ABSTRACT:
An apparatus for capturing the exhaust stream of jet aircraft while it is being readied for takeoff and for converting the energy of this exhaust stream to useful purposes is provided. The apparatus includes a retractable funnel-shaped structure which is positioned at the start of a runway downwind of the site where an aircraft waits for takeoff and, following standard procedure, brings its engines to full power just before the start of the takeoff roll. The funnel-shaped structure, which in use is raised above the surface of the runway, captures a portion of the aircraft exhaust stream and directs it, via a first air duct, into a turbine connected to an electrical generator. Downsteam of the turbine and fluidly connected to the first air duct is a second air duct. Positioned within the latter is an air-to-water heat exchanger used to extract thermal energy from the exhaust stream for the production of hot water. When not in use, the funnel-shaped structure is lowered so that its top is level with the runway surface.
