Thanks for the reply, Rosemary.
Without going into the further points you made, let's just get back to the issue of the circuit in the Quantum article and what kind of duty cycle it generates.
For some reason, I seem to be the only one who has been willing to build the 555 portion of that circuit for testing. Could you, or your colleague, please confirm that the circuit shown in the Quantum article was, or was not, used to do the experiment described?
If it wasn't, what was the correct circuit?
If it was, what about the duty cycle?
Thanks very much.

(Edit: in the photos accompanying the Quantum article, it looks as though a regulated power supply is being used...and most automotive batteries in this hemisphere are rated hundreds of amp-hours, and the Quantum article and the EIT paper gives the battery capacities as 20 A-h....???)
(Edit 2: Here's a clear picture. See the diode? 1n4007, as specified. I also have tried some fast recovery diodes in this position.)
