Now, we see the most exciting urban innovations to show you exactly how they'll improve your city's infrastructure . Lighting Up The Night Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees' swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees' outer LEDs. Thinking Outside The Box As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents' health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition. Waving Hello To Clean Energy Cities that don't receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption , electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs. Question: What is the special infill used to do? - To make the trees beautiful. - To produce electricity. - To help the trees' swaying. - To collect water from rainfall.
To collect water from rainfall.

I was born and raised in America, and this was Miami, where I live, but they weren't quite ready to let me in yet. "Please wait in here, Ms. Abujaber," the immigration officer said. My husband, with his very American last name, accompanied me. He was getting used to this. The same thing had happened recently in Canada when I'd flown to Montreal to speak at a book event. That time they held me for 45 minutes. Today we were returning from a literary festival in Jamaica, and I was shocked that I was being sent "in back" once again. The officer behind the counter called me up and said, "Miss, your name looks like the name of someone who's on our wanted list. We're going to have to check you out with Washington." "How long will it take?" "Hard to say...a few minutes," he said, "We'll call you when we're ready for you." After an hour, Washington still hadn't decided anything about me. "Isn't this computerized?" I asked at the counter, "Can't you just look me up?" "Just a few more minutes," they assured me. After an hour and a half, I pulled my cell phone out to call the friends I was supposed to meet that evening. An officer rushed over. "No phones!" he said, "For all we know you could be calling a terrorist cell and giving them information." "I'm just a university professor," I said. My voice came out in a squeak. "Of course you are. And we take people like you out of here in leg irons every day." I put my phone away. My husband and I were getting hungry and tired. Whole families had been brought into the waiting room, and the place was packed with excitable children, exhausted parents, and even a flight attendant. I wanted to scream, to jump on a chair and shout: "I'm an American citizen; a novelist; I probably teach English literature to your children." After two hours in detention , I was approached by one of the officers. "You're free to go," he said. No explanation or apologies. For a moment, neither of us moved. We were still...
