Hang gliders having its short kiteline to its pilot-mass moving mooring is a kite system converting winds to good effect while using the potential energy of position in a gravity system. Such systems are free-flight AWECS having option of also converting wind into sound, heat, light, electricity, and mechanical motion in tiny or large ways for various purposes.    Here is a selection of hang gliding videos with occasional annotation as readers send.  We are looking forward to announcement of RATs on HGs for various final purposes; discussion is welcome.
