For decades, we've fantasized about watching paper-thin TVs, soaring hundreds of feet into the sky with personal jetpacks, riding in cars that drive themselves, and re-growing organs. The 21st Annual Best of What's New celebrates all of those dreams coming true. Take a look at Popular Science's December issue to learn about these achievements and 96 other breakthroughs that, whether long awaited or completely unexpected, are equally amazing. Photos, video, galleries, and more: it's Best of What's New 2008. For the Engineering Category -- the Wind-Power Tower, Bahrain World Trade Center, with three Norwin A/S Wind Turbine Generators is recognized as one of the Best, generating renewable energy while reducing carbon emissions!

ENGINEERING -- Bahrain World Trade Center -- Norwin A/S Wind Turbines

The first skyscraper to integrate large-scale wind turbines suspends three 225-kilowatt units between its matching 787-foot office towers. The turbines, which were completed in April, supply 15 percent of the electricity for the two buildings---roughly the same amount used by 300 homes.

To maximize energy output, the tapered towers funnel wind between them, creating a negative pressure zone behind the buildings that draws more air through the gap to increase wind speed velocity. This suction effect increases wind speeds by up to 30 percent at each of the 95-foot-long rotors to boost electricity production. It also redirects wind gusts hitting the tower by up to 45 degrees off center so that they hit the turbines at a nearly perpendicular angle for optimal electricity generation. www.atkinsglobal.com  and www.norwin.dk
