Abstract:
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.
Abstract:
An inflatable, amphibious landing gear comprising one or more inflated pontoons with wheels attached and with one or more air bladders below each inflated pontoon. When the air bladders are inflated, they extend below the wheels and provide for water-based operations. When the air bladders are deflated they retract above the lower surface of the wheels, allowing land-based operations. Even when the air bladders are retracted they still extend below the upper surface of the wheels, so that an aircraft may still land safely on water in the event the pilot fails to appropriately configure the landing gear. The construction of the inflatable, amphibious landing gear is lightweight and of low complexity.
Abstract:
An airship or airborne station comprises a gas-containing envelope for containing a lifting gas, solar panels on the envelope for providing electric power to an energy storage system, and an external display screen powered by the energy storage system. This airship or airborne station enables novel methods of using the airship or airborne station to display digital content, to sell or auction ad space on the display screen to the highest bidder, to display information for events, crowds, rescue operations, or to interact digitally with a group of wireless communications devices. Furthermore, the airship or airborne station acts as a communication and media hub for uploading user-generated content, relaying communications from wireless devices, broadcasting content or interactive media.
Abstract:
The invention relates to a building, having an outer flexible membrane which is both supported by a frame and is air pressurizable. The frame may be of rigid construction or may be made of air inflated pressurized beams, and may be sealed by air locks. Upon activation, an air pressure generator pressurizes the interior space of the building to a desired internal pressure, providing resistance to external environmental stresses such as wind or snow loads. The desired internal pressure may vary according to the external wind stagnation pressure. The air pressure generator may be powered by an electricity supply, a battery pack, or directly powered by wind vanes. The electricity supply may driven by wind, solar power, or some other electricity source. The outer membrane may be solar cell fabric, providing the electricity source. Unused electricity from the electricity source may be stored in a battery pack.
