The first PNN thruster ever built outside ASPS

Dear readers, it has been a while since my last update but I think this news I’m writing is worth the wait.

In short, for the first time in ASPS history an independent scientist actually replicated on his own the PNN thruster to verify Laureti’s claims.

Scientist’s name is Jeremiah Popp, member of APEC (his bio here on APEC website).

In the gallery below you can see the pictures Jeremiah took to his experimental setup and sent to ASPS:

Here’s the detail of his setup:

Amplifier power consuption: 86W at 12V DC
SWR: 2.8@410MHz,5.6@432MHz
Frequencies tested (MHz): 400, 410, 420, 430, 432
Dipole angles tested: 25 degrees to 45 degrees
Maximum exposure 50cm away: 42V/m
Dipole ferrite temperature: ~75°C near the feed point
Dipole Litz wire temperature: ~35°C
Linear RF amplifier temperature: <60°C during each 60″ test.

Jeremiah’s thruster, as well as ASPS prototypes, is powered by a battery pack. In addition it also mounts cooling fans as active heath dissipation system.

With these conditions Jeremiah unfortunately hasn’t achieved any thrust so far and he then asked Laureti for some tips.
In a subsequent mail exchange with Gabriel Granziera (who wrote on Emidio Laureti’s behalf), it emerged that his testing setup has to be changed to match the one implemented by ASPS.

Laureti then suggested Jeremiah the following:

the input power is too low, the minimum requirement is an amplifier and a preamplifier of at least 300W. The circulating current inside the dipole arms must have at least 4-5 Amperes near the feedpoint. The low temperature of ferrites and Litz wires indicate a circulating current that is too low to produce thrust.
In comparison, the ferrites temperature in ASPS setup rises above 220°C. Active cooling system (fans) should be discharged in favour of passive dissipation (heathsinks)

Also, Laureti has some doubts about the setup of the ballistic pendulum used by Jeremiah. He then suggested him to use ASPS setup as represented in the picture below:

ASPS ballistic pendulum designed for PNN

Laureti underlined the importance of shielding the scale.. and the experimenter as well since, after all, a PNN thruster is an unshielded microwave oven.

In conclusion, Jeremiah seems to be enthusiast about PNN and he’s eager to investigate further the phenomenom and achieve the thrust and ASPS is glad about it.
In another email he writes, quote:

You fine folks should have WAY MORE ATTENTION from the public in my opinion. I’ve continued saying many great things about ASPS technology since that first APEC conference, but only a few people so far care to listen. The rest wait in heavy doubt until the experiment is repeated by a qualified third-party, and that is why I’m trying to fill the gap. I see a big future for ASPS, it’s a revolutionary technology!

I think I’m writing on all ASPS behalf if I say thank you Jeremiah for all your efforts.
We wish you good luck with your experiment, may Laureti’s suggestions make you achieve thrust.

We’re looking forward your next results.
