT IS VERY LIGHT WEIGHT F) IT CAN BE INSTALLED ANYWHERE (THE OTHER NEED TO BUILD A ROAD ) G) IT CAN BE “INVISIBLE” IF WE USE THE SAME COLOR AS THE BACKGROUND. H) IT CAN OCCUPY USELESS LAND (EXAMPLE THE FENCE SEPARATING HK AND MAINLAND) I ) IT CAN BE USED IN INDIVIDUAL HOMES ON THE ROOF TOP OR BALCONY OR GARDEN J) IT IS VERY EASY TO MAINTAIN
