A cristal sets has the modern name "rectenna":

No it doesn't, a 'cristal' (sic) set, fails to meet the definition that is
in the first line of the article that you linked to: "A rectenna is a
rectifying antenna, a special type of antenna that is used to convert
microwave energy into direct current electricity"; in that a 'cristal'
(sic) set does not produce direct current; as it also states later in that
article: "it discards the DC component before sending the signal to the
earphones".

And what the electrons do in such instalation:

"
a.. It is very simple to light a building with power stolen from a nearby
radio transmitter as a farmer once proved with a barn.
b.. 1. Ensure that the building is isolated and near a powerful
transmitter
c.. 2. Fit it with a metal roof (corrugated iron works well)
d.. 3. Connect the lights between the roof and a good earth connection
e.. 4. Bask in the glow
There no the "crystal" or a diode.
What do you think. Will it be working with the diode between the light and
the roof ?

Where come from the electrons?
