Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

Appearing before attendees at the 2013 Electric Aircraft Symposium, Randall Fishman’s spoke of great accomplishments and grander visions.  “ElectraFlyer ULS & Electric Ultralight Airplanes, the path to approval for all electric aircraft?” showed ElectraFlyer’s history and the ambitions Randall would like to play out. A pioneer in ultralights, Randall has been flying hang gliders since 1972, produced the first continuously powered electric aircraft, flew the first electric airplane at Oshkosh’s AirVenture and claims a primary interest of bringing practical, user-friendly electric flight to as many people as possible. Between 2005 and 2007, he designed, built and test flew his first electrically-powered trike.  Making its first take-off on April 29, 2007, by May 2 it had made a one-hour flight.  Ever …

On March 28, Pipistrel rolled out its prototype Panthera, a sleek four-seat cruiser destined to be the first production hybrid aircraft and eventually, Pipistrel’s second four-seat electric airplane. It is currently powered by a Lycoming IO-390, 210 horsepower engine.  At Pipistrel’s factory in Ajdovscina, Slovenia a team of engineers and technicians fired up the engine for the first time and performed ground runs, “verifying design parameters and engine operation.” Pipistrel’s press release quotes Ivo Boscarol, their CEO: “It is very exciting to witness the tests and see the aeroplane come to life for the very first time. This is definitely a very important milestone in the development of Panthera. We look forward to the continuation of tests and the first …

What Do You Have on Your DVD Burner?

Richard Kaner and Maher El-Kady have “micro-scale graphene-based supercapacitors” on their front DVD burner, showing an energetic alternative to saving all those ‘80’s rockers to disc. Dr. Kaner is a member of the California NanoSystems Institute at the University of California at Los Angeles (UCLA) and professor of chemistry and biochemistry.  He and graduate student El-Kady are using a “consumer grade” LightScribe DVD burner to make dozens of micro supercapacitors on what looks like a typical DVD. Dr. Kaner’s research lab hosts 17 undergraduate and graduate student researchers who’ve helped amass at least 390 papers in four main areas of research; conducting polymers, graphene, superhard materials and thermoelectric materials.  Their recent investigation of supercapacitor fabrication seems to encompass almost all …
