Disappointingly Practical and Simple EM Propulsion with off-the-shelf Parts.

We are doing such tests in our lab.
Our ion thruster is working in normal atmosphere with oxygen, the only problem is lot of ozone which is not good in higher doses.

Post some photos here, that's interesting.

Unfortunately I am changing construction a lot so it is in few pieces right now.
I need to get at least 300kV supply voltage but in small footprint.

OK, check EM drive here: http://youtu.be/GGTjy6atKMs

There is a lots of material about microwave approach in my original post in the .PDF, if you haven't read it.

As well, there is some discussion on the NASA's space-flight forum:

PDF is very interesting.
I agree with all the research, very good job.

I am afraid just about one thing of this propulsion. It can be (and actually is) extremely dangerous (power must be few orders higher than microwave owen). Radiation will be propagated kilometres from the source. There must be enormous amount of EM radiation so if it is really based on this, it can be easily detected by spectrometer.
It may cause serious issues for distant conductors - very similarly to induction cooker.

I am looking for somebody to help me with equations. I found the equations for Poynting vector pressure, but need to clarify few details.

If you are good with equations, please have a look

8.2.2 Energy and Momentum of Electromagnetic Waves

- I don't understand do these equations need to be integrated over time and over the area.
- I need solution for super-conducting donuts/toroid shape, 2-3m (6-9ft) in diameter.

On the funny side, I know the price for one of these. United Kingdom and France just paid about £4.0 million for similar size super-conductor that will balance national electricity power grid.

Well, radiation is always reported. The worst case was a lady behind Daytona Airbase. She ended 3 months in hospital and radiation burns included blisters inside eye-sockets and mouth. In Mexico City a girl just popped to a window to check what was producing the light that filled her room and she ended with small amount of sunburns. But people had died etc.

Question is more is it direct or indirect radiation. Like if it is an side-effect.
