The CAFE Foundation in its Electric Aircraft Symposia has put forth the idea of the 10X battery for many years. Dr. Seeley therefore found a great deal of excitement in the following news. Researchers at Northwestern University in Evanston, Illinois have perhaps achieved part of that dream, with a graphene and silicon anode that yields a 10-times-faster charge and can hold a charge 10 times greater than that of a typical lithium-ion battery. Claiming their technology will be on the market in three to five years, the researchers have published a paper describing the research in the journal Advanced Energy Materials. A University press release explains. “’We have found a way to extend a new lithium-ion battery’s charge life by 10 times,’ said Harold H. Kung, lead author of the paper. ‘Even after 150 charges, which would be one year or more of operation, the battery is still five times more effective than lithium-ion batteries on the market today.’ (Meaning …
Green Flight Challenge Winners
Monday, October 3 was the second day of Nobel Prize announcements, but also marked the Green Flight Challenge Expo, sponsored by Google and staged under the control tower on Moffett Field, home of NASA Ames Research Center, Mountain View, California. The four airplanes that flew in the Challenge at Charles M. Schulz Sonoma Country Airport in Santa Rosa, California were joined by Greg Stevenson’s full-size mockup of his GFC design and a Pipistrel Virus that had won an earlier NASA/CAFE Personal Air Vehicle (PAV) Challenge. Stevenson’s airplane was a reminder that there were numerous entrants that, for a variety of reasons, could not attend. There is a huge number of aircraft in the wings, so to speak, that will fill these pages in the next months and years. 20 exhibitors showed off their visions of a greener future, and three rows of tents protected exhibitors and their displays from the rain that started mid-afternoon. At about 11:00 a.m., attendees were bussed to Building …
Lucky 13 to Fly in Green Flight Challenge
Following rigorous evaluations of all aircraft to ensure they meet all standards for the contest, Dr. Brien Seeley, President of the CAFE Foundation, announced the 13 entrants who will compete in the Green Flight Challenge at Santa Rosa, California between July 11 and 17, 2011. This exciting event will offer the public a first view of some incredible designs and resourceful competitors. Since the minimum performance required for consideration includes things such as the ability to fly a 200 mile course at 100 mph or better average speed, the ability to clear a 50-foot barrier on a 2,000 foot runway during both takeoff and landing, and the efficiency to attain at least 200 passenger miles per gallon during the overall flight, all aircraft are obviously the most efficient aerial creations yet seen. Rules were established to encourage designers to make “real world”, practical craft rather than specialized designs that could win the contest but find no real purpose or willing owners. Even things such as cockpit design and …
Drs. Seeley and Moore Hit One Out of the Airpark
The January 2011 issue of Popular Mechanics resurrects the perennial hope for a flying automobile. The cover taunts, “(Go Ahead, Laugh) But NASA, DARPA & the FAA Are Serious.” Sharon Weinberger taunts some makers a bit in her article, “Driving on Air,” as she looks at a variety of Transformer-style vehicles that can travel by land or air with the fewest inconveniences. She notes the differences between propelling cars and planes, and looks at extremely different modes of giving people personal aerial transport, including the Moeller Skycar (“Inventor Paul Moeller has been developing the concept for nearly 50 years. To date, the M400X has only hovered on a tether.”), the Martin Jetpack, The Cartercopter, and the Terrafugia Transition that’s been getting an enormous press following (and a featured spot in the Hammacher Schlemmer Christmas catalog) lately. She ends with an overview of Dr. Mark Moore’s Puffin, detailed in this blog in January. After explaining that a commuter using the Puffin would rise …
CAFE News: NASA’s Colloquia Feature Dr. Seeley
