How would you prevent the puff of gas from diffusing into nothing?
Where did you get ~35km/sec? ISS orbital speed is 7.66 km/s and it only gets slower the higher you go up.
I was thinking something similar but instead launching equivalent mass of water in the exact same orbit in the opposite direction. Right before the collision, release the water. The water would spread enough that the entire spacecraft would basically slam into a wall. The net momentum post collision should be 0. Most spacecraft debris would fall straight down to earth.

My thinking about this is that at low concentrations the gas would maintain a largely ballistic trajectory and not be subject to typical diffusion properties. Would require a purpose-built accelerator to condition for 'beam' coherency. Not sure how well that scales. > Where did you get ~35km/sec? ISS orbital speed is 7.66 km/s and it only gets slower the higher you go up. Major brain-o. Ultimately I think we're on the same page of 'kinetic deorbit', just a function of what is actually feasible.
