Hi Evan; thanx for the previous info. You know I am investigating a
different line of application than that of magnetic motors but I just had a
thought that struck me as being useful to Newmans present day efforts. When
I built a copper magnetic motor years ago I did not follow newmans
parameters but took an entirely practical approach;I simply used rectified
ac current from 4 diodes in a full wave rectification arrangement to supply
the DC input to the coils. The next step of course was building the
commutator which confused me at first since I had never built one before.
During the building of this it occured to me that if the commutator ran at
120 revolutions per sec no diodes would be necessary to send this DC 120
pulse/sec into the coil from the AC input. The significance of this had no
practical point at that time but now I can see a new application.I have been
writing about this binary resonant system and now I have made attempts to
rectify the high voltage,high frequency signal that results from this
specially placed arc gap. When I used 25 nanosec fast recovery diodes I
obtained practically nothing out as DC output. The problem to me would be
that these diodes arent switching fast enough since 1/12 of the pulse may
appear as a short to the system which on this high inductance model
decreases the AC amperage 1800 fold. Then it occured to me that use of two
rotary arc gaps(as used in tesla coils to give an option of when the short
is supplied in conjunction with the ac waveform)could also be used in this
BRS arcgap to empty the stored charge across a load precisely for a limited
time period when the caps have reached their maximum voltage, or whatever
arrangement is found to work the best in this optional short timing
arrangement.
More importantly this discharge can be biased in one direction as to appear
as a dc pulse with a high freq. BRS signature riding on it by the use of 4
rotary arc gaps in synchony. What this implies is that a high amperage BRS
system could be used to power a Newman device by this described mechanical
commutation and the best time duration for high frequency pulsing might be
tailored according to this method. Since the amperage demands of most newman
devices are small the additional resistance of the BRS high amperage system
would be of minimal concern. I am currently assembling this kind of
arrangement to provide a 700 volt pulse @ maximum 11 amp consumption on open
circuit(infinite load) to be used for electrolysizor experiments. G Wiseman
uses a capacitor to limit amperage into these units; essentially I hope to
use a different technique of using two inductors in 60 hz resonance to limit
the amperage into the unit and harnessing a voltage gain in the meantime.
Sincerly Harvey D Norris
