Solar Impulse: Last Trip from Washington, D.C., to New York

            The ultimate goal for Solar Impulse was to fly across the globe powered solely upon the sun's rays. So far, it has accomplished many goals in the last three years: in 2010, it flew for 26 hours straight; in 2011, it flew from Belgium to Paris, France and in 2012, a prototype had completed the first intercontinental flight connecting from Europe to Africa. This year, it proposed a challenge to fly across United States from the East coast to the West. 

The itinerary featured: from San Francisco (California) to Phoenix (Arizona) to Dallas (Texas) to St. Louis (Missouri) ending in the last haul to Washington, D.C., and New York

The fourth leg from St. Louis to Washington, D.C., has been completed successfully while the trip from Washington D.C., to New York is steadily approaching. You can view updates and the schedule for the rest of the historic flight here.

There are also many videos of their stops featured here.

Recreation: Building a Solar-Powered Plane

       For those arts and crafts fans, get ready to take a new level by building your very own solar-powered plane. Instructables user jeffmazter406 have provided a step-by-step guide, along with detailed instructions and photos, in creating one, which is a similar yet mini version of the Solar Impulse plane. It also links to two Powerpoint presentations by Texas A&M University to help walk you through the procedures.
     

         This project has been constructed by Newman Smith High School students with the help of faculty in Carrollton, Texas and has been sponsored by the Texas A&M University Society of Flight Test Engineers. The team, in addition, notes that "the project is not for the beginner as it gets complicated." However, if you may feel the need to want to experience and create a solar-powered plane, click here. 

The World's First Solar-Powered Helicopter Takes Flight

      As projects like the Solar Impulse and NASA's Helios wing has been recently developed, the idea of propelling aircraft using solar power isn't as fanciful or impossible to accomplish as it seemed before, even if they are still in experimental stages. Before long, we'll surely be able to see solar power used to aid traditional airplanes, even if it is not accompanied by main fuel.
     To show what is possible, a team of master students from the United Kingdom have built what they believe to be called the world's first "solar-copter," a quadrotor that flies solely on solar power. At the moment, it is capable only of short flights but the team had claimed that it should fly longer soon, once they enabled it to have a storage system as well.

     "The Solar-copter is a quadrotor design that incorporates a solar panel providing the power for the propulsion system," the six students had commented. "It is controlled in the same way as a standard battery-powered quadrotor. Optimum thrust-to-weight ratio was mainly achieved through an efficient propulsion system, unique frame design and an optimized solar panel."

     Future versions may be useful in activities such as surveillance, search and rescue, and tracking animal migrations, perhaps in Africa, Australia, Middle East, and Southern Europe, where there is more sun than in England. Its technology could also help increase the range of conventional choppers, and perhaps give other solar aircraft, such as the Solar Impulse, better maneuverability and control.

Solar-Powered Plane's Cross-Country Flight

        Researchers at Moffett Air Field at NASA Ames Research Center in Mountain View, California, announced on March 28 that Solar Impulse, an ultra-lightweight plane solely powered by solar power, is planned to fly coast-to-coast this spring. The plane is claimed to require no fuel and solely rely on solar panels and battery power.
        Two Swiss pilots of the Solar Impulse, Bertrand Piccard and Andre Borschberg, desire to complete a flight beginning from Moffett Field to New York City. Along the way, it is planned to stop by in the following locations: Phoenix, Arizona, Dallas-Ft. Worth, Washington, D.C., and either Nashville, Tennessee, Atlanta, Georgia, or St. Louis. The plane is set to fly on May 1 and plans to land in the Big Apple in early July.
         Solar Impulse has a wingspan equivalent to a 747 jetliner, the weight of a station wagon, and the power needs of a small scooter. The solar panels across its wings harness power from the sun during the day, and lithium-polymer batteries store that energy for overnight trips. A carbon-fiber material formed in a honeycomb structure makes up the bulk of the plane, which allows for its feather-weight.
        In 2010, the plane completed a 26 overnight-hour flight and in 2012, it flew from Switzerland to Morocco with no fuel.
