WIND ENERGY TURBINE IN THE WORLD [【組圖四】

Wind Turbines

Southwest Windpower AIR-LX-1 Air X Land 400W Wind Turbine The Air X is the best selling wind turbine in the world. Priced aboutthe same as a large-scale photovoltaic module, and about as easy toinstall, an AIR is capable of producing several times the energy!Maintenance-free performance, easy installation, and high output makeAIR ideal for virtually any remote battery charging application. TheAIR is designed to be used in combination with photovoltaic modules tobalance system energy output during times of seasonal fluctuations. Noroom for a tower? AIR's compact design make it ideal for roof topmounting. TheAIR's blades are made of a carbon fiber reinforced composite thattwists as the turbine reaches its rated output. This twisting effectchanges the shape of the blade, causing it to stall, limiting the RPMof the alternator protecting the AIR from damage in high winds. TheAIR's brush-less alternator is optimized to match as close as possibleto the cubic energy in the wind. It is constructed with Neodymium IronBoron permanent magnets for superior performance and maintenance-freeoperation. The electronics perform several functions toassure maximum output and safety for the user. The control electronicsmaintain a load on the alternator at all times to insure the turbinenever over speeds, regardless of the condition of the battery. As thebattery is charged, the sophisticated regulator periodically checks theline, correcting for voltage loss and monitoring charge rate. Once thebattery has reached its optimum charge level, the regulator shuts thecurrent off, preventing the battery from being overcharged and slowingthe blades to a silent spin. Features: Unprecedented 3 YEAR WARRANTY Simple rooftop installation; no tower necessary Carbon Fiber Composite Blades Aircraft quality aluminum alloy castings Exclusive Brush-less neodymium cubic curve alternator Sophisticated internal battery charge regulator Maintenance-free - Only two moving parts ExclusiveAuto-brake-feature that slows the AIR to a silent spin when thebatteries are charged thus extending bearing life and reducing noise. High Wind Safe Mode - Automatically slows turbine in potentially damaging winds and reduces noise. Neighbor Friendly.

Great Lakes Science Center - News Release - May 4, 2006- The first Cleveland lakefront wind turbine is currently beinginstalled on the front lawn of the Great Lakes Science Center.Originally a community project of Leadership Cleveland and SustainableCleveland, the turbine is made possible through collaboration with TheCleveland Foundation, Parker Hannifin Corporation and the LubrizolCorporation. The Science Center intends to use the turbine as anaccessible and tangible way to demonstrate wind power technology,create a greater public awareness of renewable energy and educate itsvisitors and the public about the benefits of alternative energy forour region. "We are delighted to see the installation of the first windturbine on the southern shores of Lake Erie in front of our wonderfulScience Center.  We hope this will be the harbinger of a new advancedenergy manufacturing industry which will help secure Northeast Ohio'sfuture economic prosperity," said Ronald B. Richard, president andchief executive officer of The Cleveland Foundation.

 

The turbine is expected to provide an estimated seven percent of theScience Center's annual electrical needs, but energy cost-saving is notthe primary objective according to Science Center President andExecutive Director Linda Abraham-Silver.  "The project brings ourmission of demonstrating the interrelationship between science, theenvironment and technology to life," said Abraham-Silver.  "We decidedto install the turbine on our front lawn for its visibility, forpedestrians visiting North Coast Harbor attractions, motorists on theShoreway and downtown workers and visitors.  We want to raiseawareness, engage curiosity and encourage discussion, just as we dowith our indoor signature exhibits and programs."   The Science Centeris also developing related exhibits for indoor installation includinginterpretive panels on the science and technology of the turbine, anexample turbine blade, and a touch screen kiosk with visitor friendlyinterface providing both real-time and historical data visualizations.Kiosk data visualizations include wind speed, power generated overtime, and the amount of carbon dioxide not generated for the powerequivalent.

Cleveland Public Power and Phillips Electric areperforming the necessary electrical work, which will take approximatelyone week to 10 days to complete.  Once power is established and thepole, engine and blades are installed, the turbine will be tested,balanced and started. This will take an additional week, weatherpermitting.  The turbine needs a breeze of eight miles per hour (mph)to generate power and at 31 mph it achieves its peak output of 225kilowatts.  The turbine?s total height is about 150 feet which makes itapproximately 60 feet taller than the Science Center and approximately13 feet shorter than the Browns Stadium.

 

Cleveland Public Art (CPA) in partnership with the Science Centercommissioned New York artists Allan and Ellen Wexler to create apermanent educational public art installation surrounding the windturbine. Together, the turbine and artwork will make a powerful visualstatement about Northeast Ohio's growing commitment to environmentalsustainability. Construction is scheduled to begin this summer withcompletion anticipated in the fall.

The Great Lakes ScienceCenter, now in its tenth year, is one of the nation?s leading scienceand technology museums, featuring more than 400  signature  hands-onexhibits, themed traveling exhibitions, daily demonstrations and theawe-inspiring OMNIMAX
