Fast Winds at the Bahrain World Trade Center

Tapered towers funnel wind between them and meet a sizeable chunk of the energy needs of one of the world's tallest skyscrapers

The first skyscraper to integrate large-scale wind turbines suspends three 1,200-megawatt 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. [ Read Full Story ]

Readers Ask . . .

Is it possible that wind power, when developed on a large scale, will disrupt natural wind patterns?

PopSci reader aaronmrosen wonders: "when it comes to wind farms, can too many props actually slow down the wind, and cause a change in weather patterns?"

What do you think? Wind power: good or evil? Discuss in the comments section.

Wind-Powered Town

One Midwestern city etches out a future of its own design

As researchers find new technologies to power the world of the future, the answer may be blowing in the wind.

Across the country, wind-generated power has been showing the potential to be a significant energy generator. Last week, Rock Port, Missouri, became the first city in the United States to generate its electricity entirely through wind-powered technology. Meanwhile, Texas, known for its oil connections, has become the nation's largest producer of wind-powered energy and is investing almost $5 billion in a wind power project.

Wind Power on the Go

A palm-sized turbine provides a recharge on the go

digg_url = 'http://digg.com/gadgets/Wind_Power_On_The_Go';
I've seen hand-held solar chargers before—the Solio immediately comes to mind—but I've yet to see a functional wind-powered hand-held charger. Enter the HYmini. It's palm-sized, comes in three colors, costs 50 bucks, and can charge your gadgets with nothing but a stiff breeze. Well, almost. While it's a welcome idea, on closer inspection, the feature set isn't all we'd like it to be.

The Wind Dam

An architect plans to sling a giant sail over a lake in Russia. Is it the future of wind power—or renewable snake oil?

One common complaint about wind turbines is that they blemish the scenic countrysides and coastlines where they perch. Now an architect in London has an attractive solution. The wind dam, a giant swath of fabric connected to a turbine, looks more like a Christo art installation than a power generator.

Wind Power Reconsidered

Innovations and steep gas prices may at last kick-start wind energy in the U.S.

Next spring, General Electric will inaugurate the Arklow Bank Offshore Wind Park, a wind farm just off the eastern coast of Ireland. The plant is already operating at nearly full capacity, its seven massive 3.6-megawatt turbines cranking out enough electricity for 16,000 households. Arklow Bank is Ireland´s first offshore wind-energy project and Europe’s 19th, with at least 10 more slated to go up in 2005.
