What would be the possible outcomes if a connecting pipe is kept on the boundary of atmosphere and space with one end in atmospheric layer and the other in the space.. :o

After initial air pressure equalization at both ends of the pipe, not very much.
  • The end of the pipe that is in space will have a very low air pressure, matching the vacuum around it.
  • The end of the pipe that is in the atmosphere will have a higher air pressure, matching the atmosphere around it.
  • And gravity will ensure that there is a smooth gradation in air pressure between one end of the pipe and the other.

There will be no continual rush of air from the atmosphere up the pipe, and out into space, that you could use to power a generator. This would be a form of perpetual motion machine, which the Patent Office automatically rejects unless they are accompanied by a working model.

By the way, I can think of a number of very useful applications for a mechanism that is able to suspend a pipe at the outer edges of our atmosphere!

There are no such mechanisms yet I guess but I'll inform you as soon as I know of one which will.! :P  ;D

A lot of flying collisions with the pipe  :)

The atmosphere will gather at the bottom of the pipe lessening in density the further up the pipe you measure. The top of the pipe that is in space, will probably ''melt'' or something similar.

Absolutely nothing will happen. The atmosphere already extends from the ground to the edge of space, by defintion of "edge of space".
