Window that morphs into a balcony

Something to save from inevitable upskirts at least.
I know that Pilkington made some hydrophobic layer for one of their products a while ago that meant that the rain would clean the window (or a hose), but that was years ago and doesn't seem to have found favour (I've not heard of it since).

Make a balcony, add a sliding (or pocket) glass door and done. Why would you need to convert between them?
Just lock it, and when the good weather comes, open it. Plus it seems that it will be easy to retrofit to existing apt. buildings.
If it is cheap enough, why not.
Studs are not typically designed to handle cantilever loads.
You would pull the stud right out of the wall. You'll at the very least need new (stiffer) studs. By the time you are done with the internal reconstructions (and if it's a load bearing wall, good luck), this will be very expensive.
An ordinary deck is far far cheaper. This is cool, but not practical.
