Of course it could be done, but replacing old batteries and/or adding
another battery would be a lot simpler and a whole lot cheaper.

Saw this on the OZ report... seem applicable to gliders!

I could see a pilot throw a line out with 50 of these on/inside a flying
tube that recharges a battery in 10 or 15 minutes. Reel the line back in
and store for the next recharge. Especially when flying wave eh?

I have a thought, I'm speaking from an airline pilot point of view and
low-time glider pilot with only a smidgen amount of aerodynamic knowledge.
But why not take the ADG (air deployed generator) that they use on some
Jets, like the DC-10 etc and make something you can deploy with a handle
(like for example a sustainer engine type thing but much smaller of course)
which could be raised (or lowered ) into the slipstream to charge batteries
when altitude or speed is not an issue - lots of excess altitude and
airspeed, popping thermals but dead or soon to die batteries. Somebody
could design something light-weight with an easily installed mechanism (on
the belly or top aft of the canopy) that can be retracted with sealed doors.
