Super Door of the Future

Seems to be working real well..? Or not.

OK.. seen the video and this things seems to be working a lot worse than I thought it would. Really, people are going to be hurt using this!

Really.. are we having that much problems with doors?

The Japanese are now accustomed to automatic doors. After I spent a few months there, upon returning to the US I'd sometimes wait at a public door until I remembered it wouldn't open. Thus revolving doors are expected to be automatic too. Unfortunately, making a door like that safe is tricky, and there's a very famous case of a toddler dying in a automatic revolving door (see here). I don't think anyone in Japan is going to install a revolving door for a while, what with people calling them deathtraps (even if all the issues were fixed). Ford didn't exactly release the Pinto 2.

Also, there is of course the cool factor of having a door like the one in TFA. It might attract a few more people to come into your shop. Combined with an ordinary slinding outer double-door, it could be pretty good at sealing things too.

I'll second what ultranova said - that positive pressure ventilation keeps the dust out. It's even used in instruments inside clean rooms - after probing wafers, we put them inside a small case (1 foot x 1 foot x 4 feet tall) that is even cleaner than the room (already a class 100 room - everyone in bunny suits, but no breathing apparatus)

But, mostly, entrance and exit are done with a double-door system. Open the first door, step in, close it. Then the timers activate the blowers and dust is removed from your suit. Then the inner door unlocks and you go in, freshly dusted off. There is an interlock that prevents both doors from opening at the same time.
