seems aluminium plates in a cell acts as a strong diode according to this video

I have tried to charge up water mist from foggers, seems to work, this is how:
(based on kelvins method of measuring atmospheric voltage gradients)
Plastic drink bottle is used, ultrasonic fogger in base, bottle sealed with selastic, two output wires from a jacobs ladder circuit are also put into the bottle.
One wire is under the water level, the other wire is above the water level.
As the water splits into droplets it absorbs charge from surrounding air, if there is a high voltage gradient from water to air, droplets should get highly charged.
Some issues encountered:
1. the fogger may turn off, when jacobs ladder circuit turned on, seems hard to tell if it will turn off or work sometimes.
One time the fogger went off at about 5 sec intervals.
I suspect the water level device is causing this, the high voltage might be causing this.
2. I had a high voltage spark occured at a point no where near the device, it arced across the base of the battery powering the fogger, I then put foam under the battery problem solved.
I suspect the piezo in the fogger might be involved in that.
Once the water charges the fog only lies below the jacobs ladder wire that is above the water,
The water mist is a good insulator, the fog droplets have air in between them, so arcing within the plastic bottle is not an issue.
Next step: work out some way to compress the charged mist to simulate compression in an engine and see if any mass release of charge occurs under compression i.e reduce the distance bewteen charged water molecules.
