/r/EmDrive
Welcome to /r/EmDrive
The EmDrive (also known as an RF resonant cavity thruster) is a purported reactionless propulsion technology, which would if true would revolutionize space travel and the world economy. However, sadly, it is a pseudoscientific fraud, also known as pathological science. After nearly 20 years since its "invention", there is no compelling empirical evidence that it works as described despite ample testing of a relatively simple design and all theoretical explanations for the so-called EmDrive effect being completely at odds with our most fundamental theoretical knowledge of physics.

The r/EmDrive Rules of Participation:
This subreddit welcomes people of all backgrounds to participate in polite discourse about all things EmDrive and other radio frequency (RF) resonant cavity thrusters. We encourage scientists, builders, replicators, enthusiasts, believers, skeptics, and the like, to come together on the most active EmDrive sub and treat each other with civility. Polite banter will be tolerated. Impolite cruelty and name-calling will not.
Our full list of rules can be found here.

Q Thruster:
The fundamental difference is that CID operates entirely within known physics using measurable forces, while the Q Thruster requires theoretical quantum effects that haven't been proven to generate macroscopic forces. CID's thrust mechanism can be fully explained using classical electromagnetics and mechanics, whereas the Q Thruster relies on speculative quantum vacuum effects that would require new physics to explain the claimed thrust generation.

Arround 27 minute, he said it will be a video of plate levitating "in a couple of months".
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?

A cathode ray tube can shoot electrons from cathode to negative electrode, which is similar to the process in an electrical generator. If we have two cathode ray tubes, the tube A shoot electrons to tube B and the tube B shoot electrons back to tube A. Then the electrons have a closed circuit. If the electrons don't hit the anodes, the input power is zero. The kinetic energy of electrons can be converted to output power.
For the first time after 7-8 years, I have released all my design, build and test vlogs to the public via a sorted Playlist here:

I built a modest, crude but effective test lab and did detect about 18mN thrust with 1kW power on a horizontal beam deflector. False positives were certainly possible but I took my project as far as I could since vacuum chambers and magnetic shielding were far above my pay grade.
There are 39 videos in the play list, increasing chronologically. Binge watching might be a way to get through it all. :)
Regardless, I hope it inspires someone to build something new and exciting despite naysayers...
Does anybody have any idea what happens when EMDR is done but the present is not safe or stable? My therapist has started it with me but my home life is very y bad right now. I had a psychotic break around seven years ago and I’m pretty desperate as nothing is working. I had a lot of childhood trauma but had been extremely high functioning until age 44 when I submitted my PhD and descended into delusions. I have the original trauma and now terribek trauma from the psychosis and fall out from that.
I know patience is needed for real science to happen. I'm wondering if they have turned on the experimental thrusters yet. I don't expect to know if it works yet.
