Negative Differential Resistance Oscillator...is it OU or practical...or not? « on: 2011-09-01, 18:29:06 »

The French FE/OU researcher, J. Naudin, has investigated the following circuit(s):

(Does input and output power differ positively? Will more transistors, as Negistors, make any difference? Can a Joule Thief, Joule Ringer, Slayer Exciter, or Tesla Coil run with it in LC resonance? Do so efficiently?)

This is an archival thread for now and when I have more time to devote to it, I post additional information to it.

The thread is also "sticky", but if Members decide to post comments, they can.

J. Naudin implies the load in the demonstrated page reduces the power inputted (at bottom of page). Frequency on the 'scope remains unchanged.
