Combine the Joby S4 pre-production prototype with H2 Fly’s expertise in providing clean energy, and watch world records fall. 2021 155-Mile Battery Flight Justin Paines, Joby’s Chief Test Pilot, guided the eVTOL through eleven circuits of a pre-designated route and managed 154.6 miles (248.8 km) in just 77 minutes. JoeBen Bevirt, Joby’s founder, noted his firm had, “achieved something that many thought impossible with today’s battery technology.”  Batteries have improved since then, but an alliance with a German hydrogen program makes even longer flights possible. 2024’s Hydrogen Odyssey In an even greater demonstration of its capabilities, an S4 powered by hydrogen managed a 523 mile, non-stop flight on June 24, 2024.  Powering around a circuit above Marina, California, the craft landed with 10 percent of its 40-kilogram (88 pound) hydrogen load still available. A collaboration between Joby and Germany’s H2-Fly uses much of the same system as H2-Fly’s Hy4 aircraft, a re-engineering of the G4 designed by Tine Tomažič, head …

First Flight of Rolls-Royce’s ACCEL Project

Rolls-Royce has made a first test flight of its ACCEL Program’s “Spirit of Innovation,” their 400 kilowatt (500+ horsepower) electric record-seeking craft.  Powered by a stack of three YASA (Yokeless And Segmented Armature) motors, the Spirit flows from Jon Sharp’s NXT design, usually powered by a 540-cubic-inch internal-combustion engine.  The video includes a short nod to Rolls-Royce’s involvement in aviation that leads to the current project. Rolls announced the successful first flight with an important accomplishment and a hopeful prediction.  “We are pleased to announce the completion of the first flight of our all-electric ‘Spirit of Innovation’ aircraft. At 14:56 (BST) the plane took to the skies propelled by its powerful 400kW electric powertrain with the most power-dense battery pack ever assembled for an aircraft. This is another step towards the plane’s world-record attempt and another milestone on the aviation industry’s journey towards decarburization.” The flight, made on the 81st anniversary of the Battle of Britain day, acknowledged as the …

Greeting the New Year with Hope

Two Videos to Ponder We’re not there yet, in the land of flying cars and even motorcycles.  But we do have some pretty good images of where we are and where we might be headed.   CNBC produced some pretty thoughtful and well-researched pieces on a major problem plaguing all of us who live within bumper distance of one another – and some plausible solutions.  Both videos touch on urban air mobility. How Much Do Traffic Jams Cost the U. S. Economy? Gridlock, traffic jams and delay – they all frustrate us daily if we live in a big city.  They take away from family time, pollute the air, and drive us to distraction.  This video ends with an optimistic take on the benefits sky taxis might bring to groundlings everywhere.  We could use cleaner skies, more time at home, and more Zen-like minds.  You might learn how to handle the challenges of heavy traffic, too. Why Don’t We Have Electric …

Sustainable Aviation Symposium 2019

Dean Sigler Announcements, SAS, Sustainable Aviation Leave a Comment

The 2019 Sustainable Aviation Symposium is moving to a new date and location – and a new inclusiveness. The University of California, Berkeley Institute for Transportation Studies (ITS) will host the 2019 Sustainable Aviation Symposium (SAS) on October 7-8 of 2019.  SAS 2019 is focused on safe, quiet, electric aviation solutions to the most pressing problems of our age: climate change, urban surface gridlock, and the need for integrated community and urban planning to enable high proximity aviation at meaningful scale. Dr. Jasenka Rakas, founder and head of the Airport Design Studio at the University of California at Berkeley, and Sustainable Aviation Foundation founder and President Dr. Brien Seeley will co-chair the meeting that will present a challenging review of aviation’s green future. This year’s symposium will convene thought leaders to answer these core questions: Which systems will win a dominant share of the market and why? How will “urban air vehicles” be made “airline-safe” and autonomous? What new technologies are …
