Höganäs AB, a major Swedish specialist in powdered and sintered metals, has created a bicycle motor as a low cost, light weight, high performance unit for the Asian market. According to Höganäs Group CEO Alrik Danielson, “We chose the bicycle motor as a first application when introducing our new motor concept. The bicycle motor is very challenging, in terms of performance as well as cost, but we are confident that we have a unique product. It is lighter than other electric motors and in the e-bike it has a good range, up to 75 kilometres, thanks to high efficiency.” He sees the modular design as being adaptable to other applications, such as “scooters, other light weight electric vehicles, pumps, fans …

Green Flight Challenge Competitors Come Together on Perlan Project

Dean Sigler GFC 1 Comment

The Cafe Foundation’s Green Flight Challenge, scheduled for 2011, has drawn some impressive competitors with its $1.5 million prize.  Two of these, Greg Cole of Windward Performance, who will field a two-seat motorglider, and Einar Enevoldson, leader of the PC-Aero team, which will launch its Elektra One (see “PC-Aero’s Elektra One,” April 11, 2010), are working together quite collegially on a challenge of their own. Before his death in 2007, adventurer Steve Fossett, with co-pilot Enevoldson, had set the sailplane world altitude record in Perlan I, a modified Glaser-Dirks DG-500.  In a continuation of that ambitious adventure, Einar, Greg, and Project Manager Morgan Sandercock are creating Perlan II, a pressurized sailplane that will explore the realm of the nacreous, or …

Synergy and Passion at EAS

Dean Sigler Electric Powerplants, Feedback, Sustainable Aviation 0 Comments

John Palmerlee, Editor of The Flying Wire, Experimental Aircraft Association Chapter 124’s newsletter, wote this in the May 5, 2010 edition.   The CAFE Team hosted what was in my opinion a very successful event at the Doubletree Hotel in Rohnert Park, April 23 and 24, 2010. Nearly thirty contributors from around the world spoke at the Electric Aircraft Symposium, and their message was clear: Change is coming… let’s get on board together. Electric airplanes and motorcycles, model airplanes, algae biofuel synthesis, wetlands initiatives, hybrid air carriers, battery breakthroughs, VTOL PAVs, tethered wind generators, flight systems analysis, nanostructures… and a mystery Green Flight Challenge aircraft promising to tap into new design paradigms. This was just a taste of the concepts …

The Battery Pack Builder with the Ceramic Wedding Ring

Dean Sigler Electric Powerplants 1 Comment

The Killacycle Racing Team is led by two people, Bill Dube’, designer, builder, and driver of the world’s fastest electric motorcycle, and his wife, Eva Hakansson, crew chief and battery builder for the high-velocity two-wheeler.  Eva’s talk at the fourth Annual Electric Aircraft Symposium in Rohnert Park, California caused several stirs in the audience, and hinted at where battery technology might go in the future. Wanting to free electric vehicles from their “boring and slow” image, Eva seeks to make them “sexy and fast.” Pictures of her and Bill’s wedding, in which the bride wore traditional Swedish wedding garb and entered on a motorcycle, the ceremony took place in a motorcycle trailer, and for which both bride and groom wore …

Bagging Algae – Pollutants into Energy

Dean Sigler Sustainable Aviation 1 Comment

For the Fourth Annual Electric Aircraft Symposium on April 23 and 24 in Rohnert Park, California, Dr. Jonathan Trent was an ideal kickoff speaker. His work with NASA Ames Research Center on converting pollutants into algae-based biofuels could have long-term effects on cleaning up our planet’s air and water, and provide byproducts that will help to feed the 900,000,000 who go hungry every day.  As he notes, “Unless we go electric, we must move to low-carbon fuels.” The problem is not a new one.  As musical satirist Tom Lehrer wrote in his 1960’s plea for emissions control, “Pollution, Pollution,” “The breakfast garbage that you throw in to the bay/They drink as lunch in San José.” Dr. Trent, a PhD. in Marine …

Summer Flights for Electraflyer X

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

According to AVweb.com, Randall Fisher of Electraflyer had his two-seat Electraflyer X on view all week at Sun ‘n Fun in the Greenspace display area, devoted to environmental consciousness and green products.  Fishman flew the single-seat Electraflyer C – a modified Moni ultralight – daily, and a team member flew the company’s electric trike regularly.  Most exciting, Fishman is projecting motor testing and test flights of the X this summer, with series production of a kit version to follow, and release of a light sport aircraft, factory-built version as soon as permission can be granted by the FAA.  From earlier discussions with Fishman, this airplane should be competitive in performance and cost with the Yuneec E-430. As icing on the cake, …

FES at Friedrichshafen

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

The Front Electric Sustainer motor system, developed by Slovenian father and son entrepreneur team Matija and Luka Znidarsic, was on display at the E-Flight Expo, part of the larger Friedrichshafen Aero 2010 show.  Both are graduates in Mechanical Engineering from the University of Ljubljana.   This system, described in an earlier entry (“Power Up Front,” November 1, 2009), is meant to provide power for a sailplane that is launched by other means, such as an aerotow or winch.  Its light weight does not detract from the normal performance of the sailplane, but does enhance safety, with the pilot able to start the motor and power away into a modest climb if necessary to save a flight. In response to this editor’s naive questions, Luka responded, “No, there …

PC-Aero’s Elektra One

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 14 Comments

Dipl. Ing. Calin Gologan, an exhibitor and presenter at this year’s E-Flight Expo at Friedrichshafen, will be at the fourth annual Electric Aircraft Symposium, discussing the design and technology he hopes will imbue the winning entry in next year’s Green Flight Challenge.   He notes that the GFC, “the world’s largest prize…awarded in general aviation,” was a major incentive in his pressing forward with an environmentally conscientious design. His Elektra One is part his PC-Aero’s ambitious campaign to fly three different electric aircraft in the next few years, the single-seat “One,” two-seat “Two,”, and most ambitiously, a four-seat “Four.” With at least the shell of Elektra One at the Expo, Gologan is making good progress toward completion of his GFC machine, the prototype for …

Gérard Thevenot Wins E-Flight Award at AERO 2010

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

With over 30 electrical flight exhibitors at Friedrichshafen, Germany’s Aero 2010 International Exposition for General Aviation, selection of this year’s E-Flight Award winner must have been particularly difficult. The”E”of the E-Flight portion of the huge show represents, “Electrical, Ecological and Evolutionary.” Thevenot’s machine is all those. Gérard Thevenot flew his hydrogen-powered ultralight “trike” across the English Channel in July, 2009 (“Man of La Manche”, October 29, 2009), with a Geiger/Eck HP-10 electric motor powered by a hydrogen fuel cell, “without the onboard presence of an accumulator or battery.” Showing his 55 kilogram (121 pounds), seven kilowatt (11 horsepower), 12 meter (37 feet) span ultralight at last year’s Expo, he went on to demonstrate its capabilities in the following months. Its …
