1. You cannot properly measure the output of a VDG or other ES machine by "shorting" it through a meter, since the output depends on the ability of the machine to charge to a high voltage, and shorting through a meter prevents this buildup of voltage (charge separation). The proper way is to use a moving-coil microammeter or milliammeter, connected in series with the load you are powering with the machine, said load presenting a very high impedance. I would not use a DMM anywhere near such a machine regardless of how it is connected, as I would be very worried about buildup of charge inside the meter, resulting in damage to the microprocessor and/or other delicate components. No such worries with a moving coil meter.
2. I think I see the thin transparent disk that Grum is talking about, and it is _not_ the ring of wire (with a loose end) spanning the can-lid "segments". However....
3. The Innova Tehno device is 100 percent hoax. There is no point in trying to analyze what is essentially a bit of modern art sculpture, trying to get something working. By now you should all know enough about static machines to be able to tell that all the sharp points and edges of that device would never allow buildup of sufficient charge differential to do anything useful, much less give you the "holy grail" of self-running and substantial power output. And you certainly should be able to tell the difference between the behaviour of hoaxers, and real inventors with a unique device. Open minds are good, but not so open that your brains run out your earholes, making a useless mess of timewasting and futile "experimentation".
4. There should certainly be enough power from Grum's VDG machine at high voltage to get his disk of spheres rotating, _if_ the central bearing friction is sufficiently low. You need to pay careful attention to the "stator" structures that are providing the attraction/repulsion to the spheres on the rotor, as well as providing a frictionless means of transferring charge from the stator disks or spheres to the ones on the rotor. I recommend using carbon fiber rovings, available at your local aircraft hobby shop, as brushes for this purpose. Although my Enhanced Franklin Motor is spark-commutated and optimized for rotating only in one direction, you may like to review my video of this motor. Substitute brushes of carbon fiber for the sparking electrodes, eliminate the biasing stator elements, and make sure all parts that carry charge are smoooooooth and that the only conductive paths are provided by the CF brushes themselves.
5. A much simpler corona motor may also be adequate to test Smudge's conjectures about vector potential directionality affecting rotation.