col·lo·qui·um (n.) 1. An informal meeting for the exchange of views. 2. An academic seminar on a broad field of study, usually led by a different lecturer at each meeting. The Free Dictionary CAFE Foundation President Dr. Brien Seeley spoke by invitation at the Sigma Series Colloquium at NASA Langley in Hampton, Virginia on May 4th. His talk had an illustrious heritage as part of the longest-running science colloquia in America, beginning 50 years ago with a presentation by Werner von Braun, and since then including talks by Carl Sagan, Alex Haley, Neil Armstrong and other notables. Dr. Seeley was interviewed by NASA public relations TV and a local news station. Although not used to being treated like a celebrity, he found that, “People seem to think CAFE is latched on to an exciting future.” His talk focused on themes he has been developing for years – time wasted in traffic, the burden of maintaining the freeway/highway/urban sprawl infrastructure, the oil consumed …

CAFE Makes the Top of Kitplanes’ Cover
While at the local magazine store, or the proverbial fine book store, you’ll be able to spot Kitplanes’ August 2010 issue easily. The yellow letters on the cover line above the magazine title pop with upper-case intensity: “FUTURE SHOCK: CAFE’S Electric Aircraft Symposium.” Not only does the fourth annual Electric Aircraft Symposium get pride of place on the magazine’s cover and in four pages inside, but Marc Cook, editor-in-chief for the publication, titles his “Around the Patch” editorial “Making Electric Aircraft Exciting,” and proceeds to share his surprised discovery of respect for the new Toyota Prius, and to praise the husband-wife team of Bill Dube’ and Eva Hakansson, battery builder and racer, respectively, of Killacycle, the 0-60 in one second electric motorcycle. At a less-fevered pace, he predicts, “Gone will be the days that we fly at maximum continuous power in cruise….Maximum range comes at lower airspeeds and higher altitudes, one place the electric motor shines…. This will, in effect, turbocharge electric aircraft …
CAFE News: Doctors Seeley and Ford Stand and Deliver
At the fourth annual Electric Aircraft Symposium, April 23 and 24 at Rohnert Park, California, two CAFE leaders provided the audience with superb presentations on CAFE Foundation’s history and future goals. Dr. Larry Ford, Vice President of the organization, led with highlights from CAFE’s past, including the scientific efforts to measure aircraft drag and provide actual numbers for comparing aircraft performance, a goal inherent in the CAFE name. He highlighted the work of many past and present CAFE volunteers (after all, CAFE is all volunteer, and a 501c.3 charitable organization promoting aeronautical research at both the grass roots and the highest levels), including the CAFE Barograph, a significant instrument that allowed objective flight performance characterization of individual aircraft and honest comparisons between aircraft. Larry let audience members know about the contributions of Jack Norris, and his creation of “zero thrust glide testing.” This innovation involved finding the point at which the propeller was not creating drag or producing thrust. At …
Kitplanes Covers EAS IV
Kitplanes, and its on-line sister, AVweb, covered the fourth annual Electric Aircraft Symposium and generated a vido of the event, which includes a thoughtful interview with Dr. Brien Seeley, CAFE Foundation president. Expect to see more media coverage of CAFE Events as the Green Flight Challenge becomes a major aviation event in 2011.
The Future is Electric, and Attracting Attention
FlightGlobal.com, the online version of Flight International Magazine, has an overview of the electric aircraft scene in its April 6, 2010 release. Among the many producers and proponents of electric flight noted in the article, Dr. Brien Seeley of the CAFE Foundation is quoted extensively, as is Calin Gologan of PC-Aero in Germany, both to present at the fourth annual Electric Aircraft Symposium, at Rohnert Park, California on April 23 and 24. The article ponders the hopes of two hybrid electric aircraft powerplant developers, George Bye, featured in a February 21 entry in this blog, and Flight Design’s Oliver Reinhardt, the firm’s technical director. Both face the issue of retrofitting existing light planes with their new engines, and the challenge of obtaining supplemental type certification for such modifications. Highlighted is the 2011 Green Flight Challenge, in which an airplane achieving 200 seat miles per gallon at 100 mph (or an alternative energy equivalent mileage) can earn the CAFE Foundation’s $1.5 …
