what you mean remove power? for how long it generated? vigorously?
how much power? what cell size? material?
i would love to see it ...where is the video?
I don't remember how long, but it was long enough to be a significant result. It wasn't a mind blowing amount of gas, but it was very obvious that it was still being generated even though the electricity was turned off. At that time, I was using a single cell, the inner pipe being 2" long, the outer pipe being 1" long. 314L with 304, don't remember which was which, but I think the inner tube was the 304.
At the time, I was theorizing the need for a continuous low voltage to be kept on the cell to keep the water molecules aligned. I tried this a few ways and I don't remember the specific way I had done it. But obviously it had a result. I wrote about it before here at IonizationX. At that time I called it priming the cell. The idea was it needed an initial low, continuous charge to align the water just like an older water pump may need to be primed to work for the first time. As Ronnie stated in the link I posted above, this is necessary in order to charge the cell.
He said:
You never want the voltage to fall below this voltage because it sets up the polarization process and low gas production and it can never be lost. As you can see this is a constant pulse voltage with no gating at all.
I'm trying to find the video. I watched it a few months ago, but right now I don't remember where it is. I will post it as soon as I find it.
