(This has some grounds in reallity, so this very well is a post for brain storming). By not violating, i mean no creeping on others in their privatee places. Consider your selves owners of a factory which produces metallic objects which are transparent (properties similar to aluminium) what could be a product which could get you huge profits.
I would also like you to ignore the easiest option to make displays (for phones, laptops etc) which are much more tensile and durable.
You still need to put a hole into the fusalage to fit the window, which decreases structural integrity of the airframe (the reason why plane windows are rounded and not square). The ability to have a solid-piece fusalage that can just be made see-through where needed would be big improvment.
but that is also very hard
Huh? How is it hard? You question litererally gave me the power to make metal see through.
gave you power to make metal see through, not selectively. Realstically implemntation i have been thinking of is to grow directional metallic glasses, which are transparent along the less dense directions. It is mostly just all rough ideas, but i have been trying to see its potential implementations. Even partial transparency would be good, as it would be a start. This would require one more thing - making the metal non conducting (that is the issue with metals, more than them being crystalline is) - this is a bit hard (relatively), but there are some ways to fight it. One would have to do both of these. Currently mostly dreams, but hope that they can be reality some day
Alright, so we make the entire thing see through and then they can just paint it, leaving the windows out.
