The internal Wing Aircraft (IWA) was invented by Robert Carr to capture the energy wasted by conventional wings. When the air passes through the unique wing configuration nearly all of the energy is used and creates the phenomenon that we call "Dynamic Natural Propulsion" (DNP™)The DNP™ effect also works in water by converting buoyancy to thrust.
