And I've written this about it.. https://drive.google.com/open?id=0B0qQxFlXu7t-RGpqRk1ZYXNISkU

For the upcoming Airborne Wind Energy book.

Today though... I want to know what thickness of bungee would be needed to ...

launch a satellite from a kite network?

This video will help to frame the question So , 100 x 5000m long bungees from a ring network of kites at 10 km

F=ma = 10x11000 = 1100N per bungee 1 large kite can pull that...

A ring of 100+ or even 1000+ kites can launch a 1kg satellite...

true or nonsense?

Elastic potential of bungee = .5kx

^{2}k =spring constant x = dist stretched =~ 5000m
