There is nothing new under the sun when it comes to ground launching,
auto tow, winch, whatever. It's pretty much all been tried. Derek Piggot
wrote a book that is a great resource for learning about ground launch
in it's many forms. Unfortunately, it appears to be out of print.

ITYM "Gliding - A handbook on Soaring Flight"

Edition 7, which I have (blue cover showing a DG-800B with its motor
out), has two chapters on ground launching and is currently on offer from
Amazon for $3.60. His books may be out of print, but you can easily find
copies. Amazon even has a Derek Piggott author page.
