Ascendance Flight Technologies, a French firm developing an electric Vertical Take Off and Landing (eVTOL) aircraft, has doubled down on its original, smaller airplane.  Originally a four-seat, hybrid-powered machine with three lift fans, Atea has retained the name, but grown considerably. Holey Wings Atea now has eight lift fans and two horizontal propellers arranged in a push-pull configuration.  It can carry its five passenger in a “Skyview cabin” for 400 kilometers (248 miles)  Powered by its modular “Sterna” hybrid-electric propulsion system, the craft will hit as yet unspecified speeds, but within a two-hour range, that will probably be about 124 mph. An expansion of their original design, Atea comes from a group of former Airbus e-Fan engineers and technicians.  The …

Horizon Energy Systems (HES), originally based in Singapore, has pursued lightweight hydrogen propulsion systems for the last 12 years, primarily for amall drones.  Going larger, the company announced plans today for Element One, “the world’s first regional hydrogen-electric passenger aircraft.” A four-passenger, 14-motored (!) monoplane, Element One will carry the lucky foursome 500 to 5,000 kilometers (310 to 3,100 statute miles).  This distributed power system claims “virtually no change to its current drone-scale systems,” which is a little puzzling, considering the largest of such systems produces no more than 1,000 Watts.  The scale of the Element One and its power packs is ambiguous, with illustrations showing a nine-axle trailer with attached solar panels ostensibly powering the on-site production of H2. …
