The e-Genius follows a line of airplanes with alternative propulsion systems, which have been developed at the Institute of Aircraft Design under the leadership of Professor Rudolf Voit-Nitschmann: the solar-motor glider Icaré II (1996) and the predecessor of the e-Genius, the motor glider with a fuel cell propulsion system – Hydrogenius (2006).
An electric propulsion system also includes a power inverter, while fuel engines have a fuel system themselves. The 750 shp (560 kW) experimental magniX magni500 electric motor weighs 297 lb (135 kg), [ 136 ] while the 729 hp (544 kW) certified Pratt & Whitney Canada PT6 A-114 weighs 297 lb (135 kg), [ 137 ] both powering the Cessna 208 Caravan .
Atmosphere-breathing electric propulsion, or air-breathing electric propulsion, shortly ABEP, [1] is a propulsion technology for spacecraft, which could allow thrust generation in low orbits without the need of on-board propellant, by using residual gases in the atmosphere as propellant.

Beamed propulsion in the form of a laser can send power to a photovoltaic panel for Laser electric propulsion. In this system, if a high intensity is incident on the solar array, careful design of the panels is necessary to avoid a fall-off in conversion efficiency due to heating effects.
Due to this lower thermal velocity, chemical propulsion units become exponentially less effective at higher vehicle velocities, necessitating the use of electric spacecraft propulsion such as PPTs. It is therefore advantageous to use an electric propulsion system such as a PPT to generate high interplanetary speeds in the range 20–70 km/s.
The 1,300-shp GE Catalyst could be used in hybrid-electric propulsion: in late 2016, General Electric modified a GE F110 fighter turbofan to extract 250 kW from its HP turbine and 750 kW from its LP turbine, supported by the USAF Research Laboratory and NASA, developed and tested a 1-megawatt electric motor/generator with GE Global Research ...
The Safran ENGINeUS is a family of electric motors for aircraft propulsion developed by Safran, outputting up to 1,000 kW (1,300 hp). Design. The ENGINeUS 45 air ...
