Energy for the New AgeAt least consider it!

A few nights ago we stopped at a gas station of a Portuguese highway to rest for a few minutes, and suddenly came across this little baby. We asked the gas station lady if she knew what it was, and she said she didn’t: it was just there, when she’d arrived for work that day. Then I asked if it’s even permitted to drop things like these unannounced. She said she didn’t know. But then again, removing it would be impossible Its size and shape, the fact that at least one wind farm is currently being created in the Algarve (south of Portugal), and a small specs sheet attached to it led us to believe to be one of the 3 blades to be attached to one of the turbines. This was later confirmed: Pics from the transportation company’s website: www.solenha.com That baby was at least 40m long, and if my memory serves me right, it weighed 80t [edit: according to Teratornis's comment, it couldn't have been 80t]. It was just beautiful You would have to be there to appreciate its magnitude though. PS: Some truck drivers pulling in to the gas station stared in awe, some cheering and bowing in a playful sign of rezpekt! my tumblr blog: sahbapasta.tumblr.com

Presentation about the challenges of blade design for wind turbines given at Windpower 2009, Chicago, May 5. Invented by Siemens Wind Power, the IntegralBlade® technology manufactures wind turbine blades in one piece using a closed process. The glass fiber reinforcement is laid out to dry using a special molding arrangement with a closed outer mold and an expanding inner mold. After completion of the lamination of the glass fiber, the epoxy resin is injected under a vacuum. Following this injection, the blade is hardened at a high temperature while still enclosed in the mold. Once the blade is hardened, it is removed from the outer mold, and the inner mold is collapsed with a vacuum and pulled from the blade. The result is a complete, seamless blade finished in one process. More: www.powergeneration.siemens.com

15 June 2008 A trio of Dunedin Engineers are looking to harness Otago’s strong winds to test their unique wind turbine. The single blade wind turbine can protect itself from being damaged in high winds, and it could even bring a financial windfall for energy efficient households.
