Eric Raymond is a real pioneer in electric aviation.  Decades before Solar Impulse made its epic flights Eric navigated his solar-powered Sunseeker I across the United States in 21 hops, traveling from Desert Center, California to Kitty Hawk, North Carolina. He flew over the Matterhorn on his way from Germany to Italy in Sunseeker II.  He and his wife Irena build the world’s first two-seat solar-powered airplane, the Duo, which they regularly fly over Italy and Switzerland.  He shared the promise and mystique of such flight with the readers of Travel Forward recently.   The Future is Electric: Exploring the World in a Two Seat Solar Powered Airplane MAY 18, 2020 BY TRAVEL FORWARD While Tesla and other car manufacturers are …

Boxing Day is a holiday unique to the British Empire, a day-after Christmas gift-giving celebration in which the well-off gave gifts to their servants. Yahoo Entertainment explains, “While there is some dispute over what the name actually means, it’s commonly believed that Boxing Day refers to the habit of aristocratic employees gifting their servants or tradesman on Dec. 26 as a thank you for their work throughout the year. The employers would give them each a box to take home to their family with gifts, bonuses and leftover food. “Samuel Pepys, a naval administrator and Member of Parliament, is famous for writing in his diary in 1663: ‘Thence by coach to my shoemaker’s and paid all there, and gave something …

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 …

Many Happy Hours in Sunny Skies

Eric Raymond, over the last 20 years, has accumulated more solar-powered flying hours than any other pilot. And what hours these have been. Having met Gunther Rochelt and flown Rochelt’s Musculair human-powered airplane in 1986, Eric was inspired to apply the light construction techniques to the building of a solar-powered airplane. In 1990, he flew Sunseeker I across the United State in 21 hops totaling 121 hours in the air, going from California to Kitty Hawk, North Carolina, the birthplace of powered flight. He upgraded Sunseeker over the years, improving the powerplant and aerodynamics of the amazingly light aircraft. Even with solar cells, batteries, and a 2.5 kW motor, the airplane weighed little more than a legal ultralight. Sunseeker II …
