This door would be good up here in Canada to keep the cold out. I think they have to get a few bugs worked out though so that people don’t bang their head when walking through… Easy solution would be to make hard hat wearing manditory at your house 🙂
“Those inventors in Japan cooked up another good one. A door which opens according to the shape of the individual, animal or object that has to pass through. It also incorporates a security function that identifies people. Main purpose of the door is to save money on your heating and to keep dust and germs out.”
