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?

The colonization of the Moon and Mars remains a dream if we rely on rocketry

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.

I decided to compare the reported speed of Barry-1 against the calculated orbital velocity of Barry-1 and found a problem. My graphs are only as good as my data, and my data could be bad.

When using this source for velocity and altitude, a comparison of the reported orbital velocity and the calculated orbital velocity are inconsistent, with a 1.6 km/s difference in velocity at the current altitude. A comparison of the calculated orbital speed from mean altitude using a different source disagreed with both the original source's reported orbital speed and the calculated orbital speed from altitude.

​

The red dots are the reported orbital velocity. The blue dots are orbital velocity calculated from altitude. Both red and blue use data from the same source. Black dot is calculated orbital velocity from altitude using the mean orbital altitude from a difference source.

• Inorder for the reported velocity to be valid, the satelite must be orbiting at 530.5 km.
• Inorder for the calculated velocity in blue to be valid, the satelite must be orbiting at 503 km altitude.

I think we need to look for better sources of data if we are going to track Barry-1's progress.

Screwed up the last one. Lesson learned. Don't do maths when you haven't slept in the past two days; you might post your work.

But I went back to it and redid the graphs.

They show the last 90 days of velocity and altitude data. I think it is interesting the data shows Barry-1 stopped accelerating and the altitude is holding.

I used a rolling average because the data I have is truncate or rounded. I also use the standard deviation to show changes in the rate of change, and their scale. E.g., if the rate of acceleration changes, you will see that in the error bars, which show the standard deviation of the rolling average.

This is the source of my data.

Altitude changes for the past 90 days. Note the day 66 Std D error bars.

Velocity changes for the past 90 days.

The graphs and calculations were done in Mathematica.

It's actually quite difficult to find a useful graph showing current orbital data for BARRY-1, carrying the experimental QI drives. This is the best I've found so far. As I understand it, we want to be paying particular attention to SMA, which is the size of the orbit. If the drives work, we should see that value start to level out.

This is a very good article containing several links to relevant background information about the QI drive. I hadn't realised it had some DARPA funding.
