I'm not into revolving doors

There's a surprisingly high number of revolving door cartoons. So I guess that's a plus.Revolving doors are not a convenience. They are a nuisance. I understand that they help with indoor climate control, but seriously, they are just annoying and I prefer not to use them. Frequently, I encounter revolving doors with rugs underneath (presumably to allow one to wipe their feet while entering a building) which makes the problem even worse, as the added friction, combined with the usual poor weighting of these doors, makes it an oddly herculean effort to open a door. Ridiculous.

The purpose of a door is to provide a portal between two zones. In the case of rotating doors, those zones are almost always "indoors" and "outdoors." You never see a revolving door between two inside zones because it would take up too much space and be unreasonably difficult.

This is a good indication that revolving doors shouldn't exist elsewhere either. The space issue is usually ignorable when these doors are installed in large buildings with correspondingly large lobbies, but it's an issue nonetheless. The difficulty issue, however, cannot be ignored. These doors are harder to open, they take longer to accomplish the goal of moving between zones, and they are not worth the trouble. If a building has a large enough lobby for these doors, they have a large enough lobby that a second or so of an open door will not drastically change the temperature inside.

Whenever possible, I try to find an alternative. For example, at work, I avoid the myriad revolving doors and opt, every time, to instead use the regular doors, ignoring as I do so the message emblazoned upon the normal everyday doors: "Please use revolving door."

    Myself, I love revolving doors, though it perhaps may be because I do not encounter them in my daily life. What I like most about them is how they demonstrate economic concepts.

    For example, sometimes when the person in front of me is pushing, I don't push the door at all, thus walking through without expending any effort. This demonstrates the concept of a freeloader on a social system.

    Other times, I ponder whether it is less effort to use a consistently moderate effort to move the door at a steady speed, or if it expends less energy to start with a mighty push and then move forward on the inertia of that effort. I haven't yet figured out what the exact economics equivalency is for this is yet, though.

    However, some of your points are well-taken. A revolving door with a carpet underneath it becomes far too slow and labor-intensive to be worth it. If I could implement any improvement, it would be to be to increase the potential speed of revolving doors to (near) dangerously quick rotations per second (RPS). This would not only increase the time efficiency of a rotating door versus a regular door; it would also be much funner, which is what I think is most important quality regarding door construction.
