A SansWire sail would be of no use, in my opinion, because for a sail to function as with a sail boat it must have two mediums (like air & water as with a sail boat) moving in different directions. The SansWire will operate in one medium with no "differential" to work with. It will move with the air mass it is in with its motion modified only by the on-board propellers. However, possible horizontal sail deployment with solar panels might well augment power to the batteries.
