Hydrogen-regenerating solar-powered aircraft

摘要

An aircraft comprising a hydrogen-containing envelope, a water-collection system for collecting water from the envelope, an electrolyser to convert the water collected using the water-collection system into hydrogen, and a hydrogen- replenishment system for replenishing the envelope with hydrogen generated using the electrolyser. In one embodiment, generated hydrogen is also supplied to a hydrogen-fuelled propulsion system for propulsion of the aircraft.
