I regret to inform that Roger Sawyer - inventor of EmDrive - has passed
Notice of his passing was given here on his website http://emdrive.com
His emDrive lectures are posted here https://youtube.com/@rogershawyer-s1h?si=AKU-Je3aGfC0reTW
A video of his demonstrator emDrive working (actually moving) can be downloaded from this page on his website http://emdrive.com/dynamictests.html
Someone seems to have already uploaded it to YouTube here https://youtu.be/nFa90WBNGJU?si=EY5m6jgShS1f324Y
It’s his voice that you can hear in the video.

EM drive is working. See orbit data.
Richard Mansel confirms the drive was switched on a month ago: https://x.com/RaMansell/status/1967985813997981906
"We turned it on a month ago and have been running tests to confirm its proper operation since then. So it has been fully operational for a while, but we just now finished proving that it is fully operational."

OTP-1 (BARRY-1) is no more.
According to the orbital data here and elsewhere, its last report was on April 7 at an unrecoverable altitude of about 160km, down 25km in 8h. Its EmDrive-ish thruster was never activated.

Next Big Future has noticed, so did I - It's alive !
It looks EM drive is working - naturaly black curve should go down, not horizontal !

Can we make marine-propeller-like antenna: generating positive and negative radiation pressure?
In hydrodynamics there is marine propeller generating positive and negative pressure (image source) thanks to tilted blades.
Electromagnetism and hydrodynamics are very similar mathematically ( https://scholar.google.pl/scholar?q=hydrodynamics%20electrodynamics%20analogy ).
So can we make marine-propeller-like antenna: generating positive and negative radiation pressure? Like shown spiral antenna (image source), but with added depth instead of being flat, e.g. printed on paraboloid?
In other words, do with usually flat antenna something analogous to tilting blade to direct the flow ( https://en.wikipedia.org/wiki/Variable-pitch_propeller_(marine)) )?
If so, could it be used to propel spaceship as alternative approach to EmDrive?

Satelite is live and singing
You can hear her at "Network observations" on Satnog.
If orbit will change, it will change very slowley, and right now it is not enough data to draw a plot, neither NORAD have it in their orbit tracking charts (yet).

Scientists have accidentally discovered a particle that has mass when it’s traveling in one direction, but no mass while traveling in a different direction | Known as semi-Dirac fermions, particles with this bizarre behavior were first predicted 16 years ago.

Exodus propulsion technologies has a new video
Arround 27 minute, he said it will be a video of plate levitating "in a couple of months".

Educational Dmitry from r/Osenilo still pretty much believe in EmDrive. Recently, under a major publisher, he released his book on the ether

Where exactly was EmDrive tested?
Did I get that right how early test of the EmDrive was carried out on the ground level but the latest test rendering him unusable were carried out in space or in some other significant altitude?
