Hi Pese,

Thanks a lot for your informations. I will test this device ASAP.
You mean this king of razor blades, I guess:


You may also know that, during WW1, these blades were also used as detectors
(diodes) to build radio receivers:

In French, sorry.

jes exactly this typ of rasoir blades.
Do it in cup of water with 2 wire. (i use this with 60watt blulb (lamp in serie to the 230 volt line (as as
"fuse" . so  no problem if the blades  will move ant make short cirbuit  in the cup..

THIS SYSTEM ist used , up to date , from "prisoniers" now in Germany (possible also over the world)

----------------
This circuit for "diode" detector receiver
(as crystal-receiver, i havnt seen before

First its not to understand, because an "Diode" as an semiconductor ist - in normal way- needed.
to metals "normally" will not do this.

BUT it exist knowledges mit soft iron that is ZINC layed !!

Possibly ist is used the razoir blat as neutral, and the used secuirity pin was an ZINC  plated device.
andso its used as an Diode  (or an negative resistance) effect , that i seen in some papers before...

Only this shown me THE WAY to "understand"

P.S.
I reed the french pages.
this reclicas was done wil galenea
and another with graphit from an pen.

possibly that can used for stronger CW "morse" transmitting ro receive (1945)
WW2 again

Looking at the vidios it appears like ther is intense boiling between the two bells. The question is if it acually heats a larger volume of water as fast or faster than a conventional heater. Anyone replicating this thing for a test?

Thanks a lot for these tips (and, BTW,  the others informations)

Why couldn't a person attach wood sticks to two flat metal plates.  The wood sticks would allow a person to safely adjust the plates distance with the Mains Power on.

Of course, a light bulb in series should be used for safety.

Comments welcome.
