Stephen Boutenko, founder of Alternair, LLC and Karl Young, founder of Extreme Capacitors have found common cause in analyzing how best to make an electric Light Sport Aircraft (LSA) a possibility.   Alternair’s Amp LSA was featured in a blog entry last year, and Karl Young’s work with ultracapacitors was the subject of his presentation at this year’s Electric Aircraft Symposium. Alternair has recently established a temporary design department in Prescott, Arizona (in association with Embry Riddle Aeronautical University) and is moving his manufacturing facility to Ashland, Oregon, where he hopes to begin production of the highly-sophisticated Amp. Although Amp will be developed around existing lithium-polymer battery technology, Young reports that his creation of high power/high energy ultracapacitors has demonstrated, …

But capacitors.”  Karl Young, CEO of eXtreme Capacitor, Inc. started his presentation at the fifth annual Electric Aircraft Symposium with these words from Tesla Motor’s Elon Musk.  The reference to capacitors superseding batteries as an energy source for electric cars came from Musk’s address at the Cleantech Forum in San Francisco on 16 March 2011. Young’s talk before the April 29 gathering in Santa Rosa, California detailed the double-layer supercapacitors his company produces, and what Young feels are the advantages these have over “traditional” lithium and other batteries.  He is “trying to overcome the issues of batteries,” including, according to Young, their …
