@geoffc huzzah. I'll have to wake up early
@uhoh the drive on Barry isn't an EmDrive, is it? It's a Quantum Inertia drive. Unless they've just renamed the same stupid thing
I agree that it doesn't sound like a terrifically scientific test. I'm presently too stupid to convert the TLEs you linked to into any kind of orbital parameters but my guess is it's pretty low
the people who made the thing (IVO) have a terrible modern webpage
I seem to recall having misgivings generally with Universe Today for something or other but they've at least got a lengthy thing on the claims universetoday.com/160516/…
the bottom of that article indicates that the described thrust/power levels violate conservation of energy. fun
NSF thread has some interesting quotes forum.nasaspaceflight.com/index.php?topic=56071.0
"One of us even worked directly with McCulloch and tested his theory down to 25 nano-newtons using a torsional pendulum, optical cavities, and a 3 watt laser. There was no thrust, only thermal noise."

@uhoh I was already mostly gonna bail on work anyway,visiting my dad. BUt totally done with work now for Friday.

The problems started with my resolution next year to reject temporal causality.

@ErinAnne it's the same asymmetric microwave resonant cavity thingamabob, they just continue to refine and polish the name.
In 2014, White's first conference paper suggested that resonant cavity thrusters could work by transferring momentum to the "quantum vacuum virtual plasma", a new term he coined.
The word "the" is so incredibly powerful. You put it in front of any word salad and the word salad becomes "real". e.g. "Did you remember to bring THE left-handed smoke shifter?"
@geoffc Does that mean that you are in NYC? Will you be around for the next Manhattanhenge?
@ErinAnne I'm happy to hear that further tests were done, and that conservation laws were not broken :-)

ehhhhhhhh. I think I disagree. They're both wrong, but Sonny White and McCulloch are wrong in different ways I think. I'd rather not heap everything at the door of Eagleworks / feet of White respectively, in part because I don't think he deserves the extra attention. Here's a debunking paper that talks about McCulloch's wrongness arxiv.org/pdf/1908.01589.pdf

now says Saturday
oof the Saturday window is only 20 minutes long
per youtu.be/dXEHWGi1WwM the next launch availability after Saturday is the 28th because of agreements about not closing the road around the Thanksgiving holiday
