Sunseeker Duo – The Uniquely Big Picture

Unique People Eric Raymond was the first person to fly across the United States on solar power in 1990 in Sunseeker 1.  He was the first to fly on the sun’s rays over the Matterhorn in 2009 in Sunseeker 2. He and his wife Irena built the Sunseeker Duo and routinely fly it around northern Italy and over the Alps into Switzerland.  Eric has more hours piloting a solar-powered airplane than anyone, and Irena is probably the most experienced female solar pilot.  Only Bertrand Piccard and Andre’ Borschberg in the Solar Impulse would have anywhere need as much time at the controls.   Janice Brown, “a…former elementary school teacher” flew Paul MacCready’s Gossamer Penguin and Solar Challenger, even achieving a record altitude of 15,300 feet in 1981.  But Irena has by now easily exceeded Ms. Brown’s total solar flight time.   Eric and Irena are professional photographers, and all of Eric’s designs have sliding canopies or large openings to allow use …

Solar Flight SUNSTAR – a New High-Flyer

Eric Raymond has been designing and building solar-powered aircraft for 28 years, and flew Sunseeker 1 across the United State in 1990, Sunseeker 2 over the Alps in 2009, and has started touring Italy in the world’s first two-seat sun-powered aircraft, the Duo.  After three such outstanding efforts, what direction will his new design take? He took away any mystery on that today by unveiling his fourth aircraft, an optionally manned, high altitude platform, SUNSTAR.  Eric claims, “more performance potential than any of the other projects now under development. “Compared to other solar UAVs (unmanned aerial vehicles) being developed, the Sunstar promises higher flight speeds in a turbulence-tolerant design, for operation in real world conditions.” “Sunstar takes advantage of sailplane aerodynamic design philosophy to achieve the lowest possible power requirement to maintain flight at high altitudes.”  It takes technology tested on the Sunseeker Duo “to a whole new level.” Capable of unmanned flight for months at a time, the airplane …
