When you're driving along the I-10 East toward the Broadway curve, you may see a giant dish off to the side of the freeway, pointed at the sky. TheArizona Department of Transportation
estimates that approximately 239,000 vehicles pass by this dish every day, yet most people have no clue what it is.
The site officially opened on January 13, 2011. The 75-foot diameter solar dish off the I-10 is one of many located throughout the Valley as part of the project. Each dish generates 200 kilowatts of power, and works by using turbine engines to take in compressed air heated by the sun, and then blowing the air out the back.
