Here is a picture using 15ft (a bit too short as you can see...) of EL Wire, powered by a single 14500 3.7v battery (the size of an AA but less heavy). The battery and inverter were taped to the center of the leading edge, and the wire threaded trough the bungies, with a piece of line supporting the bottom center. It is a bit wobbly, but I didn't have to alter the sail.
It would be better if it could be tied to the trailing edge.
The picture is from the pilot place, with 120's.
