In October 2006, an earthquake knocked out all the electricity on the island of Oahu and closed down the Honolulu Airport, which had inadequate back-up generators.
Now the state of Hawaii is testing a series of wind turbines that should generate enough power to keep the airport operating should there be another emergency situation.
You can read the details of the project in the Honolulu Advertiser. But even if you’re not at all interested in kilowatts, turbines and voltage, take a look at the photo gallery that accompanies the article. As you can see from these photos, those wind turbines are really quite pretty.
