Rosemary Ainslie circuit demonstration on Saturday March 12th 2011

And anyway - on a more constructive note.  Guys.  We've got a new Tektronix functions generator.  I believe it can give a 5% duty cycle.  We'll be trying this out today and hopefully I'll have some measurements later.

hi Rosemary

if 4 out of the 5 MOSFETs are merely providing (rather unconventional) feed back to Q1 gate, how many are actually needed to achieve the same effective results (eg. as March 12)?  does it still work with, say: 4? ..3? ..2? ..1?

also, does any other particular number of 'feedback' MOSFETs appear to give a better result than 4 of them?

thanks

@poynt99 .Can you please answer a simple question for me . Preferably with a yes or a no .Do you now believe , as a result of your simulation results ,that the Rosemary Ainslie Circuit is overunity . That is to say , that it provides heat output whilst charging the batteries .

Rose,

I remember there was some suspicion that the Instek function generator may not be working properly (possibly damaged), but I thought it was subsequently determined to be OK. Is this now not the case? Is that why you now require another generator?

What model is the Tek generator you've now got?

Rosemary, you mentioned that you couldn't get that massively-long mark-space ratio to work properly anymore a few pages back - is that the reason you had to get another one, or was it just for the shorter duty-cycle?

I think we all can agree on the established fact that a net MEAN negative CSR voltage would seem to indicate a net current going back into the source battery.

A question to Rose, and any of the readers here (it would be interesting to hear any thoughts on this):

Is this apparent reversed current going back toward the source battery a consequence and product of the circuit operation itself, or is battery chemistry involved and somehow required to produce this reverse-current effect?
