1. Thanks for checking out my channel, you have a lot of interesting videos as well. The lifter was held down in this experiment, I didn’t want ti to fly up because it has to stay in front of the mirror for the Schlieren to work, and see the airflow.

2. it is no necessary Schlieren machine to see the ion wind under a lifter, a candle is sufficient.
   You need more voltage or more current to lift the electrokinetic apparatus.
   Townsend Brown proved his saucers in vacuum camera.

3. Thanks for the advice! I’ll give that a try as soon as I get my new Schlieren light source working. I’ve changed the way I am illuminating the mirror and hopefully will get more contrast and a clearer view of what is going on. I recently got a 30KV adjustable current power supply but in the video I was using a flyback transformer, single transistor supply I made. I don’t think the voltage was very high. As soon as I have something interesting I’ll post another video.

4. I get good charge symmetry by using the wire as a ground, and charging the foil to positive 24kV using a voltage multiplier. It’s the reverse of what’s usually done. There is very little wind felt, but the lifter will take off just as quickly and show much more stability. When the wire is given the high voltage, there’s very little control of where the ionization will take place(poor charge symmetry), and the lifter is unstable.

5. Thanks, I’m glad you liked the video. I am going to do some more experiments with ‘ion wind’ and the Schlieren setup. I agree there isn’t a whole lot of lift considering the amount of power that is being put into the system, not practical, but it is interesting. Your spinning plasma streamers sounds interesting.

6. thats pretty awesome.. thanks for showing this.. it looks like a turbulent circular thrust. ive never really thought large scale lifters to be practical as they would need way too much juice but whole category of ion wind and thrust needs to be explored.
   i remember playing with plasma streamers, especially from thin wires, then tended to want to spiral around in motion for long periods of time if u gave them a tap.

7. Thanks for checking out my channel and videos. I didn’t want it to lift up when I was making the video because it might hit the mirror or get out of view. It’s a first surface silvered mirror so it conducts and I got some arcing to it! Ouch! I’m going to do some more experiments and make some more videos to get a better understanding of how the air flows.
   Thanks again – Otto

8. Good job. I like the Schlieren photography idea. I am hoping to see your lifter actually lift up and showing the air flow patterns using this photographic technique. Finally, someone willing to show these anti-gravity buffs that the lifter does not produce gravity but it is, in fact, air flow.
