Human Diodes

Hey. Wrong way!

The general idea is that a human diode would only allow pedestrian traffic in one direction. It would make it just downright impossible for people to walk the other way-- you would just bounce right off some kind of field. This is useful for exit-only doors and maybe makes your life as a pedestrian in a busy city a little easier by dividing a wide sidewalk into lanes. All kinds of airport, store, library etc. security features could be implemented, and maybe a controllable diode could help make sure that you can get off of a subway car before the rowdy people on the platform cram you back in.

       blowfish, great idea! I'm looking for details as to the implementation, though. In particular, I was wondering what type of unidirectional, people-repulsing "field" you were intending to use. I admit, I have an ulterior motive as I need a field like that for another project I am working on. Thanks for any information you can provide!

       Yeah, but turnstiles are so passé, the "field" thing is the future.

       How about human tunnel diodes? Or human Gunn diodes? How about human thermionic devices?

       Back in my Navy days we used to call people 'Zener' when they wouldn't do you a favor. Hehehehehe I am such a geek.   

       I want to be a light emitter.

       You're right, but give those turnstiles long enough and someone will link them to cancer.

       Is EL pedanto a human pentode (or is that *too* geekish)?

       Simple - a ruddy great fan, blowing in the direction you want to allow people to travel.

       There would however be a small, but finite, probability that any given human would spontaneously "tunnel" through to the other side though, right?
