The company states its Honeywell 1-Megawatt generator, at 280 pounds, weighs about the same as a motor scooter but delivers enough energy to power an entire neighborhood block. This generator will be combined with the Honeywell HGT1700 auxiliary power unit, currently flown on every Airbus A350 XWB, explains the company, to form a turbogenerator 2.5 times more powerful than the version the company unveiled in 2019.
