Powering Imagination, a symposium devoted to that premise and to encouraging the development of electric aviation, achieved both goals on Saturday, February 28 at Seattle’s Museum of Flight. Organized by Erik Lindbergh and Eric Bartsch, the gathering included two panel discussions and eight presentations that helped define where the world of electric flight might be heading. Between 10:00 a.m. and 5:00 p.m., presenters covered a lot of ground. Following Cale Wilcox, the Public Programs Coordinator for the Museum’s, introduction, Erik Lindbergh took the stage to explain the goals of the Powering Imagination organization, including making aviation clean, quiet, exciting and affordable. This democratization of flight mirrors aspirations of the CAFE Foundation and is reflected in the educational efforts made by Lindbergh’s organization. He explained that the X-Prize helped jump start private space flight, then asked how we translate that interest into helping form an electric aircraft industry. Development of this new industry may be crucial to aviation’s survival, with its …

A Cheerfully Acknowledged Chastisement
If one writes things, occasional slip-ups creep in. In this case, an unchallenged assertion of who is “first” drew this kind email from Klaus Savier, builder, tuner and pilot of a very slippery Long-Eze. He’s flown from California to Florida and back on good old fossil fuels (with one fuel stop each way) in his highly modified Long-Eze and achieved 30 miles per gallon at 250 miles per hour true airspeed. It would be interesting to see how little fuel the airplane would consume at Green Flight Challenge airspeeds. His demonstrated 0.36 pounds of fuel per horsepower-hour is claimed by Klaus to be 40-percent lower than the commonly seen 0.60 pounds per horsepower-hour that engines without his Light Speed Engineering ignition system and more standard propellers manage. It shows what a determined experimenter can accomplish. His letter follows: Hello Dean, Thank you for the nice article you wrote in Kitplanes a while ago. So far that was the only publication …
It’s (Green Aviation) Giving Tuesday, 2014
If you’ve managed to survive Gray Thursday, Black Friday, and a weekend of NFL games stuffed with blandishments to entice you to the nearest mall (Thanksgiving happened in there somewhere), you’re forgiven if you flinch at yet one more presumptuous tug at your purse strings. But we’re talking about helping pioneers on the edge of green technology, crafting the stuff dreams are made of – and making those dreams a reality. On this Giving Thursday, think about contributing to the dream makers who are taking us into a better future of flight. We share a few suggestions here. Solar Flight Eric and Irena Raymond are the first family of solar-powered flight, now cruising Italian skies in the world’s first two-seat sun-powered airplane, the Duo. To assist with further development of their splendid aircraft, including Sunstar, a high-altitude surveillance and communications craft, the couple is selling a beautiful calendar featuring their aircraft. For $37 US or 29 euros plus shipping, you …
e-Genius, Klaus Ohlmann Set Records, Records, Records!
“Records, Records, Records!” heads the news on the Institut for Flugzeugbau (IFB) web site this morning. The sub-head reads, “Experienced hands plus a high-performance airplane plus one week equals seven world records.” Admitting to fuzzy math, the writer still draws a clear line to the seven records. Klaus and e-Genius spent the third week of July in Seeres – La Bâtie, France where they achieved seven FAI (Fédération Aéronautique International) World Records in the Category of Electric Airplanes. According to the IFB, “In two flights (July 18th and 19th) he attained: – Speed on a 100 km round trip : 178.1 kilometers per hour (96 knots, or 110.4 mph) – Speed on a 500 km round trip : 93.03 km/h (50 kt – 57.5 mph) – Distance of 504 km (312 miles) – Absolute altitude of 6,376 m MSL (20,918 feet) – Time to climb to 6,000 m (20,000ft) : 1:53 min (an average of about 177 feet per minute) …
Where Are They Now? The Electric Phoenix
MGM COMPRO, a Czechoslovakian motor and electronics supplier, announced that they had participated in finally making the Phoenix motorglider an electric machine. Jim Lee and co-pilot Jeff Shingleton had originally intended to fly the airplane at the Green Flight Challenge three years ago, but contented themselves with competing in the Rotax-powered machine and “only” winning third place in the event. Their competing did elicit a great deal of interest in the machine, though. MGM says, “We are very glad that we can present you a very successful project, [the] U-15 Phoenix of the Czech entrepreneur Martin Stepanek. MGM COMPRO plays a decisive role in a development of industrial controllers for this fully electric aircraft. As described in the blog three years ago, the electric PhoEnix is a “nice airplane,” and one that would take many willing pilots on many cross-country jaunts. Martin originally planned to use a Czech industrial motor for power, but ended up developing his own powerplant that …
Batteries, Fuel Cells – or Something Else?
We’re coming to a parting of the ways in energy storage development for electric cars. Or we may be coming to a joining of technologies in new and previously unimagined ways. One side, led by Elon Musk and his Tesla Empire, promotes battery power and development. Yet, in Tesla’s home state of California, government and private investments in hydrogen vehicles is growing. Several Asian and European automakers are bringing out fuel cell powered vehicles in the face of low numbers of existing fueling stations. For all the promotion from either side, future “green” cars may become too expensive for private ownership, and various approaches to providing personal mobility may replace the traditional owner-driver model. Regardless of the outcomes or market shares, the technology will be applicable to personal aviation, although perhaps at a significant price. Battery-Powered Vehicles Lead – For Now According to EV World, “In the last year, global registrations of electric vehicles from the first three years of …

He pointed out that the first “A” in NASA stands for “Aeronautics,” the agency’s first major area of research and policy making. Dr. Shin noted that the Wrights brought us powered, controlled …
The Green Speed Cup – Fourth Edition
Robert Adam helps run the Green Speed Cup, a time, speed and economy run for aircraft in Germany. The rules for this year’s contest elucidate the intent and ambitions for the event: “The GREEN SPEED CUP is an aviation competition focusing on efficient flight. The emphasis lies on fast and energy saving transportation. The competition is meant to develop new methods to reduce energy consumption of motor driven aircraft using external energy sources like lateral winds and updrafts. In making the ability of certain aircraft and techniques transparent, the competition shall set new standards in general aviation.” The Cup provides a sounding board for discussion of energy efficient flight and the changing experience of flying while exploring new techniques and technologies. Hosted by STEMME Aviators e.V., the contest is open to “all aircraft capable of taking off under their own power,” with the following restrictions: In the Electric Class, airplanes may have one to four seats, weigh up to 2,700 …
EAS VIII: Bruno Mombrinie and Dr. Brien Seeley – Economies and Practical Considerations for Sky Taxis
Bruno Mombrinie, a director for the CAFE Foundation, and Dr. Brien Seeley, founder and President of the organization, gave a one-two presentation on pocket airports and Sky Taxis that examined the practical and operational facets of such a program, first described in detail in a joint NASA/CAFE Foundation document. According to Bruno’s CAFE biography, “As a freshman, he helped build MIT’s Chrysalis human powered airplane. Later that summer he got to fly the plane several times. ‘The feeling of being so, so high (39ft)…to fly under my own power was beyond…I just wanted to burst…actually I was so out of breath from the effort, I could hardly mouth ‘yippee!’” (The Chrysalis, and other MIT designs led to Daedalus, the HPA that flew from Crete to Sicily on April 23, 1988 – 72.44 miles in less than four hours.) This experience with extreme pedal power probably helped inspire his work on the Negative Mass two-piece crankset, reputedly the world’s lightest and stiffest bicycle crankset. His …
