I just happen to have some platinum wire (Type B thermocouple) and I soldered it to a 9V battey cap like above. For a container, I used a mini travel size Scoop mouthwash container. I only have a HD 9V (not alkline) but I ran it for 30 minutes, and it bubbled on the positive lead the whole time. The resulting solution had more than 10 ppm chlorine (max reading on pool test strip)

To test the effectiveness, I added the solution to a glass of ice tea. I read a review of the MIOX somewhere, where it said it made ice tea clear, and removed the tea taste.

My tea ended up tasting slightly bleachy, and salty, and still very much like tea.

I'll get a fresh battery or use a power supply and try again.
