It’s not faster than a speeding bullet. Nor is it more powerful than a locomotive. In fact, flying at about 45 miles per hour, the solar-powered aircraft known as Solar Impulse isn’t the quickest way to fly, but it may be the most eco-friendly.
And it’s left some people scratching their heads. “It’s a bird… it’s a plane, it’s…?” Last month, as Solar Impulse flew from Dallas to Phoenix, the local 911 call center received dozens of reports of UFO sightings thanks to the unusual aircraft that appeared to hover on the desert horizon. But it’s not alien technology – it’s solar – and that’s exactly the point. Alternative energy is available today, and Solar Impulse is an excellent showcase for the innovation that makes it possible, including advanced coatings, films and adhesives.
