The structure is simple: a PVC 110 mm tube in a H shape. This shape is required so the gases (H2 and O2) do not mix. If they mix, they would become an explosive solution, but separately they are much less dangerous. Just like in the illustration.

Other notes

- Must add drain.

- If test shows high temperature, I will add a radiator.

- Must add water filters to dissolve impurity.

- Alimentation will be from the 12v port through only a switch.

- Stainless steel electrodes.
