The spectre of fuel- and pollution-free air travel drew closer this month as the first airplane powered completely by solar energy completed its first intercontinental flight. The Solar Impulse left Madrid, Spain in the early morning hours of Tuesday, June 5 and flew across the Strait of Gibraltar to Rabat, Morocco, where it made a spectacular landing 19 hours later. The plane has the wingspan of a jumbo jet, but weighs only as much as a medium-size car. In 2010, the Solar Impulse earned a place in history after it became the first airplane to fly for more than 24 hours straight using only solar energy. The aircraft stayed aloft for 26 hours, 10 minutes and 19 seconds, and also set a record for altitude, having flown at an elevation of 30,298 feet. Technology now allows the solar-powered plane to fly both day and night. The landing in Morocco’s capitol of Rabat was also symbolic for another reason: that country’s progress toward development of viable amounts of renewable, non-polluting energy. This year Morocco will award a contract to build a power facility that will generate 160 megawatts of solar power — the first step in an ambitious and progressive national plan to generate 38 percent of the country’s electricity from solar power by 2020. The goal of the Solar Impulse Project is to prove that progress is possible using clean forms of energy, and that it is possible to eventually free societies from dependence on fossil fuels.
