Beta Technologies develops electric aircraft and a network of charging stations to support them. ALIA-250 – The A250 is an all-electric vertical take-off and landing aircraft that uses four top-mounted lift motors and one rear pusher motor to achieve vertical capabilities as well as wing-borne flight while in cruise.

Envisaged as all-electric , type, the planned flight range is approximately 110 miles (180 km), and almost twice that at 200 miles (320 km) as a ground vehicle. The Alef design utilizes hub motors for land travel, while for flight it incorporates eight motor-controller-propeller systems providing distributed electric propulsion , covered by a ...
Zunum Aero was founded in 2013 with Ashish Kumar as CEO and Matt Knapp as CTO. [2]Around the beginning of 2017 they launched plans to fly a prototype hybrid-electric airliner in 2019 or 2020, under the revamped FAR Part 23 rules for electric aircraft standards expected by 2018 and with first type certification by 2020.
The plane is to be sold as an experimental kit aircraft that requires only a private pilot license. [15] In October 2020 with a $60 million investment in Joby Aviation, a business building an electric vertical takeoff and landing (eVTOL) aircraft intended to provide air cab service, Delta joined the list of airlines funding EV technology startups.
It will be built with existing technology, including a composite airframe, propulsion from two Magnix electric engines [23] and Honeywell's flight control systems, including automatic landing. [8] At 3,700 kg (8,200 lb), the batteries account for 60% of the aircraft take-off weight. [12] Manufacturing is planned in the US. [11]
The use of EHD propulsion for lift was studied by American aircraft designer Major Alexander Prokofieff de Seversky in the 1950s and 1960s. He filed a patent for an "ionocraft" in 1959. [ 4 ] He built and flew a model VTOL ionocraft capable of sideways manoeuvring by varying the voltages applied in different areas, although the heavy power ...
Experimental regional aircraft retrofitted with fuel cell-electric propulsion systems have flown in 2023. In January 2023, ZeroAvia flew a Dornier 228 with one original Honeywell TPE 331 turboprop engine on the right wing and a proprietary ZeroAvia hydrogen-electric engine on the left wing. [ 49 ]
Electravia - Helices E-Props is a French aviation manufacturer based in Vaumeilh, specializing in the non-certified light aviation sector. [2] At one time it produced electric propulsion systems and now designs and manufactures carbon fibre propellers for light aircraft. [3]
