Hi All,

This was a topic at Stefan Hartmann's Forum too, see this link:

(A collection of the materials on the rods are here (included in the threads too): Index of /JapRod
(You have to be a forum member at overunity.com to see every attachment.)

The bottom line is the device shown is rather a fake than a real overunity one, unfortunately, this is the opinion of the members there.

Regards
Gyula
