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

I believe that there are various types of UFO propulsion.
The most familiar is for me Ion thruster which can work in atmosphere without additional gas.
It was many times proved that it just work. There is only no public research. NASA is using ion thrusters for very long time. But with current knowledge, in atmosphere it is unusable.

I found pictures of orbs that looks very real and from its construction it can be deducted that it use ions.
There are 3 rods perpendicular to each other, attached to orb while the result is assymetric capacitor.

I believe that there are good ways to boost the efficiency quite a lot for usable levels.

You will need milions of volts which is not that easy to create in compact and lightweight size. But surely it is possible with good technology.

Good you mentioned it.

I doubt that UFOs use ion trustees, because, once they are in the atmosphere the column of ions shooting out of the exhaust would glow approximately like a flame torch. As well the ion jet would burn soil and start fires etc. All of that would be reported. To make those quick turns and fast rises ion thrusters would need to be at least 4-6 orders of magnitude stronger than what we have.

Another thing, all these ions would charge up the surrounding atmosphere and UFOs would be trailed by lighting bolts and other electric discharges.

I agree with you, that there are few variants. I would like to believe that some of them are within our reach.

I am much more inclined towards microwaves, simply because majority of reliable reports point in that direction.

Actually description about glow and lighting bolts, buzzing noise as there is static electricity all perfectly matching to flying orbs.
Flying orbs are usually relatively slow. Not used for transportation but rather observing.

I am very interested in all types and experimenting with this stuff.

Lot of UFO observers reporting failing electronics, strong magnetization of metalic things, etc.

With my experiments I can change weight on small digital scale by few grams one meter away from my device based on the ion thruster.
It also causing random failures because of EM pulse with high voltage. Scale is resetting on its own, multimeter is measuring wrongly, etc.

[DROBNJAK]

That interesting.

How are you managing to control an ion jet in a normal living space?

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.
