I've wondered if the best way to launch is by gravity, a weight falling
into a mine shaft and attached to the glider by a cable. If you have a
supply of water then the weight is by filling a tank. At the end of the
launch you dump the water, pull the much lighter tank back up, then
refill it. Given enough room you could have a circular airfield round
the mine shaft. The only energy that you need to supply is to retrieve
the tank and cable.

A few things to sort out but it's a start

I like it!

Just get M C Escher to design the airfield and Bob's Your Uncle!
