Hi Dave, to answer your question, it appears that the effect was actually the same as the pressure changed, the scientist at NASA did not think it was ion wind, instead they choose to categorize it as an EMF effect, one of them had suggested a Lorenz force effect because the power lines to the device travel in parallel paths. The other scientist did not feel they had to justify which EMF effect could account for the force.
We modeled our experiment from Dr. R.L. Talley’s 1989 T.T. Brown vacuum experiments. Like Talley we found a force would occur when the device was powered in vacuum, but unlike Talley, the device did not have to be arced to achieve the observed effect.
The motion was a rotational swing of about 70 degrees from 0 and was repeatable. Vacuums are extremely good insulators, and terrible at allowing any significant currents from the two electrodes, on average we were seeing between 3 to 12 Microamperes.
We know from our previous research that it is impossible to generate a force from these devices if there is no current flowing, the higher the current the better the effect, up to a point. We applied 41 KV to the device and still only observed 12 Microamperes and as the pressure dropped closer to 10^-7, 3 Microamperes.
It was a very clean system everything was vacuum approved so outguessing was reduced and the system was allowed to outgas overnight before they turned on the CTI cryopumps on the chamber.
As I said I have to look at our videos of the events before I can really tell all the facts.
We videotaped the device, pressure and power at the same time so its all time coded and correlated to each other, this will make the analysis easier.
Sincerely,
Hector |
