Ah, those crazy Japanese. What will they think up next.
Oh. This. And by “this”, I mean an insanely complicated automatic door that adapts to the shape of whatever is going through it.
The main aim of this invention is to better protect a room from dust, pollen, bugs, germs etc. It could also be used for room-size freezers. In addition, it helps save the energy needed for air-conditioning.
Insanely complicated, yes. Over engineered, yes. But still, it looks pretty cool.
