I have put this in OTB because it is more serious, maybe.
Posters post an idea(in some detail), and the next poster posts an idea that is triggered by the previous poster's idea.
The idea can be about anything, obviously sticking to the forum rues...anything.
So I might as well start with the idea I had about the space station escape capsule bubble system.
It would be a system whereby someone in orbit around the earth climbs into a bag, which then inflates to say 20m radius, and it sends out a drag-line with a parachute, which brings it back into the earth's atmosphere. The largeness of the bubble might give it a low weight to air-resistance ratio slowing it down quicker, and reducing re-entry heat.
What idea does that trigger in you?
