I'm impressed by the winch/retrieve winch system I saw at Midlands
Soaring Club Long Mynd UK. they were LPG powered but elwcric would be
cool. 30-40 launches an hour. Quicker and more cost effective than a
tug

I would expect the viability to be significantly improved if
regenerative air braking in a steep descent was included by having
the propeller spinning the generator. Very rapid descents
(decreasing tug turn round) that also return energy to the battery
would be possible.
