very unclear video, CN
An EEC must be setup like this:
1 set of 2 tubes for creating Hydroxy
On top of them with more then 0,5 inch space another set of 2 tubes.
If you use 1 tube for eec, then you need the ground of the producing tubes and you will not extract electron for the water, but from your input circuit.
So, the EEC must be a floating circuit!
