More on topic, Paul's original post seems to have the most practical solution.

Auto towing of an FES glider to a safe height to either fly out on FES power or allowing a safe return to the field, seems a great and practical solution.

Consider soaring sites at small airfields with neither tow plane or winch available.

Bring your glider to the site with your tow vehicle, then auto tow using the same vehicle. Think of the potential for flying from small sites.

No offense Paul, but maybe a mini winch for FES launching is a solution looking for a problem.
