Does "it works exactly the same"?

yes

Your radio is not the simplest. There is the LC. The capacitor has the two
plates so on the both the voltage is doubled. No matter which one is fed to
the headphones.

Could you make the super simplest radio: "Because I have a long (150 foot)
antenna, a good ground, and a strong station (50,000 watts) less than 20
miles away, my radio receives enough power to light a low current LED. The
LED is a 'high brighness' type (which also means that it will light dimly
with a very small amount of current). I connect it instead of diode in the
radio, and it glows as the radio operates, getting brighter as the sound
gets louder. "

The super simplest radio should consist of an antenna, LED and ground.

Can we reverse the LED?

1. Zero in the sunny day,
2. Zero under the storm cloud (Franklin),
3. Zero before the storm (when the St. Elmo's fire are).

On the simplified drawing the electron flow from antena to ground.
Are you sure that the diode may be mounted in the opposite direction?

My only question is why does my crystal radio work without a ground
connection? Yes the radio does work better with a ground but that does
not negate the fact it works without a ground.

Most receivers has a chassis as a ground.

And yes the radio works
with the ground and antenna connections reversed. The diode is a piece
of galena.

yes

I haven't read all the thread.

I always see the diode in series between the antenna and the headphones.

You will get a much louder audio signal if you connect a germanium diode
( 1N34 ) in parallel with the phones.

Is the direction of the diode important?
If yes, where should flow the electrons through the diode?

No.

How many times do you have to be told that before it sinks in?

The diode (plus leads) is much longer than the total movement of the
electrons at RF. Exactly how many electrons are "flowing" through the
diode during each RF cycle?
