Making Heavy Water - A Second Attempt - Part 1

After becoming incredibly disappointed in the fact that one of my previous projects, concentrating heavy water by electrolysis, didn't work at all after nearly two years of effort, I've worked up the determination to have another go at the extraction.

In order to make a small sample of heavy water, we'll probably need to electrolyse approximately 20 litres of water to the point where there's only a millilitre left. To do this, I put together a set of electrolysis cells in this video, altogether capable of electrolysing nearly 400mL of water per day at the desired current. (hopefully this rate of processing the water will allow me to complete the extraction in much less than the two years it took me last time)

I've made several improvements from the previous cell setup which I used last time. Mainly, the total volume of water that can be processed in one go has increased by a factor of twenty, and I'm now using a steel cathode (which apparently exhibits very good separation between hydrogen/deuterium reduction).
