DIY Hydrogen/Oxygen Generators From Grocery Store Items (HHO Fuel Cells & Split Cell Electrolysis)

I had a lot of fun doing these experiments about 12 years ago.  I ended on some conclusions.  Straight DC is okay, but when you get to playing around with pulsed DC, you can really go crazy.  I ramped my voltage up to about 5KV and was able to adjust my frequency to about 1-2 kHz and able to adjust the duty cycle as I saw fit.  Last set of toying with it was to use pure water with no electrolyte, and having a resistance monitoring system to automatically adjust the duty cycle based on water quality.  And that's when I reached the end of my skill set.  I'll hit it back up when I learn to code.

This is a huge problem, but Elon Musk’s brother has a solution...in the form of a shipping container.
