another small breakthrough on our NERD technology.

I'll need to answer your post later tonight Derrick.  Hopefully you don't mind if I drop that PC.  I get caught up on the need to be politically correct.  And I'm evidently not much good at that.  It's a constant reminder.

MH has responded at OUR. He is correct in what he is saying. I said the same thing long ago.

There is indeed a path to ground through the FG output.

Cool stuff, this method work with a modified sine-wave inverter ?
(I need to measure the input power from the DC side for my resonant amplification experiment: all measure will be in DC to avoid error...)
Can I use it for a rectified unfiltered DC OUPUT ?


Edit: I have also a scope (DSO 2090) to get REAL power including AC (distorted dephased sine wave of course), I can use the Math function ChannelA mean * ChannelB mean ?

Hi Schubert.

I speculated wrong. The averaging method does not work for your scenario. Why? Because we are not starting with a pure DC supply such as would be the case with a battery. See the post here for a few more details:

Hi Derrick,

Apologies for the delay. 

Your circuit still looks like it has a mobius loop in those MOSFETS to me.

You've mentioned this before.  I'm going to have to read up about a mobius loop.  I'm not sure what it is.  But if it's simply that 'continuous loop' described by Wiki - then indeed.  I think you're right.  It's a wild voltage swing that never finds a balance.  But I'll check it out more thoroughly - when I've finished here.

In reference to the battery questions earlier, I KNOW that you need a completed circuit to the source to extract that potential. I thought perhaps you had somehow 'moved' that potential into your MOS 'grid' (which is why I had all those 'broken' ways to wire the circuit, see?).

Yes.  I see that.  What has now proposed that this current flows from the battery through the signal generator.  Which, in effect, is in line with your proposal.  I'll get back to this argument.

I've always found it beneficial to come to a consensus before advancing the next proposal. Lots of proposals around here but not much consensus.

Fair comment.  But my reference to those 'inconvenient truths' is simply to remind you that the basics of current analysis (literally and figuratively) has not been resolved.  Not by a long shot. And a purist would NEVER refer to current flow as a flow of electrons.  My reference to 'inconvenient truths' is a reminder to everyone that electron current flow is not so much a theory as it is an abuse of logic.  It's rather tiring reading everyone's reference to this with a kind of God like authority when it's about as appropriate as stating that the sun circles the earth.

Rosemary, have you tried building the same circuit using off-the-shelf parts?? Seems to me like that would be the best way to truly solidify your claims. Open forum projects are great until the parts start becoming too exotic/expensive... How much do those things cost?

Of COURSE - it can be built.  And it's a relatively cheap build.  I think the most expensive item are those IRFPG50's.  But, if you're seriously proposing to do this build - then email me your address - and I'll simply post you a couple.  I'm not doing any more experimenting and I've got some spare.  We over supplied as we anticipated a need.  In fact those little transistors are relatively robust.  And the only other thing I want to do related to this circuit - is a demonstration for Poynty Point and Professor Steven E Jones, when I claim their prize money. 

If you could build your circuit with cheap-o parts there would be a greater likelihood that more experimenters would try to verify your results. Makes sense right?

INDEED.  Provided only that we 'iron out' the significance of that oscillation - which is relatively easy to replicate - then it would be WONDERFUL.  It's the best possible way of getting this to the table.  Then you guys can work out how to apply it.  THAT - would be excellent.  You see, experimentation is NOT my thing. I am your ultimate clutz.  It's my only failing. 

Kindest and best Derrick

Copious changes, including switching paras and punctuation and - I think - some spelling.  Apologies. It's this early morning light and my poor eyes.  We struggle.

Hi Derrick,

I've now gone through that 1st part of that 2-part paper.  You're right.  We've not stressed that battery disconnect thing.  When it comes back from review I'll see if we can put it in.  Should be doable as it's a small edit.  Many thanks for pointing this out.  It's more or less the 'theme' of the second part of that paper.  But I think it should at least be added to the intro of the first part.

Kindest as ever,
Rosie

And I've now looked up that mobius strip.  It's mind boggling.  And strangely apt as an analogy.  A sort of bending of space.  Nicely symmetrical.  I've actually just cut a strip of paper to test it.  Can't see where it's relevant to the toroid which, apparently, is the logical extension.  But it certainly argues the logical reversal of current flow.  If that's in the context that you're seeing it.   If they could design a roller coaster like this then we'd all get a second ride for free - before we could 'dismount'.  Nice.
