Author Topic: Need EE to figure out Professor Shinichi Seike's G-strain energy absorber device  (Read 25602 times)

Hi All

I've been contemplating building professor Shinichi Seike's G-strain energy absorber device as described by Jean-Louis Naudin (JLN) at:

http://jnaudin.free.fr/html/gseamnu.htm

After reading and looking at the schematics that JLN came up with I noticed that it was different than the one shown in figure 4 of the above mentioned link. 

I know that JLN mentioned "I have not been able to find the 2SC521A used by Professor Seike, so, I have used common TIP 3055 NPN transistor." but my question to all EE's on this forum is:

How did JLN go from the values listed in figure 4 of the above link to the circuit he came up with on this page:

http://jnaudin.free.fr/seike/gseav3.htm


Now to make things even more interesting I did some more sleuthing around on the web and found out that Bob Boyce commented on this device in which he had built it differently using transformers instead of the lamps that JLN used and got very different results.

This is his quote from http://oupower.com/phpBB/viewtopic.php?t=1355

"by Bob Boyce » Wed Feb 07, 2007 1:17 amHey there PalicYou may wish to try to source some NTE87 transistors. They are in a TO-3 case style, and are a better choice than the TIP3055 used by J L Naudin.In the mid 90s I built a successful replication of professor Shinichi Seike's G-strain energy absorber device using three of the NTE87 transistors as a set. I also used a set of three transformers. The outputs of these transformers were rectified and filtered, fed to a load, and back to the input as well. While running, it powered the load, and put a charge into the battery. When the battery was disconnected, the unit went into overunity runaway, quickly burning out both the load, and the transistors. I went through several sets of transistors before I eventually shelved the experiment for a later date. It was interesting to note that the heat sinks on the transistors would frost up every time, just prior to the voltage rise wiping out the transistors. It was as if a peltier effect was taking place in the transistors.Bob"

I would like to try both JLN's circuit and also Bob Boyce's circuit but I would also like to find out from anyone good in electronics how to go from the figure 4 diagrams to Bob Boyce's circuit.

Thanks in advance,

Paul

@All

I'm attaching the circuits mentioned above for comparison.

Hi all;

I just noticed that when I click the picture(s) to enlarge them it takes forever to load the schematic so I'm re-posting 2 of the schematics from figure 4 in separate posts so that everyone can see them without zooming in.

Edit: I just re-sized the image because the last one was unclear, I hope everyone can see this one clearly enough.

Regards,
Paul

Hi all;

Here's the second schematic in figure 4 which is the same components and values (I think).

Paul

I found one reference that the 2SC521A can be replaced with a MJ802 transistor.

Is this device supposed to be OU?

Geez, I think I would have pursued this with a passion (not "shelved it") if this had happened to me.  ???

@ poynt99

Thank you for your reply, I do believe this might be a project worth looking at but as far as "Is this device supposed to be OU?" I'm not sure, that's why I think that it would be worth looking into and figure out what Bob Boyce used as far as components compared to JLN's version(s).

I agree with you wholeheartedly that it shouldn't have been shelved and that's why I'm asking for help in trying to figure out from the schematics of figure 4 what Bob Boyce used in his circuit to make it work the way he claims it did.

Can you help me figure out this puppy?

Regards,
Paul

My Motorola "Bipolar Power Selector Guide" lists the 2N3716 as a "Similar Replacement".

Surely somewhere someone is claiming this device to be OU?

I simulated this circuit a long time ago when "ctglabs" was looking into it, and we determined that the wirewound resistors Seike used were causing a lot of phase shifts, and his measurements were being thrown off as a result.

But if this thing melts down with no battery attached, then that would be something worth looking at. Not sure if I believe Bob wholeheartedly though. ???

My advice would be to disregard what JLN has done, and focus on replicating what Seike built.

@ .99

What if the "wirewound resistors" were replaced with the "set of three transformers" that Bob Boyce mentioned, would that affect the circuit as shown in figure 4 ? 

Or would they help/hinder the circuit and component values? 

Did Bob have to change component values in order to accommodate the transformers instead of set of wirewound resistors/bulbs or transformers?

Sorry for all the questions but I'm not an EE and don't know much when it comes to different transistor types and component interactions.

Paul

Yes,

Replacing "R3" with the primary of a transformer would make some sense in terms of stepping the voltage up or down, but we don't know exactly what Bob used.

I doubt Bob had to make any other changes to the values when he put in the transformers.

Maybe you should send Bob a message and see if he will "remember" what he used and how they were connected.

Essentially what Seike has built is a Phase Shift Oscillator.

This was my simulation schematic.

@ .99

Thanks for your reply and input, it's very much appreciated.

I'm not sure if I or anyone else could contact Bob Boyce and that is why I posted this as a thought experiment for EE's.

I think that if Bob managed to make it work then a lot of people on this forum could probably figure out what he used for components given that it's not that complicated of a circuit compared to what I've seen over the years.

JLN does mention that the circuit(s) that he experimented with operated in the MHZ which is  supposed to be beyond the limits of the transistors but I'm not an EE so I can't tell if what he's showing is actually true but.

If Bob Boyce's circuit in self run mode had a Peltier effect  on the transistors then I would propose the following.

Make the circuit start on battery mode until you reach a self sustaining voltage then switch the circuit into the self sustaining mode for only a certain amount of time for the transistors to cool off using the Peltier effect that Bob mentioned, then after monitoring the transistors with a heat sensing device switch back to the battery until the transistor heat up again and repeat the cycle.

I hope I'm not being over simplistic in my thinking but if what Bob experienced then it shouldn't have been "shelved" without further investigation.

Regards,
Paul
