Sunseeker Duo, Dynamic Duo Do the Alps

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Irena Raymond shared the following about her and huband Eric’s flight across the Alps from northern Italy to Switzerland and return – a four-day tour of the mountainous country, and validation of the Sunseeker Duo’s performance. The latest of a series of accomplishments, the trip’s mission was to “stop and show the airplane at different airports,” according to Irena. Remember that Eric crossed the United States on solar power in Sunseeker I in 1990, 23 years before Solar Impulse managed the feat. Eric crossed the Alps on his way from Friedrichshafen, Germany to the World Air Games in 2009, guiding Sunseeker II over sometimes cloud-shadowed peaks. Now he and Irena have made a two-person Alps crossing and tour of the …

Sunseeker Duo Goes Dual

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

Irena Raymond became the first passenger of a solar-powered airplane recently, even taking over control of the Sunseeker Duo she and husband Eric built over the last several years.  Her thoughts provoke awe and envy. “Flying the Duo, skimming the white fluffy clouds from above and playing on the sky, I feel like a bird. No limitations, a pure freedom. It’s so quiet! Compared to a normal airplane, it’s like night and day. You need a very good headset in every other powered airplane, but in this airplane you can speak normally even when the motor is running full power, no headset needed. It is unbelievable.” Eric provides some hard data to complement Irena’s understandably poetic words.  “I am expanding the …

Sunseeker Duo Makes Test Flights from December 17 to Earth Day

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

Eric Raymond announced today that his Sunseeker Duo, the world’s first solar-powered two-seat aircraft, has been making test flights since last December 17, the 111th anniversary of the Wright Brothers’ first flight. The Duo was built by Eric and his wife Irena, and is Eric’s third solar-powered airplane.  His first, Sunseeker I, flew across the United States in 1990, making 21 hops from San Diego, California to Kitty Hawk, North Carolina.  Sunseeker II flew from Friedrichshafen, Germany across the Alps to Italy, then toured around Europe. In Eric’s announcement today, he claims that, “The Duo is the most advanced solar powered airplane in the world and the first that might be suited to production. It is also the first solar …

Sunseeker Duo Shows Completed Form at Friedrichshafen, Moves to Italy

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Erik Raymond is moving his shop and Sunseeker Duo project to Voghera, Italy, nestled in Northern Italy between Milan and Genoa.  He showed the completed airframe at this year’s Aero Expo at Friedrichshafen, Germany and discussed, no doubt, the future of electric aviation with Axel Lange, the CEO of Lange Aviation.  Lange has developed the Antares and Arcus electric motorgliders, both outstanding designs. Following the Expo’s finale, Erik and his wife Irena drove south to Italy, where their enterprise will complete work on the Duo and plan for their proposed trips in unexplored realms– all on solar power. With Solar Impulse crossing the United States (which Erik did in 1990 in Sunseeker I) and more flights planned by other participants, …

Floating Over the Danube: The Vision of the Little Tailor of Ulm Lives

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

The beautiful blue Danube River of Strauss waltz fame, “…Rises in the Black Forest mountains of western Germany and flows for some 1,770 miles (2,850 kilometers) to its mouth on the Black Sea. Along its course, it passes through nine countries: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Romania, and Ukraine,” according to the Encyclopedia Britannica. In 1811, Albrecht Ludwig Berblinger, a tailor in the city of Ulm near the headwaters of the second longest river in Europe, tried a novel idea – flying across the river on a nicely sewn-together hang glider.  His splashdown marked the end of his aeronautical career, but made him famous and an unlikely harbinger of things to come. City fathers have announced, “In the spirit of Berblinger, and continuing his vision, the City of Ulm aims to promote …

Solar Flight on a Winter Wave

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Eric Raymond sent the following today. “Had a nice SUNSEEKER flight today, 3 hours, and as usual I could have stayed up into the dark, even in January!  This time there was wave lift, but very weak, despite 30 knot winds at 6700 meters (21,500 feet). “In the pictures you can see the inversion clearly, and the Adriatic covered in a blanket of clouds. “My batteries are very old and cold, but I still got high enough to connect with the wave, which went on forever. “Taxing was tricky because of big lumps of snow, so I landed downwind, as the taxiway is not cleared. Both his Solar Flight website News and Blog show more, including the construction of the Sunseeker …

Your Chance to Help Kickstart an Historic Airplane

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Kickstarter, an online crowd funding platform, helped John McGinnis work toward the completion of his ambitious and aerodynamically advanced Synergy.  Another innovator and pioneer in solar-powered aviation has enlisted the aid of Kickstarter for a superb project and a great adventure. Eric Raymond flew across the United States in 21 solar-charged hops in 1990, making a trek from San Diego, California to Kitty Hawk, North Carolina, navigating and soaring with his Sunseeker. Nearly two decades later, he took Sunseeker II from Germany to Italy, conquering the Alps and fulfilling a life-long dream to top the Matterhorn. Since then, he’s also flown the University of Stuttgart’s e-Genius to second place in the Green Flight Challenge last September, co-piloting with Klaus Ohlmann, another …

Solar Impulse Inspires in Brussels, Heads to Paris

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

On June 14, 2011, Andre’ Borschberg guided the giant Solar Impulse from Brussels, Belgium, where the craft had spent the last week as the centerpiece of discussions on green energy and the future of transportation in the European Community, to Le Bourget Field just outside Paris.  Nearing its destination, its daylong flight sometimes resembled the mathematical problem called, “the drunkard’s walk,” as Borschberg was vectored around the aerial neighborhoods surrounding Paris to make certain the lightly loaded craft did not run afoul of  jetliners’ wakes and could find a slot where the runway did not present residual turbulence.  During the preceding week, VIPs from the European Community gathered aound the airplane in Brussels to discuss the importance of this airplane and …

Ingenious e-Genius

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

At the third annual Electric Aircraft Symposium in San Carlos, California in 2009, designers from Germany and Slovenia showed their plan for a hydrogen-powered aircraft called Hydrogenius.  Today, a newly constructed, battery-powered “e-Genius” (developed along parallel lines with Hydrogenius) will be Eric Raymond’s mount for the July 10-17 Green Flight Challenge in Santa Rosa, California.  Eric writes that “e-Genius is now flying, and has reached the required 100 mph.” Hydrogenius’s original layout, replaced for the Green Flight Challenge with a simpler lithium-polymer battery-only system.  1 – Hydrogen tank 2 – Radiator 3 – Stack Module (Hydrogen Fuel Cell) 4 – System Module (Hydrogen Fuel Cell) 5 – Power Distribution Unit 6 – LiPoly Battery to start the fuel cell system 7 – …
