hi GENH2,
You did not have much to look for when you wanted elements on replicas of Dave
I reproduced his cell and did tests not with the alternator but with a pulsating electronic circuit.
I know the subject of Dave Lawton well since it was me who translated it and gave his original document to Quant'homme.
What we can say is that when Dave describes the operation of his sytem with alternator it takes into account only the current absorbed by the rotor (inductor) of its alternator and not the power absorbed by the electric motor that the entrainne.
In this context it is easy to draw a favorable return.
I will not tell you everything about the tests I have done, just look at the post that deals with the topic on 2 forums where we work, I can't follow all forums and I am not working alone on this subject.

http://generation-hydrogene.forumpro.fr for this one it is necessary to present oneself in order to obtain the access.
What we can say in conclusion is that, although we have been working for many years on the subject, we have not been able to obtain superunitary returns either by trying to replicate the patents of Stan, Dave or C.Eccles with pulsed HT!
This does not mean that it is unfeasible, it is simply more complex than we thought and we are not researchers but experimenters who have trouble finding time and money to do this.
Happy reading on these two forums which represent a concentrate of all that is done on the subject in France.
